Cassiterite on pegmatite matrix.
Cassiterite is a fundamental mineral for obtaining tin, which, in turn, is used in alloy with copper to obtain bronze.
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.
