Green Fluorite: A Closer Look

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.

Amethyst, by Colour: Pale Lilac to Deep Violet

Amethyst is the purple variety of quartz, and purple turns out to be a wide word. Lay a handful of amethyst beads on a linen cloth and you will see the range at once: some the colour of a pale wash, some so saturated they read almost black until you lift them to a window.

None of this is a grading system. It is simply what the stone does, and what to look for when you are choosing a bracelet you will actually wear.

The range, described plainly

  • Pale lilac — a barely-there purple, closer to grey-mauve in low light. Reads soft against every skin tone and almost disappears under a shirt cuff.
  • Lavender — clear and cool, the colour most people picture first. Even, unhurried, easy to wear beside silver or a pale stone.
  • Mid violet — the middle of the range, warmer, with a faint red note in strong light.
  • Deep violet — dense colour that holds its own. In shade it can look near-black; in daylight the purple opens up.
  • Banded and zoned — beads where colour sits in visible stripes or patches rather than spreading evenly. We tend to keep these. They are the ones that look most like the rock they came from.

What affects how purple it looks

Three plain things account for most of the variation you will see across a strand.

The stone itself. Amethyst’s purple comes from trace iron within the quartz structure. How much is present, and how it is distributed, varies from one piece of rough to the next — which is why beads cut from different material never match perfectly, even when they are sold as one colour.

Colour zoning. Purple in amethyst is rarely spread evenly through the rough. It often concentrates in bands or towards the tip of a crystal. A bead cut from the deep part comes out saturated; a bead cut from the pale part comes out soft. Same stone, same seam, different slice.

Size and cut. Light has further to travel through a large bead than a small one, so the same material looks deeper at 10mm than at 6mm. Polish matters too: a high shine bounces light off the surface and lightens the read, while a matte or frosted finish looks quieter and slightly greyer.

Light changes everything

Amethyst is one of those stones that behaves differently by daylight and by lamplight. Under warm indoor bulbs the red note comes forward and mid-violet beads can look almost plum. Under a window on a grey morning the same beads turn cooler and clearer. Neither is the true colour; both are.

This is worth knowing before you buy anything online. A photograph is one lighting condition, held still. We shoot our pieces in daylight, without colour correction, and the piece in the photograph is the piece that arrives — but the bracelet on your own wrist, in your own kitchen, will show you a slightly different face of the same stone.

Choosing across the range

Pale amethyst sits well with turquoise, moonstone and green fluorite — it lets the other stone lead. Deep violet is better on its own, or with a single dark accent, because it will take over any strand it joins. Mid violet is the most forgiving of the three, and the easiest to wear daily.

If you are unsure, the practical answer is to look at what is actually available rather than at a colour chart. Each piece in the Mistfell bracelet collection is strung by hand in Xingyi, Guizhou, by makers including Wu Yunhua and Fanfan, and photographed individually — so you are choosing a specific strand of specific beads, not a colour name.

Buyers outside China can find the same pieces in our Etsy shop, where the listings carry the same photographs.

Questions & answers

Is darker amethyst better quality than pale amethyst?

No. Depth of colour is a matter of appearance and preference, not quality. Deeply saturated amethyst is less common in the rough, but a pale bead can be just as clean, well cut and well polished.

Why don't the beads on my amethyst bracelet all match exactly?

Purple in amethyst is rarely distributed evenly through the rough stone, so beads cut from different parts of the same material vary in depth and can show banding. On a handmade strand this variation is visible rather than sorted out.

Does amethyst fade?

Amethyst's colour can lighten with prolonged, direct sunlight or high heat. Storing a bracelet out of a sunny window and away from heat sources is enough for ordinary wear.

How to Choose a Crystal Bracelet That Actually Fits

Most bracelets that get set aside were never uncomfortable in the shop. They were the wrong length by five or six millimetres, or the beads were larger than the wrist could carry. Both are easy to avoid, and neither requires anything more than a strip of paper.

Measure the wrist first

Take a strip of paper about a centimetre wide, or a soft tape measure if you have one. Wrap it around your wrist just below the wrist bone, where a bracelet naturally settles. Draw a line where the paper meets itself, lay it flat against a ruler and read the number in millimetres.

A few small things make the reading more reliable:

  • Keep the paper snug against the skin but not pulled tight.
  • Measure your dominant wrist, which is usually the slightly larger of the two.
  • Measure at the end of the day rather than first thing in the morning. Wrists change size a little over twenty-four hours.
  • Write the number down. It will not change much, and you will want it again.

That number is your wrist circumference, not your bracelet size. The bracelet needs to be longer.

Adding the comfort allowance

A beaded bracelet is a closed circle of solid stone. It has no clasp to open and no give in the beads themselves, so it must be able to slide over the widest part of the hand and then sit loosely enough to move as you move.

As a general guide, add between 10mm and 20mm to your wrist measurement:

  • Close fit, around 10mm added. The bracelet sits high on the wrist and moves very little. Best with smaller beads.
  • Standard fit, around 15mm added. The bracelet turns freely and slides an inch or so down the hand. This suits most people and most bead sizes.
  • Relaxed fit, around 20mm added. The bracelet hangs lower and is easier to pull on. Worth choosing if you have a broad hand relative to your wrist, or if you like to stack several pieces.

If you have wide knuckles or a firm thumb joint, measure across the widest point of your closed hand as well. The bracelet has to clear that measurement to go on at all.

Bead size changes the fit

Bead diameter is the part people tend to overlook. Larger beads take up more of the inner circumference of the circle, which means a bracelet made from 10mm beads sits differently on the wrist than one made from 6mm beads of the same total length.

  • 6mm to 8mm. Light, low profile, comfortable under a cuff or a shirt sleeve. Sits well on slimmer wrists and stacks easily.
  • 8mm to 10mm. The most common range. Enough weight to feel present without being heavy.
  • 10mm and above. Noticeably heavier and wider. Handsome on a broader wrist; on a narrow one it can look like it belongs to someone else.

If you are unsure, 8mm is the safest first choice. It is forgiving across a wide range of wrists and works with almost anything else you already wear.

Weight, stone and daily wear

Different stones have different densities, so two bracelets of identical bead size can feel quite different on. Agate and turquoise tend to feel substantial. Fluorite and moonstone read a little lighter. None of this affects sizing, but it does affect whether you reach for the piece on a Tuesday morning.

Because our bracelets are strung by hand in small numbers, lengths vary slightly between pieces, and each listing gives its own measurement. Send your wrist measurement with an order and we will match you to a piece that suits it, or string one to length where the stone allows.

You can see the current bead sizes and lengths across the handmade crystal and stone bracelets in the shop, each photographed as the piece you would receive. For orders outside our usual shipping regions, the same collection is listed on our Etsy shop.
