The story
behind the app.
Rock Mineral ID is the home of Gem & Rock Identifier: Scan for iPhone and Rock & Mineral Identifier AI for Android, developed by İlker Beri. The app brings photo-based identification, geological information, and a personal specimen collection into one place.
The app is for the stone you find on a walk, the crystal you have always wondered about, and the collection you are slowly building. It is free to download and offers in-app purchases. Current access, prices, and subscription terms are shown in the App Store or Google Play and the app.
How to use an identification
AI can suggest what a specimen might be from a photograph. Treat that suggestion as a starting point and compare it with the specimen’s observable properties. Similar-looking minerals, altered surfaces, and synthetic or treated stones can be difficult to distinguish.
For authenticity, financial value, or an important identification, consult a qualified geologist, gemologist, or suitable laboratory. The app does not issue gem certificates or professional appraisals. The USGS explains the limits of identifying rocks from photographs.
About the field notes
Our field notes are prepared with AI assistance for this site and published by İlker Beri, the app developer. They introduce practical observations and link to primary geology and gemology references. They have not been independently reviewed by a geologist. Each guide identifies its publisher, publication date, and sources so you can follow the evidence.
