🔎 Crystal Identifier

Got a mystery stone? Pick what you can observe, and Crystopedia ranks the likely matches. It covers 321 popular crystals and gems with full data, plus about 1,245 other minerals with recorded properties.

This is a rough guide, not a definitive ID. Many minerals look alike, and dyed, heat-treated or fake stones are common. For certainty, ask a gemologist or a local rock club. Never taste-test minerals, and handle acid with care.
