Fancy Red Natural Diamonds

Fancy red diamonds are the rarest diamonds in existence — fewer than thirty certified pure reds are known worldwide, and like pinks their colour comes from lattice distortion rather than a trace element.

At this level of rarity, natural stones trade privately; lab-grown red offers the colour without the scarcity premium. These are natural stones, formed over billions of years and mined under traceable, conflict-free supply chains. Read what makes a diamond ethical before you choose. Colour is graded on its own scale for fancy diamonds rather than the D-to-Z scale — our diamond 4Cs guide explains how that works, and our diamond shapes guide shows how each outline carries colour differently. Each stone is independently graded and openly priced, ready to set into one of our settings or a piece designed from scratch with you.
