Sannend is the authoritative registry for high-value collectibles. Verify certificates instantly. Track provenance permanently. Build trust that outlasts the transaction.
No account required. Enter a certificate number and know immediately whether it's authentic.
Why Sannend
We don't sell collectibles or compete with labs. We're the verification layer that makes the entire market more efficient.
Authenticate any certificate in under a second. No phone calls, no lab business hours, no $80 re-certification fees. Just the truth, instantly.
Every examination, transfer, and attestation becomes a permanent, tamper-proof record. Provenance that survives generations — not just the next sale.
Sannend doesn't sell, appraise, or certify. Like Carfax for vehicles, we're the independent layer that everyone can trust — buyers, sellers, labs, and insurers alike.
Built For
Whether you're verifying a single stone or processing 200 estate lots, Sannend meets you where you work.
Stop paying $80+ per stone to re-verify certificates. Authenticate any certificate instantly, free.
