FAQ
How does Rock ID identify rocks?
Rock ID identifies rocks by matching your photo against a fixed, curated mineral and gemstone database. This ensures consistent results grounded in real mineralogical data, unlike apps that generate new answers each time.
What kind of information does Rock ID provide?
Rock ID provides the specimen's name, Mohs hardness, crystal system, chemical formula, color variations, typical locations, and an estimated value with a price range and rarity.
Does Rock ID guarantee 100% accurate identification?
No, Rock ID provides a confidence score on every result and a top-3 list of possible matches. It never claims 100% certainty, acknowledging the complexities of mineral identification.
