Crystallized stilbite of pale yellowish pink color.
Stilbite is a common member of the zeolite group and is found in most of the world's major zeolite deposits.
Its uses are restricted to collecting and in industry, as it is a mineral that can lose water, is exposed to high temperatures and serves as a purifier in contaminated water.
The mineral includes a label with the name and origin and is attached to a 4 cm square cardboard box.
*The price is per unit (a single cardboard box of the four shown in the image)
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.
