Listing is for (1 piece) Avg Size Range: (7 to 9 inches) Material Origin: (Morocco) Selenite, sometimes also called satin spar, is a variety of gypsum that tends to grow either in long fibrous or flat plate-like crystals, which can result in opaque or translucent pieces. An extremely soft mineral, selenite will often contain small inclusions of other minerals or internal cleaving where different crystal shapes meet. Please note: Selenite is a brittle mineral and will naturally degrade over time and with exposure to heat or moisture. Selenite can also naturally contain inclusions of other minerals, leading to red, brown, or even blue coloring in places and natural internal cleaving. These inclusions and cleaving do not affect selenite structurally in any way and are purely cosmetic.
