Gypsum is a common sulfate mineral that forms as colorless to white crystals and masses, often displaying a silky to pearly luster. It occurs in a variety of habits, including tabular crystals, fibrous masses, and translucent to transparent sheets in alabaster and satin spar forms. Dependent on setting, gypsum can be found in evaporite environments and hydrothermal veins, with notable specimens emerging from decomposed sedimentary rocks and evaporitic beds. High-quality crystals from classic localities exhibit sharp termination and lustrous faces, while alabaster shows smooth, opaque to translucent sculpted forms ideal for carvings and display.
