"Regarding mineralogical features this mine is well known internationally. Since the beginning of the 1980’s it has been providing outstanding specimens of fluorite whose crystals have colors varying from colorless to deep violet. This fluorite is frequently associated with calcite, baryte and quartz. They also display a special characteristic, a true hallmark of the specimens coming from Emilio Mine: the great variety of the habits and combinations of the isometric system that occur in the mineral crystals."

A super Panasqueira specimen with Apatites (to 2.5x1.75x1 cm), Muscovite, Arsenopyrite, Pyrite & Calcite. Difficult to photograph and even better in person.
In fine condition.
Panasqueira has yielded many of the best Apatites in the world, but this mine is not only known for Apatites. It has produced a exceptionally large suite of other minerals that also rank among the very best for the species. However, the amount of fine crystallized different minerals one can find in just one specimen is what sets apart this locality.
A solid mass of silvery Pyrite crystals with intergrown, light Amethyst crystals.
Hundreds of fine, glassy Hemimorphite crystals on a matrix of Limonite. Named Hemimorphite because of the hemimorph development of its crystals. This unusual form, which is typical of only a few minerals, means that the crystals are terminated by dissimilar faces.

Uvite is the magnesium/iron-rich member of the Tourmaline group

The San Juan Mountains are a rugged mountain range in the Rocky Mountains in southwestern Colorado. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining is now uneconomical in the region, although independent prospectors still work claims throughout the range (From Wikipedia, the free encyclopedia).
