Rock Identification Guide

To identify rock by picture, capture a clear photo of the crystal structure in natural light. A close, steady image helps the scanner compare color, texture, and pattern details.

Fracture patterns can be especially useful because many rock minerals have distinctive cleavage and crystal habits. If possible, include both the surface texture and a clean fracture view.

Color alone is not always reliable. Weathering, age, oxidation, lighting, and polishing can change how rock appears, so the best results come from combining cleavage, texture, hardness, and context.

Rock Identifier AI Scanner is designed to make this process faster for homeowners, geologists, gem collectors, and lapidary enthusiasts.
