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.
