A combination plate from Guanajuato, Mexico of white, plumose sprays of calcite attractively scatttered with sparkly pyrite-dusted, medium-luster, prismatic, cogwheel-looking, gray galena crystals on a matrix of tiny gray needle quartz crystals. A fine sulfide combo piece, for which the Guanajuato mines are famous for.
