Tsumeb is the king of mimetite, by all regards, and this is a rare style of robust, deeply colored crystal. Most mimetite from Tsumeb of size has flat (pinacoidal) terminations but these come to sharp points. It is a very, very special and notable competition-level thumbnail specimen of impeccable quality. It has the color and saturation of a legrandite, combined with luster like glass! From the former collection of Joseph Freilich (who assembled a second collection of fine miniatures and thumbnails in his later life, after a forced bankruptcy/liquidation sale of his famous collection of larger specimens in the early 2000s).
