How It Works
One identity.
A lifetime of services.
Norrstone turns a valuable physical asset into a persistent digital identity, then connects that identity to ownership, insurance, service, trade-in, resale, and transfer.
01
Physical asset
A jewelry piece or watch enters Norrstone through the jeweler, watchmaker, or an approved verification workflow.
02
Persistent digital identity
Specifications, imagery, issuing merchant, laboratory data, and supporting documentation form one enduring identity.
03
Verified ownership
The record enters the owner’s private Vault and remains associated with the current owner through future transfers.
04
Connected services
Insurance, claims, service, warranty, trade-in, resale, and transfer can work from the same asset identity.
05
Lifecycle continuity
The record continues with the piece, preserving context for the next service, insurer, transaction, and owner.
The foundation
Evidence,
held together.
The certificate establishes the identity of the piece. The platform keeps that identity, its permissioned data, ownership, and connected services in continuity.
