A rather unusual large plate of bournonite crystals, all showing sharp UNTWINNED crystals to 2.25 cm in size. This is actually more uncommon, compared to the twinne dform of the mineral. The crystals form this locality are sharp and gun-metal lustrous, making for very dramatic bournonites. The matrix contrasts a bit more in person than it appears, and is coated with sparkly druse of other sulfides such as pyrite. This is a rich, large, unrepaired piece of high quality from the amazing finds here of several years ago.
