Greenlaws Mine, Daddry Shield, Weardale, Co. Durham, England, United Kingdom

The Greenlaws mine is located in Weardale, in the northern Pennines of England, south of the small town of Daddry Shield. Around we find famous mines such as Rogerly, Boltsburn or Heights... This Greenlaws mine was worked for the galena between 1840 and 1901, being one of the most important lead mines in the area. In 2009 a group of collectors started the "Greenlaws mining project". After almost 5 years digging out the vertical shaft over 80 meters (270 ft) appeared the first specimens of fluorite, ending 2013.
This specimens we propose has been extracted from vugs found in a new connecting tunnel at 270 ft, between main shaft to a second contiguous adit. Good brilliance, transparence, with geometric color zoning that varies between purple to blue according to the incident light. With defined faces and edges and these characteristic whitish internal structures. Extremely fluorescent.
