Galenobismutite on Quartz
stock #AX-15-145
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
6.4 x 5 x 3.9 CM (small cabinet/ large miniature)
price: $2500


A very fine rarity from Yaoganxian, this is a rich, significant and esthetic Galenobismutite. It is the most attractive specimen of the specie that I have seen. Ex Shields Flynn collection, obtained from Bert Ottens some years ago who confirmed the specie, this is superb from this famous classic location. This visually looks much like a fine Boulangerite and would be an excellent specimen of that but the analysis shows this to be much more rare. It seems that there may be other specimens labeled as Boulangerite that are Galenobismutite. The matrix is a cluster of clear Quartz crystals showing two generations. The metallic needle crystals are in large masses on several faces of the specimen and are also included inside the largest, earlier Quartz prisms. In excellent condition. Mindat lists Galenobismutite from Yaogangxian but there is not yet a single photo from there.

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


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.

Bournonite
stock #6.2-892
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
3.1 x 2.6 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $350
new year 2021

A super bright "gun metal" luster Bournonite crystal which is doubly terminated. Some of the faces are perfectly smooth mirror-like while other are striated. From the Yaogangxian Mine which had the reputation for providing more fine Bournonite than the rest of the world's localities together. Before these finds this was a rather rare and sought after specie. There seems to be no twinning on this crystal which is unusual for Bournonite which is almost always twinned. Displays well as seen, there are some small chips on the terminations and the back is contacted but not damaged. While not perfect this is far better than 99.9 percent of these, and the rough areas are not excessive. As a whole Bournonites are notoriously brittle and most often incomplete.
