Usually found as a long, thin, prismatic or bladed crystal/s, with a pointed pyramid on top (clinopinacoidal), and very often embedded in a matrix. Fibrous masses, radiating sprays, and interlocking thin prismatic crystals are also common. May also be in reticulated masses and in grainy aggregates embedded in a matrix. Crystals are often striated lengthwise, and doubly terminated crystals are occasionally found.
