Although the name Selenite means "moonstone", after the moon Goddess, Selene, it has no relation to the magickal Moonstone. Selenite is a clear form of gypsum and often forms when seawater evaporates, but oddly enough, it can be damaged if exposed to or immersed in water. This is why water cleansing is not advised, nor is
The use of whole gypsum plasters, i.e. made of gypsum binder and coarse selenite aggregate, still can be found in several historic buildings in Italy (both monumental and rural), but it is absent in historical architectural treatises and totally neglected in current restoration works. The main features of these plasters include good mechanical properties and good resistance, even to outdoor ...
Gypsum is an industrially important mineral. It is the primary ingredient of plaster-of-Paris, which is finely ground Gypsum, and it is used in the production of cement. It is also the main component of sheet rock. It is used as a flux for creating earthenware, and can be used as a fertilizer.
As nouns the difference between gypsum and selenite is that gypsum is a mineral consisting of the hydrated calcium sulphate when calcined, it forms plaster of paris while selenite is (mineralogy) a soft, glassy form of gypsum (chemical formula ca]]so 4 ·2[[water|h 2 o).
Selenite is an alternate name for the mineral Gypsum. The word Selenite comes from the Greek "selenites", meaning "moon stone" or "moon rock", with the root word "Selene" meaning "Moon", and for good reason - the mineral Selenite is the near transparent and colourless crystal form of Gypsum that exudes a pearly luster which glows and can very much resemble the moon.
Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemi-hydrate (CaSO 4.1⁄2H 2O) – with three quarters of the water removed. Gypsum hemi-hydrate is also known as Plaster of Paris. Prolonged heating over several hours results in the formation of
The crystal structure of selenite gypsum from Valea Rea (Buzau County, Romania) has been refined to Rwp and GOF indices of 2.062 and 1.10%, respectively, using X-Ray powder diffraction data and the Rietveld method. The Rietveld refinements were

Selenite Gypsum is a pure, white, soft stone and is considered a mineral or a specimen rather than a crystal. In Brazil, it comes out of a flowering Amethyst geode, either attached or formed inside the geode. Once separated, the Selenite Gypsum radiates beautiful light. When Selenite shows color, it denotes the presence of other minerals like ...

A variety of Gypsum The name 'selenite' is mostly synonymous with gypsum but has been used historically to describe the transparent variety, as opposed to satin spar gypsum for the fibrous variety and alabaster for the fine-grained massive form. The original name was given by J.G. Wallerius in his 1747 book "Mineralogia, eller Mineralriket" (p.50), as 'selenites'.
Gypsum and Selenite have the same chemical composition but differ in crystallisation habit. Selenite is usually crystalline and the association of the impurities is superficial which are eliminated by washing. Gypsum is fine grained in nature and is beneficiated by flotation only. Both the minerals find extensive use in the ferti-lizer industry and a minor quantity in the manufacture of ...
Gypsum is a very common mineral; only a select few of the best and most classic are mentioned here. The finest European localities are Lubin, Poland; Kapnick, Maramures Co., Romania; and the Sulfur mines of Agrigento Province, Sicily, Italy. Desert Roses and Sand Gypsum come from several places in the Sahara Desert in Algeria and Morocco. Excellent Gypsum specimens have come from China at ...

03-07-2021· Selenite is actually a crystallized form of gypsum that can be found in caves and mines. In actuality, the largest crystal ever discovered in the world was made out of selenite! Selenite and gypsum share a common material with only their chemical formulas being different.
Selenite Hardness: 1.5 - 2 Gemological Properties: Selenite is hydrous calcium sulfate mineral; a form of gypsum crystal also known as Satin Spur and in fine grain form Alabaster. Selenite is named after the Greek goddess of the moon, Selene because of its soft white light and …
rock known as alabaster. Another type, selenite, is a transparent crystalline material that forms large, well-developed crystals. Aggregates of fibrous gypsum form a variety called satin spar. Although associated with gypsum, anhydrite lacks H 2O molecules. Anhydrite closely resembles gypsum in hand
