ROGERLEY MINE FLUORITE
WEARDALE FLUORITE

(Rogerley Mine, Weardale, County Durham, England, UK)

In the 1970’s a couple from the USA went to visit an abandoned limestone quarry in England and found these unique and rare fluorite specimens. They purchased the mine and it has run continuously in the summer months for 47 years. This mine is the only active mine in the UK operated on a commercial basis solely for specimen recovery. In 2017 the operation was sold to UK Mining Ventures, operated by another rockhounding couple. They mine for dark green fluorite, sometimes with galena included in the matrix. This fluorite is called Weardale Fluorite, named after the area, but many people call it Rogerley Mine Fluorite, after the mine itself. These specimens have well formed cubic fluorite on limestone or ironstone matrices. The cubes are dark green, and fluoresce a brilliant blue under UV light (some rare specimens fluoresce blue in daylight!). The word fluorescence comes from this mineral; fluorite. Galena (lead) octahedrals are also sometimes found growing with the fluorite. Quartz crystal druzy is sometimes found coating the fluorite as a secondary growth. These are highly sought after specimens for collection.
