Common questions
No. Photo-based results are informed estimates. Similar minerals can require physical, optical, or laboratory testing for definitive identification. Do not rely on the app for safety-critical decisions or professional appraisal.
The app provides an indicative range based on the likely mineral type and general specimen characteristics. Actual value can vary significantly with weight, quality, treatment, provenance, local demand, and professional grading.
Your scan history, collection, custom prices, saved scan images, and finding locations are stored locally on your device. They may also be included in your device backup depending on your Apple backup settings.
A mineral must be in your collection and have a saved finding location. Open its detail page, choose Location, and use your current position or search for a place manually.
Open iOS Settings, tap your Apple ID, choose Subscriptions, and select Rock Identifier & Gem Scanner. Billing and cancellation are managed securely by Apple.
