MIMETITE

This small cabinet specimen is a splendid example from the Tsumeb mine in Namibia; a mine famous for its high quality Mimetite.  This particular specimen from 28 Level,  is incredibly rich, for even the majority of the matrix appears to be composed of finely-crystallised and intergrown Mimetite crystals.  Essentially, a Mimetite-filled vein, up to 2.5 cm wide, traverses the specimen and grades from white-frosted, pale lemon colloform sprays, through glassy acid-lemon divergent sprays (to 8 mm across) and then an open vug lined and bridged with double-terminated,  gemmy, glassy-yellow acicular Mimetite crystals sprinkled with microspheres of pale emerald-green Malachite.  The base of the specimen also has many shallow vugs completely lined with gemmy acicular Mimetite crystals.  A showy aesthetic specimen of Mimetite from Tsumeb which shows-off a variety of habits.
