Gemsza
How We Review Listings
How listings are reviewed
Every lot on Gemsza is screened by an automated pipeline before it goes live: condition signals, AI-assisted price estimation against comparable sales, and a duplicate-listing check that flags re-lists and cross-account matches. Anything the system isn't confident about is held for a human reviewer rather than published automatically.
Category coverage
This review process runs across every category we list in — watches, fine art, jewelry, classic cars, coins, wine, rare books, collectibles, sports memorabilia, and antiques — so the same baseline of scrutiny applies no matter what you're bidding on.
Human review
Listings flagged by the automated checks, along with any buyer claim under our money-back guarantee, are reviewed by hand before a final decision is made.
