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.
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.
Fluorite on Muscovite and Quartz
stock #4.2-220
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.2 x 4.1 x 3.2 CM (miniature)
price: $190
Spring update

Glassy transparent and sharp cubes with areas of deep purple color zoning. The matrix is visible through the Fluorites. No damage. This sort of Fluorite once came out in large amounts from Yaoganxian, though undamaged pieces were much less common. A modern classic location, the supply of nice pieces is drying up but some are still relatively affordable.
Fluorite on Quartz with Pyrite, Bournonite
stock #18.1-AX-15-013
Yaogangxian Mine, Yizhang County
Hunan Province, China
10.8 x 7.8 x 8.7 CM (cabinet)
price: $550
Spring update

Quartz crystals to 9.5 CM decorated with sparkling purple Fluorite and small Pyrites, Bournonites etc. Impressive and very attractive (better in person) this is in fine condition, an unusual yet very esthetic display piece from the great Yaoganxian mine. This locale has produce thousands of good specimens but undamaged Quartz of this size and quality were very rare. With the colorful presentation of the accessory minerals this becomes something really special
Fluorite on Quartz with Calcite
stock #16.1-346
Yaogangxian Mine, Yizhang County
Hunan Province, China
10.7 x 6 x 4.4 CM (cabinet)
price: $660
Pre Holiday 2017

An impressive Yaoganxian specimen with gem clear Zoned/ phantom Fluorites scattered on sizable clear Quartz crystals. Ex Charles Noll collection, an older specimen. Very 3-dimensional with top quality color and sharpness for the Fluorites. The backside and base of this are contacted and broken where it was removed which can not be seen on display. The display side is in impeccable undamaged condition which is rare. One of the worlds top mineral locales, Yaoganxian now produces almost nothing, this type of quality is only found in older collections.
Bournonite on Quartz
stock #8.1-250
Yaogangxian Mine, Yizhang County
Hunan Province, China
8.8 x 4 x 3.2 CM (cabinet)
price: $280
new june 17

A lustrous Bournonite is perched on one end of a doubly-terminated Quartz crystal from Yaogangxian. Remarkably, the entire specimen is fully crystallized and complete on all sides, it is a floater. A modern classic specimen- vintage 2004, the great era of Yaogangxian production. The Bournonite has well defined crystal faces on the front side, however the back side is less distinct, more complex, yet still perfect and undamaged.
