Wurtzite, Bismuthinite and Quartz etc.
stock #6.2-842
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.2 x 4.3 x 3.2 CM (small cabinet/ large miniature)
price: $750
Pre Tucson

A well-formed Wurtzite crystal cluster on a complex multi-specie specimen from the amazing Yaogangxian Mine. The specimen has several Quartz crystals that are partly coated with Muscovite and sprinkled with metallic hairlike crystals of Bismuthinite. The Wurtzite is mostly seen in a 2.2 CM diameter cluster of stacked brown-red crystals that have a bright luster. In some photos these look silvery metallic due to the reflections on the surface but in hand the color is typical dark brown to almost black. Wurtzite from Yaoganxian is a very rare specie, this is the largest and best we have seen and is exceptional for the locality.

Fluorite - unusual stalactite form
stock #23.1-232
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
9.8 x 3.7 x 3.2 CM (cabinet)
price: $390
Spring 23

Stalactite of translucent Fluorite composed of small stepped crystals in stacked clusters. An early and very odd Fluorite from Yaogangxian, certainly a special and maybe unique piece. We have never seen another quite like this despite decades of experience with Yaogangxian. A few years ago there were some other type Stalactites recovered from a single pocket but they were composed of large crystal chains and a different habit altogether. Near the bottom of this piece there seems to be a repair on a crack. The rest of the piece is in perfect condition and for a perfectionist the repair could easily be unglued leaving an unrepaired, pristine (though slightly smaller) piece. A fine addition to any world-wide Fluorite suite or Chinese collection.

Pyrrhotite with Chalcopyrite coating
stock #21.1-344
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.2 x 4.8 x 3.3 CM (cabinet)
price: $480
New Year 22

An uncommon and attractive Yaogangxian specimen. Lustrous iridescent Chalcopyrite covers most of a stack of flat hexagonal crystals of Pyrrhotite. Only on a few edges are the original golden metallic Pyrrhotite crystals visible. In excellent condition, what may look like bruising on some edges is actually perfect and sharp. The multicolor patina on the Chalcopyrite is bright and sparkling which is both esthetic and very different for this famed locality. Individual Pyrrhotite hexagons are up to 5 CM across yet are unusually thin at just 2-3 mm on average. A choice Chinese Sulfide!

Arsenopyrite - iridescent crystals
stock #8.1-238
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
8.3 x 4.6 x 3.4 CM (cabinet)
price: $360
Early summer 2021

Large and lustrous, the Arsenopyrite crystals here have a golden patina on the broad faces and a bright silvery color on the narrow faces. The golden faces have a color play in the patina and are especially attractive. The facing side of the specimen is in great condition. Part of the sides have contacts and there are saw marks on the back as well. None of those distractions are visible in a normal display. This presents deep striations and classic habit, the bigger crystals are over 4 CM and very clearly defined. Tiny bits of Quartz and Fluorite are also present. An older specimen (2008) from the great Yaogangxian.

Fluorite included by Boulangerite
stock #8.1-164
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
8.2 x 5.9 x 4.3 CM (cabinet)
price: $470
new year 2021

A dark purple cluster of Fluorite cubes with slightly rounded faces that are thickly packed with masses of Boulangerite hairs. In many places the Boulangerite is protruding from the Fluorite making complex nests of metallic wire-like crystals. The specimen is an older (2004) vintage piece from Yaogangxian and is a super example of this association. The Fluorite is transparent to translucent and with magnification the Boulangerite inside the crystals is seen as straight hairs, curved wires and coiled spirals, loops and rings. This find of included Fluorite was remarkable and this specimen is a superb, large example. The specimen is a mix of larger cubes up to 2.5 CM to masses of tiny curved cubes in clusters.

Scheelite with Calcite
stock #16.1-395-(CN3488)
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.4 x 5.1 x 3.3 CM (cabinet)
price: $650
new year 2021

A very fine Scheelite from the famed Yaogangxian Mine, ex Charles M. Noll collection. The Scheelite is very sharp and glassy, very large for this locality, and has a color that looks like a brown stout or root beer hue in reflected light. When backlit with a strong light source the color is more reddish-purple. Transparent on the edges but translucent overall the Calcite adds a very nice accent. The bottom of the piece is broken where it was attached but some of that area is recrystallized. Fine luster and great striations on the glassy faces help set this piece apart. From the "golden years" at Yaogangxian this is really fine for the locale and a choice dark Scheelite from any place.

Fluorite on Muscovite with Quartz
stock #6.2-568
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
10.4 x 6.4 x 5.8 CM (cabinet)
price: $880
new year 2021

A choice old Yaogangxian specimen with fantastic contrast. Purple phantom Fluorites in a cluster set like jewels on matrix, the largest crystal about 2.5 CM diameter. Transparent to translucent Fluorites with a glassy to waxy luster, these look fine from just about any angle. In fine condition overall, by naked eye there is no visible damage, just some minor rough spots. With a good loupe some small bruises are seen, this is not distracting and is lost in the bigger context. The color ranges from the "grape purple" phantoms to a lighter violet-blue in the crystal bodies, glows great if backlit. This is 2006 vintage, from the "golden years" for Fluorites at Yaogangxian.

Siderite on Fluorite with Chalcopyrite, Sphalerite etc.
stock #AX-15-205
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
6.3 x 4.8 x 3.8 CM (cabinet)
price: $380
new year 2021

A fine Yaogangxian multi-specie specimen hosting a prominent Siderite crystal perched on sparkling purple Fluorites. In excellent condition, we do not see much good Siderite from this famed locale that is better known for world class Fluorites and Sulfides. There are small crystals of several other species present as well as is typical from this locality, a comprehensive label can get quite long! Ex Shields and Frances Flynn collection, an excellent example of the specie from this iconic locale.
