Cassiterite -huge for locale, with Ferberite, Arsenopyrite, Chalcopyrite, Quartz, Muscovite, Stannite, Fluorite etc.
stock #18-AX-29-046
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.8 x 4 x 2.8 CM (miniature)
price: $1600
Late Summer 2018

The very best Yaogangxian Cassiterite I have ever seen, with the largest crystals as well. An excellent multi-specie piece mostly composed of superb Cassiterite. This locale has produced thousands of excellent mineral specimens but Cassiterite is very rare from this famed locale. Sharp lustrous crystals to almost 3 CM are arranged in a radiating cluster on a very complex matrix. I count at least 7 mineral species on this miniature, but the Cassiterite is clearly dominant and is in fine condition as well. A superb modern classic and a very important Yaoganxian specimen.
Cassiterite on Quartz
stock #18AX-12-417
Amo Mine, Ximeng
Yunnan, China
3.8 x3.4 x 2.2 CM (miniature)
price: $440
Late Summer 2018

Cassiterites in gemmy crystals with brilliant luster and sharp form. The Amo mine in Ximeng county (Yunnan, China) produced a few spectacular Cassiterites. They were immediately prized and have almost disappeared. Unlike from any other location, these had a unique, recognizable style that could be very esthetic. This fine example is sharp, well formed, nicely perched on a cluster of quartz crystals that have some green inclusions as a bonus. In great condition there is contacting only on the back side not in view. In some photos what may look like damage is internal reflections inside the Cassiterites. Much better in person.
Topaz with Cassiterite and Apatite- Vintage specimen
stock #15.1-987-SM-2690
Ehrenfriedersdorf, Erzgebirge
Saxony, Germany
7.3 x 6.3 x 4 CM (cabinet)
price: $1200
Spring update

An old Saxony specimen with several lustrous Cassiterites to 2 CM mixed with a hundreds of small, gemmy Topaz crystals and Apatites as well. Ex Charles Noll Collection, with a very esthetic addition of what seems to be rich green Allophane encrusting both species. I have only seen one other similar old specimen (19th century vintage). Vintage label included. In very good condition, some minor chipping seen only with magnification. Crystallized on all sides.
Cassiterite variety Needle Tin
stock #18.1-104
Minera Monserrat, Challapampa, Poopo Province
Oruro Department, Bolivia
5.6 x 5.5 x 3.4 CM (cabinet)
price: $160
Spring update

A very unusual specimen from Boliva that looks like an old Cornish "needle tin". A three dimensional matrix densely covered with delicate accicular crystals of brown Cassiterite. In fine condition as seen, ex. Hitchings collection. Especially impressive under magnification, this is an uncommon habit and a well crystallized example.
Cassiterite on Muscovite
stock #8.1-010
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
6.3 x 5.2 X 3.8 CM (cabinet)
price: $420
Spring 2017

Incredibly lustrous, super, sharp Cassiterite twin crystal set nicely on contrasting Muscovite matrix. The Cassiterite is 1.8 CM in diameter and has no damage or chipping even under 20X magnification. From finds in 2003 at Mt Xuebaoding, this quality of Cassiterite is simply not being found anymore. High esthetics and display impact for a small size specimen.
Cassiterite on Quartz w. Chlorite
stock #8.1-086
Gaoligong Shan, Baoshan Prefecture
Yunnan, China
4.7 x 4.5 x 3.5 CM (miniature)
price: $280
Spring 2017

A nice Cassiterite is perched atop a quartz crystal matrix. Dark opaque black with good luster the condition is very good but there is some chipping on the front and contacts on the backside (not seen on display) From the unusual locale at Gaoligong Shan, a well developed Cassiterite.
Cassiterite with Arsenopyrite and Muscovite -unusual locale
stock #Alec-12-135
Yaogangxian Mine, Yizhang County
Hunan Province, China
3.6 x 3.5 x 2 CM (miniature)
price: $100
Winter 2016-17

A rare example of a Yaoganxian Cassiterite that is well crystallized. One of the most prolific mineral mines on Earth, Yaoganxian has produced many fine specimens of many species, but almost no Cassiterite. This small specimen is the best example we have seen. There are a few small Arsenopyrite crystals as well and this has some well defined twins. Compared with the world class Cassiterites from the famed Pingwu and Ximeng mines this is a modest piece, but for a Yaoganxian suite this is a killer.
Cassiterite
stock #ALEC-12-213
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
3.8 x 3.3 x 2.9 CM (miniature)
price: $150
pre Tucson 2015 update

There have been many Cassiterites recovered from Xuebaoding, but the prismatic type with the pyrimidal termination is by far the rarest form. This is a good lustrous single crystal that shows the habit well. There are contacts and a few tiny chips so the price reflects this yet it is still a very nice example.
