About trillion diamonds
What sizes are trillion diamonds available in?
We supply trillion diamonds from 0.01 ct to 10 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 trillion diamond?
Most clients prefer a length-to-width ratio of 1.00–1.05. Tell us whether you prefer a slimmer or fuller look and we filter stones to match.
Is a trillion available in lab-grown?
Yes. We offer trillion diamonds in both natural and lab-grown, each with an independent grading report that states its origin.
What settings suit a trillion?
Trillion diamonds are especially popular for side stones, modern solitaires. We design settings around the exact measurements of your stone.
