About radiant diamonds
What sizes are radiant diamonds available in?
We supply radiant diamonds from 0.01 ct to 20 ct+, natural or lab-grown, as single stones, matched pairs or sets. Sizes outside that range can often be sourced or cut to order.
What is the ideal ratio for a radiant diamond?
Most clients prefer a length-to-width ratio of 1.00–1.05 square · 1.20–1.35 rectangle. Tell us whether you prefer a slimmer or fuller look and we filter stones to match.
Is a radiant available in lab-grown?
Yes. We offer radiant diamonds in both natural and lab-grown, each with an independent grading report that states its origin.
What settings suit a radiant?
Radiant diamonds are especially popular for fancy yellow, three-stone rings. We design settings around the exact measurements of your stone.
