This app is a game-changer for rock hounding! It’s incredibly easy to use out in the field—I just snap a quick photo, and it instantly gives me all the details I need. The estimated stone value feature is the ultimate bonus. Highly recommend!

Incorrect Identification. Misidentified three crystals. Larvakite it identified as elaborate, nuummite was identified as onyx and my elaborate was identified as fake.
