ProvenzaAuthenticate an item

Prove it's real before you sell it.

Provenza gives your handbag, watch, or sneakers a verifiable authentication record — photographed, expert-reviewed, and permanently linked to a certificate buyers actually trust.

Human experts, not just AI guesses

Category specialists review your submission — stitching, hardware, serials, weight — and sign off personally. No black-box verdicts, just a name and a rationale you can read.

A certificate buyers respect

Each authenticated item gets a shareable digital certificate with photos, findings, and a scannable code — the thing that ends 'is this legit?' haggling for good.

48-hour turnaround

Snap the guided photos, ship if we need hands-on, and get your verdict in two business days. Most closet-clearing sellers finish a whole batch in a weekend.

Your permanent locker

Every piece you've authenticated lives in one place — receipts, care history, resale value estimates — so re-listing next season takes minutes, not archaeology.

Transfer it with the item

When you sell, the certificate transfers to the new owner in one tap. Provenance follows the piece, not your inbox, building real resale value over time.

Honest value estimates

See what comparable authenticated pieces actually resold for — grounded in real transactions, not wishful listing prices — so you price with confidence.

“I inherited three Cartier pieces and had no idea what was real. Provenza's watch specialist walked me through every finding. I sold two with certificates and got 40% more than my first offers.”
Marisol ReyesPrivate seller, Independent collector
“As a small consignment shop, I can't keep an in-house authenticator for every brand. Provenza's certificates are the reason my buyers stopped disputing and started repeat-purchasing.”
Daniel OkaforOwner, Second Story Luxe
“I flip sneakers on the side. Having a signed authentication record attached to each pair basically ended the fake accusations in my DMs. Worth every dollar of the flat fee.”
Priya VenkataramanReseller, Grail Room
