Trilliant Cut Diamonds
The trilliant is a triangular brilliant with either straight or gently curved sides, cut shallow so it spreads wide and throws a lot of light for its weight. Popular as a side stone, striking as a centre.
Trilliants are usually bought in matched pairs when used as side stones, and matched to the centre for colour. 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. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. Every stone is independently certified, priced transparently, and can be set into any ring in our collection or into a design of your own.
