Types of Diamonds: Pink, Yellow, Blue, Green Diamonds
Diamonds come in many different colors. Although a truly colorless stone is very rare, the rarest colored diamonds are the most deeply tinted and thus more expensive than colorless diamonds. Colored diamonds are referred to as "fancy diamonds" because of their fancy colors, and often have their own grading scales depending on color. White diamonds, for example, use a 10 point scale and range from D, which is best quality of color, to Z.
Blue diamonds are graded on a Very Light, Light, Fancy Light, Fancy, Intense, Deep, Dark, and Vivid scale and can have secondary colors such as green and grey. Secondary colors often make colored diamonds less valuable. In recent years, yellow and
pink diamonds have grown in popularity. Although tints of yellow are associated with flaws in colorless diamonds, a truly vivid canary diamond, as
yellow diamonds are called, can be quite rare. The Yellow diamond grading scale goes as such; w-x light yellow diamond, y-z light yellow diamond, fancy light, fancy, fancy intense, and fancy vivid. The most desired secondary colors with canary diamonds are green and orange. Pink diamonds often have a very light color saturation as opposed to the deep pink and nearly purple shades of pink sapphires and rubies. Champagne diamonds have a cognac coloring and grade C1 and C2 stand for a light champagne coloring, C3 and C4 in the medium range, and C5 and C6 as a dark champagne tinge. C7 is reserved for the fancy cognac diamond. Green is the rarest color for diamonds. Green diamonds are created when natural radiation comes into contact with the stone during its formation. However rare, market prices of green, and all colored diamonds, are determined by consumer preference.
