The very best, spectacular and World Famous stunning Green, cubic Fluorite Crystals, and crystal cluster specimens like this one, are discovered in the Diana Maria Mine, Frosterley, Weardale, County Durham, United Kingdom. They are the most gemmy quality Fluorite crystals in the world and pretty valuable! This magnificant Green Fluorite crystal cluster we proudly offer to you. This marvelous cluster shows also intense blue fluorescence! We would like to show this to you in several photos. In normal, daylight first and under extra ultraviolet light (UV light) second. To see this blue colour, you need a 365 & 395 UV Light source. (You already can buy a high-quality flashlight with this special UV light for approximately € 15,- on the internet). Which part of the crystals wll turn into blue, depends of the shing angle of your flashlight. These exclusive Fluorite crystals are found in just one of the approximately 20 pockets in the Diana Maria Mine, the Emerald Peaks Pocket. So called because these Fluorite crystals look like Emerald. The outer faces of these fluorite crystals tend to be a gemmy sea-green, with many of the centres slightly cloudy, in paler, mossy shades of green. This small zone quickly gave way to beautiful deep leaf-green to emerald-green twinned fluorites, often with distinct colour zoning. Absolutely a rare, valuable and ‘must have’ item for your collection!
