Color formation of chocolate diamonds
Natural fancy brown colored diamonds are sometimes referred to as champagne, lightly tinted brown, cognac or chocolate, depending on their tone. Their hue is caused by structural distortions in the diamond lattice which modifies their absorption of light. They generally show a hint of greenish, yellowish, orangey or reddish modifying colors. Internal parallel grain lines cause the brown color in diamonds. If the brown grain lines exist in a diamond that is also colored yellow by nitrogen impurities, they produce a yellowish brown color. The largest chocolate diamond ever found is the Golden Jubilee Diamond. Found in South Africa, the rough diamond weighed 755.50 carats and was cut into a 545.67-carat Cushion Cut.
Incredibly rare diamonds
In the world of diamonds, natural fancy color diamonds have a special place. Most diamonds are in the colorless to the light yellow range, graded on the color scale between D to Z. When diamonds have even the slightest hint of a color other than yellow or brown, they are classified as Fancy Color diamonds or fancies. Color diamonds are a miracle of nature and they come in incredibly beautiful shades, hues, and colors such as brown, green, blue, black, yellow, purple, pink, orange and the extremely rare red. These diamonds are very rare and tend to be found mostly as small stones below 1 carat. For every 10,000 colorless diamonds, only one natural fancy color diamond will be found.
How to determine high-quality fancies
The most important factor that determines the value of a fancy color diamond is the quality of the color. This is defined by hue, saturation, tone, and distribution. The dominant color of a stone is referred to as hue. There are also modifiers, or tints, which lend more than one hue to a stone. For instance, a yellowish-brown diamond indicates a brownstone with yellow tints. Tone assesses how light or dark a stone appears. Saturation describes the intensity of the hue or main color. The saturation of lightly toned diamonds can vary from light to intense vivid and darker diamonds will range from deep to dark in the description. Distribution refers to how evenly the color is spread across the body of the gem.
Carat weight and diamond shape
Besides color, carat weight has a large influence on the price of fancy brown diamonds. Most of the fancies are small stones usually weighing less than 1 carat. Large color diamonds of more than 5 carats are extremely rare. The shape to which the rough diamond is cut is determined by which cut will best amplify the color, the most important aspect of colored diamonds. Round cut weakens color intensity, which is why most colored stones have a fancy cut. Cushion and Radiant are the most popular cut, followed by Pear Shape, Oval Shape, Heart Shape and Marquise Cut.
