the hope diamond

Often when picturing a diamond, we envision the classic colorless gem depicted in films, showcased in engagement rings, or displayed with other popular jewelry in glass cases. A colorless diamond is the clear, classic diamond we envision. Many “colorless” diamonds possess very subtle hints of yellow or brown, colors that can affect the value of the stone.  But diamonds come in colors that extend beyond the D-to-Z color scale. And when the color of the stone is strong enough, the diamond becomes known as a “fancy-color diamond.” (more…)

When it comes to diamonds, most consumers tend to use the words “cut” and “shape” interchangeably.  But for diamond professionals, there is a big difference.  Diamond Shape refers to the outline of the stone (pear, oval, round, etc.).  Diamond cut refers to a stone’s facet arrangement.  So a shape can be faceted in a variety of ways, or cutting styles.

The June birthstone, the pearl, has a long and rich history. For many young women, pearls are just something you wear when you wanted to look classy and put together.

anatomy of a diamond

When a diamond interacts with light, every angle and every facet affects the amount of light returned to the eye. The sparkle of a diamond, then, has everything to do with how well the cut of the diamond was planned and executed. Although a diamond’s value is based on its unique combination of color, clarity, cut, and carat weight (the 4Cs), a diamond’s cut is the most complex to assess, and it’s the only component that can be directly affected by the diamond cutter.
