Our diamonds
The same standard at every size.
Every diamond we set is a lab grown diamond, in D to F color and VS to VVS clarity. From half a carat upward, each stone comes with its own grading report. The laboratory depends on the size of the stone.

Certified in Seoul
Between half a carat and one, our stones are graded by an independent gemological laboratory in Jongno, the Seoul district where our pieces are made.
The certificate follows the GIA grading system across the 4Cs, with carat weight stated to the second decimal place and the proportions of the stone recorded. It ships with your piece. We hold every stone to the same standard, whichever laboratory grades it.
Under 0.5ct
Sorted to grade
The trade usually issues individual reports from around half a carat. Smaller diamonds are sorted for color and clarity by the parcel and set to specification, without individual reports. Ours are the same: sorted to D to F color and VS to VVS clarity, without a report of their own.
