Stone Shelf - Rock Identifier

Identify rocks, crystals, minerals, gemstones, and selected fossils from a photo, compare likely matches, and save every find in a personal specimen cabinet. Stone Shelf is built for rockhounds, mineral collectors, and curious explorers who want more than a one-off scanner result. Photograph a stone — from a beach pebble to a crystal or agate — and get likely matches with confidence context and lookalikes to rule out. Then keep the specimen with its photo, place, date, and notes. IDENTIFY WITH CONTEXT - Photo identification for rocks, minerals, crystals, gemstones, and selected fossils - Confidence level and alternate matches when a photo is ambiguous - Hardness (Mohs scale), luster, streak, and transparency - Similar specimens and practical ways to tell them apart - Physical verification checks using light, water, and everyday objects BUILD YOUR STONE CABINET - Save finds to a shelf organized by stone family - Give every specimen its own numbered field card - Keep the original photo, location, date, and field notes together - Edit, verify, or remove finds at any time LEARN IN THE FIELD - Guides for quartz, banded stones, and field journaling - Tips for beaches, riverbeds, roadcuts, and volcanic terrain - A searchable library of rocks, minerals, and gems STONE SHELF PRO Stone Shelf includes two free identifications each day.

Stone Shelf uses AI to suggest likely identifications. A photo cannot replace physical testing or expert examination. Always confirm significant, valuable, or safety-sensitive finds with a field guide, lab test, or qualified expert.
