Quick answers about crystal identification
Crystal Identifier is a free web scanner that identifies crystals, gemstones, minerals, rocks, and fossils from photos using AI trained on verified specimens.
- How it works: Upload a clear photo in natural light; the AI reads color, crystal habit, luster, and transparency to suggest a mineral name and Mohs hardness.
- Best photo tips: Plain background, fill the frame, avoid glare, and include a fresh fracture or crystal face when possible.
- Accuracy limits: Strong for common minerals like quartz, calcite, and fluorite; tumbled stones and look-alikes may need hands-on testing.
- Mobile option: For saved collections and field use, many collectors also use the AI Rock ID iPhone app alongside the web scanner.
