- Chalcopyrite with Galena and Siderite
- Small Cabinet, 8.4 x 7.7 x 3.4 cm
- Georg Mine, Willroth, Wied Iron Spar District, Westerwald, Rhineland-Palatinate, Germany
- Ex. Kay Robertson
The Wied Iron Spar District produced a plethora of classic specimens many years ago, and this is one of the best Chalcopyrites among them that I have seen. The curved, stepped Chalcopyrites reach an impressive 2.7 cm on edge, and they have a rich, brassy-gold color and good luster. The size and extent of the cluster is significant, and it rests on a matrix plate of Galena coated by Siderite crystals. There are even well-developed Galena crystals on top of the Siderites, like little moons orbiting the main Chalcopyrite cluster. This is a terrific and vintage German specimen, and it is better in person. Very good aesthetics, very good display quality, and significant for the Continent. Note that we are basing this locality information on photos in MINDAT, to which this looks similar. Kay's label says "Georg Mine" but gave a different state in Germany. ex. Kurt Scholer (1906).
