Fluorite occurs throughout the world, and is a very common mineral. Only classic and exceptional localities will be listed here. England has produced some of the finest specimens, especially in Weadale, North Pennines, Co. Durham. Green cubic crystals have come from the famous Rogerly Mine in Weardale, and these uniquely exhibit daylight fluorescence, changing to a saturated blue color in sunlight. Other English occurrences in the North Pennines region are Nenthead (Alston Moor District); the Hilton Mine, Scordale; and East Allendale (Allenheads Mine and St. Peters Mine).
Bright blue Fluorite crystals are known from several areas in France. Three particular important localities are Le Burg (Le Burc) and Mont-Roc, both in Tarn, and Le Beix, in Puy-de-Dome. Pink octahedrons, highly valued by collectors, were found in the Alps near the Argentiere Glacier, Mont Blanc, Chamonix, France; and at Göscheneralp, Uri, Switzerland. Fine crystals are also found in Spain in Caravia, Asturias, especially in the Berbes, La Collada, and Villabona areas. In Germany, fine Fluorite has come from the Erzgebirge in Saxony at Frohnau and the Freiberg District.
Excellent Fluorite specimens are well known from Dal'negorsk, Primorskiy Kray, Russia, and these are very highly regarded by collectors. China has become an excellent producer of Fluorite, with notable occurrences at the Yaogangxian mine, Hunan Province; Shangrao (De'An), Jiangxi Province; the Huanggang Mine, Inner Mongolia; and the Shangbao Mine, Hunan Province. Rounded botryoidal balls, a rare form for Fluorite, comes from Mahodari, Nasik District, Maharashtra, India.
In South Africa, excellent deep-green Fluorites were recently discovered in Riemvasmaak, Northern Cape Province. This occurrence has become one of the most popular Fluorite localities in recent times. The Erongo Mountains of Namibia have produced a highly desirable and unique habit of green Fluorite in cuboctahedral form with an "alien eye" appearance.
In South America, excellent Peruvian localities include the Pasto Bueno District, Pallasca Province, Ancash; and the Huanzala Mine, Huallanca District, Huanuco. Mexico has some fine notable Fluorite locations, specifically Naica, Chihuahua; Melchor Muzquiz, Coahuila; and Mapimi and Navidad, Durango. Canada has produced some some fine crystals, in the Rock Candy Mine, Grand Forks, British Columbia.
The U.S. also contains numerous fine Fluorite occurrences. Hardin Co., Illinois, has produced more collectible specimens than anywhere in the U.S., and the locations of Rosiclare, Cave In Rock, and the Harris Creek District (Denton and Annabel Lee Mines) are very famous. Other excellent Fluorite deposits are Marion, Crittenden Co., Kentucky; Clay Center, Ottawa Co., Ohio; the Elmwood Mine, Carthage, Smith Co., Tennessee; Grant Co., New Mexico; and Walworth, Wayne Co., New York. Excellent green octahedron
s are found in Westmoreland, New Hampshire. Another very important occurrence is the Blanchard Mine, Bingham, Socorro Co., New Mexico.
