Certified natural diamonds in Japan: read the report

For a GIA-graded loose diamond, compare the report number, measurements, color, clarity and disclosures with the proposed stone. If you require a GIA or CGL report, tell the team before selection. The laboratory, report type and availability are checked for each candidate; a grading report is not a financial appraisal.

Fancy shape diamond jewelry and unusual cuts

Explore preferences for radiant, cushion, Asscher and pear shapes, among other distinctive diamond cuts. For exotic shape diamonds in Tokyo, consider face-up dimensions, proportion and the intended setting. A description such as “cut-cornered rectangular mixed cut diamond” should be checked against the individual grading report rather than treated as an interchangeable shape name.

High-clarity VVS and VS natural diamonds

VVS and VS clarity preferences are considered alongside color, cut, carat weight and the stone’s appearance. Compare the location and visibility of features as well as the grade. The right balance depends on the jewelry design and the qualities that matter to you.
