Ferberite (rosette) and Quartz etc.
stock #8.1-088
Yaogangxian Mine, Yizhang County
Hunan Province, China
5.5 x 4.4 x 3.9 CM (small cabinet/ large miniature)
price: $425
Dec 2018

A 360 degree specimen hosting a delicate cluster of Ferberite crystals pointing in all directions and slender Quartz prisms. Very tiny Muscovite and a few Scheelites are also on the piece as is typical from Yaogangxian where complex multi specie specimens were typical. The longest slender Quartz is 4.2 CM and doubly terminated. Some contacting that is not very noticeable, several terminations are a ragged, complex type that adds some esthetic complexity. Very displayable and a choice piece from the locale.
Arsenopyrite (twin) on Muscovite and Quartz
stock #6.2-895
Yaogangxian Mine, Yizhang County
Hunan Province, China
4 x 3 x 2.7 CM (miniature)
price: $330
Dec 2018

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.
Fluorite -dark zoned
stock #14.1-415
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.1 x 3.3 x 2.5 CM (miniature)
price: $350
Dec 2018

very sharp single cube perched on a shard of matrix, mostly Muscovite. The Fluorite has very deep purple zones and masses on the outer edges the center core is transparent and a light blue color. Very glassy luster as in all the better Yaoganxian Fluorites. The display side is perfect damage wise, there is contacting and cleaves on the back. Better in person, this is from mining in the 2004-5 season when a very rich area was worked. The locality no longer produces anything like this.
Cassiterite -huge for locale, with Ferberite, Arsenopyrite, Chalcopyrite, Quartz, Muscovite, Stannite, Fluorite etc.
stock #18-AX-29-046
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.8 x 4 x 2.8 CM (miniature)
price: $1600
Late Summer 2018

The very best Yaogangxian Cassiterite I have ever seen, with the largest crystals as well. An excellent multi-specie piece mostly composed of superb Cassiterite. This locale has produced thousands of excellent mineral specimens but Cassiterite is very rare from this famed locale. Sharp lustrous crystals to almost 3 CM are arranged in a radiating cluster on a very complex matrix. I count at least 7 mineral species on this miniature, but the Cassiterite is clearly dominant and is in fine condition as well. A superb modern classic and a very important Yaoganxian specimen.
Arsenopyrite etc -
stock #8.1-170
Yaogangxian Mine, Yizhang County
Hunan Province, China
8.1 x 6 x 5.8 CM (cabinet)
price: $420
Worldwide mix summer

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.
Ferberite- doubly terminated
stock #18-AX-1-405
Yaogangxian Mine, Yizhang County
Hunan Province, China
7 x 2.6 x 1.3 CM (cabinet)
price: $240
Worldwide mix summer

An excellent sharp Ferberite crystal from the great Yaoganxian, with top bright luster. The crystal shows the distinct pointed tip termination that is the less common habit. Yaogangxian specimens are often multi-specie, there are almost always a few species on any specimen. This may seem like just a Ferberite crystal, but it has micro crystals of Fluorite, Quartz, Muscovite, Chalcopyrite and one small Bournonite. The color is jet black but looks metallic as it is so lustrous, in very good condition, a few contacts are visible but no real damage at all. Ferberite is not often attractive, but good lustrous crystals like this are.
Fluorite, Ferberite on Quartz with Muscovite and Arsenopyrite
stock #18.1-AX-15-246
Yaogangxian Mine, Yizhang County
Hunan Province, China
6.7 x 5.2 x 4.3 CM (cabinet)
price: $375
Worldwide mix summer

A choice multi-specie specimen from Yaoganxian, ex Shields Flynn collection. The Quartz in person is very clear, has a sharp termination and you can see Ferberite and Muscovite inside. There are unknown white inclusions inside as well. The Ferberite is lustrous, and the Fluorite is transparent as it should be. Not perfect however, when seen under 10x magnification there are rough spots and the smaller Feberite has chipping, but the overall quality is far better than average and this has the sort of esthetics that displays very well. The price reflects the imperfections which for many collectors makes this a very good value.
Wurtzite with Quartz
stock #18-AX-15-323 (CO93)
Yaogangxian Mine, Yizhang County
Hunan Province, China
8 x 6.7 x 5.8 CM (cabinet)
price: $2600
Spring update

A superb, major specimen of well crystallized Wurtzite perhaps the best example from the great Yaoganxian Mine. By far this is the best and biggest specimen I have seen from this prolific locality, and was on exhibit in the Tucson TGMS special exhibit of Chinese minerals a decade ago. Ex Shields Flynn collection obtained from Bert Ottens who originally discovered Wurtzite at Yaoganxian. Nearly pure Wurtzite, there are hundreds of sharp crystals to 6 MM on all sides with just a few Quartz crystals as contrast. In fine condition and although a "dark ugly" it is oddly attractive. Several have considered this the very best Wurtzite from China, it is obviously important for the locale and the specie.
