Calcite, Fluorite, Sphalerite, Galena
Weardale, North Pennines, Co. Durham, England, UK
Large Cabinet, 18.0 x 11.2 x 7.4 cm
A very LARGE and RICH old Weardale piece, with dozens of cubes of gemmy purple fluorite interspersed with platy calcites. Under fluorescent light, the calcites glow pink and of course the fluorites are an intense bright purple (this is after all the locality which lent its fluorites to discovery of the phenomenon of fluorescence!). The fluorite crystals measure to 0.7 cm on edge. 18 x 11.2 x 7.4 cm
