COLOR Refers to the degree to which a diamond is colorless.
Diamonds range in color from icy winter whites to warm summer whites. Diamonds are graded on a color scale established by the Gemological Institute of America (GIA) which ranges from D (colorless) to Z.
Warmer colored diamonds (K–Z) are particularly desirable when set in yellow gold. Icy winter whites (D–J) look stunning set in white gold or platinum.
Color differences are very subtle and it is very difficult to see the difference between, say, an E and an F. Therefore, colors are graded under controlled lighting conditions and are compared to a master set for accuracy.
Truly colorless stones, graded D, treasured for their rarity, are highest on the Diamond Quality Pyramid. Color, however, ultimately comes down to personal taste. Ask a jeweler to show you a variety of color grades next to one another to help you determine your color preference.
