Diamond Color

This refers to the presence or absence of color in white diamonds. Color is a result of the composition of the diamond, and it is permanent.

Fancy color diamonds do not follow this rule. These diamonds, which are very rare and very expensive, can be any color from blue to green to bright yellow. They are often more valuable for their color.

To grade 'whiteness' or colorlessness, most jewelers refer to GIA's professional color scale that begins with the highest rating of D for colorless, down the alphabet to Z, to grade stones with traces of very faint or light yellowish or brownish color.Diamond Color

What is Fluorescence?

Fluorescence is an effect that is seen in some gem-quality diamonds when they are exposed to long-wave ultraviolet light (such as the lighting frequently seen in dance clubs). Under most lighting conditions, this fluorescence is not detectable to the eye – and often it may even improve the brilliance and color of the diamond. Diamonds with fluorescence can often be bought at a discount because of a perceived negativity towards fluorescent diamonds.
