Metal
18 karat gold. Rose gold. Platinum.
Every setting is cast in 18k yellow, white or rose gold, or 950 platinum. We do not compromise on the alloy — the metal is the frame the diamond lives in for a generation.

Assurance
Certified. Traceable. Engraved.
IGI certified
Every diamond is independently graded and certified by the International Gemological Institute — the world's largest independent gem certification laboratory.
Girdle inscription
Each certified stone is laser-engraved on the girdle with its unique certificate number, visible under magnification and linked directly to its report.
Report matched
The engraved inscription is recorded and verified against the IGI certificate, so the stone you receive is the exact stone documented.
