Wurtzite with Quartz
stock #AX-15-323-(C093)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
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, Chenzhou Pref.
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 #AX-15-013
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
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, Chenzhou Pref.
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, Chenzhou Pref.
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.
Scheelite on recrystallized Quartz with Fluorite
stock #AX-12-404
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.6 x 5.5 x 1.3 CM (cabinet)
price: $290
Spring 2017

A very unusual Yaogangxian specimen with the matrix a flattened Quartz shard that has recrystallized with one face coated with these clear Scheelites, the opposite side is dusted with clear tiny Fluorites. In fine condition, the Scheelites are bright and glassy, micro Pyrites are seen on some Scheelite crystals. Formerly in the Shields Flynn collection, this is quite choice (and certainly not typical) for this famed locale. Attractive.
Fluorite on Quartz and Muscovite
stock #6.2-849
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
3.9 x 2.7 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $210
Spring 2017

A small bit of perfection, this is a transparent pale-blue cube with purple core phantom perched on a small matrix of Quartz. Classic Yaogangxian Fluorite from finds of 2003 vintage. The condition is flawless. The Fluorite is sharp and more transparent than the photos show. This could be trimmed to thumbnail size for competition but we like it as is. Choice.
Pyrrhotite replaced by Pyrite and or Chalcopyrite
stock #6.2-566
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.5 x 4.2 x 3.3 CM (cabinet)
price: $120
Spring 2017

An oddity from the great Yaogangxian Mine, sharp rosettes of Pyrrhotite (rare at this locale) that are coated by secondary Sulphides and associated with Chalcopyrite and Pyrite. The Pyrrhotite has been partly or entirely replaced by what is likely pyrite but could also be Chalcopyrite. Both species are on the specimen's matrix. Delicate and well-formed this was part of a small find we obtained at the mine in 2003. I have not seen these since then. Uncommon and a nice example for any good Yaogangxian suite.
