We have been importing different kinds of Selenites for many years now. There are three main types of Selenite, Moroccan Satin Spur, American Selenite Windows, and Selenite that grows in Geodes, principally from Brazil and Uruguay.
This translucent or transparent material is a type of gypsum, a very common mineral. It is named after the god of the Moon, Selene, as it can almost glow.
We have examples of all of them. Please ask what we have in stock. We have used this material for table tops, please see here. Click here for more information on Selenite
