An exceptional miniature. Chalcedony coats crystals of Wulfenite, capping the penultimate mineralization of sparkling Black Chalcedony which itself is dotting with tiny Vanadinite. The internal morphologies are visible in cross section thanks to the exceptionally smooth polished matrix sides. A unique elegant mineral specimen from a more civilized age.
