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.
From Wikipedia, the free encyclopedia. Chalcanthite, whose name derives from the Greek, chalkos and anthos, meaning copper flower, is a richly-colored blue/green water-soluble sulfate mineral CuSO4Â·5H2O. It is commonly found in the late-stage oxidation zones of copper deposits. Due to its ready solubility, chalcanthite is more common in arid regions. Chalcanthite is a pentahydrate and the most common member of a group of similar hydrated sulfates, the chalcanthite group.
