Kësterite,
Mushistonite, Beryl (variety Aquamarine), Malachite, Stibnite(?),
Quartz,
and Muscovite Mt Xuebaoding, Pingwu County, Sichuan Province, China 28.0 x 11.3 x 10.1 cm (11.0 x 4.4 x 4.0 inches) Specimen status: Sold A large, complexly terminated quartz
crystal hosts a plethora of other minerals. especially notable are
several complete crystals of the rare copper tin sulfide mineral kësterite;
the largest of these is 9 mm across and coated with a layer
mushistonite, a rare green tin hydroxide . Also present are a few
delicate blue, glassy aquamarine crystals, reaching 1.5 cm along the
edge. Minor but deep green malachite is present with some
kësterite in one pocket. Muscovite is also scattered about. And as
if all this wasn't enough, the quartz features a few stibnite
inclusions. (Mindat list boulangerite but not stibnite from this
locality; to my eye this looks more like stibnite.) This specimen has
been nicknamed Atlantis, after its resemblance to the space shuttle
which recently completed the final shuttle mission. An impressive
association specimen that has several display possibilities and is free
of significant damage.

case.
