Rogerley Mine Fluorite
The Dark Green Treasure of Weardale
Also known as: Weardale Fluorite
About the stone

Rogerley Mine fluorite is calcium fluoride prized for emerald-green, often interpenetrating cubic crystals and striking daylight fluorescence, which can make the crystals appear violet-blue outdoors. Collectors Lindsay Greenbank and Michael “Mick” Sutcliffe discovered its mineralized veins in 1972 within an abandoned nineteenth-century limestone quarry near Frosterley, Weardale, County Durham, England; Rogerley subsequently became a pioneering British mine operated specifically to recover mineral specimens rather than industrial ore. Its name identifies this particular locality, so fluorite from neighboring mines should not automatically be labeled Rogerley. Descriptive market names include “Rogerley fluorite,” “Rogerley green fluorite,” and “daylight-fluorescent fluorite,” while “fluorspar” is an older name for fluorite generally.

Care and handling
Rogerley Mine Fluorite is soft, with a hardness of 4, and has perfect cleavage, so these cubes can split or chip if dropped; keep them in a padded case. Heat, strong sunlight, and sudden temperature changes can fade or crack them. Specimens may include galena (lead) in the matrix, so wash your hands after handling, do not grind or sand them, and keep them from children and pets. Clean only with a soft dry brush or barely damp cloth. Avoid soaking, steam, ultrasonic cleaners, and acids. Do not make gem water or an elixir with them.
Individual experiences with Rogerley Mine Fluorite vary, and its effects are personal and subjective. Approach it with a mindful and open heart, and enjoy it as a rare and beautiful collector's piece.
