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.

Our roots

Raised in the diamond district

Don Key started on the brokering tables of LA's diamond district and grew up inside a family jewelry trade. We were among the first to bring lab-grown diamonds to the US market, and we still make every piece a few blocks from where it began.
