CrystalScanner is a free AI-powered identification platform for crystals, gemstones, minerals, and precious metals. Users upload 1–3 photos of any specimen and receive a detailed identification result in seconds — including the mineral name, scientific name, confidence percentage, crystal system, Mohs hardness, luster type, formation details, rarity rating, collector value, global locations, similar minerals, and practical collection tips.

The platform covers 26+ specialist identification tools including Crystal Identifier, Diamond Identifier, Gemstone Identifier, Gold Identifier, Sapphire Identifier, Ruby Identifier, Pearl Identifier, Mineral Identifier, and more. Each tool uses a dedicated AI system prompt engineered for its specific domain — providing gemologist-level reasoning for gems, crystallographer-level analysis for crystals, and geologist-level assessment for rocks and minerals.

CrystalScanner is built for rockhounds, gem collectors, jewellery owners, geology students, prospectors, and anyone who has ever found an unknown stone and wanted to know what it is. The platform requires no sign-up, no app download, and no payment. Available in 21 languages.
