Sphalerite on Quartz
Shuikoushan Lead Zinc Mine, Changning, Hengyang Pref.
13 x 10.6 (cabinet)
Deep red complex crystals of Sphalerite sit on a plate of sparkling reddish quartz. Some are claiming the quartz is red due to inclusions of Sphalerite, I am not sure about that. There is galena here too and the back of the piece is crystalized calcite. The largest crystal is 3.3 cm and with good backlight it glows a rich red. No damage and great luster, this looks like globs of jelly on matrix. Way above average!!
Xianghualing Mine, Linwu County, Chenzhou Pref.
13 x 11 CM (cabinet)
The large octahedron here is over 7 CM, undamaged, lustrous and aesthetically perched with others on a contrasting matrix . The crystals all show the "micro stepping" being composed of hundreds of tiny fluorite crystals that are arranged together in the octahedra. A deep green that can backlight well, this piece is a very fine example of an older style of Fluorite from Xianghualing not often available anymore.
4.5x3.9 CM (miniature)
Sharp and glassy Euclase on matrix to 1.4 CM. A great example from this small one time find. These were the best Chinese examples of this rare Berylium gem mineral. The crystals have some micro cavities on a few faces with unknown black materials inside. Good condition in general, there are broken and damaged crystals on the edges and back the display side looks fine to the unaided eye.
Bournonite with Fluorite
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
5 x 3.2 CM (miniature)
An exceptionally large metallic crystal, sharp, lustrous and with fine termination. As a bonus it is sprinkled with lots 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!
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. Yaogangxian Stannites are the best in the world, redefining the species, this is a very fine example.
Himalaya Mine, Gem Hill,Mesa Grande District, San Diego County
4.6x2.4 CM (miniature)
A richly zoned crystal that is very sharp and damage free. This is the classic bicolor for this mine showing a sharp flat termination. It has much richer than usual color depth and really glows with any backlight.

Changmenshan Copper Mine, Jiulang
12.4 X 11 CM (cabinet)
A very large and striking example of this find, this ball like cluster has distinct and sharp crystals of Azurite reaching 2 CM with deep blue color. This is less "rose like" than some other examples and more a spherical aggregate of blocky crystals. There is minimal damage (some very small bruises not immediately seen and not in the better display areas) but the overall impact is very strong. One of the very best we have seen from this mine.
Changmenshan Copper Mine, Jiulang
8.5x8.5 CM (cabinet)
A very well developed almost spherical aggregate of blocky azurite crystals up to 1.4 CM and some smaller flattened rhomb forms. This piece is also encrusted with many lemon yellow micro crystals of an unknown mineral (awaiting analysis we will send results if you wish). Quite attractive and a good value.
