What type of mineral do you think this is? Where can it be found?
This blueish hunk is chalcanthite, a crystalline mineral. It is often found in arid climates, such as Chile and Spain.
Does it have any practical use to humans?
Chalcanthite is often a prize for collectors, because of its beautiful azure color and its crystalline shape. Chalcanthite contains copper and can be used as an ore for copper extraction, which can then be used for fertilizers or other industrial purposes. It is considered toxic to humans.
