Description
Here we have a superb and relatively old combination piece from classic Boltsburn Mine of Rookhope in county Durham, England. A bunch of metallic, cubed Galena crystals accompanied by beige-brown, disc-shaped Siderite, cubed and gemmy, pale violet Fluorite and brassy Chalcopyrite. At both sides of the piece we easily see jet-black and multifaced Sphalerite crystals as well. The display face is almost pristine, the backside has just a matrix contact at the bottom. Great material.
