Rocco: Rock Identifier

Point your camera at a rock or mineral and Rocco tells you what it is — then helps you confirm it with the same tests geologists actually use.

Identify from multiple angles

• Guided capture: the whole specimen, a close-up of the surface, and a fresh break or cut face
• Rock class or mineral group, chemical formula, and crystal system
• Hardness on the Mohs scale, luster, streak color, and common colors
• Formation, common locations, and typical uses
• Estimated value range and hazard notes where relevant

Confirm it yourself with guided field tests

• A step-by-step Mohs hardness test using a fingernail, a copper coin, glass, and steel
• A guided streak test to read a mineral's true powder color
• Identification tips specific to what you found

Build a real collecting record

• Mark find sites on a map so you remember exactly where each specimen came from
• Save specimens to your collection or a wishlist, with a full scan history
• Ask Rocco's AI companion follow-up questions about any rock or mineral

Identification is based on visual AI analysis and may be inaccurate, especially for specimens that look similar but differ in composition. Hardness and streak tests can mark or damage a specimen — test on an inconspicuous spot, and skip testing anything you'd rather keep pristine.
