Zarna Jewels is the fine jewellery brand of Sheladiya Diamond, diamond makers in Surat, India, since 1983. Alongside our own jewellery, we supply loose laboratory-grown diamonds to the trade, straight from our stock in India.

Cut and polished by us

Our CVD rough comes from established growers in India; every stone is then cut and polished by our own cutters at Sheladiya Diamond in Surat, the city where most of the world's diamonds are cut and polished. You buy from the people who make the stones, with no middlemen.

  • Each certified stone listed with its laboratory, report number and certificate, with photos and video of the actual stone where available.

Frequently asked questions

Are laboratory-grown diamonds real diamonds?

Yes. A laboratory-grown diamond has the same carbon crystal structure, hardness and sparkle as a natural diamond; only its origin is different, and its grading report says so. Read our lab grown diamonds guide.

Do your loose diamonds come with grading reports?

We supply both certified and non-certified stones. Certified stones carry an independent grading report from IGI or, for some stones, GIA, and the buyer portal shows each stone's laboratory and report number.

Where do you supply?

We supply jewellers, retailers, designers and manufacturers worldwide, straight from our stock in India.

How do I open a trade account?

Register on the buyer portal and upload your business documents for verification, or email care@zarnajewels.com and our team will help.
