Teniente Mine, El Teniente, Rancagua, Cachapoal Province, O'Higgins, Chile

13.4 x 11.3 x 8.7 cm. This is the largest and best crystallized natural chalcanthite that I have personally seen. It has a huge complete crystal of neon blue, sticking straight up from matrix. It is pristine, glows when backlit, and is from an old-time locality. Chalcanthite is easily synthesized today and grown in labs all around the world for ...

A rare locality piece of an already rare copper species, with sharp crystals! Nestled in the matrix are several, lustrous, teal blue, platy, crystals of chalcophyllite, to .3 cm across. There is also a thin druse of azurite around the perimeter of the vugs. Very showy and rich, for such a rare piece. 7.0 x 5.3 x 3.9 cm
