About Rock & Mineral Identification

Spotter identifies rocks, minerals, crystals, and gemstones from a photo, with detail on how they form and where they occur. Whether you picked it up on a hike, a beach, or a riverbed, point your camera and get a starting identification in seconds.

Each result covers the specimen name, its properties, and geographic occurrence. For anything of real value, a jeweler or gemologist should confirm — Spotter is a fast, reliable first identification and learning tool.

Tips for Better Identification

Shoot in good, even light and get close enough to show texture and any crystals.
Photograph a freshly broken or clean surface when possible.
Note the color, luster, and whether it feels unusually heavy.
Where you found it (riverbed, volcanic area, limestone region) is a strong clue.
