Stannite on Quartz and Ferberite

TR26I1: The sample is magnificent both for its size and the quality and definition of the groups of Stannite crystals on Quartz with Ferberite. The specimen had been analyzed to confirm it is really Stannite and not Sphalerite, because on Chinese samples such confusion is possible.
The specimen has been published in the book 'China', by Berthold Ottens, on page 526
Yaogangxian Mine, Yizhang, Chenzhou Prefecture, Hunan Province China (±2000)

Specimen size: 11.2 × 9.2 × 6.7 cm = 4.41” × 3.62” × 2.64”

Sphalerite

In the Kanjianwan mine they found these excellent Sphalerites. They have very well defined crystal forms and are red (a little darker than the ones from Aliva, Spain). They are accompanied by Quartz and Galena so the overall effect is esthetic and competitive.

Hübnerite

Ferberite is often found at the Yao-gan-xian mine, so the surprise for us was to find that some of the Wolframites, as Chinese geologists had told us, are not of iron (Ferberite) but of manganese (Hübnerite). They are also very pure (almost all manganese and very little iron).
As we often do with novelties, we will send the client that buys one a copy of our analysis.

Phenakite with Fluorite and Orthoclase (adularia)

Front

Side

Phenakite with Fluorite and Orthoclase (adularia).

MA94X1: A novelty at Munich 2012. Phenakite is a new species for Huanggang, or at least it was not previously referenced, and we must add it to the already long list of species from this mine. The elongated Phenakite crystals that coat the entire sample are very small but show very well defined faces and edges. They are transparent and intensely bright. They are with sharp octahedral crystals of Fluorite with smaller faces of the cube. These crystals are translucent, with a very deep marine blue color and very well marked phantom growths. There are also some isolated crystals of Orthoclase (adularia variety). We’ll send a copy of the analysis of the Phenakite and the Orthoclase.
This specimen was photographed and published as a novelty at the 2012 Munich Show of the magazine ‘Mineralien Welt’ and appears on page 24 of number 1/2013
