Fluorite (phantom) on Muscovite etc.
stock #8.1-077
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.3 x 5.6 x 4.8 CM (cabinet)
price: $950


Perfect, with killer color, transparent Fluorite crystals aesthetically perched on a mix of smaller Fluorites and Muscovite. The luster and color zoning are exceptional, there is no damage and the main cubes show penetration twinning. This piece shows very well the quality that made the Yaogangxian Mine's reputation. The cubes have several separate phantoms and a more diffuse core color of vivid purple. An older specimen from 2008, this is quite different from more recent finds and is simply a super piece in person.
Bournonite with Quartz
stock #18-AX-15-164 (C147)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
6.5 x 4.7 x 3.8 CM (cabinet)
price: $1150


A cluster of large Bournonite crystals that are complexly intergrown with only a single Quartz crystal as matrix. Ex Shields Flynn Collection, this has the fine "gun-metal" luster that is most desirable from Yaogangxian Bournonites. Some crystals exceed 3CM and show flat terminations and classic cogswheel form twinning. In very good condition despite some small bruises this is in far better condition than most. This specimen was displayed in the Tucson show special exhibit on Chinese minerals. This was an early (2000's vintage) obtained by Shields from Bert Ottens in the golden years of Chinese mineral finds.
Fluorite on Quartz
stock #18-AX-18-019
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
9.3 x 4.8 x 3 CM (cabinet)
price: $260
Spring 2020

An unusual etched gemmy cube of Fluorite is perched on a clean white crystalized Quartz matrix. Overall in fine condition as seen, the Fluorite has a hopper-like form with complex structure best seen in person or under magnification. A large amount of fine Fluorite has come from Yaoganxian over the years but this habit is very unusual. Strong blue color and high luster make this a nice choice.
SOLD Arsenopyrite - exceptional iridescent crystals
stock #SOLD 20.1-096
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.1 x 4.1 x 3.3 CM (small cabinet/ large miniature)
price: $0
Spring 2020

Simply extraordinary, a killer Arsenopyrite cluster of sawtooth edged crystals with the very best Iridescence I have ever seen on the specie. From Yaogangxian, this has several small crystals of Fluorite, Quartz Muscovite etc) as is typical at this locality. What is not typical is the brilliant patina on this specimen. A vivid rainbow of colors, this is super in person. I have seen only a few other iridescent Arsenopyrites but never present on more than a few faces and much less brilliant. This specimen is in exceptional condition, undamaged and displayable from any side a rare 360 degree piece. The Arsenopyrite crystals are very sharp and clustered in stacks and epitaxial arrangements. From a small find in late 2018
Fluorite and Quartz
stock #18.1-521
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
6.3 x 5.6 x 4.3 CM (cabinet)
price: $260
Spring 2020

The main Fluorite cube is very sharp, multi colored (blue, green and with amorphous zones of a violet purple). The main cube is 4.7 CM on edge and has very sharp corners. The Fluorite is perched on a pair of Quartz crystals and is contacted / incomplete on the back side but undamaged and choice from the front and sides. A zone of golden colored suphide druse is noted on one face that adds a nice contrast. Good rich color and transparency, a nice Yaoganxian specimen from the period when the mine was still working at full capacity.
Pyrrhotite rosette on Arsenopyrite
stock #6.2-885
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
4.2 x 3.6 x 3.2 CM (miniature)
price: $750


A flower form composed of thin blades of Pyrrhotite crystals esthetically perched on sharp crystals of Arsenopyrite. A rare specie from the famed Yaoganxian mine these were found almost 2 decades ago, we have not seen any since. The main flower is 3 CM across with a dark metallic patina. The Arsenopyrite crystals are highly lustrous and sharp. Overall in fine condition, one edge of the main flower has what seems to be a small old rehealed break or edge contact, not at all distracting, otherwise the display side is perfect. A very choice Sulfide from anyplace and a superb piece for the legandary Yaoganxian or for that matter all of China.
Fluorite, Arsenopyrite, Calcite, Muscovite and Quartz
stock #19.1-420
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.2 x 5.8 x 4.9 CM (cabinet)
price: $850


A long list of species on this early (2000) Yaogangxian specimen that features a prominent bright purple Fluorite. The Fluorite is a stepped cube that shows perfectly the stairlike form of this habit. In excellent condition, this has an intense deep color and contrasts with the other species on the specimen. Esthetic and an unusual habit for this famed locality, the stepped form is better known in Green crystals from Shangbao (Hunan Province) but very rare at Yaoganxian.
Stannite, Quartz and Arsenopyrite
stock #AX-15-251-(C288)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.1 x 4.3 x 4.2 CM (cabinet)
price: $650


From the "golden age" of mineral finds at Yaogangxian, this is a super choice Stannite. Ex Shields Flynn collection, the Stannites are bright brassy, well formed, undamaged and very rich. This specimen was exhibited at Tucson in the TGMS displays in 2005 celebrating the minerals of China. Most pieces from this find had much more Arsenopyrite and or Sphalerite than Stannite, this is almost all Stannite with clear Quartz crystals adding a nice accent. Most will agree that the old Yaogangxian finds were the best ever found. This specimen is well better than typical and now Chinese Stannite is rarely available in such size and attractive quality.
