Norrstone

For Insurers

A jewelry book
that finally has data.

Every Norrstone-bound policy comes with verified ownership, lab-grade specifications, purchase history, and an append-only audit trail. The fraud surface narrows. The underwriting confidence widens.

Verified ownership
Every policy bound against a cryptographically-anchored certificate. No more “trust me” claims of ownership.
Lab-grade specs
GIA / IGI / HRD report data flows directly into underwriting — pulled in real time from the GIA Report Results API.
Photo evidence
Claims arrive with photo evidence already attached and signed-URL gated. Faster cycle time, stronger files.
Append-only audit
Every quote, bind, premium, claim and payout is logged. SOLVENCY II-aligned audit trail by construction.
