Selenite is a form of Gypsum. Gypsum forms when salt water evaporates. The evaporation of ocean brine forms extensive beds of Gypsum with similarly formed Anhydrite (also known as Angelite) and Halite (a form of crystallized table salt). Gypsum forms all over the world wherever there is salt water, deserts, tunnels, new formations in old mines.
Gypsum is an evaporite, so it evaporates out of water and then it crystallizes. Gypsum is the first mineral to separate from evaporated sea water because of its low solubility (its capability of being dissolved). Then it crystallizes and blows into sand dunes. White Sands, New Mexico has 225 square miles of white Gypsum sand blown up to 60 feet high sand dunes. The Cave of Swords in Naica Mexico has Selenite crystals growing 6 feet long and more!
Types of Selenite
White Selenite is the crystalline version, transparent, colorless with a pearly luster. Selenite has many thing layers with square shapes which are easily peeled. White Selenite is used to protect the aura from outside influences. It is often used for cell regeneration and is beneficial in balancing all of the chakras.
Orange Selenite, also known as Peach or Red Selenite, has been colored by other minerals for its light to dark pearly orange color.Orange Selenite holds the same energies as Selenite with the added energy to balance the Sacral Chakra.
Fishtail is a twinned crystal (a crystal that has two parts growing like a mirror).
Satin Spar is the striated compact and fibrous form.
Desert Rose forms in the desert with Quartz and sand and looks like a brown sandy flower. Desert Rose is used to connect with Earth elements and manifest what you want to occur in the physical world. Use Desert Rose at the Third Eye Chakra.
Alabaster is the fine grained massive stone which is translucent white. When Alabaster is heated it looks like marble. It is also often dyed. Alabaster has been popularly used to carve ornaments of all kinds.
Streak Color: (can vary from surface color, this is the color of the crystals’ powdered minerals): White
Group: Calcium Sulfate (Sulfates commonly form in evaporitic environments)
Cleavage (where the crystal breaks off naturally to form a new face, parallel to its structure. This is a clean break and can cleave over and over again along the same face, retaining the crystals structure): Good in one direction, poor in another
Fracture (where you break the crystal not on a natural cleavage): Subconchoidal (Not as curved as Conchoidal. Conchoidal is a clam-like fracture which looks like broken glass) to Uneven/Brittle
Luster: Vitreous (glassy) to Pearly
Tenacity: Brittle (little resistance to breakage)
Transparency: Transparent (light flows through crystal) to Translucent (allows light through the crystal but not fully transparent)
