All Lab Grown Diamonds

This is our complete range of loose lab grown diamonds: thousands of individual stones, each with its own listing that shows the shape, carat weight, color and clarity. Buy a stone loose for your own design, or choose one as the center of a custom ring, pendant or pair of earrings.

Shapes and Colors

You will find round, oval, pear, princess, cushion, emerald, radiant, heart and marquise cuts, plus specialty shapes such as trillion and antique cuts. Alongside colorless grades, the collection includes fancy color lab grown diamonds in pink, blue, yellow and green. Many listings name their grading laboratory, such as IGI, so check each listing for its certificate details.

How to Choose a Loose Lab Grown Diamond

Start with the shape, then balance carat weight, color and clarity. Our diamond size chart shows how different carat weights look, and our comparison of moissanite, lab grown and mined diamonds explains how the stones differ. Elongated shapes such as oval, pear and marquise tend to look larger for their weight, while round brilliants are cut for maximum sparkle. If you already know the setting style you want, browse our lab diamond engagement rings or lab diamond solitaire rings.

FAQs

Are lab grown diamonds real diamonds?

Yes. A lab grown diamond has the same chemical, physical and optical properties as a mined diamond; only its origin is different.

Can I have a loose diamond set into jewelry?

Yes. A stone can be set into a custom engagement ring, pendant or earrings, handcrafted to order. See our lab diamond pendants for ideas.

Is every stone certified?

Not every listing names a certificate. Where a grading report is available, its details are shown on the stone's listing.
