                  Rare Rough Opalized Fluorite!
                  This material is one of the most scarce, 
          beautiful and unusual stones in the world, this stone only comes from 
          one very small area of beryllium mines in the Utah west desert where 
          they mine (the 4th lightest element) beryllium for use in missile nose 
          cones and many other high-tech metallurgical uses. It is not open to 
          the public for collecting and very little of this material sees 
          anything other than the ore crusher to extract the about 1% to 2% 
          beryllium contained in the opal tuff. Try to find this exquisite 
          gemstone and you'll see that it's not only  very rare, it is 
          very scarce. It is a soft to hard opalized stone that forms in 
          very small to 100+ pound "nodules", composed of predominantly 
          opalized fluorite (blues, purples and whites), often with many 
          other minerals such as quartz, dolomite, rhodonite, manganese, 
          beryllium and other surprises. It often has a "crackled" appearance 
          and is sometimes called "Tiffany Stone", "Bertrandite" "Purple Opal" 
          or "Ice Cream Opalite". I call it Opal-Fluorite.
