Very well formed single multi-faced crystal of Wulfenite sits at the center of the specimen from the Pure Potential Mine, Arizona, USA. The Wulfenite crystal measures to 1cm, with a translucent orange-red colour., on a contrasting dark matrix of inter grown rhombs of Calcite. Some of the Calcite crystals are partly covered in a druse of orange Vanadinite. A pleasing Wulfenite from a mine once worked for specimens.
