Raw natural ulexite.
Ulexite is usually found in rounded aggregates, forming white masses with a silky luster. It can also be found forming parallel fibrous aggregates, colorless and with a vitreous luster.
It is known as the television stone for its ability to enlarge and translate images through its optical fibers.
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.
