1521004) Azurite with Malachite, Cuprite - Liufengshan Mine, Anqing-Guichi Mining District, Guichi District, Chizhou Prefecture, Anhui Province, China
Size: 16.0 x 12.0 x 7.0 cm (large cabinet)
Price: $ 32000
Since 2002 the mineral market has seen a large quantity of attractive azurite specimens from this locality in China. Most specimens consist of druses of micro azurite crystals associated with malachite. At times discernible crystals have been seen, usually measuring to about 1.0 cm in smaller specimens. The large cabinet example shown here is outstanding. Sharp lustrous deep blue sharply formed crystals of azurite to almost 2.0 cm in size are richly scattered over a 16.0 x 12.0 x 7.0 cm matrix. Small crude crystals of cuprite, these coated by green malachite, are present as well. There is no damage. The association with malachite/cuprite is somewhat reminiscent of the old Copper Queen Mine, Bisbee, Arizona specimens. In terms of crystal size, luster, perfection and size this is an exceptional Chinese azurite specimen. Ref: Liu (2006), Fine Minerals of China; pp 27-30.

1341002) Cerussite - 30th level, Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Size: 8.5 x 7.5 x 5.5 cm (small cabinet)
Price: $ 25000
The now closed classic mine at Tsumeb, Namibia is known for having produced some of the world's finest known cerussite specimens. Some of the most sought after examples are the ones showing reticulated twinning. The example shown here is superb. The specimen consists of a 8.5 x 7.5 x 5.5 cm grouping of sparkling colorless sharply formed reticulated twinned cerussite crystals with little attached matrix as seen. The specimen shows all around. Like almost all of these, there is tiny micro-chipping present on some of the crystal edges, due to the extreme delicate nature of the species. Overall I think this in wonderful condition for the species. The piece dates back to the early 1960's and was originally acquired through noted Namibian dealer Sid Pieters. Ref: Gebhard, G.

Price: $ 375
An exceptionally rare and unusual galena, this 5.0 x 5.0 x 5.0 cm cluster of flattened crystals is complete all around. Non-lustrous, due to being found so close to the surface. Good galena specimens from Iowa are seldom seen available on the mineral market. This must have been collected in the latter part of the 1800's. Overall in good condition as seen and sits nicely for display by itself. The mineralization here is associated with the Upper Mississippi Valley District around Shullsburg, WI and Galena, IL.
