An unusually attractive specimen with very metallic calaverite crystals laying flat amongst rolling quartz druse, and so not etched or cleaved out of surrounding matrix as you usually see for this material. Rather, the natural matrix surface is the host for embedded calaverite crystals of unusual thick and platy form, looking more solid and robust like andorite than normal wispy calaverite! The cluster of aggregate crystals is about 1.4 x 1 cm across. RARE WITH MINE ATTRIBUTION on old Ward's Science Establishment label!
