Loose Lab-Grown Green Diamonds

Green is one of the rarest diamond colours in nature.

How to choose a green lab-grown diamond

Colour. Green diamonds are graded by intensity, from Fancy Light Green to Fancy Vivid Green, the most saturated and striking. Stones with a secondary blue tone show a cool, teal-like green.

Shape. Cushion cuts deepen green colour and are the most popular choice; ovals and pears give an elegant, elongated look.

Green lab-grown diamond FAQs

Are lab-grown green diamonds real diamonds?

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

Do you have green diamonds in stock?

Yes. Every stone shown on this page is an individual, certified diamond available to buy now. Because green diamonds are rare, our selection changes often.
