stilbite crystals with
Stilbite is a member of the zeolite family of silicate minerals. It is a hydrous
calcium-sodium aluminum silicate. Its most outstanding characteristic is a
strange crystal habit that resembles a sheath pinched in the middle. Stilbite
ranges from white to a pale pinkish orange color with a pearly luster.
