Copper Sulfate


Chalcanthite is a delicate mineral admired and collected because of its intense blue color. It is a water-soluble sulfate that forms in mine walls in copper deposits. Chalcanthite has several alternative names, including blue stone, blue vitriol, and copper vitriol.

Chalcanthite is often found in arid regions because of its solubility. Its name comes from the Greek words “chalkos” and “anthos”, meaning copper flower. These crystals are grown in a lab in Michigan.

Note - Chalcanthite is a moderately toxic material, sometimes used as a pesticide and fungicide. It should be kept out of the reach of small children, and should be handled with care.

The Evolution Store carries a variety of beautiful, collectable mineral specimens!
