Clear & Colorless Rocks, Crystals and Minerals

Found a clear or colorless crystal? 54 entries in the StoneSnap database can appear transparent or colorless, from everyday Clear Quartz, Selenite, and Calcite to rarer finds. Colorless stones are separated by hardness, luster and how they break, not by color.

Color alone rarely identifies a specimen, so start with luster (52 glassy, 1 dull or earthy, and 1 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 clear shiny rock most likely to be?

Shiny clear rocks are usually Clear Quartz, Selenite, Calcite, and Rock Salt. Check whether the shine is metallic or glassy, then test hardness against glass to narrow it further.

How do I identify a clear 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 clear candidates on this page, or scan it with the StoneSnap app for an instant match.

Are clear rocks valuable?

Most clear rocks are common and worth a few dollars as specimens, but gem-grade material such as Diamond, Topaz, and Zircon can be worth far more. Each page lists a typical value range.
