Large, lustrous and translucent ISOLATED medium-brown poldervaartite crystals to 1.0 cm with sparkly, transparent calcite crystals on matrix from the 2001 find at the Wessels Mine. Isolated crystals are nearly unheard of! They almost always come as aggregates. Very choice material. 8.7 x 3.7 x 2.5 cm
