StoneScout: Rock Identifier

Identify rocks, crystals, and minerals from a photo—without pretending every photo has one certain answer.

StoneScout gives you ranked possible matches and suggests safe observations that can separate lookalikes. Add hardness, streak, luster, magnetism, transparency, or crystal form to refine the ranking.

IDENTIFY WITH MORE CONTEXT

1. Take a photo, or choose one you already shot in the field.
2. Compare likely candidates and see how they rank.
3. Review simple confirmation tips, or add physical traits and re-check.

EVERY SCAN INCLUDES • A ranked shortlist instead of one unexplained guess • Relative confidence for each candidate • Safe observations that can help separate close lookalikes • Scan history you can revisit later

SAVED REFERENCE CARDS INCLUDE • Expected physical properties, including Mohs hardness, crystal system, luster, streak, transparency, fracture, and color variations • Reference chemistry, including classification, formula, and constituent elements • Formation and typical locality information • Common imitation clues and general value context—not authentication or an appraisal • Care, handling, and health-and-safety notes • Traditional crystal meanings, clearly labeled as lore rather than science

YOUR POCKET MUSEUM • Save finds to a searchable collection with custom titles and field notes • Add multiple photos per specimen, with captions and a primary image • Keep a wishlist of stones you are still hunting for • Optionally tag where a find came from • Share a specimen card with friends • Your saved collection stays on your device

BUILT-IN FIELD GUIDE Browse an illustrated reference library covering quartz, chalcedony and jasper, carbonates and sulfates, feldspars and micas, silicate minerals, ore and metallic minerals, gems and jewelry stones, and common rocks.

HONEST ABOUT UNCERTAINTY Many specimens cannot be identified conclusively from a photograph. StoneScout gives you a ranked educational starting point and useful next steps. It is not a substitute for laboratory testing, professional appraisal, authentication, or safety advice. Consult an expert when the answer has financial, legal, historical, or safety consequences.
