Fluorite
Fluorite — calcium fluoride, the mineral that gave fluorescence its name — is the crystal world's rainbow stone: a single piece can band purple, green, blue and gold in translucent layers. Softer than quartz (4 Mohs) and sometimes called "soft crystal," it glows under ultraviolet light and has been carved into ornamental objects for centuries. Its color-zoned patterns make every piece unrepeatable.
What Is Fluorite?
Fluorite Colors
- Purple & green — the classic combination; traditionally linked to calm focus.
- Blue ("unicorn") — dreamy blue-violet tones, prized for their ethereal look.
- Rainbow — multi-zone pieces showing the full spectrum in one stone.
What Is Fluorite Good For?
Fluorite is the focus stone: traditionally associated with mental clarity, concentration and organized thinking — a favourite for students, researchers and anyone doing deep work. Practitioners use it to settle scattered thoughts and bring order to busy minds, describing its energy as cool, clear and quietly structuring. It's also valued as an aura cleanser, traditionally said to sweep away stagnant energy and leave the atmosphere feeling fresh.
How to Use Fluorite
- Study & work — Keep a bracelet or tumbled stone on the desk as a traditional anchor for concentration.
- Wear it daily — Our rainbow and unicorn-blue bracelets bring its calm clarity everywhere.
- Display carvings — Butterflies, foxes and bears in banded fluorite make joyful desk companions.
- Before big tasks — Hold it briefly and set a clear intention for focused, orderly work.
Care & Cleansing
- Handle gently — fluorite (4 Mohs) is soft with perfect cleavage; it scratches and chips easily. Never wear it against harder stones.
- Avoid heat, sudden temperature changes and prolonged strong light.
- Cleansing: rest it overnight on a Clear Quartz cluster — the simplest daily reset — or leave it in moonlight around the full moon. Skip water-based methods for this stone. Read our full cleansing guide.
- Avoid salt water — some shops recommend it as a cleansing method, but salt can permanently dull or damage the surface.
