Stonebook
by Streetwise Software Online · SWSO
Identify rocks, minerals, gemstones, fossils and meteorites on your Mac, with no internet needed. Drop in a photo, answer a few guided questions about luster, hardness, streak and more, and Stonebook narrows it down from its 101-species library.
Guided identification
- Drop a photo, paste one, choose a file or use your Mac's camera
- Eight guided questions: color, luster, shape, scratch hardness, streak, weight, magnet and vinegar fizz
- A “Most helpful next” hint shows which test narrows it down fastest
- Honest about certainty: a photo alone is always called a “Rough guess”
