Quartz var. Amethyst with Prehnite and minor Calcites too.. Exceptional internal prismatic quality, containing a precise colour zone phantom of both Amethyst and Smoky Quartz. Perfect condition.
The exterior surfaces show fantastic growth-interference - some of the best I have ever seen - from both piperspatt Calcite and also most notably, from large Prehnite crystals. Growth interference is where a crystal type leaves it's own distinct growth marking on a totally different type of crystal, having grown attached together and then, upon parting this is revealed.
The mining area known as Brandberg (Fire/Burnt Mountain) is in the Goboboseb area of Namibia. Not too far from the blisteringly hot 'Skeleton Coast', the area is hot and dry and rather inaccessible, making mining conditions very tough. Crystal specimens are becoming increasingly hard to find; miners chisel away at the hard basalt rock, sometimes for weeks, before finding a pocket, which may yield only a few crystals.
