This piece is largely covered with quartz crystals of two generations. The larger crystals are the first generation, then well formed bournonite crystals formed on the quartz, followed by a fine drusy quartz which drapes over some of the bournonite crystals. Nice cogwheel-twinned bournonite crystals!
