Point it at any rock, mineral, crystal, gemstone, fossil or meteorite, and this rock identifier returns a full identification in seconds: the name, real geology data, and an estimated value range for the rock in your photo. WHAT YOU GET IN EVERY ROCK SCAN \- Rock or mineral species name, with the chemical composition formula \- A confidence rating (high, medium or low), so you know how certain the ID is \- An estimated value range for the stone in your photo \- Mohs hardness, color, luster and streak \- Category: igneous, sedimentary, metamorphic, mineral, gemstone, fossil or meteorite \- Formation: how that rock actually forms underground \- Typical locations worldwide where the mineral is found \- Identifying features that separate the rock from common look-alikes \- Common uses, plus a fun fact for every specimen ESTIMATED ROCK VALUE ON EVERY RESULT Most rock identifier apps stop at the name. Rock Identifier adds a typical market range for the stone you photographed, so a trail find or a shop purchase comes with context. Values are estimates for guidance, never appraisals or certifications. REAL GEOLOGY DATA, NOT A ONE-LINE LABEL This rock identifier reports what a rockhound actually wants: Mohs hardness, chemical composition, streak, luster and formation history. Learn why an igneous rock differs from a sedimentary or metamorphic rock, and how to tell quartz from calcite in the field. ONE APP INSTEAD OF FIVE Rock Identifier doubles as a rock scanner, stone identifier, crystal identifier, mineral identifier, gemstone identifier and fossil identifier. One photo, one result screen, every category covered. WHAT ROCK IDENTIFIER RECOGNIZES \- Rocks: granite, basalt, obsidian, limestone, sandstone, slate, marble \- Minerals: quartz, pyrite, mica, feldspar, calcite, fluorite, malachite \- Crystals, gems and gemstones: amethyst, agate, jasper, opal, turquoise, garnet \- Geode, druzy and raw crystal cluster specimens \- Fossils, ammonites and petrified wood \- Suspected meteorites, ores and tumbled stones ASK AI ABOUT YOUR ROCK Ask follow-up questions in plain language, anchored to the exact rock you scanned. How do I clean this stone? Is it worth tumbling? What separates it from its look-alike? YOUR ROCK COLLECTION, ORGANIZED Every rock scan is saved on your device with the photo, name, date and estimated value. Your rock collection becomes a searchable inventory you can browse and share. WHO THIS ROCK IDENTIFIER IS FOR \- Rockhounds and collectors identifying trail, beach and creek finds \- Families answering "what is this rock my kid found?" \- Crystal and gemstone buyers checking a stone before or after a purchase \- Earth science students and teachers learning hardness, composition and formation \- Anyone who has pocketed a rock and wondered what it is HONEST LIMITATIONS \- Rock Identifier needs internet. The rock scanner runs on a server, so there is no offline mode. \- This is an AI identification, not a laboratory assay, an appraisal or a certification. \- Value figures are estimated typical market ranges, not resale guarantees. \- The confidence rating flags ambiguous rocks. Weathered or wet surfaces are harder to identify, so clean, well-lit photos work best. \- The app interface is available in 33 languages, English included.
