Certificate of Authenticity
Every piece comes with its own record.
Before a stone is set, our bench on Hill Street grades it by hand. Each piece ships with a printed certificate and a QR code that opens its record online, for as long as you own it.
- Cut, color, clarity and carat, graded by hand
- A unique certificate ID, linked by QR code
- Look it up, print it or share it any time
Certificates are issued and graded in-house by Don Key.
