FANCY COLORED DIAMONDS EDUCATION
More rare than a colorless diamond, a fancy color diamond is truly the most brilliant and exotic stone that comes from the earth. Your gemologist at Krikawa specializes in rare shapes and colors of fancy colored diamonds. Consider a colored diamond to make your Krikawa ring truly unique.
of a natural color diamond is nothing short of a miracle. In addition to the extreme conditions that must be present for a diamond to form inside the Earth, minute amounts of trace elements must also interact with the carbon atoms to permanently alter the color. It is estimated that a diamond has only a 1 in 10,000 chance of possessing any natural color, regardless of the spectral hue, which makes any fancy colored diamond a true natural wonder.
grades can be assigned to fancy colored diamonds the same way as diamonds in the colorless range, however, clarity is not one of the most important factors in determining the value of natural color diamond. It is a consideration in the valuation, but not a critical factor. In other words, a natural color diamond with deeper color and lower clarity is considered more desirable than one with lighter color and higher clarity. Often times, the unaided eye cannot detect inclusions in a fancy colored diamond because these characteristics blend in with the diamond’s color.
is also not considered a critical factor in valuating a natural color diamond, since the diamond is typically fashioned to enhance the color as much as possible while retaining the maximum amount of weight from the rough crystal. This practice lends itself to brilliant cut styles, as opposed to step-faceted, with deeper cut proportions and thicker girdles on finished diamonds. The most common shapes found in large fancy colored diamonds are radiant cuts and cushion cuts.
Though rounds are by far the most popular shape for diamonds in the colorless range, fancy colored diamonds do not hold color as well in this shape. Premium-Ideal cut proportions in rounds can improve the "face-up” color of a diamond in the normal range, but will actually cause the strength of the color in a fancy colored diamond to appear weaker due to the way light performs.
Strength of Color
Diamonds in the colorless (D-Z) range usually decrease in value as the color becomes more apparent. The opposite is true with fancy-colored diamonds. In fact, the single most important value factor that affects the rarity of a fancy colored diamond is color. Fancy-colored diamonds are found in nearly every color of the rainbow. Red, green, purple, and orange are the rarest colors, followed by pink and blue. Yellow and brown are the most common fancy colors; therefore, they are the most affordable. Aside from the spectral hue, the purity and strength of the color also affect rarity.
refers to the dominant color of the stone, such as pink, blue, or yellow. There can also be modifiers, or tints, which impart more than one color to a stone. For instance, a purplish-pink diamond indicates a stone with a principal pink hue and a slight purple tint. If no modifiers or tints exist in a stone, then the hue is said to be pure.
refers to how much lightness or darkness a stone appears to retain. The range of tones goes from light to dark.
describes the strength or intensity of the hue. The saturation of light diamonds can very from pastel to vivid and intense. Dark diamonds can range from dark to deep.
Fancy Yellow Diamonds
Light to vivid yellow diamonds are found in different countries. The saturation of color is dependent upon the amount of nitrogen present. The largest and most saturated yellows have been discovered primarily in South Africa. These include the largest known yellow diamond, the Red Cross, which weighs 205.07 carats, and features a Maltese Cross visible from the top facet.
Fancy Pink Diamonds
Pink diamonds come in a variety of colors, including bubblegum and coral. There are also brownish and purplish pink diamonds. The Argyle mine in Australia is the only mine in the world that produces a consistent volume. A whole year of Argyle's intense pink diamond production can be held in the palm of one hand. To put the true rarity of these stones in perspective, of every million carats of rough diamond production at Argyle, only one carat is suitable for sale in its tender.
Fancy Blue Diamonds
Fancy blues range from very light shades through to a steel blue hue, and derive their color from boron impurities. Due to the presence of boron, some blue diamonds are able to conduct electricity! The Cullinan mine near Pretoria, South Africa is the world's only notable blue diamond producing mine. The Hope Diamond, arguably the most famous diamond in the world, is a natural fancy blue, weighing 45 carats. This deep blue diamond is now at the Smithsonian Institute in Washington DC.
Fancy Green Diamonds
Only a handful of green diamonds are introduced into the market each year. Pure green diamonds are valued more than those which are yellowish-green or gray-green. Fancy green diamonds are sourced from South Africa and other parts of the continent. The green color comes from being near radioactive sources during formation. This process takes at least a million years to occur, hence their rarity! The most famous green diamond is the 41 carat Dresden Green Diamond, currently housed at the Staatliche Kunstsammlungen in Dresden.
