Massive Calcanthite in an intense blue crust.
Chalcanthite is an important copper mineral in areas where it is found in relative abundance, such as Chile and Spain. This mineral is known for being extremely soluble in water, which is why it is only found naturally in areas with a very dry climate.
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.
