Crystals are of prismatic behavior; tabular parallel to clinopinacoid; diamondshaped, with edges beveled by prism and pyramid faces. Other sorts uncommon. Twins frequent with the orthopinacoid the twin aircraft normally resulting in swallowtail twins. Cleavable huge; foliated; granular significant. Satin spar can be a fibrous gypsum with silky luster. Alabaster will be the wonderful-grained enormous selection. Selenite is a spread which yields broad colorless and transparent cleavage folia
