Rock Identifier App - What Is This Rock?

Ruby Glint's rock identifier uses AI trained on thousands of rock and mineral specimens. Our identification accuracy exceeds 90% for common rocks and minerals. For best results, take clear, well-lit photos showing the rock's color, texture, crystal structure, and any unique characteristics. Multiple angles can help improve accuracy.

The Ruby Glint rock identifier can recognize over 6,000 types of rocks, minerals, crystals, and gemstones. This includes all major rock categories: igneous rocks (like granite, basalt, obsidian), sedimentary rocks (limestone, sandstone, shale), and metamorphic rocks (marble, slate, gneiss). It also identifies minerals (quartz, feldspar, calcite) and crystals of all types.
