Mineral, Gem, Rock Identifier

Identify rocks with AI. See what others are discovering around the world. Tero is a rock identifier app for curious minds - whether you're on a hike, at the beach, or just found something interesting in your backyard. SCAN & IDENTIFY WITH AI Take a photo of any rock, mineral, gemstone, or fossil. Tero's on-device AI identifies it instantly - no internet needed. Get the top candidates with confidence levels, formation type, hardness, and more. NARROW IT DOWN WITH A QUIZ Not sure which candidate is right? Tero walks you through simple hands-on tests: scratch it with a coin, hold it to a flashlight, check if a magnet sticks. Each answer dynamically re-ranks the possibilities until you find your best match. EXPLORE GEOLOGY ON THE MAP Open the app and explore.
