Fibrous gypsum, a variety of the mineral gypsum (CaSO42H2O), displays a chatoyant, silky sheen resulting from the alignment of its fibrous crystals. This optical phenomenon, reminiscent of polished satin fabric, distinguishes this variety from other forms of gypsum. A common example is its use in decorative objects and carvings.
The unique optical characteristics of this mineral variety contribute to its value as an ornamental material. Historically, it has been utilized for carvings, jewelry, and decorative elements due to its workability and attractive luster. Its softness, while limiting its use in certain applications, facilitates intricate carving and shaping, enabling artisans to create detailed works of art.
