Lab Diamond Radiant

This collection holds loose radiant cut lab grown diamonds, from under one carat to large center stones. Every listing gives the carat weight, color and clarity. You can choose colorless stones from D to H color or fancy colored stones in blue, pink, green and yellow, and some listings are marked as IGI certified.

Why choose a radiant cut

A radiant cut has the clipped-corner rectangle or square outline of an emerald cut, but with brilliant facets that give lively, sparkling light. The clipped corners help protect the stone, and the shape works for both modern and classic rings. Lab grown diamonds share the same chemical and optical properties as mined diamonds.

How to choose a loose radiant lab diamond

Decide on the outline first: some radiant cuts are nearly square, others are long rectangles that make the finger look slimmer. Then compare color and clarity. D to F stones look icy in white gold, while G and H look a little warmer and suit yellow or rose gold. Radiant cuts look strong in a lab diamond solitaire ring, framed by a lab diamond halo ring or flanked by side stones in a three stone ring.

FAQs

Can I have a loose radiant diamond set in a ring?

Yes. Choose a stone here and a design from our lab diamond engagement rings, and the ring is made to order.

What is the difference between radiant and emerald cut?

Both have clipped corners, but a radiant has brilliant facets for more sparkle, while an emerald cut has step facets for a calmer look.
