Item #13726 Leiteite 2.2x0.3x0.1 cm Largest Crystal Size: as above $50.00 Tsumeb Namibia We don't often see this mineral for sale. Here is a cleavage fragment of leiteite.	Item #14600 Mottramite, Calcite 7.9x5.6x2.6 cm Largest Crystal Size: 1mm $45.00 Tsumeb Namibia This specimen is composed mostly of mottramite in branching forms of small crystals. A dark green colouration to the mottramite. Lots of iron tinted calcite crystals on the front of the specimen. There is significant bruising to this specimen but there are lots of good areas of mottramite crystals, as well.
Item #14595 Quartz 7.1x6.8x2.8 cm Largest Crystal Size: 1mm $40.00 Tsumeb Namibia This is "just" a quartz specimen but it is very attractive and eye-catching! It is simply a druae of tiny quartz crystals that have formed over a veneer of copper mineralization (malachite?) on the rock underneath. Some of the quartz seems almost stalactitic. Interesting and attractive.	Item #16318 Descloizite, Calcite 8.5x7.5x4.7 cm Largest Crystal Size: 10mm $175.00 Berg Aukas Grootfontein Namibia An interesting, mound of lobular aggregates of light brown descloizite. The lobes are composed of thin-bladed descloizite crystals. They are simply lustrous descloizite on one side and coated with tiny calcite crystals on the other side. Displays very well!	Item #16319 Descloizite 6.3x5.7x3.6 cm Largest Crystal Size: 16mm $85.00 Grootfontein Namibia A cluster of very large, to 16mm, crystals of rich, lustrous, brown descloizite from THE classic locality.	Item #19880 Wulfenite, Tennantite 6.0x4.1x3.0 cm Largest Crystal Size: w-5mm $35.00 Tsumeb Otavi Namibia Here is an interesting association. The main specimen is rounded, blackened tennantite crystals like we often see from Tsumeb. In addition, though, there are several sharp, tabular, lustrous wulfenite crystals on the tennantite. The bigger wulfenites are chipped but the smaller ones are very sharp and nice. Tsumeb never gets boring!!
