Several well formed textbook sharp Kesterites are well displayed on the contrasting Muscovite (which is also well crystallized). For a few years the Mt Xuebaoding area produced the worlds best Kesterites usually coated with green Mushingtonite. The mining sites have closed and shifted and there is no more. The only source now for a good piece is from an old collection. This piece has sharp crystals up to 1.4 CM though most are smaller. Scattered sprays and balls of Malachite are also present, this was a less common accessory mineral at this find. In fine shape this could be trimmed to several thumbnails or miniatures but is also choice just as it is. A good value for a modern classic now getting quite rare.
