About Chalcanthite
Hydrated copper sulfate, forming beautiful blue crystals, but it is water-soluble and toxic if ingested. Energetically, it's linked to communication and flow, but primarily a collector's mineral requiring careful handling.

Geological & Scientific Details
Chalcanthite is classified as a sulfate mineral mineral which typically crystallizes in the triclinic system. Its chemical formula is CuSO4·5H2O. Common crystal habits include typically stalactitic, encrusted, reniform or massive. natural crystals are rare, but are short prismatic or tabular.
