Natural Chalcanthite crystals are very rare in nature. Well-formed crystals are easily grown synthetically from copper sulfate solutions. This can be done by dissolving a readily available chemical salt called copper sulfate, and then letting the water evaporate. This leaves behind a crystallized mass of Chalcanthite which can crystallize beautifully if grown properly. If a Chalcanthite crystal looks to good to be natural, it probably is, as good natural crystals are very hard to come accross.
