Colour:Colourless, light tints ...
Name:From the Greek σελήυη, for "moon," in allusion to the moon-like white reflections of the mineral or to the quality of the light transmitted by semi-pellucid gypsum slabs of cleavages used as windows.
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'. Named from the greek 'σεληνη' (the moon), probably from its pale bluish reflections.
