Item Description

Although the Sweet Home mine is most famous for it's Rhodochrosite specimens, there are several good sulfide species from this prolific locality that do not get enough attention. This piece is one of the best Enargites from the Sweet Home that I have had to offer. A few sharp, striated, isolated, metallic grey-black, tabular crystals measuring up to 1.5 cm sit atop a matrix of crystallized grey-white Quartz with associated bright metallic pyritohedral Pyrite crystals. The specimen is from the well known Colorado collection of Richard A. Kosnar, and is accompanied by a Colorado School of Mines label. The specimen is 40-50 years old, and stands out amongst many other lesser quality Enargites that I have seen from the Sweet Home, from both old and recent mining projects. If you're a Colorado collector, or a collector of classic sulfides, do not miss out on this one.
