Metazeunerite, Quartz Locality: Erongo Mountain, Usakos and Omaruru Districts, Erongo Region, Namibia (Locality at mindat.org) Size: miniature, 3.4 x 2.8 x 2.0 cm Metazeunerite on Smoky Quartz At the Munich show, a part of Namibian collector Heini Soltau's collection of Erongo material was privately being sold off, and among that lot were three remarkable, absolutely mesmerizing specimens to me...sharp crystals of zeunerite to 7mm perched on complete smoky quartz crystals. They come from a small pocket found in 2003 in granite , East of Tubussis (see NAMIBIA book, page 650). This specimen is infact ILLUSTRATED in the magnum opus NAMIBIA book which cam out last year in Germany (page 650, bottom). I think this was the best one for sale, and I was happy to get it. I understand that only a handful, perhaps less than a dozen specimens, came from this onetime pocket. This is a choice miniature of display quality for the species or for any Erongo suite. It can be displayed either vertically or as shown, though I prefer the crystals atop myself. Mineral

Inyoite, Meyerhofferite Locality: Monte Azul deposit, Sijes, Salta, Argentina (Locality at mindat.org) Size: 5.7 x 4.1 x 3.1 cm. A razor-sharp crystal, to 3.5 cm on edge, and extremely impressive in person! One of my favorite miniatures here, this one LOOKS like it has a different crystal form almost, because of the sharp angular nature of its rhombohedral crystals, elongated steeply in one direction. A few gemmy, discrete Meyerhofferite crystals are included inside. Mineral
