Outstanding and beautiful feathers of spinel-twinned native Silver crystals nicely growing on dark native Arsenic matrix from the famous locality of Pohla, Germany. The Silver has striking herringbone-patterned elongated twinned crystals growing all over the base. They are bright, perfect and contrast strongly on the black background. The specimen is mined in 1989. In very good condition - some contacts. On acrylic base.

Exceptional!
