Several varieties of gypsum are used as decorative stones. The most important, alabaster, is found as fine-grained masses in pastel shades, but is commonly stained in stronger colors.
Selenite is colorless, occasionally cut for collectors, but very soft. Satin spar is a fibrous variety, polished or cut in cabochon. Rose shapes (called “desert rose”) also occur. Gypsum also comes in cat’s eye effect.
Localities include Italy and England (Alabaster); Italy, Mexico, United States and Chile (Selenite).
