Green fluorite is the stone people pick up and turn over in the light. It is one of the few materials in our collection that changes noticeably as you move it: a bead that reads flat mint from one angle can show a seam of deeper green, or a drift of colourless glass, from another.
It is also one of the softer stones we work with, which shapes how it is cut, strung and worn. Here is what that means in practice.
What green fluorite is
Fluorite is calcium fluoride, a mineral that forms in cubic and octahedral crystals. It occurs in a wide range of colours — purple, blue, yellow, colourless — and green is among the most common. The colour comes from trace elements and structural quirks in the crystal, not from any treatment or dye in the material we use.
Its most recognisable feature is transparency. Good green fluorite is glassy rather than stony, and light travels some way into a bead before it stops. Held against a window, a well-cut round can look almost like a drop of water with green suspended in it.
Colour banding
Fluorite grows in layers, and those layers often differ in colour. When a bead is cut from a crystal, the cut runs across those layers and the banding shows up on the surface of the sphere as stripes, wedges, or soft gradients.
This is why no two beads on a fluorite bracelet look the same. On a single strand you might see:
- Beads that are almost uniformly pale green, with only a faint clouding
- Beads with a clear band of saturated green running through the middle
- Beads that shade from green into colourless, sometimes with a hint of blue or purple at one edge
- Small internal fractures that catch light and read as a flash or a fine seam
Those internal features are normal in fluorite, not faults. We sort beads for tone and place them along a strand so the colour moves in a way that looks intentional, rather than trying to match every bead to a single shade. That sorting is done by eye, by hand, at the bench in Xingyi — you can see how it comes out across the current pieces in the Mistfell shop.
Why it is handled carefully
Fluorite sits at 4 on the Mohs scale of hardness. For comparison, quartz — including amethyst — sits at 7, and window glass is around 5.5. Fluorite is soft enough to be scratched by a sand grain, a steel key, or a harder stone in the same drawer.
It also has perfect cleavage in four directions, meaning the crystal has natural planes along which it parts cleanly. A sharp knock in the wrong direction can chip a bead along one of those planes rather than simply scuffing it.
That affects the whole process. Drilling is slow. Beads are checked individually before stringing, because a hairline chip near a drill hole is easy to miss and difficult to live with later. Finished bracelets are packed so the beads are not pressed against each other in transit.
Wearing and keeping it
None of this makes fluorite delicate to the point of being impractical. It makes it a stone to be slightly deliberate about.
- Store it on its own, or in a soft pouch, rather than loose with harder stones and metal
- Take it off for washing up, gardening, gym work, and anything with grit or knocks involved
- Clean it with a soft dry cloth, or a barely damp one; skip ultrasonic cleaners and household chemicals
- Keep it out of long, direct sun, which can dull the colour of some fluorite over time
Worn on the days it suits and put away on the days it does not, a fluorite bracelet holds its surface well. Our pieces are made in small numbers by named makers, and the strand in the photograph is the strand that arrives — banding, seams and all. They are also available to buyers worldwide through our Etsy shop.
Questions & answers
How hard is green fluorite, and does it scratch easily?
Fluorite is 4 on the Mohs scale, softer than quartz (7) and window glass (about 5.5). It scratches fairly easily, so it is best stored separately from harder stones and metal jewellery.
Why do the beads on a green fluorite bracelet look different from each other?
Fluorite grows in coloured layers, so each bead is cut across a different part of the crystal. Variation in tone, banding and clarity between beads is normal and expected.
How should I clean a green fluorite bracelet?
Wipe it with a soft dry or barely damp cloth. Avoid ultrasonic cleaners, hot water, and household cleaning products, and remove the bracelet before washing up or using hand sanitiser.
