FLUORITE
Rogerley Mine
Frosterley, Weardale
County Durham, United Kingdom

Cabinet
3.2 x 1.6 x 3.5 Inches
8.5 x 4.5 x 9.5 Centimeters

Multiple penetrating twin crystals and perfect cubes collapse into a vertical vug giving this piece fantastic depth. On several of the prominent crystals great etching patterns are present which adds even more character to this strong specimen. As you can see in the pictures, the UV reaction is bright and to top it off the daylight reaction is equally stunning.

Rogerley fluorite is one of our favorite minerals for its natural ability to color shift in sunlight(blue), artificial(green) and UV(purple) light. The source responsible for the amazing colors is a bit of a mystery but it is believed to be a result of structural defects and not influenced by outside sources.

The word Fluorite derived from the Latin "fluo" - to flow, because the mineral is used as a flux in iron smelting.

Fluorites from certain localities exhibit a very strong fluorescence, due to impurities in the crystal. In 1852 the phenomenon of fluorescence was named after fluorite. It also gave the name to its constitutive element fluorine.

Fluorite has a wide range of colors, which depends on impurities, exposure to radiation, and the size of the color centers. Color distribution is often zonal or spotty.

Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.
