Purple Rocks, Minerals & Gemstones
Found a purple rock and want a name for it? This guide lists all 32 purple rocks, minerals and gemstones in the StoneSnap database, from common finds like Amethyst, Fluorite, and Ametrine to collector specimens.
Color alone rarely identifies a specimen, so start with luster (25 glassy, 3 metallic, 2 dull or earthy, and 2 waxy, silky or pearly in this list), then check hardness with a scratch test and streak color. Each card links to a full identification guide with tests, look-alikes and value.

Frequently asked questions
What is a purple shiny rock most likely to be?
Shiny purple rocks are usually Amethyst, Fluorite, Ametrine, and Charoite. Check whether the shine is metallic or glassy, then test hardness against glass to narrow it further.
How do I identify a purple rock at home?
Rinse it, look at the luster and grain under good light, scratch it against glass and a steel knife to bracket its Mohs hardness, and rub it on unglazed porcelain to see the streak color. Compare the results with the purple candidates on this page, or scan it with the StoneSnap app for an instant match.
Are purple rocks valuable?
Most purple rocks are common and worth a few dollars as specimens, but gem-grade material such as Amethyst, Tanzanite, and Garnet can be worth far more. Each page lists a typical value range.
