Black Diamonds

Black diamonds are genuine diamonds whose colour comes from dense clouds of graphite and other inclusions rather than from a trace element. They are opaque rather than transparent, and they polish to a deep metallic lustre no other stone matches.

Stones like these are graded on character rather than clarity, so choose with your eyes rather than the certificate. You can compare natural and lab-grown stones side by side here — chemically and optically identical, differing only in origin and price. Our lab-grown diamond guide explains how the two compare. They set beautifully in rubover and claw settings, and pair strikingly with white metals. Our diamond 4Cs guide covers the wider picture. Every stone is independently certified, priced transparently, and can be set into any ring in our collection or into a design of your own.
