FLUORITE

  • Occurs in purple, blue, green, yellow, reddish orange, pink, white, black and brown.
  • Pure fluorite is colorless (by this I mean clear).
  • Most common found in cubes and/or octahedron or coarsely sized crystals.
  • Chemical Formula : CaF2
  • Fluorite is also known as Fluorspar
  • Cleavage is a perfect in 4 directions forming octahedrons.
  • Fluorite is 4 on the Mohs Scale of hardness.
  • Luster : vitreous
  • Streak: White
  • Density: 3.18
  • Name in Latin: fluere = to flow
  • Group: Halides
  • Fluorite is a fairly common mineral, and is associated with quatz, calcite, dolomite, galena, pyrite, chalcopyrite, sphalerite, barite, and various other hydrothermal- vein minerals.
