Pyrrhotite (unique form - uncommon locality)

Item Description

The Morro Velho Mine first and foremost is a gold mine, and it has the distinction of producing some really singular mineral specimens. The Pyrrhotites from this locality are few and far between on the market, especially in specimens like this with big crystals showing unique morphology. This piece is a beautiful dark brassy colored, pseudo-hexagonal group of layered crystals showing a combination of smooth, broad faces and contrasting stark skeletal forms on both sides. The piece displays well from either side and presents nicely as there is something different and unique to see from each side. This style/form is not just rare for Morro Velho, but I can't remember seeing another Pyrrhotite like it from any mine. A really attractive and interesting specimen from decades ago (circa 1970s) and if you collect sulfides or Brazilian minerals, don't miss out, as you're not likely to see another like anywhere else.
From the collection of the recently deceased Alvaro Lucio, arguably the most well-known and accomplished mineral dealer and collector in Brazil. Alvaro graduated with a degree in civil engineering, mining and metallurgy from the Escola de Minas de Ouro Preto in 1949. He began his PhD in the United States and completed it at the Federal University of Minas Gerais. He worked as a professor of extractive metallurgy at UFMG, and also as a technical consultant for several companies in the sector. He was the author of several works, published in books and magazines around the world. He received several honors for his contribution to the development of metallurgy and the introduction of metallurgical physical chemistry in Brazil. His knowledge, solicitousness and enthusiasm will be greatly missed in the mineral world.
