KimeGem

Know the story behind your diamond certificate. A grading report can confirm that a report number exists, but it cannot tell you how many people are claiming the same diamond identity. KimeGem helps you register your report numbers, strengthen your claim with privately reviewed evidence, and monitor for possible conflicts. Register and monitor Scan a QR code or barcode, or enter your grading report number manually. Once the number is verified with the grading authority, it can be included in private conflict matching. Build your trust score KimeGem uses three verified stages: • T0 — Lab verified: the grading authority holds a record for the number. • T1 — Card verified: a reviewer confirms that the physical grading card matches the report. • T2 — Ownership verified: invoice and jewellery evidence support the claim. Evidence uploads are optional. Claims advance only after review. Receive private conflict alerts If another verified claim uses the same report number, KimeGem can notify both sides. You can see the other claim’s trust score and approximate claim date without exposing the claimant’s identity. Your evidence stays private Certificate and ownership evidence is encrypted and never made public. KimeGem uses private matching rather than an open ownership search. Free to join Register report numbers and receive duplicate alerts for free. Add your numbers early and build a stronger verified claim over time. Important: KimeGem is not a diamond authentication service, appraisal, valuation, or legal determination of ownership. A verified trust score reflects the evidence reviewed; it does not guarantee that a diamond or ownership claim is genuine.
