SOLD Elbaite on Feldspar
stock #SOLD 9.1-370
Gaoligong Shan, Baoshan Prefecture
7 x 5.1 x 4.3 CM (cabinet)
Early summer 2023
An unusual and attractive Chinese Tourmaline with bright pink to reddish crystals covering Feldspar and a little Quartz. This is from a find in 2003 in the Gaoligong Mountains of Yunnan province. At the time of this find there was great excitement in the hopes there would be much more to be found, but there was not. We have not seen anything new since. These crystals are very lustrous, sharp and translucent, jumbled in a dense cluster, these are up to 1.1 CM though most are smaller. A pretty and affordable Tourmaline from a little seen locality.
A huge, stout main crystal of Magnetite 7.8 CM tall dominates this very unusual early specimen. Other Magnetites up to 2.8 CM are on the matrix as well. We obtained this specimen in China in 2004, it was quickly sold back then but it is back now to be recycled to a good home. This is by far the largest Magnetite I know of from China, it was from a very small lot from the pegmatites of the Gaoligong Shan, and has a form and style unlike any of the later finds in Inner Mongolia and elsewhere. The crystals are all thick yet elongated and show stepped faces on all sides. Somewhat crude but still quite sharp, complete and showing textbook form. Aside from a single contact on the back area of the main crystal this is in perfect condition. These crystal faces all show a slightly golden lustrous alteration coating that adds a glistening to the overall appearance. Despite looking, I have never found any other Magnetites from this region for sale over the past 17 years. A nice Magnetite from anyplace but a really great piece for any serious China suite.
Deep, vivid color Fluorite cubes are arranged in elongated chained structures having formed over crystals of Stibnite that are now gone. The hollow spaces left by the Stibnite are seen only on the back of the specimen. On the backside the Fluorites are coated with tiny white Calcite crystals. This specimen was illustrated in two mineral publications and in the "Whats new in St Marie" video production. This was a very exciting small find a few years ago but now these are no longer being found. Striking color and wonderful form, a different sort of Fluorite that is a choice addition to any good Suite.
Topaz on Quartz and Clevelandite
Wenshan County, Wenshan Autonomous Prefecture
7.8 x 6.4 x 4.7 CM (cabinet)
new year 2021
Several Quartz crystals are clustered around a single gemmy Topaz crystal set on Clevelandite. The Topaz has some lightly frosted faces and others are glass clear, transparent and very lustrous. The color is a light sherry hue that looks slightly pinkish in some light. From finds in 2004 in Yunnan Province in China, we have not seen such good pegmatite minerals from this region for several years. In good condition overall as seen there is a crack in the Topaz and a chip is noted on one face that is not very evident or distracting. A really choice Chinese Topaz.
From a find about 12 years ago in Yunnan Province, China. Pink Tourmalines with redder caps that came from the pegmatites of Gaoligong Shan is what seems to have been a mix of Elbaite and Liddiacoatite perhaps in zones. This piece shows the typical morphology of the find and has a nice bubble-gum color. The outer edges have contacts and chipping but there are several complete terminated crystals with no damage, the largest being 1 cm tall.
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.
