    Understanding diamond certification

    A grading report describes the stone it was issued for.

    Eligible main stones can be IGI certified. Read the individual product details and ask us to confirm the report for your selected stone. Small melee and pavé stones are not presented as individually certified. A report for a centre stone does not certify every stone in the finished piece.

    Are pavé stones individually certified?

    No. We do not claim that melee or pavé stones each carry an individual grading report.
