Aesthetic Blue Calcantite Natural

From our selection of collectible minerals we present a notable group of Calcantite crystals from the Baccu Locci Mine, Villaputzu, Sardinia. It is also characterized by large acicular and prismatic crystals of an intense natural blue color, arranged in a dense aggregate covering the robust brown-ochre contrasting matrix, with dimensions and aesthetic quality that increase its aesthetic value and mineralogical importance. The specimen stands out for the quality of crystallization and for the overall aesthetic balance, with features that highlight its natural structure and visual impact. Calcantite is copper sulfate pentahydrate (CuSO4·5H2O) whose characteristic blue color derives from the presence of copper in the crystal structure. It is a highly water-soluble mineral and is hygroscopic, typically formed by oxidation of pre-existing copper sulfides in an arid environment. The Baccu Locci Mine, in the Villaputzu area of Sardinia, is a historic site known for producing Calcantite samples of aesthetic quality. This is an ideal specimen for mineral collections, display, and for those who appreciate the natural beauty of minerals, even in the field of crystal therapy and lithotherapy, according to the properties traditionally associated with the mineral species. All minerals are 100% natural and untreated, except for very rare exceptions always noted in the description. The photographs are taken with professional lighting to best enhance colors and details; however, slight shade variations may occur depending on the device or ambient light.
