Photo matches can be wrong, and details may be incomplete; missing risk information does not mean safe. Do not use the app to decide whether anything can be eaten or safely handled. Verify important identifications independently and follow local rules. A photo is not a laboratory test and cannot certify a specimen as natural, untreated or genuine. Hardness information describes reference properties, not a measurement of your specimen; mineral information and cultural stories are not health or therapeutic advice.
