Cohort 1 · 2026
Become a pilot partner.
We're onboarding our first cohort of jewelers in Iceland and the Nordics. If you're ready to own the full customer lifecycle, we'd love to talk.
The Problem
Jewelry is valuable. Digitally, it's invisible.
The relationship ends at checkout
The customer walks out and you never hear from them again. No lifecycle data. No repeat revenue signal. No way back in — unless they choose to return.
→ Norrstone keeps you connected to every piece, forever.
Paper certificates get lost
GIA, IGI, and HRD reports end up in drawers, lost in moves, or thrown away. When resale or insurance comes up, the piece has no history. Value evaporates.
→ Norrstone issues a permanent digital certificate at point of sale — it never gets lost.
90% of jewelry is uninsured
A €10,000 ring walks out the door with zero insurance. Without verified ownership, your customer can't insure it — and you can't help them.
→ Norrstone certificates unlock insurance in one tap — and earn you a commission.
No verified resale infrastructure
Without provenance, a €10,000 ring resells for €4,000. Your customer loses. You lose the referral. The market loses trust.
→ Norrstone provenance commands premium resale — and you earn a share of every transaction.
How It Works
One certificate. Multiple revenue layers.
Issued automatically at point of sale. No manual work. No friction for you or your customer.
01
Issued automatically at point of sale
The Norrstone certificate generates automatically the moment you complete a sale — through Shopify or your POS. Zero manual work. Zero friction. It just happens.
02
Stored in the customer's Norrstone Vault
Your customer instantly receives their personal Vault — a permanent digital home for their certificate, purchase receipt, and every service that follows: insurance, resale, transfers.
03
Unlocks insurance, loyalty, and verified resale
The certificate becomes a living asset. It connects your customer to insurance in one tap, enables verified resale with full provenance, and keeps bringing them back to you.
04
Your certificate keeps earning
When the piece changes hands — through resale, inheritance, or trade-in — you earn a commission. Every certificate you issue becomes a long-term revenue asset.

Why Now
EU Digital Product Passport Regulation Is Coming
The EU's Digital Product Passport regulation is not optional. It applies to jewelry and luxury goods, with mandatory compliance beginning 2026 and full enforcement by 2030. Every piece you sell will need a verified digital record. Norrstone issues that record automatically — at no extra step for you or your customer.
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.
Underwrite a Norrstone-bound book.
We're selecting one EU insurance partner for the 2026 jewelry pilot. Lower fraud surface, real-time grading, EU-hosted infrastructure.
Norrstone is building the digital infrastructure for trust in the fine jewelry industry. Jewelry is one of the most valuable and emotional purchases people make — yet ownership, certification, and post-sale relationships remain fragmented and largely offline.
Founded in Reykjavík — where craft, trust, and quality have been synonymous for centuries. Our Nordic roots inform everything: understated design, regulatory rigor, and an absolute commitment to doing things properly.
The Founders
Co-founders. Equal partners.
A jeweler and a lawyer building the trust layer their respective industries have asked for. Both names on the company. Both names on every decision.

What We Stand For
I
Trust as Infrastructure
Verification isn't a feature — it's the foundation. Every certificate, every transfer, every resale request is underpinned by cryptographic proof.
II
Craft Deserves Continuity
A piece of fine jewelry outlives every piece of paper. Our certificates are designed to last as long as the pieces they protect.
III
Open, Not Proprietary
Norrstone is designed as open infrastructure — standards-compatible, integrable, and built to connect the industry rather than lock it in.
