Wulfenite - Kuruktag Mountains, Xinjiang Uygur, China
 
 Highly aesthetic free-standing wulfenite specimen from the Kuruktag Mountains in China. The cluster of thin wulfenite presents itself as if framed by the crystals at the edge of the piece that are completely covered with calcite. The partly dark gray calcite represents an intense contrast to the orange of the wulfenite and makes it all the more visible.
