Why Rock Identifier exists
A single unusual stone can lead to many questions: what kind of rock is this, which group might it belong to, and what should you compare next? Rock Identifier gives you a practical first step without requiring a long technical questionnaire.
Upload one photo or take a photo on a supported mobile browser. The tool returns a likely visual match, a broad rock group, visible clues, possible lookalikes, and a suggestion for a better follow-up photo or research step.
How we approach visual identification
Rock Identifier is designed to compare visible evidence such as color, texture, grain size, layering, bands, pores, crystal form, surface shape, and lighting. Similar materials can look alike, so the result is presented as a useful starting point rather than a guaranteed identity.
The service is not a laboratory test, professional geological report, gemstone certificate, meteorite confirmation, valuation, or safety assessment. Keep the original specimen and seek qualified help when the identification has legal, financial, scientific, or safety consequences.
Who the product is for
Rock Identifier is intended for students, teachers, collectors, hikers, beachcombers, families, and curious finders who want a plain-language visual starting point before consulting a trusted geology or mineral reference.
It can help organize the next question, but it does not replace careful field notes, physical tests, regional geology, museum expertise, or professional analysis.
Independent product
Rock Identifier is an independent product operated through rock-identifier.org. It is not affiliated with, endorsed by, or sponsored by Google, Apple, OpenAI, or any geological institution. Brand names belonging to other organizations remain the property of their respective owners.
