EnargiteEnargites from the famous Longfellow Mine are amongst the best in the state, and these pieces are incredibly difficult to find in good display specimens such as this. This particular specimen is from my own personal collection, and actually once belonged to Warren Prosser, the noted author and geologist who worked in the San Juan Mountains of Colorado. The piece plays host to dozens of sharp, rather lustrous, attractive, metallic silvery black

colorless hexagonal prisms of Quartz included with rarely seen beautiful pistachio green Epidote “needles”

It's very exciting to see specimens of this calibre coming out of the ground

If you collect rarities

Peruvian minerals or just aesthetic display pieces of rare species
