Stibnite

Bright metallic silvery-grey prismatic crystals of Stibnite invest a white Quartz matrix with many Stibnite crystals spanning across cavities in the Quartz. This excellent cabinet specimen is from the Kremnica mining district in Žiar nad Hronom County, Slovakia, a picturesque region and host to almost 130 mineral species. The Stibnite, an antimony sulphide, covers most of the display face in an array of randomly orientated acicular crystals up to about 2.4 cm long. The narrower, longer crystals have a bright silver metallic lustre while the broader, more stubby crystals tend to steel blue with more a satin lustre. This is a really fine example of well crystallised Stibnite from Kremnica in Banská Bystrica, Slovakia.
