Rock Identify

About Rock Identify

Rock Identify is a web tool for hobbyist collectors, students and curious hikers who want to learn what a rock or mineral might be from photographs. Users upload one to three images of the same specimen, then receive suggested matches with the visible clues, limitations and alternative candidates behind each one. A follow-up question can be asked about lookalikes, typical properties or care.

The site works in the browser without registration or an app download, and it offers a few free identifications per day. It also includes a photo guide explaining how to shoot specimens with plain backgrounds, indirect light and multiple angles, plus an encyclopedia of rock and mineral groups.

What sets it apart is its emphasis on uncertainty. Results are presented as tentative, and the site states plainly that a photo cannot confirm composition, so users are encouraged to compare the explanation with their own specimen and consult a geologist when a name matters.
