There are so many diamond shapes to choose from when shopping for an engagement ring: round, square, marquise and more. Here’s a guide to what makes each shape special to help you pick the perfect diamond shape for your engagement ring.

First, it’s important to know the difference between a diamond’s shape and its cut. It is common in the diamond marketplace to refer to diamond engagement ring shapes as “cuts.”  Shape describes a diamond’s basic outline when viewed face up (round, square, oval, etc.). Cut, or cutting style, refers to how the diamond’s facets are arranged. For example, the most common cutting style for diamond shapes is the brilliant cut with an arrangement of 57 or 58 facets designed to maximize sparkle. So when you find that perfect emerald cut diamond engagement ring, know that what you have is actually a square or rectangular shaped diamond engagement ring.

Some diamonds, most commonly square or rectangular shapes, are step cut. Emerald cut and Asscher cut diamonds are examples. The step cut has concentric rows of facets on the crown and pavilion for a more elegant look. However, not all square or rectangular diamonds are step cut; many are brilliant cut, like the radiant and princess cut diamond.

All diamond shapes other than round are called fancy shapes. Read on to learn more about these diamond shapes:

Round diamond shapes

What’s great about round diamond shapes

Round is the most popular of the diamond engagement ring shapes, and it holds this title because the round brilliant cut is designed to produce maximum brightness, fire and sparkle in a colorless diamond. The modern round brilliant cut diamond has a round girdle outline, 56 symmetrically placed triangular and kite-shaped facets, a table facet and an optional culet facet, for a total of 57 or 58 facets.

Lapidaries have been cutting round diamonds for centuries, but it wasn’t until the invention of the bruting machine in the early 1870s that a round diamond could be more easily made with a pleasing, symmetrical outline. The first of these was the old European cut diamond, a precursor to the modern round brilliant cut but with a higher crown and greater total depth than its modern counterpart. The old European cut is still a popular choice for brides wanting an antique look.

What to look for in round diamond shapes

Symmetry is key when shopping for a round diamond to feature in your engagement ring. And if the diamond is cut as a round brilliant, as most are, pay attention to its cut quality, or how well it interacts with light. Look for brightness (often called brilliance) – the internal and external reflections of white light. Fire – the flashes of color seen as you rock the diamond under the store’s spotlights. Sparkle – spots of light that flash when the diamond moves. And scintillation – a combination of sparkle and balanced patterns of bright and dark areas. Well-cut round diamonds are brighter with more fire and scintillation than poorly cut ones, even if they’re of equivalent colorclarity and carat weight.

Avoid diamonds with extremely thin or “knife-edge” girdles or with inclusions near the girdle, which make them more vulnerable to damage.

To be certain of the quality of the cut on your round brilliant diamond, buy one with a GIA diamond grading report, which will provide an objective assessment. Look for a cut grade of Excellent or Very Good.

Rectangular diamond shapes

What’s great about rectangular diamond shapes

Rectangular diamond shapes have a long history and a reputation for classic elegance in an engagement ring. The elongated shape can make a bride’s fingers look longer and more slender. Three of the most common rectangular diamond shapes are actually modified rectangles: the emerald cut, cushion cut and radiant cut.

Emerald cut: With its crisp, sophisticated lines, the emerald cut is the most popular of the step-cut diamonds. Its four longer sides have beveled corners with two, three or four concentric rows of facets, parallel to the girdle, on the crown and pavilion. An emerald cut diamond engagement ring is a perennial favorite with the stylish elite.

Cushion cut: Adorning the fingers of brides for centuries, the cushion cut diamond has curved sides and rounded corners. It typically has a high crown, small table, deep pavilion and large culet facet. Since the cushion cut retains more color face up than a brilliant cut, a cushion cut is well suited to colored diamonds. A cushion cut diamond will be a hit with a bride who favors an antique style for her engagement ring.

Radiant cut: One of the newest rectangular shaped diamonds is the radiant cut, a modified brilliant cut introduced in 1977. It boasts the fire of a round brilliant cut diamond in a rectangular or square shape with cropped corners.

What to look for in rectangular diamond shapes

As with all diamond shapes, symmetry is important for rectangular diamonds. Facets on opposite sides should be parallel to one another, corners should be cropped to identical size and the culet should be well centered.

Emerald cuts do not hide inclusions as well as brilliant cuts due to their long rectangular facets, so high clarity is important. Emerald cuts are also less scintillating due to the step cut style of faceting. Since lots of scintillation masks lower color grades, this type of facet pattern looks best on a diamond with higher colors on the GIA D-to-Z color scale. However, it can intensify color in a colored diamond.

For radiant cut diamonds, look for brightness, sparkle and scintillation, as you would for a round brilliant cut diamond. Clarity is less of a concern, as the modified brilliant cut faceting pattern can disguise inclusions that would be more visible in an emerald cut diamond.

Square diamond shapes

What’s great about square diamond shapes

Square diamond shapes in engagement rings are perfect for the woman with long, slender fingers who wants them to look shorter. They are also a statement of individuality for a bride who would appreciate a contemporary alternative to the classic round brilliant cut. Want a square shaped diamond in your engagement ring? In addition to the square versions of the cushion cut, emerald cut and radiant cut diamonds described above, consider the princess cut or Asscher cut.

Created in 1981, the princess cut diamond has a modified brilliant facet arrangement that gives it electrifying sparkle and scintillation. For a very different, but surprisingly modern look, the Asscher cut – first introduced in 1902 but since modified for greater brilliance – is similar to a square emerald cut but with larger step facets, a higher crown and a smaller table. Unlike the pointed corners of the princess cut, the corners of an Asscher cut are cropped, giving it the appearance of an octagon.

What to look for in square diamond shapes

Again, look for good symmetry. Facets should match on either side of an imaginary line drawn down the middle of the stone. Look for a balanced contrast of light and dark patterns in the table and other facets.

Fine princess and Asscher cut diamonds will not have a culet facet, which must be taken into consideration when mounting the stone. The culet is a safety facet that helps protect the point on the pavilion from chipping when the diamond is loose or if it is exposed in a setting. In addition, for the princess cut, it is important to choose a prong or bezel setting that protects the pointed corners.

As with emerald cut diamonds, the Asscher cut is most effective for diamonds that are colorless (D–F on the GIA color scale) or colored diamonds.

Marquise diamond shapes

What’s great about marquise diamond shapes

An attractive, elongated shape with a royal pedigree, the marquise (pronounced “mahr-keez”) was supposedly named for the Marquise de Pompadour, a mistress of King Louis XV, as its outline resembled the shape of her mouth. Because of its shape, a marquise diamond ring will look larger face up than a round diamond of the same weight. A marquise diamond engagement ring can also make the finger appear longer and more slender.

What to look for in marquise diamond shapes

Several factors must be considered when choosing a marquise diamond for your engagement ring. You want a marquise that is neither too long (and thus may sacrifice brightness and pattern) or too short (“stubby”) and thus loses the benefit of length to your bride’s finger. The points at either end should be sharp.

Note the regal gentility of this 0.91 ct marquise diamond and the two smaller marquise side stones. Courtesy: 1stdibs.com

Symmetry is extremely important for marquise diamonds. Both sides (wings) should have the same amount of curve, and the facets on one side of that imaginary line down the center of the diamond should match exactly the shape and size of the facets on the other side. Since the tips of a marquise diamond are where it is most vulnerable, it is not unusual for them to have slightly greater girdle thickness. If the marquise diamond is prong set, choose V-shaped prongs for the tips. A well-cut marquise will typically display a minimal to no bow-tie pattern.

Oval diamond shapes

What’s great about oval diamond shapes

Although a shape that is many hundreds of years old, the oval diamond has gained popularity for engagement rings in recent years because of its elegance and the fire it shows when cut in the brilliant faceting style. In addition, with its greater surface area, an oval diamond may appear larger than a round brilliant diamond of the same weight (and, like rectangular and marquise diamonds, can help elongate shorter fingers). One advantage over other fancy shapes is that the rounded edges make it less prone to chipping.

What to look for in oval diamond shapes

Pay attention to proportion. Longer oval diamonds are preferred by some, but they are not practical to cut so tend to be harder to find.

As with other fancy diamond shapes, symmetry is essential to ensuring beauty in an oval diamond. Again, placing an imaginary line down the length of the diamond and then across its center, the shape and faceting of the two halves should be identical.

Also look for a graceful outline and the size and nature of the bow-tie pattern. The bow tie on a well-cut oval diamond will be minimal or non-existent.

Pear diamond shapes

What’s great about pear diamond shapes

An irresistible blend of the marquise and round brilliant, the pear shaped diamond is a stylish choice among diamond shapes. Worn with the point toward the tip of the finger, its graceful, tapered shape can make the hand look slimmer and more elegant, perfect for an engagement ring.

What to look for in pear diamond shapes

Pear shaped diamonds come in a variety of proportions, so there are many options for choosing one that flatters the finger. Look closely at the wings on either side of the point to make sure they are symmetrical, with the rounded end a good semi-circle. Since the point is the weakest feature, look for (and avoid) inclusions in that area. If prong setting the diamond, use a V-shaped prong on the point for greater protection.

As with oval and marquise diamond shapes, the bow-tie pattern on the table should be minimal, or better yet, non-existent.

Heart diamond shapes

What’s great about heart diamond shapes

The heart shaped diamond is the essence of romance. It is also a very flattering style for larger fingers.

What to look for in heart diamond shapes

There are good reasons why this is one of the rarest of diamond shapes for engagement rings. A well-shaped heart requires a large diamond, at least one-half carat. In addition, inclusions tend to be more prominent in this shape, so you want a diamond that has good clarity. Symmetry is also key: The well-rounded lobes should match in size and shape, as well as faceting style, and the cleft between them (as well as the point) should be well defined.

With its graceful, tapered outline, a pear shaped diamond is an elegant and flattering choice for an engagement ring. Here are the essentials for selecting the perfect pear shape.

  1. Learn the anatomy of a pear shaped diamond
  2. Look for symmetry in a pear shaped diamond
  3. The ideal length-to-width ratio is the one you prefer
  4. Check culet placement and position of inclusions
  5. Make sure the table is centered on a pear shaped diamond
  6. Avoid the bow-tie on a pear shaped diamond
  7. Choose a setting that protects the point of a pear shaped diamond
  8. Point up or down? You decide how to wear a pear shaped diamond

1. Learn the anatomy of a pear shaped diamond

Jewelers consider the pear shaped diamond a “fancy shape,” meaning it’s a shape other than round. Reminiscent of a tear drop, a pear shaped diamond blends the best of the round and marquise diamond shapes.

Since the parts of a pear shaped diamond contribute to its beauty, you should get to know them. Then you can shop for a pear shaped diamond engagement ring with a discerning eye.

Look at the diamond face-up and pay attention to its outline. A pear shaped diamond should have gently rounded shoulders and wings. The wings should form attractive arches. If they’re too flat, they make the stone look too narrow. If they’re too rounded, they make it look short and stubby.

The pear shaped diamond, like the round brilliant diamond, is faceted to deliver the most sparkle and brilliance. Here are the names of important parts of a faceted diamond, which you should know and are used in this blog:

  • Culet: The culet is a small facet at the bottom of the pavilion of a finished gem intended to prevent chipping and abrasion of the fragile tip. Some gems have no facet in this area, which is often called a closed culet.
  • Crown: The top part of a gem located above the girdle.
  • Girdle: A narrow band that circumscribes the edge of the plane separating the crown and pavilion.
  • Pavilion: The portion of a polished gem that is below the girdle. The purpose of pavilion facets is to reflect light toward the crown.
  • Table: A large facet in the center of the crown.

Like many other fancy shapes (such as the marquise or heart shape), a pear shaped diamond tends to hold more color than a round brilliant. Therefore, it is best to choose a diamond that is high on the GIA color scale or a fancy-color diamond.

2. Look for symmetry in a pear shaped diamond

Symmetry is key to the overall beauty of gemstones, but it’s even more important in some fancy-shape diamonds like oval diamonds, heart shaped diamonds, marquise diamonds and pear shapes. To see if a pear shaped diamond is symmetrical, draw an imaginary line down the length of the gem and examine the two halves. The more closely they mirror each other, the better the symmetry is.

Notice how the shoulders, bellies and wings in the illustration below are identical on either side of the line, and how the shape, size and placement of the facets in each half of the stone mirror one another. This is an ideal pear shape. You can use the illustration as a guide when picking a pear shaped diamond.

When GIA diamond graders evaluate the symmetry of fancy-shape diamonds, which includes pear shapes, they also look for things like a balanced and even outline. Certain types of asymmetry and uneven proportions are considered by most in the jewelry trade to have a negative effect on the appearance of a pear shaped diamond. These include:

  • High shoulders
  • Flat wings
  • Bulged wings
  • Undefined points

Uneven shoulders and uneven wings are other variations that will detract from the appearance of a pear shaped diamond. The illustration below has both.

Illustration showing an uneven outline of a pear shaped diamond with asymmetry in its shoulders, belly and wings.

The uneven outline of this pear shape reveals the asymmetry of its shoulders, belly and wings. You might want to avoid a diamond cut like this. Illustration: GIA

3. The ideal length-to-width ratio is the one you prefer

You might run into the phrase “length-to-width ratio” (comparison of the length and width of the outline of many fancy-shape diamonds, determined by dividing the diamond’s length by its width and stated as a ratio, like 1.75:1). Many experts prefer a length-to-width ratio that lies in the range of about 1.50–1.75:1. Others in the trade believe that a ratio isn’t enough to convey a diamond’s beauty. You may want to let your heart and eye guide you.

4. Check culet placement and position of inclusions

The placement of the culet on a pear shaped diamond can affect its appearance. It should be the same distance from the two sides of the diamond. A culet that is off-center will affect the diamond’s symmetry and is likely to make it less attractive. In some pear shapes, the culet is included in a keel line that extends down the length of the diamond where the pavilion facets meet. Like the culet, the keel line should be equidistant from either side of the diamond.

An Illustration of a pear shaped diamond showing an off-center culet.

The culet on this pear shaped diamond is off-center. It should be symmetrically placed at the same distance from either side of the gem. Illustration: GIA

Note, too, whether the diamond has any inclusions, especially near its point, as this is the area of that is most sensitive to damage. In addition, if the pear shaped diamond has a larger table facet, inclusions could be more apparent, so good clarity is a consideration.

5. Make sure the table is centered on a pear shaped diamond

A poorly placed table facet can also make a pear shaped diamond look less attractive. For maximum brightness and fire, the table should be centered on the line of symmetry.

An illustration of a pear shaped diamond showing an off center table.

If the table is off-center, the crown facets on one side of the pear shaped diamond will appear larger than the facets on the opposite side. Illustration: GIA

6. Avoid the bow-tie on a pear shaped diamond

Many pear shaped diamonds show a dark pattern that resembles a bow-tie. This pattern typically runs across the width of the stone from the center of the table. The bow-tie on a well-cut pear shaped diamond should be minimal, but there will still be good contrast between light and dark areas in the stone.

A bow-tie can vary from light gray to black. The darker or larger it is, the more it detracts from the face-up appearance of a pear shaped diamond. A bow-tie gets darker as the difference between a diamond’s length and width increases and pavilion angle variations (the measured angle between the pavilion main facet plane and the table plane) become more extreme.

If you find the bow-tie effect distracting, be sure to examine a variety of pear shaped diamonds from different angles under the lighting conditions in which the engagement ring will be worn. You may not be able to avoid a bow-tie altogether, but you should be able to find a stone in which it is subtle.

7. Choose a setting that protects the point of a pear shaped diamond

The most vulnerable part of a pear shaped diamond is the point. This area can be protected by placing a V-prong on the point or choosing a bezel setting around the entire stone.

8. Point up or down? You decide how to wear a pear shaped diamond

The traditional way to wear a pear shaped diamond engagement ring is to have the tip pointing away from you (down). According to many in the trade, this makes the finger look more slender. But tradition has its limits. Some brides choose to wear this shape with the point toward them (up). And some prefer a horizontal setting that gives this classic diamond shape a distinctive, contemporary look.

Like all matters of the heart, let yours decide which way the pear should point.

Among the most elegant of the fancy shapes, a pear shaped diamond conveys both the delicacy of a single tear and the strength of the brightest star. While there are many factors to consider when searching for the perfect stone for your diamond engagement ring, it is a journey well worth taking. When deciding between different pear shaped diamonds, the overall appearance is more important than the specific proportion details. Often, what makes a pear shaped diamond attractive is a matter of personal taste. So enjoy looking at different pear shaped diamond engagement rings until you fall in love with the perfect one.

Before you go shopping, be sure to read our 12 tips for buying an engagement ring.

A radiant cut engagement ring is an irresistible combination: It has the fire of a round brilliant diamond and the aristocratic elegance of an emerald cut. Created in 1977, the radiant cut has been charming brides-to-be for decades.

A relative newcomer to the ranks of fancy-shaped diamonds, the radiant cut can be square or rectangular; notably, it has cropped corners and brilliant-cut facets. Diamonds with less-than-exceptional clarity can be good candidates for radiant cut engagement rings: In addition to giving the stone plenty of sparkle, this brilliant-cut faceting pattern disguises inclusions that would be more readily apparent in an emerald cut.

Buying a Radiant Cut Engagement Ring

Radiant cut diamonds have broad appeal. Elongated stones can create the effect of slenderizing fingers, while shorter styles can flatter even the most petite hands. To determine which proportions work best for you, we recommend trying on various options to find the perfect radiant cut engagement ring.

Important characteristics to look for in any radiant cut diamond are a well-centered culet, parallel sides and corners cropped to identical size.

The enchanting sparkle and alluring appearance of radiant cut diamonds makes them especially attractive as solitaires. And they don’t require extra embellishment to stand out from the crowd: Taste-making celebrities like Megan Fox sport the cut.

The radiant cut diamond also pairs well with side stones. Shapes with straight edges—like trilliants, or baguettes and other rectangular stones—are popular in radiant cut engagement rings because their linear silhouettes are complementary. And while you’ll often see radiant cut diamonds oriented north-to-south in engagement rings, the east-to-west orientation is gaining in popularity.

A baguette diamond, usually set in multiples, adds a dash of style to an engagement ring – or any jewelry piece. Popular since the Art Deco era, this dazzling diamond cut should be part of your shopping vocabulary. Here’s what you need to know.

In this blog, we cover:

Baguette Diamond: A Definition

Baguettes are small, usually rectangular, step-cut diamonds with straight or tapered edges. Some baguettes are almost square, while others have a length-to-width ratio of 5:1 or even longer. A tapered baguette diamond has long sides that angle inwards. Baguettes are popular side stones in engagement rings.

Emerald cut diamonds are also rectangular or square step cuts. Unlike baguettes, though, they have diagonally cut—not square—corners.

In a style called the ballerina setting, baguettes surround the center stone to form a skirt that resembles a ballerina’s tutu. While the tutu effect is best shown with tapered baguettes, so the skirt appears to flow out from the girdle of the center stone, other diamond shapes have also been used. For a ballerina setting, baguettes are typically channel set, though they are occasionally prong set.

An attractive novelty cut is the brilliant baguette. This is primarily a mixed cut, with brilliant-style facets (triangular and kite shaped) on the pavilion and step-cut facets on the crown. A benefit of this style is that it can add more sparkle to your diamond engagement ring.

Dimensions are more important than weight when purchasing baguette diamonds, since they are usually sold in multiples. For example, if you were purchasing two of them–to sit on either side of a center stone–you or your jeweler would ask for two stones of equal dimensions – and not of equal carat weight.

 

Baguette Diamond: A Brief History

The origin of the term “baguette” for these small step-cut diamonds is up for debate. The traditional translation of the French word is “rod” or “stick,” but one meaning given in Randle Cotgrave’s 1673 French and English Dictionary is “a little jewel.” It is the diminutive of the French “bague,” which at the time meant “jewel” or, its current meaning, “ring.”

The rectangular step-cut diamond now called the baguette diamond is believed to have evolved from the hogback, an elongated table cut that was known since at least the mid-16th century. At that time, it was often used to make monograms and jeweled letters (like the owner’s initials). Cartier reintroduced the baguette cutting style in 1912, and in the following decades jewelry designers of the Art Deco period favored its clean lines and geometric shape. It was in the 20th century that the term “baguette” was first used in English to refer to this popular side stone as we know it today. Some think that the diamond cut was named after the long, thin loaf of French bread that it often resembles.

The baguette diamond is frequently used in contemporary jewelry and engagement rings. So if you want a modern version of an Art Deco engagement ring, consider one with baguettes.

Baguette Diamond: What to Look For

Here are some tips for picking beautiful baguette diamond:

  • All the baguettes in the ring should be similar in color and clarity, and they should match the center diamond. A baguette diamond whose color or clarity is noticeably different from another or from the center stone is likely to create an inharmonious and unappealing appearance.
  • Step cut means that the crown facets of the baguette are arranged in a terrace-like fashion parallel to the table edges. Slight deviations in the facets’ symmetry are usually visible to the naked eye and detract from the stone. Make sure all facets are parallel and symmetrical.
  • Avoid inclusions – they are usually more visible in a baguette diamond than a round brilliant.
  • Baguettes and tapered baguettes are purchased in sets. For simple accent stones on the shoulder of a ring, you may want one, two or three (for example) baguettes or tapered baguettes on each shoulder. They will need to match in length and width (and taper) to fit the channels. For straight baguettes, you will need to specify the length and width to 0.1 millimeter (mm) for a good match. For tapered baguettes, you’ll need to specify the wide and narrow end widths to 0.1 mm.
    To create a long curve, buy the appropriate number of tapered baguettes that range in length from X to Y, depending on the type of width range you want that curve to be. The stronger the taper, the sharper the curve, so ask for diamonds with a slight or strong taper.
  • Like most other diamonds, baguettes can be treated to enhance their appearance. Treatments may include high pressure, high temperature (HPHT) to enhance color or fracture filling to enhance apparent clarity. Synthetic diamond baguettes are also available in the marketplace. By law, a retailer must disclose if the diamonds you are purchasing are natural, treated or synthetic.

Cushion Cut Engagement Ring — What to Look For

Cushion cut diamonds — both antique and modern — have curved sides and rounded corners. Part of the charm of cushion cut diamonds is their variety. Some have elongated, rectangular proportions and others resemble rounded squares. There’s also a great diversity in the arrangement of their facets that affects their appearance. In addition, this style is well suited to fancy-color diamonds.

Some cushion cut diamonds have all the fire of round brilliant cut diamonds, while others have a more subtle glow. As when choosing any diamond, try on a number of rings to find your favorite. A beautiful cushion cut is symmetrical so the opposing sides should mirror each other.

Anatomy of an Oval Diamond

An oval diamond is a fancy shape. You can think of it as a round brilliant diamond stretched on its sides, or a rounded version of a cushion shape or cushion brilliant. To pick a beautiful oval diamond, you need to know its parts.

Head or end: The “tips” of the oval.

Shoulder: The curved area reaching from the head/end to the belly.

Belly: The central area where the sides curve out the most.

You’ll typically find oval diamonds cut in the brilliant faceting style, which means the diamond has 57 or 58 facets, like a standard round brilliant, giving it similar visual qualities. An oval diamond can have a variety of facet arrangements, but the most common is eight bezel facets on the crown combined with eight main facets on the pavilion.

There are compelling reasons why many people love oval diamonds: Because the oval diamond has a larger surface area than a round diamond of equal carat weight, it can appear larger to the eye. The oval shape can make the finger seem longer. And because the shape doesn’t have sharp angles or corners, an oval diamond is less prone to chipping compared to other fancy shapes.

History of the Oval Diamond

The brilliant faceting style was first introduced circa 1700. Brilliant-cut cushion shaped diamonds predominated because cutters tended to follow the outline of the rough crystal. But diamonds were available in a variety of shapes, including oval. At this time, diamonds were not described by their shapes – they were simply called “brilliants.” It isn’t until the late 1800s that we first see mention of oval diamonds in literature.

Modern appeal for the oval diamond began in 1957. The oval diamond enjoyed a resurgence between 1998 and 2001, driven in part by marketing campaigns, and now it’s making a comeback. According to Town & Country magazine, the oval diamond ranked 6th in popularity with American consumers in 2016 (round diamonds were still no. 1).

Famous Oval Diamonds

The 105.60 carat (ct) Koh-i-Noor is probably the most famous oval diamond. It was so valuable that it was said that “whoever owned the Koh-i-Noor ruled the world.” Following centuries in the possession of rulers from Persia and India, the diamond was presented to Britain’s Queen Victoria on July 3, 1850. It is now set in the Queen Mother’s crown, which was fashioned for Queen Elizabeth, wife of George VI (and mother of Elizabeth II), for their 1937 coronation. You can see it in the Tower of London with the other Crown Jewels.

The 31.06 ct Wittelsbach-Graff (long known as the Wittelsbach Blue) is another famous oval diamond with a royal provenance. The rough probably came from India’s famed Golconda District. In about 1666, it was given as part of a dowry for the marriage of Infanta Margarita Teresa of Spain into the House of Hapsburg. In 1722, it was used again as part of a dowry, this time for a marriage into the House of Wittelsbach. In 1931, the Wittelsbach Blue vanished from sight and was hidden for 30 years, until it was rediscovered in 1961. After it was sold at auction for $24.3 million in December 2008 to London Jeweler Lawrence Graff, the original 35.56 ct cushion modified brilliant diamond was recut to a 31.06 ct oval to make it a Fancy Deep blue, Internally Flawless gem, and was renamed the Wittelsbach-Graff.

Another oval diamond made international news in April 2017, when Hong Kong jeweler Chow Tai Fook bought a 59.60 ct Internally Flawless, Fancy Vivid pink diamond for $71.2 million. Known to many as the Pink Star or Steinmetz Pink, it became the most expensive diamond ever sold at auction. The retailer renamed it the CTF Pink Star. The diamond was mined in Botswana in 1999. It took cutters two years to turn the 132.50 ct rough into its final shape.

What to Look for in an Oval Diamond

Turn to the 4Cs of diamond quality when shopping for an oval diamond. GIA uses the same criteria for determining carat weight, color and clarity for oval diamonds as it does for round brilliants. This can help you narrow your search.

Length-to-Width Ratio

Keep proportion in mind when looking at oval diamonds. Consumers and trade professionals tend to prefer a longer oval shape, according to a comprehensive survey of shape preferences GIA conducted in 2009. The survey showed that the most popular length-to-width ratio for ovals was 1.7:1. However, it is not practical to cut such long oval diamonds from the original rough, so you’ll rarely find one. More typical are ovals with ratios ranging from 1.3:1 to 1.4:1.

Symmetry

Symmetry is important in creating the beauty of an oval diamond. To determine if an oval diamond is symmetrical, draw an imaginary line down the center. The shape and faceting of the two halves should mirror each other. Then draw an imaginary line across the middle of the oval. Again, the shape and faceting of the two halves should be identical.

Shape Appeal

Look for an oval diamond with a graceful outline and harmoniously proportioned parts. To find one that’s attractive to you, it pays to compare several different oval diamonds. Here are some common shape variations:

An oval diamond with no shoulder bulge

This oval cut has no shoulder bulge. Its overall symmetry and well-proportioned shape contribute to its visual appeal. Image: Al Gilbertson/GIA

Girdle Thickness

The girdle is the intersection of the crown and pavilion. It defines the perimeter of the diamond and functions as its setting edge. Girdle thickness is judged the same way in fancy shapes as in rounds. Be sure to look at the diamond’s proportion diagram in its GIA Diamond Grading Report. The diagram will show the stone’s average girdle thickness percentage and indicate if the girdle is too thick or too thin. An overly thick girdle can contribute to a heavier diamond than its face-up appearance warrants, and a thin girdle can increase the risk of damage such as chipping.

Bow-tie Effect

Expect to see a bow tie. A “bow tie” in diamond parlance is a dark bow-shaped pattern across the table of the diamond.

What causes a bow tie? A diamond’s facets act like a series of mirrors that gather light from around you and return it to your eye. As you look at the stone, the dark contrast you see is a reflection of your head and shoulders blocking light from entering the diamond. The closer your face is to the diamond, the more pronounced the bow tie will be.

If the diamond is cut well, the bow tie will be minimal, but once you are in front of the diamond, there will always be some measure of a bow tie.

Oval Diamond Engagement Ring Settings

You’ll have lots of choices for engagement ring settings for oval diamonds. And each setting can create a dramatically different look. Here are some options.

Halo Setting

A halo of smaller diamonds around the oval center stone is a lovely addition. It accentuates the shape and makes the diamond appear larger. Choosing a different color of metal or side stones can create an arresting look.

Prong Setting

Prong settings are good choices for an oval diamond. Not only do they protect the diamond from loss, but they can also add height, raising the diamond from the band and drawing the eye to the gem.

Bezel Setting

A bezel setting, which completely encloses the perimeter of the diamond in metal, is a great choice if you lead an active life. It’s an effective way to protect the diamond and also enhances the beauty of the oval shape.

Side Stones

An oval diamond goes well with virtually any kind of side stone. Half-moon diamonds echo its shape, so they can be an attractive choice. Baguettes and tapered baguettes offer an opportunity to create contrast, as do colored gems. If you want your diamond side stones to match the center oval, choose side stones that are within one or two color grades of the larger diamond so they don’t compete with its beauty.

Wide Band

Because of its shape, an oval diamond works well with a wider band.

An oval diamond is beautiful…classic…and a little different. It’s a wonderful option for an engagement ring.

If you’re looking to create a diamond engagement ring that’s out of the ordinary, there are many more fancy shapes to choose from. A marquise diamond just might be for you.

Princess cut engagement rings are relative newcomers on the diamond engagement ring scene. They’ve gained popularity for their breathtaking brilliance and fire. Discover this distinctive diamond, known for its attention-grabbing sparkle.

The princess cut is among the newest diamond cuts—especially when compared to round and cushion styles that have origins dating back centuries. This stunning cut was first developed in 1979, and is second only to the round brilliant cut diamond as the top choice for engagement ring diamonds. Its royal name “princess” undoubtedly contributes to its appeal. If you are looking for a special diamond, a princess cut engagement ring offers a tremendous amount of brilliance and beauty.

It’s not difficult to understand the attraction of this striking diamond cut. Unlike emerald cut engagement rings and other square- or rectangular-shaped diamonds that feature a step cut faceting style, princess cut diamonds have a modified brilliant facet arrangement, offering both electrifying sparkle and a strong, attention-grabbing shape.

How to Find the Right Princess Cut Engagement Ring Diamond

For the most appealing appearance, consider the diamond’s length-to-width ratio. To be called a square princess cut, the ratio cannot exceed 1.05:1. Rectangular princess cuts can have various ratios, but commonly they are no greater than 1.25:1.

Beyond shape, symmetry influences the desirability of a princess cut stone. When viewed from above, faceting should match on both sides of its midpoint, both vertically and horizontally. The importance of symmetry applies below the girdle as well. When a princess cut diamond is turned face down, the faceting and shape of each side should mirror the side opposite.

The Princess Cut Engagement Ring: Setting Considerations

Princess cut diamonds are often set as elegant solitaires to show off their arresting beauty. Side stones featuring crisp, angular lines—such as triangles or baguettes—can enhance the presentation of a princess cut diamond. This cut adapts well to a variety of settings, though its straight contours seem an obvious fit for contemporary, architectural diamond engagement ring styles.

When shopping for a princess cut engagement ring, it’s important to realize that the sharp pointed corners that contribute to the diamond’s bold geometry are also areas that are vulnerable to chipping. Choosing a setting with four V-shaped prongs, eight prongs with two at each corner (called split prongs), or a bezel setting will keep the corners unscathed and preserve a princess cut diamond’s regal profile.

An added bonus to this striking diamond cut may be its price. You may find that princess cut diamonds cost less per carat than comparable round brilliant cut diamonds. That’s because the cutter is able to retain more of the original diamond crystal.

So whether you select a princess cut for a diamond engagement ring because of its distinctive shape or its brilliant sparkle, your future bride will feel just as regal as her diamond’s namesake.

A heart-shaped engagement ring is unabashedly romantic and the perfect symbol of love. But did you know that heart-shaped diamonds are relatively uncommon in diamond engagement rings?

There are many reasons for this. Perhaps top among them the fact that the heart shape works best for larger diamonds – those that are at least one-half carat in size. But although uncommon, heart-shaped diamonds are having their moment in the spotlight. If you have your heart set on a heart-shaped engagement ring, read on for some tips to help you pick the perfect one.

Heart-Shaped Engagement Ring: It’s All about the Outline and Symmetry

The outline needs to reflect a traditional heart shape. You may find some that have pointed lobes or very flat wings, rendering an outline that resembles an arrowhead. Symmetry is a key indicator of quality in a diamond of this shape. (After all, who wants an off-kilter sign of affection?) Both left and right sides of the heart should match in size and shape, although it’s not unusual for the width of the diamond to be greater than its length.

Here’s a helpful tip you can use when you’re in a jewelry store:
1. Draw an imaginary line down the center of the diamond you’re eyeing.
2. Check to see if both halves of the heart match in size and shape, from cleft (the center V-shaped region) to lobes (the rounded portions) to point.
3. A symmetrical heart-shaped diamond should also have a length-to-width ratio of 1:1 to 1:1.2.

You’re likely to see a number of heart-shaped diamonds that are asymmetrical. Examples of this include a poor length-to-width ratio, misshapen wings and an undefined point. Take a look at the asymmetrical heart-shaped diamond below.

Asymmetry detracts from the innate appeal of a heart-shaped diamond as the high shoulders, flatish wings and short length-to-width ratio of this stone illustrate.

Heart-Shaped Engagement Ring: Clarity Counts

Clarity characteristics can be easier to spot in heart-shaped diamonds. It’s best to look for a stone with good diamond clarity. Avoid diamonds with eye-visible inclusions that could diminish their beauty and affect their durability and value.

Heart-Shaped Engagement Ring: Settings

Most heart-shaped engagement rings are relatively simple in design: streamlined styles emphasize the special silhouette of the diamond’s shape, which offers plenty of drama on its own. Consider classic solitaire settings or elegant halo designs that trace the outline of the central diamond in small, pavé-set stones.

As a practical matter, it’s smart to look for a diamond engagement ring that shields the point of a heart-shaped diamond, since it’s the part of the stone most vulnerable to damage. Once you’ve found the heart of your dreams, you’ll want to protect it.
