Any Rock Identifier — Identify any rock or crystal from a photo, free to start
Any Rock Identifier names rocks, crystals, gems, minerals and fossils from a photo. Each result carries an honest confidence score and lists alternatives when a specimen is ambiguous, plus simple at-home tests — streak, hardness, magnetism, acid fizz — so an identification can be confirmed rather than taken on trust. A built-in field guide covers 130 stones, 10 look-alike guides and 7 how-to guides. The first 3 identifications are free; Pro unlocks unlimited IDs plus value and rarity estimates, real-or-fake authenticity checks, care guides and a downloadable report.
