Kröhnkite : Na2Cu(SO4)2·2H2O

Chuquicamata Mine, Chuquicamata District, Calama, El Loa Province, Antofagasta Region, Chile

A very rare and exceptional specimen with elongated, translucent crystals to 4 cm. This is a superior specimen of a quality I have not seen for sale before. Krohnkite is extremely fragile and large crystallized specimens, as opposed to massive specimens, are almost impossible to get. The pics say it all 5.4 x 3.6 x 2.4 cm

Kröhnkite : Na2Cu(SO4)2·2H2O

Chuquicamata Mine, Chuquicamata District, Calama, El Loa Province, Antofagasta Region, Chile

WOW! This is a MAJOR crystal of a very rare species, from an important and completely defunct locality! Krohnkite usually occurs as small crystals, or as lamellar aggregates filling fissure seams. Freestanding crystals are rare and those of several cm are already major for the species. This one is a whopping 8.5 CENTIMETERS! The crystal is fully ...

This super-rich specimen of kroehnkite still has the $500 label with it from the dispersion of the Hauck Collection, and when you see it, you will know why. The layer of kroehnkite is 2.5 CENTIMETERS THICK and is gorgeous! And, it has the almost unnatural-looking blue color that makes this sodium copper sulfate so unique. Good kroehnkites are just ...
