5.3 x 4.2 x 2.5 cm. This sharp octahedral crystal is of a habit rare from the mine. It is about 2 cm across and is pristine, free-floating into the air as if about to jump off the quartz (the quartz cluster is also complete all around).
2.5 x 1.9 x 1.8 cm. A fine thumbnail. It has riveting perfection and total transparency. The crystal is just over 1 cm and is rimmed on one side with sparkling pyrite. The fluorite is perched at the apex of the host quartz. Complete-all-around.
5.4 x 2.7 x 2.5 cm. A sharp, purple and blue cored phantom crystal measuring 2 cm, perched on a quartz point. Note the rare, acicular crystals of stibnite included inside.
5.0 x 4.3 x 2.3 cm. A fine gem crystal hanging off the quartz, as if a fruit ready to drop off the tree. It has riveting perfection and total transparency. The crystal is just over 1 cm and is rimmed on one side with sparkling calcite crystals in the form of paper-thin discs. The calcite also coats the back of the quartz. Complete-all-around.
4.4 x 2.0 x 1.7 cm. A fine specimen with a 1.25-cm purple cube, modified on its corners, perched at the apex of the quartz termination.
2.8 x 2.3 x 1.7 cm. Two fine, deep purple fluorites like twin heads atop a natural pedestal, making for a very pristine and aesthetic thumbnail.
2.5 x 2.5 x 1.8 cm. A beautiful crystal with intense purple color, really intense for this particular mine. It is sharp, complete, and wonderfully terminated with slightly beveled edges. The crystal measures 1.5 cm and is perched on quartz.
5.0 x 3.7 x 3.0 cm. This fine crystal measures 2.3 cm on longest edge and is perfect all around, hanging off a bit of matrix and so exposed more than usual for a cubic crystal on matrix. It is subtly phantomed with purple cores in green outer layers. The crystal, along with an associated quartz crystal, is perched in muscovite matrix which forms a nice natural knoll. It is complete-all-around. Minute chalcopyrite (?) inclusions add a nice accent when studied close up.
6.4 x 3.8 x 3.7 cm. Beautiful, gemmy, transparent crystals to 1.7 cm are perched on matrix of quartz and yellow muscovite. It is a very colorful combination. The quartz is perfect, pristine, and the whole piece sparkles with lustre.
7.2 x 6.4 x 5.2 cm. An intense purple phantom with incredible transparency. This crystal glows with color, and is 2 cm across. It is perched on the "shoulder" of a lustrous quartz cluster.
7.0 x 5.4 x 4.3 cm. This is a very rare combination from the mine, with purple fluorite cubes to 2 cm included by acicular crystals of stibnite. It looks like silver hairs inside the fluorite. So far as I know, this is a unique association to this mine. The crystals of fluorite are perched on top and form a sharp horizon line, with great sharpness.
6.0 x 5.8 x 4.0 cm. One of the few purple fluorites to ever come out of Shangbao, it seems, this is even more rare…one of the few purples to come out in the end-2008 dolomite finds. Most of the crystals associated with the dolomite in a series of several pockets were light blues and pastel greens, with a few pinks. This features a sharply phantomed purple crystal about 2 cm across, with others, in a pristine floater cluster with quartz and sparkling pyrite. Overall, a striking combination and quite unique for the locality.
7.7 x 6.0 x 5.9 cm. A huge 6-cm crystal, very nicely colored a pastel blue with phantoms, perched on quartz and a bit of matrix. The fluorite is beautiful for its color and its unusual elongation. It is very gemmy, so that you can look deep down into it. In person it is extremely 3-dimensional.
10.0 x 6.7 x 4.3 cm. An unusual specimen from a find several years ago, with intense green fluorite - a single cuboctahedron that looks like it was sprinkled with sugar. It is nested in a thin plate of brilliantly sparkling quartz, with ivy-like growths of quartz that invest the fluorite in 2 places. A fine specimen from an unusual find at this less productive mine.
6.2 x 4.2 x 5.3 cm. This piece features a solid pedestal of fluorite with a single larger crystal atop, nicely decorated with a sugary coating of quartz on one side, and fat milky crystals on the other, with the green fluorite popping up in between. Unusual.
