Radiant natural diamonds

The radiant pairs the crisp outline of an emerald cut with brilliant faceting, so it sparkles like a round diamond in a rectangular or square shape. Radiants hide small inclusions well. Choose the ratio you like: close to 1.00 for square, 1.20–1.35 for a rectangle.

About radiant diamonds

Every radiant diamond below is a real, individually graded natural stone from live inventory, shown with its own photograph or video where the supplier provides them. Prices are live and rechecked before anything is confirmed.

Radiants look striking in solitaires and hidden halos, and in three-stone designs with trapezoid side stones.

Questions

What is a good length-to-width ratio for a radiant diamond?

Radiants hide small inclusions well. Choose the ratio you like: close to 1.00 for square, 1.20–1.35 for a rectangle.

Are these diamonds natural?

Yes. Every centre diamond we offer is a natural, mined diamond graded by an independent laboratory, and the laboratory is named on its certificate.

Can I buy the diamond on its own?

Yes. Choose “Or buy this diamond on its own” on any diamond page, or set it in one of our 18K gold settings.
