A historic, interesting, and beautiful combination piece from Tsumeb featuring Mimetite as gem crystals on Smithsonite! Numerous, isolated and grouped botryoids of creamy colored Smithsonite cover the front and back of this piece with sparkle contrast to the hundreds of tiny, glistening, yellow prismatic crystals of Mimetite. A very unusual combination dating back to the first oxidation zone, early 1900's! This piece was in an East Coast mineral auction in 1908 (the label of $3.00 dates to 1908, and this format was seen on all the old specimens which came down to me through Belsky with his notes on the previous auction). The core of that collection (whose name is now lost) was sold to another collector and later was passed on as part of the Howard Belsky collection which we purchased some years back.
