When selling your diamond to a purchaser, color is always taken into account when determining its quality and value. The rarer and brightly colored stones are worth a premium as are the colorless diamonds. White diamonds are assessed using colorless diamonds as an industry standard and categorized on the GIA diamond grading system. Gem diamonds in GIA’s D-to-Z range usually decrease in value as the color becomes more obvious. Just the opposite happens with fancy color diamonds: Their value generally increases with the strength and purity of the color. Large, vivid fancy color diamonds are extremely rare and very valuable. (The exception to this is fancy color diamonds, such as pinks and blues, which lie outside this color range.) Most diamonds found in jewelry stores run from colorless to near-colorless, with slight hints of yellow or brown. GIA’s color-grading scale for diamonds is the industry standard.
