A perfect main Arsenopyrite crystal with textbook form well perched above the matrix of Muscovite and Quartz crystals. Brilliant metallic luster, no damage and great esthetics, a very choice miniature for the specie. The main Arsenopyrite is just over 2 CM and has a penetrating crystal (twin) that is in a X form, but is not very evident from the logical display angles. From finds almost 10 years ago at Yaoganxian. Hard to photograph the brilliant luster, this is great in person.

A very unusual style of Arsenopyrite from the famed Yaogangxian mine. A small amount of Muscovite matrix and associations of Fluorite (small clear purple crystals), Quartz and Calcite are typical in these multi specie specimens, but by far the majority is Arsenopyrite. Unlike the usual silver color, this has the bronze-golden hue that was only found in one zone about 15 years ago. Chipping and bruising on the outer edges is clearly seen but all the main crystals are intact and very sharp. As well as the unusual color, several crystals have unusual habits although most of the largest crystals are more usual forms most of which are in parallel position. Despite the edge damage this is a choice piece.
An exceptional, elegant Pseudomorph ex. Ed Swoboda's fine collection of Psuedos. Likely mined pre 1970, there is nothing like this on the market. Tapered, curving crystals of the original Pyrrhotites formed a very esthetic cluster and reached to 5.3 CM long. The replacement by Arsenopyrite seems to be complete and has a brilliant sparkling luster. Minor associated Sulphides are seen but this is almost entirely Arsenopyrite/ Pyrrhotite. In great condition as seen, this displays well from all angles. A fine addition to any Pseudo collection, Mexican or Sulphide suite,
Simply a very esthetic and bright shiny Arsenopyrite with first rate presentation. EX Irv Brown Collection. Good Huanggang minerals are now the most sought after Chinese specimens and this is a particularly well composed piece in excellent condition. Displays well from all angles.
Simply put, this is a huge, gleaming, esthetic and fine Arsenopyrite from Yaoganxian. Arsenopyrite is not rare, but great form with huge, undamaged crystals are. The largest here is 6.3 CM and doubly terminated. Brilliant luster, nice architecture, impressive display face and outstanding for the species. I have never seen a better example for sale from any locality. Yaoganxian Arsenopyrites rank with the best, I think eclipsing Panasquira, Cornwall and Peru. This specimen is 2002 vintage. Contacting and removal damage is limited to the rear base area, not visible on display. Although this might seem expensive for a common, metallic mineral, this is an incredible value for a top display piece!
