A beautiful cabinet specimen of a glassy, highly lustrous, translucent, black quartz crystal accompanied by smaller crystals on one side. The crystals are di-pyramidal with no prism faces and are called morion quartz by some people (I know not why) and beta quartz by others on the market. This is old material from a few famous finds in Brazil. These are high temperature quartz crystals, technically quartz ps. after beta quartz (see MINDAT for a further explanation under "Quartz-beta" at http://www.mindat.org/min-7395.html). The fine, large, complete-all-around crystal is very nearly pristine. Older material from the Richard Hauck Quartz Collection; and hails from an uncommon Brazilian locality - the Recruta Farm, Vitoria da Conquista, Bahia.
