Fancy Lab-Grown Diamonds

Lab-grown fancy colours are produced by introducing the same elements nature uses — boron for blue, nitrogen for yellow — under controlled conditions. The result is the colour of a stone that might occur once in a million, at a price that reflects the process rather than the accident.

For strong pinks, blues and greens the price difference against natural runs to orders of magnitude, which is why lab-grown dominates this end of the market. Our lab-grown diamond guide covers how they are made; our diamond 4Cs guide explains how fancy colour is graded. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
