About Fancy Colour Natural Diamonds

Fancy colour diamonds are among the rarest and most sought-after gemstones in the world. Unlike traditional white diamonds graded on a D-to-Z colour scale, fancy colour diamonds are valued for their intense, vivid hues - from canary yellow and champagne to pink, blue, and green.

At Diagem, every fancy colour diamond is independently certified by GIA or IGI, with colour grade, intensity, and origin clearly documented. Whether you're a collector, investor, or looking for something truly unique, our fancy colour selection offers certified quality at factory-direct pricing.
