Aztec Mine, Santa Cruz County, Arizona, USA
This chalcanthite specimen from the Aztek mine is likely another "encouraged" crystal. I suspect that a stone was suspended in the outflow of the mine, resulting in this pretty specimen that has reasonably clean chalcanthite crystals growing from all sides of the host rock. Pretty chalcanthite crystals coat nearly every surface at the outflow point of the mine. There is no sign of an attachment point. The crystals are deep blue and transparent, with a rhombic shape.
