Green Fluorite Pyramid Size 1.75"x1.5"x1.5":$49 Citrine's color comes from traceA pyramid that holds the full fluorite color spectrum in a single carved face. Fluorite is calcium fluorideCaFa halide mineral with a Mohs hardness of 4 and perfect octahedral cleavage in four directions, which is why a fractured edge catches light in a characteristic staircase pattern. Green fluorite owes its color to trace impurities within the crystal structure; the same species produces purple, blue, yellow, and colorless specimens from the same
