Kermesite

A superb array of lustrous, radial and fan-like Kermesite crystals laying flat against and covering the display surface of a dark grey Stibnite veinstone matrix. This magnificent small cabinet specimen is from the classic Slovakian location at Pezinok in Pezinok County and is possibly from the Nová Alexander adit. Long acicular, deep maroon red crystals of Kermesite measuring to 2 cm display blood-red reflections when strongly-lit and cover a shallow druse of Calcite crystals. The Kermesite, an antimony oxysulphide, has a bright metallic lustre and contrasts well with the dusting of scattered small Calcite crystals. This specimen is accompanied with a previous collector’s label.
