GIA Certification Service

Let us help you send your stone to the GIA!

GIA is the foremost authority in authentication and grading of diamonds and gemstones. They will also be able to tell you any and all treatments, and for an additional fee, the origin of your stone on request.

This GIA report is not an appraisal. We can help you determine the value once we receive the GIA report.

This fee includes insured shipping of one gemstone to and from the GIA, and authentication of the gemstone. Does not include an origin report. The timeline is approximately 6 weeks.
