Very attractive daylight fluorescent gemmy green Fluorite from the well regarded Heights Mine, Weardale (a specimen collected pre 1970 in the George Farr Collection, the Heights Mine has been inaccessible for many years). Crystals of Fluorite measuring to 1.5cm display the classic interpenatrant twinning habit to advantage, and are abundantly clustered over the altered Fe-oxide brown Limestone matrix, so typical of the mine. A super specimen from the mine.
