About Chalcanthite

Chalcanthite is a secondary mineral, which is a natural, water-soluble copper sulfate (CuSO4·5H2O). It forms in arid climates or in rapidly oxidizing copper deposits. Furthermore, it often forms on mine walls due to the action of acidic surface waters on copper veins. The copper oxidizes and reacts with sulfate-rich groundwater and the chalcanthite crystals do form as the water evaporates. It ranges in color from green to the more common blue. Chalcanthite crystals are transparent or translucent. They are soft with a hardness on the Moh’s scale of only 2.5. Chalcanthite breaks easily and has a sharp, brittle texture.

On the other hand, it is possible to grow chalcanthite specimens in labs, and many of the specimens out on the internet for sale are artificially made. In effect, they are easily recognizable by the lack of rock material, dirt, or smaller green crystals. They are simply too perfect to be true.

There are many synonyms for Chalcanthite. The word derives from the Greek and means “copper flower“. One can find it called blue vitriol, cyanose, cyanosite, copper vitriol, or calcantite. Overall, it has about 20 synonyms or varied names in different languages.
