SOLD Bournonite cogswheel
stock #SOLD 6.2-891
Yaogangxian Mine, Yizhang County
Hunan Province, China
3.4 x 2.6 CM (small miniature/ large thumbnail (toenail))
price: $0


We have all seen a lot of Bournonite from Yaoganxian, some is world class, but most has a lot of serious damage. Clean examples of this brittle mineralare quite rare, and to find a nearly pristine "cogswheel" type that is crystalized all around (floater) is very special. This complex cluster has excellent mirror bright metallic luster, great form and esthetics. Very careful examination shows a few hard to find chips all under 1 mm in size, not distracting at all. For some reason, there have been more single, prismatic type crystals from Yaogangxian, this example looks much more English than Chinese! Super reasonable !
Ferberite with Fluorite and Muscovite
stock #6.2-883
Yaogangxian Mine, Yizhang County
Hunan Province, China
5.8 x 3.6 CM (small cabinet/ large miniature)
price: $450


A superb and esthetic Yaoganxian combo piece! The ferberites are razor sharp, super lusterous and undamaged perfectly perched on gemmy glasslike purple fluorite and balls of well crystalized muscovite. Other than a corner cleave on one fluorite on the outer edge of the right side, this is pristine. For such delicate and slender crystals this is a rarity and certainly of competition caliber. The Ferberite looks a lot like more azurite at a glance it is so lusterous with the uncommon tabular habit.
Bournonite on Quartz and Fluorite
stock #6.2-997
Yaogangxian Mine, Yizhang County
Hunan Province, China
8.5 x 7 CM (cabinet)
price: $1950


A very large, lustrous cogwheel type Bournonite (over 5 CM across) that is complete sitting on Fluorite and Quartz crystals one of which penetrates the Bournonite. A exceptional example from Yaogangxian, recognized as the worlds best location for this specie. Some of the fluorite and quartz have damage especially at the edges of the piece, but overall the condition is superb. This sits upright and perfectly without assistance, and the esthetics are top shelf. Given the fragility of large bournonite, the quality and completeness of this crystal is even more remarkable. Add the Fluorite for a color accent (and an uncommon association) the whole is highly desirable.
Bournonite on Fluorite with Quartz, Boulangerite etc.
stock #6.2-491
Yaogangxian Mine, Yizhang County
Hunan Province, China
8.3 X 4.7 CM (cabinet)
price: $400


A wonderful esthetic for a dark mineral like Bournonite is to be displayed on on colorful matix, and this piece does that well. Several sharp, prismatic and lustrous silvery crystals of Bournonite are well placed on a sparkling purple fluorite and quartz mixture. A few matted hairs of Boulangerite are in evidence as well. There is one Bournonite that is broken off (not very distracting tho) all the rest are quite clean by eye and only show some edge chips at 10X magnification. A very good matrix Yaoganxian piece and a good value.
Bournonite
stock #6.2-893
Yaogangxian Mine, Yizhang County
Hunan Province, China
3.5x3 CM (small miniature)
price: $160


Very bright, metalic and with fine luster, this bournonite miniature shows excellent form with a pleasing contast to the matrix. Much better than usual condition for this delicate, brittle mineral, however there is some chipping and contacting like all of these have. The main crystal shows a fantastic cogswheel form. Since well crystalized Bournonite is very uncommon, the better Chinese examples are already becoming classics. For now, this is a bargain!
Bournonite with Fluorite
stock #7 -CNA-442
Yaogangxian Mine, Yizhang County
Hunan Province, China
5x3.2 CM (miniature)
price: $650


An exceptionally large metallic crystal, sharp, lusterous and with fine termination. As a bonus it is sprinkled with lotss of small light violet fluorites for an extra sparkle. In very good condition overall though there are some small spots of damage that are very forgivable in a crystal of this size and can be minimized with careful display. This is FAR better than average and really shines!
Stannite on Quartz and Muscovite
stock #7-CNA-571
Yaogangxian Mine, Yizhang County
Hunan Province, China
7.4x5 CM (cabinet)
price: $975


The main Stannite is over 2CM, and has exceptional form, luster and is sharp and complete with stacked growth "towers" on the apexes of the crystal. For this rare specie this is a huge crystal with remarkable shape, much better than the usual globular masses without distinct faces. Overall esthetics and condition are fantastic for this usually nondescript mineral. The color ranges from silver black to a brassy golden depending on the angle of illumination. Yaogangzian Stannites are the best in the world, redefining the species, this is a very fine example.
