The color of Orange or Red Selenite (as with other color variations of the crystal) is caused by the inclusion of minerals. Different minerals will result in different colors and color intensity. Here are some properties of Red Selenite: Red Selenite is sometimes referred to as Red Satin Spar Selenite.
Gypsum and Halite: Evaporite Minerals Gypsum is readily identified by its softness (a fingernail scratches it). Gypsum comes as clear crystals that display one perfect cleavage (selenite), as blocks of featureless white rock (alabaster), and as silky fibrous blocks (satin spar).Halite (next page) breaks into cubes (three cleavages at right angles) and tastes like table salt. Go to Halite page.lear crystals or crystal fragments of gypsum are called selenite. These are four more cleavage fragments of selenite. The good cleavage is again parallel to the ground surface. There are also two poor cleavages that can be seen in three of the four samples shown here.
