AI Rock & Mineral Identification — Free Photo ID | Geo-Gem

Upload a photo and our AI identifies the rock or mineral, returning a name, category, confidence score, and links to the field guide entry.

How It Works

Take a clear photo of your specimen, upload it to Geo-Gem, and our AI model analyzes the color, texture, crystal structure, and other visual properties to identify it. Results include the rock or mineral name, geological category (igneous, sedimentary, metamorphic, mineral, gemstone, or fossil), a confidence score, and key physical properties such as hardness, luster, streak, and common locations.

Community Verification

After an AI identification, community members with geology expertise can confirm or correct the result. Expert-verified identifications are marked so you can trust the accuracy. You can also share your find as a community discovery, add a GPS location, and get feedback from fellow collectors.

Identification History & Journal

All your identifications are saved to your personal rock journal. Track what you've found, when, and where. Pro and Premium subscribers can upload up to five photos per identification for higher accuracy.
