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.

Esthetic Galena crystal that is well-exposed, sits at the top of mixed specie matrix. The main Galena is complete, sharp with some face etching, and is a modified cubo-octahedral form. From the famed mines of Dalnegorsk, which has been the source of some of the world's best Galenas. Displays well from almost any angle, there is no damage seen, and the luster ranges from satin to mirror bright.

A perfect example of so called interference Quartz. For any Quartz suite this is a fine, exotic and strange form. From Dalnegorsk a few years ago this came from a small find and this was one of the largest crystals and one of the very few that were complete and undamaged. It seems that in this location at least as the Quartz grew it had a series of thin Calcite blades on each side. The Calcite has since dissolved away but had an impact on the crystal development. The result is a remarkable stepped form in an inclined series of ridges. Unusual and certainly esthetic in a strange way!
A complete and perfect elongated crystal of Pyrrhotite is perched on a complex crystalized matrix. The Pyrrhotite looks very much like two crystals side by side but is in fact a single crystal. Fine stepped growths and silky patina on all sides of the specimen. The Galena and Sphalerite are both very lustrous and the whole piece is damage-free. An older specimen from Dalnegorsk, this is vintage about 1996.

A bright metallic, flat crystal of golden Pyrrhotite that is perched on a little Galena. From the prolific finds at Dalnegorsk, this looks nice from either side, and is in very good condition. The crystal is undamaged, has no chips but is contacted and recrystallized on one edge. The wide flat face shows some multiple stepping as well. The crystal has some patina and slightly variegated luster.

Nicely composed miniature from the great Dalnegorsk deposits, ex Charles M. Noll collection. The Pyrrhotite crystal is perfectly perched, the wide terminal face is a brassy, slightly subdued hue and the edges are a brilliant golden with mirror bright luster. In perfect condition with no damage seen even with magnification. There have been many good Pyrrhotites found at Dalnegorsk yet it can be hard to find a miniature with standout quality and esthetics. Better in person.
