Fluorite





 Location Found: Franklin and Ogdensburg
     
 
 Year Discovered: 1529
     
 Formula: CaF2
 Essential Elements: Calcium, Fluorine
 All Elements in Formula: Calcium, Fluorine
     
 IMA Status: Valid - first described prior to 1959 (pre-IMA) - "Grandfathered"
     
Fluorescent Mineral Properties

 Shortwave UV light: White, pale yellow, greenish-yellow, blue-green, green, and blue-violet, variety chlorophane moderately bright blue-green
 Mid wave UV light: White, pale yellow, greenish-yellow, blue-green, green, and blue-violet, variety chlorophane moderately bright blue-green
 Longwave UV light: White, pale yellow, greenish-yellow, blue-green, green, and blue-violet, variety chlorophane moderately bright blue-green
 Additional Information: Chlorophane rapidly loses its fluorescence and phosphorescence (moderately bright blue-green) on exposure to light. Occasionally fluorescence color changes with UV wavelength.
