A superb daylight fluorescent specimen of Fluorite from the mineralogical heart of Weardale, Co Durham. The Fluorite displays a plethora of interpenetrating green cubic crystals. The crystals are mostly gemmy having an excellent high luster, and strong purple daylight fluorescence. The largest twinned crystal group is actually composed of three crystals. The two large crystals to 2.3cm on edge are joined with a small 1cm crystal on edge. This exceptional specimen was discovered during the summer of 2008, in the Blue Bell Pocket, which was a continuation of the Jewel Box pocket - one of the most successful pockets found. The larger Fluorite cubes are free from the white internal frosting (commonly seen at Rogerley) which gives them a really gemmy deeply coloured appearance. Featured in our Hall of Fame!
