Very pretty large cabinet piece showing semi lustrous disc-shaped crystals of calcite is largest 6.0 cm across dusted beautifully with deep red hematite. Very sparse in light micro-chipping present, I think considering what this is it is in terrific condition. Displays beautifully on a custom acrylic display base. Measures 20.0 x 17.0 x 7.0 cm. Classic Tsumeb material. Ex Marshall Sussman collection.
