About Norrstone
Built at the intersection
of trust and craft.
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.

Co-founder · CEO & General Counsel
Qualified lawyer and business graduate with 20 years across international regulatory compliance and fintech. Builds the legal, financial and trust architecture underneath every Norrstone certificate, policy and transfer.

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.
