Key Differences

  • Halite (NaCl) is sodium chloride; fluorite (CaF2) is calcium fluoride — different halide minerals.
  • Halite has cubic cleavage and dissolves readily in water; fluorite has octahedral cleavage and is insoluble.
  • Halite (hardness 2–2.5) is significantly softer than fluorite (hardness 4).
  • Fluorite is famous for its brilliant colors and fluorescence; halite is typically colorless to white.
  • Both crystallise in the cubic system as isometric minerals.
