An exceptional Spinel galena from the John Marshall Collection. Textbook perfect clusters of Spinel twins reaching 4 CM are esthetically placed on a complex matrix of fine quality Chalcopyrites and minor quartz, sphalerite etc. One large Chalcopyrite (2.4 CM) is also a textbook perfect crystal and is perched at one end of the specimen. There is a lot of Galena from Dalngorsk but fine spinel twins from there have become quite rare (they were never common in top quality). This one has both excellent condition and esthetics.

Fantastic array of fine, orange red Sphalerites covering the contrasting matrix. Formerly in the John Marshall collection with his labels and catalog card, he obtained this piece in 1984. This type and quality has not been available for many years now. Esthetic and with uncommon color, this is very eyecatching. Most crystals are in perfect condition except near the outer edges. A very good investment for any collection.

A single, big, elongated chalcopyrite crystal showing fine striations and luster. Most faces are perfect and shiny, but there is slight chipping on a few edges, not significant given the size of the crystal. Although Chalcopyrite is a common mineral, crystals that are complete of this size are rare. Madan has produced a few superb examples.
