Selenite massive.
Selenite is a variety of the mineral gypsum in the form of transparent crystals or crystalline masses.
Its name derives from Selene, the Greek goddess of the Moon, due to the type of reflection, which gives it a pearly glow similar to moonlight.
It is used for making lamps and obtaining plaster.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
