Smoky quartz - Malosa mount, Zomba, Malawi

A crystallized plate of shiny smoky quartz, some of them biterminated, arranged in preferential directions that may remind one of Japanese macerations (= La Gardette's macerate), but which correspond in fact to an epitaxial growth with feldspars that were then dissolved (some remains are still present). This type of quartz called gitter quartz" is quite rare ("gitter" in German meaning "grid"). Known from the Erongo Mountains in Namibia, this one comes from Mount Malosa in Malawi from where only a few hundred pieces, mostly small, were extracted in 2014/2015. Some fine arfvedsonite crystals are present, especially on the back. The plate is in very good condition (very little damage considering the size and number of crystals). We found it interesting to leave the feldspar between the quartz crystals, but further cleaning could be done upon request and at no extra cost."
