Fluorite
Purple, blue, green, gold — color layered into a story, the way only raw stone tells it.
Fluorite (CaF₂, calcium fluoride) is one of the most colorful natural stones of all — purple, blue, green, gold and pink. Hold it to the light and bands of color rise through it; under ultraviolet light it glows blue-violet, the very property that gave the word fluorescence its name. At Mohs 4 it is a soft, wonderfully expressive mineral, and as raw stone no two pieces ever share the same face.

◆ About Fluorite
Fluorite (CaF₂, calcium fluoride) is among the most colorful natural stones and minerals in the world — purple, blue, green, gold and pink. Beyond clear single colors, it also appears as rainbow fluorite, with several colors layered in bands, so that no two stones ever wear quite the same expression.
Long nicknamed the “genius stone” and the “stone of the mind”, fluorite has traditionally been associated with focus, inspiration, intellect, cleansing and harmony. It has been carried as a charm for study and work, and given as natural-stone jewelry, for generations.
Set as raw stone, its bands of color and its inclusions become the character of the piece itself. Because the surface is left unpolished, the depth of color and the way the bands run differ from one stone to the next — the great appeal of raw fluorite.
The quiet of purple, the clarity of blue, the freshness of green, the warmth of gold, and the story told by layered color — fluorite is a natural stone that seems to speak in color, in a way only raw stone can.
◆ The Many Faces of Fluorite
Every piece differs in hue and inclusion — the unrepeatable character of raw stone.

◆ One of the most colorful minerals on Earth
Purple, blue, green, gold, rainbow — fluorite’s palette seems endless.
Fluorite’s range of color is exceptional even among natural stones and minerals. The differences come from trace elements and natural irradiation, and each locality tends to show its own signature hues: Chinese fluorite is often purple and green, Mexican material runs to clear blues and rainbow banding, and South African stones to deep green. The same mineral, a different landscape with every source — that is fluorite.
◆ Fluorescence — the glow that gave it its name
The property that makes fluorite special, written right into its name.
Fluorite glows blue-violet under ultraviolet light. The name comes from the Latin *fluere*, “to flow”, and from the mineral itself the word fluorescence was born. The strength of the glow varies a great deal from stone to stone and is most striking in the purple material — a second face the stone keeps hidden under ordinary light.
◆ Choosing raw fluorite jewelry
Choose by color and size — and handle it gently to enjoy it for years.
At Mohs 4, fluorite is one of the softer minerals, so jewelry that keeps the raw stone asks to be handled gently, away from knocks and abrasion. Purple reads classical and formal, blue is cool and easy for everyday, green is casual, and rainbow material makes an accent for special days — part of the pleasure of fluorite is how each color suits a different moment.
TROZO sets fluorite without polishing away its character, letting the natural color and inclusions lead the design. We offer pieces for those who would like to choose the color from stock, as well as pieces where the meeting with the stone is left to chance. Choose by how it sits with the jewelry you already own, or simply by the mood of the day.
