Largest one I have ever seen. Shocker of a living room display. Chalcanthite is one of only a few water soluble sulfate minerals. This fact drives much of what is interesting about this mineral. It forms in the near-surface secondary oxidation zone of copper deposits usually late in the development of these deposits. Since it is so soluble, it may crystallize, dissolve and recrystallize again and again before the deposit is discovered. Chalcanthite loosely translated from the Greek means copper flower . An apt name for this attractive mineral. Synonyms include "blue stone" and "copper vitriol" . Chalcanthite is the name of a group of only four triclinic sulfates of which chalcanthite is its only common member. Other members have in place of copper ions of iron, manganese and magnesium.
