An EXCELLENT, OLD-TIME and UNCOMMON Tsumeb specimen from the Rob Smith Collection. Lustrous, sharp and hexgonal, tan mimetite crystals to 1.8 cm RICHLY and attractively cover the 3-dimensional matrix. The mimetite crystals are preferentially coated with lustrous, gray smithsonite microcrystals. The matrix of this very fine piece is botryoidal green and massive blue-gray willemite! This is an old specimen, from the upper levels of this famous and now-closed mine. This is a hefty zinc and lead specimen, for its size, at 398 grams or 7/8 of a pound! Essentially pristine, with only a trivial bit of periphery bruising. An important, old-time combination specimen.
