University of Minnesota's Mineral Pages: Fluorite
However, quartz is much harder than fluorite. It will scratch glass and, unlike fluorite, it cannot be easily scratched by metal. Quartz also lacks any cleavage and breaks in a conchoidal manner, while fluorite has four perfect cleavage directions. In addition, fluorite will often fluoresce under ultraviolet light. Halite:
