Assay-KO

Assay is a public App Store tool for jewelry identification and a reference valuation range, based on photographs and notes you submit. Anyone may purchase and use it — no invitation and no company account. Submit clear images of the piece, hallmarks, and any existing paperwork. Add an optional short video and notes. Track your submissions on this device. When you need a formal report from an internationally recognized laboratory, Assay guides an offline mail-in process. Laboratory fees, shipping, and handling are settled outside the app — never as an in-app purchase. Assay does not sell jewelry, run auctions, or offer consignment. Important: opinions inside Assay are preliminary and for reference only. They are not certified laboratory reports or insurance appraisals.
