An nice older Chinese specimen of the dark transparent Cassiterites from Ximeng that are now very uncommon. These lustrous crystals on contrasting matrix show both twinned and untwinned forms. These are a dark brown to almost golden on some edges and are prettier in person. This find was unlike any other Cassiterites found in China, being more similar to the best from Bolivia, yet still recognizably different.
A small but very clear perfect Tourmaline with a dark termination. We see very few good Chinese gem Elbaite and few of those with this color. In fine condition the matrix is another Elbaite crystal that is contacted with a little feldspar, but is also undamaged. Tghis is also a dichroic crystal so the color can shift from a more yellow to more green hue. A nice thumbnail from an unusual locale.
Cassiterite on Quartz
Amo Mine, Ximeng
3.8 x3.4 x 2.2 CM (miniature)
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.
Veszelyite on Hemimorphite
Gejiu Ore Field, Gejiou ounty, Honghe Prefecture
10.2 x 7 x 5.7 CM (cabinet)
A large blue Hemimorphite in botryoidal form hosts dozens of brilliant blue Veszelyite crystals. Ex Shileds Flynn collection, a very esthetic presentation for this rare mineral. This comes from an important find in Yunnan province that made big news in 2006. The specimen has been sawn on the back/ underside but the display faces are natural in form. The Hemimorphite has a very three dimensional form, and this also has a range of blue hues that add to the relief.
Deep purple color Flourite cubes in a chain arrangement. From the recent find of stacked or stalactitic Fluorites which had originally formed over Stibnite crystals that no longer present. Some edges have an epitaxial coating of Barite that makes a nice contrast. In fine condition and very esthetic. This was a very small find and few had this intense color.
An exceptionally esthetic botryoidal growth of Hemimorphite with a rich blue-green color. Looks a lot like a Smithsonite. This is in undamaged condition, has perfect wet-look luster and a coating of micro clear Hemimorphite crystals to add a little sparkle. Wenshan has become a world class producer of Hemimorphite but this habit is not at all typical, a very choice miniature.
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.
An attractive, delicate and rich color Gibbsite is host to dozens of sharp Wulfenite crystals. This is the only specimen of this rare association that I have ever seen. Ex. Shields Flynn collection which he obtained from Bert Ottens. In perfect condition, this would be a really fine Gibbsite even without the Wulfenites. Displays well from many angles. Choice!
