StoneChain

StoneChain is a web + mobile AI-assisted provenance and custody app for high jewelry pieces, built for brands, ateliers, and high-end resellers who need defensible documentation. It creates a “digital dossier” per piece: stone certificates, workshop steps, repair history, high-res macro photos, chain-of-custody transfers, and insured shipping events. The AI helps standardize messy documents (labs, invoices, appraisals) into a consistent record, flags missing fields, and detects photo mismatches over time (e.g., prong wear, stone swaps) using image comparison. Each transfer generates a signed handover receipt and optional customer-facing QR view that reveals only approved details. This is not a consumer marketplace; it’s compliance-grade ops software that reduces disputes, accelerates resale, and makes insurers and buyers more comfortable with seven-figure items.
