Attach a verified grading record to each gemstone so buyer and seller settle from the same anchored certificate rather than dueling assessments. The original grading is bound to the specific stone's identity, so a dispute refers to the verified certificate instead of questioning its authenticity.
Turn a contested clarity and cut argument at the point of sale into settlement against one anchored certificate.
01.
Tie the grade to the gem. The Produce Grades and Certificates module anchors the original grading, clarity, color, and cut against the specific stone's identity, so the certificate cannot be swapped or reassigned.
02.
Freeze the assessment. The certificate is sealed by its digest, so any alteration to the recorded grade breaks the hash and is immediately detectable to either party.
03.
Prove it is the same stone. The Provenance Notary binds the certificate to the gem's identity, preventing a seller from presenting one stone's grading for another.
04.
Hold funds against agreement. Escrow and Conditional Settlement keep the purchase amount locked until both parties accept the anchored grade, so a dispute pauses payment rather than reversing it later.
05.
Refer to the original, not opinion. If the buyer's independent assessment differs, both sides refer to the verified original grading, resolving from a trusted record instead of two conflicting reports.
06.
Reduce disputes before they start. Because the grade is verifiable at the moment of sale, buyer and seller transact on shared evidence, cutting the frequency of quality disputes.
Follow a graded gemstone from certificate anchoring through an escrowed sale to an evidence-based resolution of a quality dispute.

Cerulea decomposes grading dispute resolution into modular contracts. Each layer anchors, escrows, disputes, and settles so that a quality disagreement is resolved against one trusted certificate bound to the stone.
Anchored grading is a horizontal capability across graded goods. Here is how different actors in gemstone trade put the shared certificate to work.
Anchor issued certificates to specific stones so their grades cannot be forged or reassigned, protecting lab reputation and giving the market a trusted reference at the point of sale.
Key Asset Types
Transact against one verified grade with funds held in escrow, resolving any clarity or cut dispute from the anchored certificate instead of costly re-grading and lost sales.
Key Asset Types
Settle grading disputes on evidence rather than opinion, referring both parties to the immutable original certificate and clearing contested trades quickly.
Key Asset Types
Whether you are bridging a grading lab's system or capturing sales from a dealer's wallet, Cerulea routes both into one anchored grading record.
For laboratories and exchanges on legacy systems. Existing certificates are translated into signed, stone-bound on-chain records through the API gateway automatically.

The legacy timeline reflects graded-goods marketplace benchmarks. Building custom certificate anchoring, escrowed settlement, and an evidence-based dispute flow for an average marketplace takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your grading and settlement rules into pre-audited WebAssembly binaries and provisions the ledger and escrow layer instantly.
