| Description: | A specimen of fluorspar from the Corrie Beg (Glengairn) Veins, Ballater, Aberdeenshire. The veins were worked in the early 1800s for galena, a lead ore. British Geological Survey Petrology Collection sample number MC 7409. The galena was rich in silver. As well as galena and fluorspar the vein yields yellow zinc-blende and calcite. Fluorspar is a mineral belonging to the cubic crystal system. It has a hardness of four on Moh's scale of hardness (semi-hard), and is a fragile mineral with perfect cleavage and vitreous lustre. When fluorspar is exposed to ultraviolet light it fluoresces strongly, usually blue or violet. |
