Malachite (unusual ''stalactite'' specimen - rare locality)

Item Description

A most unusual and incredibly hard to find specimen of stalactitic Malachite from the Tentadora Mine. Before this discovery, Malachite had not even been reported from this locality before. Several beautiful "balls" of bluish-green Malachite are stacked on top of one another to create the beautiful large thumbnail sized specimen. Interestingly, the center portion of the piece is hollow, but not in the typical tubular shape you would expect, it's more geometric, almost as if the Malachite formed around another mineral which later dissolved away (Gypsum?) to create a beautiful "cast" (epimorph / perimorph) inside. If you collect secondary ore minerals, unusual morphology or if you just like interesting miniatures, do not pass this one up. It came from a very limited find, and few were available.
