3.3" Fluorescent Green Fluorite Cluster - Diana Maria Mine, England

The Diana Maria mine is a part of the Rogerley quarry in County Durham, England. It began as a surface mining operation in 2017 and graduated into tunneling operations in 2018. Several pockets of breathtaking fluorite specimens have been discovered within the mine, including Graeber Jones, Snowstorm, Green Hill, Emerald Peaks, Heavy Metal, Purple Haze, and many more. Many of these pockets helped to establish new standards for the quality of Rogerley fluorite.

The Rogerley Mine is located in the historic Weardale mining District of Northern England. First discovered in the early 1970s, the Rogerley Mine is the only mine in all of Britain to be worked on a commercial scale in the name of collecting crystallized mineral specimens. Since the summer of 1999, UK Mining Ventures has operated the Rogerley Mine on a seasonal basis, producing many fine, well crystallized specimens of green fluorite. Rogerley material is considered some of the finest fluorite in the world, and much of it has incredible fluorescent properties under both daylight and ultraviolet light.
