StoneLedger

StoneLedger is a mobile + web app for pre-owned and vintage jewelry that standardizes verification and listing quality for small dealers and serious buyers. Sellers create a “listing dossier” by capturing guided photos/video, measurements, weight, hallmarks, and any lab reports. The app then runs AI-assisted checks for common red flags (mismatched hallmarks, inconsistent stone sizes, suspicious setting wear patterns) and produces a shareable dossier link for marketplaces, Instagram sales, or in-store clients. Buyers can request an independent verification workflow: the seller ships to a partnered local jeweler/appraiser for a quick inspection, and the verified result is appended to the dossier. This is not a magic authenticity detector; it’s a structured process that reduces uncertainty, returns, and disputes. Monetization: per-verification fees, dealer subscriptions, and optional escrow/insured shipping add-ons.
