This is a way beyond normal quality, stunning example of intergrown, splendent, silvery-white crystals of arsenopyrite. They reach to 4.5 cm in length. As it so happened, most of the crystals are also doubly terminated and this is just one of the finest arsenopyrite miniatures I can imagine, competing even with the best of Chinese material which has come out in abundance in recent years. There is a subtle curvature to the crystals in this specimen, and a sharper point at the termination, that together makes it stand out from Chinese material

This piece is particularly interesting because of its 3-dimensional saddle-like shape and smooth, even coloration. It is a hefty piece of good cabinet size, not too big and not too small. It is a beautiful color unlike smithsonite in this habit (rounded, or botryoidal) from other locales. Choix smithsonites really set a standard for "hot pink" color in the species. They came out in bits and spurts as recently as a few years ago in the mid-2000s but generally were blues and blue-green colors with some relatively paler pinks. These more intense pink specimens date back, generally to the 1960s-1970s. They are getting harder to come by on the market, found only when collections are recycled. from the Richard Heck collection. Joe Budd photos

A highly unusual calcite specimen showing a rich pink-red color due to cobalt, and from Germany! It is a quality I had not seen in any example of this for sale, only in dribs and drabs over the years. The piece is aesthetic and complete all around. In person it has a richer, darker toned color saturation. This is an old specimen from the Pearse Collection, Harvard University. See the Mineralogical Record's label archives: http://www.minrec.org/labels.asp?colid=1144 for information on John Pearse, (1842-1914) of Pennsylvania. The site notes: while in Freiberg for study in 1865 he purchased a 5000-specimen collection of minerals, rocks and fossils from the Academy's mineral dealership, the Mineralien-Niederlage zu Freiberg. Pearse never added any specimens to his Freiberg mineral collection. It was sold by his son Langdon (an 1899 Harvard graduate) to the Harvard Mineralogical Museum for $275, and the specimens were distributed throughout the systematic collections and teaching collections. Exchanged from Harvard by a collector in the past.
Have you ever seen a specimen such as this? This is, in my experience so far from China, truly unique for overall showiness and aesthetics. Sharp, brightly metallic arsenopyrite crystals to about an inch in length are set in a bed of gorgeous, drusy, sparkly purple fluorite. Some of the arsenos show minor damage, but this specimen is special not for its pristine nature so much as its dazzling combination of minerals – royal purple and gold! IN person, it is sure to impress!

I am told by many people that this may well be the best arsenopyrite from England, as an aesthetic specimen at least. Considering what simply average Chinese arsenopyrite costs (already high) and how common it is, puts this piece into a significant context. Limestone matrix and milky quartz host an aggregate of parallel-grown splendent, silver-colored crystals of arsenopyrite to 3 cm in length. The back side has been contacted but can't be seen when the specimen is properly displayed from its two frontal angles as shown here or as in the book photo. Mined in the late 1980's by miner J.G. Wilson: his label and that of Ralph Sutcliffe accompany this significant locality specimen. I find it remarkable that for such a locality rarity, even by any standard it is still extremely aesthetic and not a "black ugly" by any means.

Superb thumbnail of thick, elongated scalenedrons of very light Cobaltian Smithsonite. Such well-developed crystals, in this size (up to an amazing 2 cm) and thickness (4 mm) are quite unusual. These Smithsonites are lustrous, gemmy, and the cluster is quite aesthetic. Rarely will you find one this good. Ex. Georg Gebhard.

Very sharp grouping of elegant Arsenopyrite crystals, the largest reaching 2.3 cm. The luster is superb – so much so that this was very difficult to shoot, the surfaces were so bright. What really makes this for me, though, is the repeated stepped growth patterns that creates such aesthetic surfaces along the sides and termination of the crystals.
5.8 x 3.4 x 2.4 cm. The profusion of arsenos from China has overshadowed good specimens from other countries, which remain quite desirable. This is an old Chihuahua piece out of the collection of Scott Williams -- as you can see, showing superb sharp crystal form and luster!
12.6 x 8.4 x 4.2 cm. Sharp, metallic crystals of arsenopyrite in a fine balance with milky quartz crystals. The arsenos have a nice bronzy luster. On the back side of this large and impressive specimen is massive sphalerite.
9 x 7.8 x 3.2 cm. Outstanding combination piece consisting of Apatite, exceptional Arsenopyrite, clusters of Muscovite, and Quartz. The Apatite, 1.5 cm across and .5 cm thick, is a lovely gemmy green. The luster varies from excellent to coated. The lustrous Arsenopyrites are well-crystallized, almost fan-like in their habit. The Quartz is both massive as the base and well-crystallized, the few dings being of little significance. There are also numerous Muscovite inclusions in the gemmy Quartz crystals, which add even more to the aesthetics and mineralogical value of this excellent specimen. Ex. Steve Smale Collection.
8.6 x 4 x 2 cm. Lustrous doubly-terminated bladed crystal of Wolframite with a cluster of Stannite and Arsenopyrite crystals near the base of one side. The Wolframite has a luster that ranges from good to superb, and there are some areas of incomplete growth (contacts of some dings??) along some edges and one termination. The Stannite and Arsenopyrite have superb metallic luster, and excellent crystal form. They range up to .7 cm in size. Ex. Steve Smale Collection.
5.6 x 3.9 x 2.6 cm. Do not let the prolific finds of arsenopyrite in China jade you to the value of a fine old Panasqueira specimen! These are sharp, brassy crystals with pretty striated terminations, in association with accenting muscovite. Very pretty, classic stuff!
10.2 x 6.3 x 2.8 cm. The camera could not capture the super-bright metallic glimmer of this large cluster of sharp arsenopyrite - like shiny new nickels! The striations on the curved crystal faces cause them to shimmer in the light. On the surface are scattered small bunches of green muscovite.
4.9 x 3.9 x 1.9 cm. A cluster of razor-sharp crystals of arsenopyrite, with a silvery-to-brassy sheen.
12.4 x 10.4 x 5.4 cm. An AMAZING cluster of quartz crystals out of the collection of Ed David! These gemmy crystals are stacked upon one another as if by hand, with both terminations complete, sticking out on either side! The terminations on one side of the crystals are sprinkled with little yellow-tan muscovites. On the other side is a cluster of arsenopyrite (the quartz/arsenopyrite association is well-known from this locality). A show-stopper of a quartz specimen!
