How to choose a yellow lab-grown diamond

Colour intensity. Yellow diamonds are graded from Fancy Light Yellow through Fancy and Fancy Intense to Fancy Vivid Yellow, the saturated canary yellow that is most sought after. Stones with a secondary brownish tone have a warmer, golden look; see also our champagne diamonds.

Shape. Cushion and radiant cuts intensify yellow colour and are the classic choice for canary diamonds. Oval and pear shapes give a graceful, elongated look.

Clarity and certification. Almost all of our yellow diamonds are VS clarity or higher, and every one comes with an independent IGI report.

Yellow lab-grown diamond FAQs

Are lab-grown yellow diamonds real diamonds?

Yes. They are real diamonds with the same chemical, physical and optical properties as mined yellow diamonds, grown in a laboratory instead of being mined.

Yellow diamond or yellow sapphire?

A yellow diamond is harder (10 vs 9 on the Mohs scale) and has far more brilliance and fire than a yellow sapphire. Read our guide to yellow sapphire vs yellow diamond.

Our loose lab-grown yellow diamonds start from £340, with price rising with carat weight and colour intensity.
