Fluorite is commonly gray, white, or colorless, but it may also be green, blue, purple, pink, or yellow. The streak is colorless and the luster glassy. Fluorite can be scratched by a knife or a piece of window glass, is fairly lightweight (specific gravity ranges from 3 to ), and is transparent to translucent.
