Selenite is one of the morphological varieties of the gypsum mineral.
The color of pure selenite is white - shown in the photo, but more often it is colored with impurities in yellowish, bluish or pinkish shades. It shines through perfectly. It is characterized by a silky shine and a beautiful iridescent optical effect of moving an iridescent light strip on a polished surface or a chip when turning a stone ("iridescence" or "cat's eye effect").
The effect occurs as a result of the scattering of light rays on thin, parallel surfaces of the boundaries of fibrous individuals. This effect occurs due to the parallel arrangement of numerous tightly fused thin fibers, is very pronounced in selenite, manifests itself only on surfaces parallel to the fibers. Selenite is much stronger than ordinary gypsum, because it does not have a very perfect cleavage characteristic of gypsum crystals, but it splits along the fibers perpendicular to the base of the unit.
