Color formation of blue diamonds
Fancy blue diamonds are usually classified as either blue, grayish blue, greenish blue turquoise or aquamarine. The color of blue diamonds is caused by the presence of boron atoms. The higher the concentration of boron, the more intense the color. In Argyle blues, which are usually gray-blue, the color is related to the presence of hydrogen and also to that of nitrogen. The most famous blue diamond is the Hope diamond with an amazing 45.52 carat weight. It changed hands many times on its way from India to France to Britain and to the United States. After exposure to ultraviolet light, the diamond emits a red glow-in-the-dark affect fueling its reputation of “being cursed”.
● The colors of fancies
In the magical world of diamonds, natural fancy color diamonds hold a place of their own, next to their colorless counterparts. Most diamonds are in the colorless to the light yellow range, on the D to Z color scale. Fancy color diamonds (fancies) go off this scale and even the slightest hint of a color other than yellow or brown will qualify the stone as a fancy colored diamond. Color diamonds are a miracle of nature and they come in incredibly beautiful shades, hues, and colors such as blue, green, yellow, purple, pink, orange, brown, black and the extremely rare red. Unlike colorless and near colorless diamonds, fancies are valued for the intensity and distribution of color. These diamonds are extremely rare and tend to be found mostly as small stones below 1 carat.
● Hue, saturation, tone, and distribution
Color is the most important factor that determines the value of a fancy color diamond. Color is determined by hue, saturation, tone, and distribution. Hue refers to the dominant color of a stone. There are also modifiers, or tints, which lend more than one hue to a stone. For instance, a greenish-blue diamond indicates a blue stone with green tints. Tone represents how light or dark a stone appears. Saturation describes the strength or intensity of the hue or main color. The saturation of lightly toned diamonds can vary from light to intense vivid. 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
After color grade, carat weight has the most effect on price for fancy blue diamonds. The majority of fancies are smaller stones, usually weighing less than 1 carat. Large diamonds of 5 or more carats are extremely rare in fancy color diamonds. The shape will be determined solely on the basis of that which will best amplify the color, which is the most important characteristic in fancy color diamonds. A Round cut dissipates color, which is why most colored stones have a fancy cut. Radiant and Cushion are the most popular cuts, followed by Oval Shape, Pear Shape, Heart Shape and Marquise Cut.
