AI Rock Identifier

How to Use This Free AI Rock Identifier

Upload a photo of your rock or describe it in the text box. The AI analyzes color, texture, crystal structure, and patterns to identify your specimen. You'll get the scientific name, geological classification, and interesting facts instantly.

For best results, take photos in natural daylight with a plain background. Include close-ups of unique features like crystals or layers. When describing, mention color, weight, hardness, and where you found it.

Why Use an AI Rock Identifier?

Identifying rocks accurately requires extensive geological knowledge. This AI rock identifier gives you expert-level identification instantly without years of training. Perfect for rockhounds, geology students, hikers, and anyone curious about the stones they find.

Students verify homework identifications and learn to recognize rock types faster than textbooks alone. Hikers identify interesting finds from trails and beaches. Collectors build accurate mineral collections with proper scientific names instead of guessing.

Best AI Rock Identifier Features

Our free AI rock identifier provides instant results with zero barriers. No sign-up required, completely free unlimited use, and simple upload or description interface. The AI recognizes igneous, sedimentary, and metamorphic rocks, plus common minerals, gems, and semi-precious stones.

Each identification includes scientific name, common name, geological category, formation process, typical locations, and interesting facts. This educational approach helps you learn geology while identifying specimens.

What Rocks Can This Identify?

The AI identifies all three main rock categories: Igneous (granite, basalt, obsidian, pumice), Sedimentary (limestone, sandstone, shale), and Metamorphic (marble, slate, quartzite, gneiss).

It also recognizes common minerals like quartz varieties (amethyst, citrine, rose quartz), semi-precious stones (jade, turquoise, opal), and metallic minerals (pyrite, hematite, magnetite).

Tips for Accurate Identification

Take photos in bright natural daylight with a plain white background. Show multiple angles including any broken surfaces that reveal internal structure. Close-ups of crystals, layers, or patterns improve accuracy.

Include where you found the rock—geological context helps since beach finds differ from mountain rocks. Test hardness if possible: can you scratch it with a fingernail, penny, or steel knife? Note if it feels unusually heavy or light for its size.

Frequently Asked Questions

Is this AI rock identifier free? Yes, completely free with unlimited use and no sign-up required.

Can I upload photos from my phone? Yes, upload directly from your phone or camera. Works on all devices.

How accurate is AI rock identification? Very accurate for common rocks and minerals. For rare or valuable specimens, use this as a first step then seek professional verification.

Do I need to describe AND upload a photo? No, either one works. But combining both gives the most accurate results.

What if I found something valuable? The AI identifies common specimens reliably. For gems, meteorites, or rare minerals, consult certified gemologists or geologists for professional verification.

Can students use this for geology homework? Absolutely. Great for learning to recognize rock types and verifying identifications.
