How Much Is Fluorite Worth?
Also known as Fluorspar
Fluorite is a soft, glassy mineral famous for its range of colors — purple, green, blue, yellow, and multicolor 'rainbow' banding — and for its strong fluorescence under UV light. It's affordable to mid-range: tumbled stones and small octahedrons sell for $2–$20, carved spheres, towers, and palm stones for $15–$80, and fine crystal specimens (sharp cubes or 'rainbow' bands from classic localities) for $40–$500+. Value comes from color intensity and combination, crystal form (well-defined cubes and octahedrons), transparency, and locality — English (Rogerley), Chinese, and Illinois fluorite are all collected. Because fluorite is soft (Mohs 4) and cleaves easily, undamaged, sharply formed crystals carry a premium, and gem-clear faceted fluorite is a niche collector item rather than a durable ring stone.

What drives fluorite value
- Color. Vivid, saturated color and attractive multicolor banding are top drivers.
- Crystal form. Sharp, undamaged cubes and octahedrons command premiums.
- Transparency. Gem-clear, glassy material beats cloudy or fractured stone.
- Locality. Classic sources (Rogerley UK, Illinois, China) add collector value.
Is your fluorite real?
Fluorite is rarely faked, but glass imitations and dyed pale material exist. Genuine fluorite is soft (Mohs 4 — a steel knife scratches it), shows perfect octahedral cleavage, and often fluoresces under UV. Anything that resists a knife scratch is harder than fluorite and likely glass or quartz.
FAQ
- Is fluorite valuable?
- Modestly for common tumbled pieces ($2–$20), but sharp crystal specimens and fine rainbow or locality material reach $40–$500+.
- Why is fluorite so soft?
- It's Mohs 4 with easy cleavage, so it scratches and chips readily — handle and store it carefully, away from harder stones.
