Scolecite is a hydrous calcium aluminum silicate, a zeolite mineral with a hardness of 5 to 5.5. Its crystal system is monoclinic. It occurs as thin, vertically striated prismatic crystals, and in radiating fibrous masses. It can be colorless, white, or yellowish, and it has a vitreous to silky luster. Scolecite forms in cavities in basaltic lavas, as well as cavities in syenites and granites.
