Distinctive cluster of four extremely well-formed radial clusters of the tan variety of Poldevaartite on a nice contrasting matrix of massive Hausmannite. The Poldevaartite balls, which range up to an amazing 2.4 cm, have a superb luster. Most of the radiating crystals have flat square lustrous terminations, which serve to create the surfaces of the balls.
