How to Identify RocksLike a Pro
Whether you're a curious hiker, a budding geologist, or someone who just found a cool-looking stone, here's how rock identification actually works.
🎨 Look at the Color & Luster
Color is the first thing you notice, but it can be tricky. Many rocks share similar colors. Luster (how light reflects off the surface) helps narrow it down. Is it glassy? Dull? Metallic?
🔍 Check the Texture
Is it smooth or rough? Can you see individual grains? Fine-grained rocks like basalt cooled quickly, while coarse-grained rocks like granite formed deep underground over millions of years.
💎 Test the Hardness
The Mohs hardness scale goes from 1 (talc) to 10 (diamond). A rock that scratches glass is harder than 5.5, a helpful clue for rock identification.
📱 Or Just Use AI
Don't have a geology degree? No worries. Rock Identifier analyzes color, texture, crystal structure, and hundreds of other features in seconds. Just point your camera and let AI do the heavy lifting.
