GRA (Moissanite)

Certifies carat, color, clarity and cut. Certificate number matches the laser inscription on the stone girdle.

Independent grading report for HPHT and CVD lab diamonds.

SGS (Workshop audit)

Incoming material inspection, in-process patrol and final 100% check documented per batch.
