Questions

Why an estimate and not a set price?

Two stones with the same grades can differ in cut, measurements and face-up look. We source from a large IGI-certified supply, so we send you the actual stones that fit your request, each with its own report and exact price.

Are these lab-grown diamonds?

Yes. Every stone is a CVD lab-grown diamond: real diamond, chemically and optically the same as mined.

Do the diamonds come with a certificate?

Yes. Stones 1 carat and up come with an IGI report, plus a Don Key certificate of authenticity.

Can I get a stone bigger than 3.5 carats?

Yes. Larger stones are available on request. Choose 3.5 ct+ and send us your request.

Can you set the diamond for me?

Yes. We set loose stones in custom rings, pendants and earrings in 14K or 18K gold. Custom pieces take 2–4 weeks.
