StoneSort: Rock & Crystal ID
Identify gems, minerals, rocks
Found a rock on a walk or at the beach? Take a photo. StoneSort shows its best 3 guesses, in plain words.
How it works
- Take a photo of the rock or crystal.
- See 3 guesses. Each one says "Very likely", "Maybe" or "Long shot". If we are not sure, we say so.
- Check it yourself. Answer 3 quick questions: does it scratch glass, what color line does it leave on a tile, and where did you find it. The list re-sorts.
Fair prices
Your first 3 scans are free. No card needed.
After that: $2.99 a week or $24.99 a year. No hidden trial. Cancel any time in one tap, in the app's Settings.
Your photos stay private
We remove location data from your photo, on your phone and again on our server. We never keep your photo. Read the privacy policy.
StoneSort is for learning and fun. It is not an expert inspection.
