A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Fluorite is calcium fluoride (CaF₂), renowned for its wide color range—including purple, green, blue, yellow, colorless and multicolored banded forms—and for strong fluorescence under UV light in many specimens. It crystallizes in the cubic system and has perfect octahedral cleavage in four directions. With Mohs hardness 4, it is relatively soft and better suited for collector pieces and occasional-wear jewelry than for heavy daily use.
