Rock Identifier: Complete Guide
The AI Rock Identifier uses advanced computer vision to identify rocks, minerals, crystals and fossils in real time. Point your camera at any specimen to get an instant identification with its rock class, Mohs hardness, likely mineral composition, lustre, streak and rarity — all without uploading a photo or creating an account. Whether you're out fossicking, hiking, at the beach, or sorting a collection at home, the scanner tells you what you're holding in seconds.

Why Use Rock Identifier?
Instant Identification
Every specimen gets a most-likely identification with a confidence score, so you know what you found and how certain the match is.
Geological Properties
See the rock class (igneous, sedimentary, metamorphic, mineral or fossil), estimated Mohs hardness, lustre, texture and streak in one place.
Mineral Composition
Get the likely minerals present in the specimen — quartz, feldspar, mica, calcite and more — plus how it probably formed.
Multiple Specimens at Once
Scan a pile or a tray and the scanner identifies every visible specimen, highlighting the best match so you can compare them side by side.
100% Free & Private
No account, no upload, no tracking. The scanner runs in your browser — your photos never leave your device unless you choose to save them to your scan history.
Tips & Best Practices
- ›Clean the specimen and photograph it dry — mud and moisture hide the texture and grain.
- ›Natural daylight gives the most accurate colour and lustre readings.
- ›Hold your phone steady and let the specimen fill most of the camera frame.
- ›Take a second photo of any fresh broken surface, which often reveals the true internal structure.
