Fluorescent Minerals & UV-Reactive Crystals

Mangano Calcite - Raven's Cauldron

Discover the hidden glow of fluorescent minerals and UV-reactive crystals—from fiery orange Yooperlite and pink Mangano Calcite to ruby-bearing stones, blue amber and lab-created Honeycomb Ruby carvings. Choose a pocket stone, polished carving or display specimen for your collection, altar or meditation space.

Bring out the glow: UV light is needed to see fluorescence. Yooperlite is commonly viewed with a 365nm longwave UV light; some of our Mangano Calcite photographs were taken under shortwave UV. Color and brightness depend on the specimen and light used. Check each listing’s photos and material or size options before choosing.
