Decoding Color: The GIA Colored Diamond Color Grading System

When does yellow become orange, and orange become red? The question may sound a bit philosophical until you tie it to colored diamonds, where slight variations in color can mean huge differences in price.

When you’re shopping for a diamond, its brightness and sparkle will draw you to the jewelry counter, and keep you captivated long after you’ve made your diamond purchase. Achieving maximum brightness and sparkle requires excellent cutting technique, which is reflected in the diamond’s cut grade. Of the 4Cs, no other ‘C’ has more impact on a diamond’s appearance.


Crazy for Colored Diamonds
