Authentication

For private sales, you can add an authenticity check for CHF 40 at checkout. We'll then inspect the piece before it reaches you. Professional dealers guarantee the authenticity of their items themselves.

The authenticity check and VaultBase's other services are currently only available for sellers in Switzerland and for delivery within Switzerland. Certified partners and services that sellers offer themselves are not affected.

Step 1

Inspection

Certified gemmologists examine material, hallmarks, gemstones, and craftsmanship using specialist equipment.

Step 2

Documentation

Every detail is documented and cross-checked against the seller's description.

Step 3

Preparation

Before shipping, the piece is professionally cleaned and gently refurbished.

Step 4

Certificate

You receive a digital authenticity certificate with every purchase, your assurance in writing.

Verified or your money back

If a piece fails the authenticity check or differs from its description, you get a full refund. The seller is only paid out once the check is passed or you confirm receipt.
