Gemstone Provenance Engine

Track every stone.
Prove it conflict-free.

Track each diamond from mine to consumer through cutting and trading, replacing counterfeitable paper Kimberley Process certificates with a tamper-proof digital record. The buyer receives an NFT certificate that proves conflict-free origin and transfers with the stone on resale.

The Foundation

The Execution Mechanics

Turn a forgeable paper certificate into a stone-level record that survives cutting, trading, and resale.

01.

Stone-Level Identity

Give every rough its own record. The Traceability Ledger mints a unique identity for each stone at the mine, so provenance is tracked per gem rather than per shipment as paper certificates do.

02.

Transformation Linking

Follow the stone through the saw. When a rough is cut and polished, the Provenance Notary links the resulting stones to their parent, preserving the chain across the pipeline's physical transformations.

03.

Conflict-Free Attestation

Anchor the Kimberley claim. Each custody step carries a signed conflict-free attestation, so origin from a certified mine rests on cryptographic evidence rather than an easily copied paper form.

04.

Verifiable Trader Identity

Bind actors to credentials. The DID and VC Ledger gives miners, cutters, and traders verifiable identities, so every handoff is signed by a known, credentialed party.

05.

Consumer NFT Certificate

Hand the buyer proof. At retail the record resolves to a tamper-proof NFT certificate that names the specific conflict-free mine of origin and travels with the stone.

06.

Resale Transfer

Keep provenance with the gem. On resale the NFT certificate transfers to the new owner alongside the ring, so a second-hand stone carries the same verifiable origin as when it was first sold.

The Provenance Lifecycle

Follow a single diamond from a certified mine through cutting and trading to a consumer whose NFT certificate transfers on resale.

Smart Contract Anatomy

Cerulea decomposes gemstone provenance into modular contracts. Each layer registers, transforms, credentials, and certifies a stone so that conflict-free origin survives every step from mine to consumer resale.

Applicability Across the Spectrum

Stone-level provenance is a horizontal capability across high-value minerals. Here is how different actors in the gemstone pipeline put the shared ledger to work.

Mines & Kimberley Bodies

Replace forgeable paper certificates with a per-stone digital origin record, letting certification bodies confirm conflict-free provenance cryptographically instead of inspecting easily counterfeited forms.

  3. 3Kimberley Records

Cutters & Traders

Move stones through cutting and trading with credentialed, co-signed handoffs, preserving provenance across transformation and proving a clean chain of custody to buyers downstream.

  3. 3Trader Credentials

Retail & Consumers

Hand buyers a tamper-proof NFT certificate naming the specific conflict-free mine, turning verified origin into a trust signal that transfers with the stone on resale.

Network & Execution Architecture

Whether you are bridging a certification body's registry or capturing custody from a trader's mobile wallet, Cerulea routes both into one stone-level provenance record.

Track A: Certification Body Bridging

For Kimberley Process bodies and grading labs on legacy systems. Existing origin certificates are translated into signed on-chain stone identities through the API gateway automatically.

Track B: Trader & Consumer Execution

For cutters, traders, and retail on mobile. Custody handoffs and consumer certificate issuance are signed directly from wallets and routed to the ledger.

Technical Methodology

The legacy timeline reflects luxury supply-chain integration benchmarks. Building custom per-stone tracking, transformation linking across cutting, verifiable trader identities, and a consumer NFT certificate layer for an average pipeline takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your provenance and identity rules into pre-audited WebAssembly binaries and provisions the ledger and certificate layer instantly.
