Item Description

A classic, superb specimen of highly lustrous and translucent, shimmering tan-colored siderite rhombs (flattenned so they look like discs) in an arborescent cluster - this is a darned good old siderite, on its own merit! These specimens, of a very characteristic style and habit, were found in the 1960s at this famous gold mine. The edges are festooned with small brassy, tabular crystals of both cubanite (more erratically formed or acicular xls) and pyrrhotite (sharply hexagonal). The larger hexagonal crystal of pyrrhotite (about 1 cm), however, just sitting there on a perch like it is about to blast off, is special and almost unheard of for this locale. Valued $750
