Krohnkite (rare form) ex Elling Coll.

Item Description

A SOLID, OLD-TIME and SHOWY specimen of the RARE sulfate, krohnkite, from the Type Locality, the Chuquicatmata Mine of Chile. Without question, this specimen exhibits the most intense teal blue color I have ever seen in a natural mineral specimen and has great translucence! And the variation in blue color, in itself, is very noteworthy. The piece exhibits what is HIGHLY UNUSUAL for the species, having blocky, cavernous, crystal form. The usual classic for the species are lamellar growth of curved crystals in parallel bundles. The UNRETOUCHED backlit photo highlights the gorgeous blue color saturation. Value??? Ex George Elling Collection.
