Siderite ps. Pyrrhotite with Galena and Chalcopyrite

Item Description

Intriguing and distinctive pseudomorph combination of Siderite ps. Pyrrhotite from a classic older European locale, which does not produce as much today as it used to. Definitely not your expected or normal pseudomorph! There are six hexagonal crystal groupings, up to 3.7 cm wide, of stacked thin sheets of Pyrrhotite crystals that have been completely covered with tiny lustrous amber colored Siderite crystals. The Siderite has pseudomorphed the Pyrrhotite at least on the outside edges and the exposed end faces of the groupings as can be seen on the specimen. Whether it has completely replaced the Pyrrhotite throughout the entire crystal is hard to determine. The piece is further accented with lustrous, sharp, battleship-gray Galena cuboctahedrons to 2.9 cm. As well as brassy Chalcopyrite crystals and a few small black Sphalerite crystals. The piece is in excellent condition with some normal periphery edge wear. This is one of the coolest pseudomorph "mineral nerdy" pieces from the Herja mine. An unusual and exceptional partial to full pseudomorph specimen that one rarely comes across. Ex. Kurt Hefendehl Collection. Valued $2500.
