Rogerley Mine, Rogerley Quarry, Weardale, County Durham, England

This specimen features a good coverage of minty green, lightly frosted fluorite cubes on matrix. These fluorites reach 1 cm on an edge. Minor, mostly dark and corroded galena (typical for the locality) also present. As is typical for Rogerley Mine, the fluorites display a brilliant and intense bluish fluorescence under shortwave UV (second photo). Similar color under longwave UV, but less intense. This material is so sensitive to longwave UV that a bluish tint can be seen when the specimen is viewed in sunlight - often even on an overcast day - due to the UV content of natural sunlight. Some scattered edgewear is noted but the damage is not significant. Displays nicely without needing a stand.
