Sarine Token — Blockchain-Backed Digital Identity for Polished Diamonds
Sarine Token — Blockchain-Backed Digital Identity for Polished Diamonds
Sarine Technologies' tokenisation layer linking physical stones to immutable on-chain records
Sarine Token is the digital tokenisation and traceability platform developed by Sarine Technologies, linking each physical diamond to a blockchain-based digital token that carries the stone's identity, provenance, and certification data. Sarine Token is part of the Sarine Connected ecosystem, alongside Sarine Diamond Journey, Sarine Loupe, and Sarine AI grading, and is intended to provide a secure, immutable record that travels with a stone through trade and ownership transfers.
The mechanism
Each tokenised diamond is bound to its on-chain record by a combination of optical fingerprint data and the digital files generated during Sarine's manufacturing-stage imaging — Galaxy inclusion maps, polish-stage Loupe images, and the AI grading dataset. The token is a cryptographic record, recorded on a permissioned or public blockchain depending on the deployment, and serves as a tamper-evident identifier that can be presented at any subsequent point in the stone's life. Sarine has positioned the system to support secondary-market trading and ownership transfers as well as initial retail.
Industry context
Tokenisation in the diamond trade addresses two practical problems. The first is fraud: a tokenised stone with a complete imaging record is harder to substitute or misrepresent than one carrying only a paper certificate. The second is digital commerce: as more diamond trading moves online, a digital identity that the buyer can verify independently has commercial value beyond what physical inspection can provide. The De Beers-backed Tracr platform addresses similar ground using blockchain on the rough side, while Sarine Token operates principally on polished stones at retail.
Adoption and limitations
Adoption has been concentrated among manufacturers and retailers who have already invested in Sarine's imaging infrastructure, where Token is a natural extension of an existing workflow. Outside that installed base, the trade has been cautious. The fundamental question is whether buyers and dealers attach value to the token beyond the underlying laboratory documentation; for stones with strong GIA, AGS, or Gübelin reports, the marginal value of an additional tokenised record has been a slow sell. The platform's longer-term significance probably depends on whether digital identity becomes a settled trade convention rather than an optional addition.
