Black Lab-Grown Diamonds
Lab-grown black diamonds deliver the same opaque, metallic black as natural stones with fully known origin and at a materially lower price per carat.
Stones like these are graded on character rather than clarity, so choose with your eyes rather than the certificate. Lab-grown diamonds are chemically, physically and optically identical to mined stones, certified to the same standards and typically 60-80% less per carat. Our lab-grown diamond guide covers the detail. They set beautifully in rubover and claw settings, and pair strikingly with white metals. Our diamond 4Cs guide covers the wider picture. Each stone is independently graded and openly priced, ready to set into one of our settings or a piece designed from scratch with you.
