This Chalcanthite is impressive for its color and luster. The blue tone is very intense and changing under the sunlight and the luster is equally powerful. Very beautiful are the zoom photos in which prismatic crystals of great translucency are observed.
It is a rare mineral, due to the conditions in which it is formed, and comes from Jiangxi (China). As it is water-soluble, contact with water should be avoided
