Colemanite Ca2Bc031+5H20 Colemanite is a hydrous borate of calcium often occurring in monoclinic crystals, short prismatic in habit, and somewhat resembling those of datolite, also in cleavable to granular and compact masses. Colemanite is commonly white or colorless and of a vitreous to dull luster. Under this species are included: Priceite. A massive variety, white and chalky in appearance and loosely compacted in structure. Pandermite.
