Pyrrhotite - rare penetration twin
Dalnegorsk, Kavalerovo Mining District
Primorsky Kray, Russia
4.1 x 2.9 x 2.8 CM x 2.9 (miniature)
price: $760
Pre Tucson
Textbook perfect, complete and sharp this is an unusual type of twin for Pyrrhotite. With small areas of Galena and Sphalerite, this is essentially all Pyrrhotite. In excellent condition as seen, no damage at all but the usual tension cracks are seen as is typical though there is no repair or instability. Great golden patina and displays well from most any angle, a choice Dalnegorsk piece and an excellent twin Pyrrohotite. Since Pyrrhotite is generally found in hexagonal crystals, the penetration twin has 4 terminations showing with six sides on each end, all at 90 degrees from each other. This is only the second such twin I have ever seen.
