Why Sannend

Infrastructure for trust

We don't sell collectibles or compete with labs. We're the verification layer that makes the entire market more efficient.

Instant Verification

Authenticate any certificate in under a second. No phone calls, no lab business hours, no $80 re-certification fees. Just the truth, instantly.

Permanent Provenance

Every examination, transfer, and attestation becomes a permanent, tamper-proof record. Provenance that survives generations — not just the next sale.

Neutral Registry

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.

Whether you're verifying a single stone or processing 200 estate lots, Sannend meets you where you work.
