Post Tucson 2022

A large, complex crystal of Sphalerite with a "crown" of clear Quartz crystals. This is a rather old specimen from a find in China in 2003 at the Rucheng Mine which is very close to the larger Shuikoushan operation and I am told may now be linked to it underground. The Sphalerites found at both these localities are of great importance and are impressive. The Rucheng area was noted for larger and often complex crystals like this with sizable Quartz where the Shuikoushan operations had smaller Sphalerites, lighter red color and druzy Quartz. This Sphalerite is dense and opaque except at the very outer thin edge. It is a deep brown color with some red and yellow highlights in spots and a small amount of Chalcopyrite as well. In good condition, there is no obvious damage but a few small rub points can be found, the Quartz is contacted in the back. We've seen nothing new from this locality for a few years and the mine has been idle for a while.

Galena on Quartz
stock #AX-15-146-(C100)
Rucheng Mine, Caojia, Nuanshui, Chenzhou
Hunan Province, China
8.6 x 6.4 x 3 CM (cabinet)
price: $360
Early summer 2021

With all the great Lead minerals that are found in China it is surprising how uncommon are good specimens of Galena, the most common lead mineral. This is a nice Galena from anyplace and super fine from China, with two textbook perfect crystals on a bed of milky Quartz. Ex Shields Flynn collection, obtained from Bert Ottens, this is a 2004 vintage specimen with the largest crystal 2.6 CM across. The two crystals are both of different habits, perfect and undamaged. The Rucheng Mine is famed for the fine Sphalerites it produced about 15 years ago. This piece is about as fine as Galena is ever seen in China.

Sphalerite - gemmy
stock #18.1-221
Rucheng Mine, Caojia, Nuanshui, Chenzhou
Hunan Province, China
7.9 x 6.8 x 2.9 CM (cabinet)
price: $650
Worldwide mix summer

A nearly pure plate of large crystals up to 3CM across that are transparent in many areas and have a rich dark red hue. A single Quartz crystal on one edge is the only non Sphalerite part of this specimen, there is no matrix. In very clean condition, all the crystals on the display side are undamaged, contacted on back only. From the famed finds made in the 2000-2005 era in Hunan province. These localities are all closed now and specimens have become quite rare on the market in this fine quality.

11 x 7.9 x 6.4 CM (cabinet)

Spring update

A giant Sphalerite crystal stands on a mix of Quartz crystals and Sphalerite. Bright luster, translucent and in fine condition, a dramatic specimen. The complex faces in some photos can seem like bruises were light reflects off many facets, but this is clearly pristine when seen in person. From finds in 2002-3 at Rucheng Mine, at that time the locality of was given as Shuikoushan which is a Zinc mine nearby, but that was purposely misleading. While some large Sphalerites did come from both localities, this habit is was unique to Rucheng. These places are no longer mined and big crystals like this are long gone. A modern Chinese classic and a really impressive Sphalerite, cleaves on the backside but undamaged front, visually perfect on display.
