Amethyst — the purple quartz

Amethyst — the purple quartz

← Natural stones

Chemical formula – SiO₂
Hardness – 7
Colour – pale to deep violet, sometimes with a pink cast

Amethyst is the purple variety of quartz and one of the best known stones in that family. It belongs to the large-crystal branch, hardness 7, more than enough for daily wear. The one thing that genuinely harms it is sunlight.

The colour comes from iron impurities and natural irradiation; without them the stone would be plain clear quartz. The shade is often uneven — a dark core, lighter edges — and that zoning is a good sign the stone is natural.

The name is Greek: "amethystos" means "not drunk". People once believed the stone kept them sober, and not only from wine but sober in thought. It is still called the stone of sobriety.

Grades are simple: opaque pale stone is affordable, while transparent and deeply coloured pieces cost noticeably more. Amethyst is common enough that buying a real one is easy — the attention belongs on treated stones, not fakes.

Origins

The largest deposits are in Brazil, where the stone runs lighter and cleaner. Uruguay produces dark, saturated violet, and Uruguayan material commands the highest prices.

It is mined too in Bolivia, Canada, Mexico, Madagascar, Burma, Namibia, Russia, Sri Lanka, Zambia and the United States (Arizona). Zambian amethyst has gained real ground on the market over the past decade.

Properties

Tradition treats amethyst as the stone that clears away noise and brings a person back to themselves. For centuries it was held to help people let go of addictions and bad tendencies.

A stone kept in the bedroom is said to bring calm sleep and good dreams, which is why amethyst was long linked to sleep. Esoteric writers call it a strong but undemanding protector: anyone can use it, and it asks for no special preparation.

More broadly, amethyst is counted as the stone of the mind, creativity, calm and balance. In various cultures it has also stood for love and fidelity.

Traditional healing properties

Lithotherapists say amethyst supports metabolism and the immune system. It is said to ease headaches and relieve migraine.

Traditionally it was used to curb dependence. Amethyst is believed to improve circulation and to help with speech problems.

This describes traditional practice, not medical advice. A stone does not replace a doctor.

Chakras

Linked to the sixth, third-eye chakra – ajna.

Zodiac

It is the stone of February, which makes it Pisces first of all: a water sign that lives on intuition and often rides emotional waves, exactly what amethyst evens out.

It also suits Aquarius, whose subject is independent thought and a clear head, and Sagittarius, who often needs focus. Aries wears it well too — the stone takes the edge off a fire sign's hurry.

In Charcho jewellery

Amethyst necklaces are in the catalogue: necklaces. If you want a particular shape, write to us. The work is handmade and we take custom orders.

The stone is hard enough and holds its colour, so it works confidently in rings and earrings. In necklaces we favour the lighter tones, which sit more naturally against the skin.

Amethyst crystals

Real or fake

Amethyst is inexpensive, so fakes are rare. Treated stones are more common:

  • Heated. At around 500 °C the colour leaves and the stone becomes citrine. That is legal and widespread.
  • Irradiated. Produces a darker colour than nature would.
  • Dyed. Rare, but it happens, and a scratch shows it.

Glass imitations give themselves away with perfectly even colour and bubbles. In natural stone the colour is always distributed in zones — if you cannot see a transition of shade, you are most likely looking at glass.

Care

  • Sun. Long direct sun dulls the colour, so a windowsill is a bad home for it.
  • Ultrasonic and steam are usually safe, but skip them on a stone with a crack.
  • Warm water and a soft cloth are enough; it needs no heavy chemicals.
  • Store it dark and in its own pouch, and the colour stays unchanged for years.

  • Batumi humidity and leather

    Batumi humidity and leather

    ← Leather

    In Batumi, Sakartvelo, the air is damp for most of the year, and in summer the coastal moisture is joined by heat. Leather is a living material: it breathes and takes moisture from its surroundings. That is why a leather piece here needs different care than in a dry climate, not more frequent care but more attentive care.

    What humidity does to leather

    Leather absorbs moisture at fibre level. From outside it is barely visible, but the piece becomes heavier and softer. When there is plenty of moisture and the air does not move, the fibres stay wet for a long time. In that period leather is at its most vulnerable: it stretches easily, creases easily and picks up smells easily.

    On the other hand, humidity protects leather from drying out. The difficulty of the Batumi climate is not the damp itself, but that a piece often sits in a closed, unventilated place.

    Mould: how it starts

    Mould spreads by spores and looks for moisture and darkness. The first signs are a whitish or greenish bloom in the folds and near seams, and a smell you notice the moment the bag opens.

    What to do: take the piece into the air, in the shade, without a hairdryer, and let it dry. Then lift the bloom carefully with a soft dry cloth, outdoors, so the spores do not stay in the house. The surface can be wiped with slightly diluted vinegar, and afterwards a colourless conditioner goes on, because vinegar adds dryness.

    What not to do: no brush, no bleach-based products, no hot air. If mould has gone into the leather or the colour has turned patchy, show the piece to a craftsman.

    Deformation: leather stretches

    Wet leather takes a shape more easily than anything. A bag soaked in the rain and left hanging by its handle will stretch over time; a belt always fastened at the same hole creases exactly there. An overfilled wallet loses its corners.

    The answer is simple: a wet piece always dries flat or in its natural shape, with paper inside, never hanging.

    Daily habits

    • Never keep a bag in the bathroom, where humidity is highest.
    • When you get home, open the bag and leave it open for an hour.
    • Rotate your bags: leather needs rest.
    • In the cupboard, a moisture absorber and cotton bags, not polythene.
    • Direct airflow from an air conditioner dries leather, but ventilating the room is good.

    The long rains

    In Batumi, days of steady rain are ordinary. A bag comes home wet and there is not always a chance to leave it open all day. Two things are enough: paper inside, and a window open overnight. By morning the leather is dry.

    Once a month, look the bag over: seams, corners, where the handle attaches. An early sign is easy to correct; a late one is already a repair.

  • Leather history: from craft to luxury

    Leather history: from craft to luxury

    ← Leather

    Leather is older than the wheel and older than writing. For most of its life it was a cheap, rough material: it kept thorns out of a foot, held water on a journey, made a strap that did not snap. It reached the display case fairly recently, and the price tag is now explained by hand-stitching rather than by usefulness. Between those two points the road has a few clear bends.

    The oldest trace

    A hunter found in the Alps — known today as Ötzi — lived around 3300 BCE. His cap, coat and shoes were leather: bearskin soles, uppers laced with lime bast. Those pieces have held their shape for more than five thousand years. It is the strongest argument leather has, and we have never found a better one.

    Earlier still, in the Stone Age, hides were worked with smoke, fat and brains. In ancient Egypt leather became sandals, bags and waterskins, and alum was already used to dress skins. Excavations at Pompeii uncovered workshops where hides were processed — by the first century CE this was a city trade, not a household chore.

    A craft kept outside the walls

    In medieval Europe the tanner and the shoemaker sat in different guilds, with different prices and different standing. Tanning happened by the river, outside the town wall: it needed water, and the smell was not welcome indoors. Hides soaked in oak-bark liquor for months. That slow process produced the material we now call vegetable-tanned leather — and it is why old leather ages the way it does.

    Chrome and the sewing machine

    In 1858 Friedrich Knapp patented chrome tanning in Germany; in the 1880s Augustus Schultz worked out the two-bath process. Tanning fell from months to days. At the same time the sewing machine, spreading through the 1850s, took over part of the stitching. Together they turned a craft good into a product almost anyone could buy.

    How it became luxury

    In the second half of the nineteenth century, houses in Paris and Florence turned craft into brand. Hermès began in 1837 as a harness workshop, Louis Vuitton in 1854 with travel trunks, Gucci in Florence in 1921. Railways, then aircraft, made travel ordinary, and the trunk became a sign of who you were. Leather stopped being only a tool and started being a statement.

    Our place in that story

    Two families work in our workshop in Batumi, Sakartvelo — Chartolani and Chogovadze — and we have been cutting and stitching side by side for eighteen years. We invented nothing here. We keep the principle the medieval workshop kept: slow work, honest material, and a piece made to be handed on. There is nothing luxurious about that. It is simply the norm.

  • Leather and sustainability: myth and reality

    Leather and sustainability: myth and reality

    ← Leather

    Two opposite sentences get said about leather: "it's a by-product of the meat industry, so it's fine" and "it's an animal's skin, so it's not". Both hold half a truth, and those halves are exactly what stops people making a sensible decision.

    A by-product — but not a free one

    Leather is a companion product of meat and dairy. Cattle are not raised for their hides. If the raw material is not processed, it becomes waste: buried, burned or stockpiled. Seen that way, tanning is genuinely a smaller loss than throwing hides away.

    But "by-product" does not mean "no cost". Tanning needs water, chemicals and energy; transport needs fuel. The price paid for a raw hide is a small share of what the animal is worth, so leather production does not fund livestock farming. That argument is usually overstated — it only sounds clean if you stop looking at the whole chain.

    Chromium, water and tannins

    Most of the world's leather is tanned with chromium salts. Trivalent chromium itself is not the danger; the trouble starts where the process is badly run and hexavalent chromium forms, or where wastewater is not treated at all. Tanneries working under regulation clean their water. Informal workshops often do not.

    Vegetable tanning uses tannins from bark and needs no chromium. In exchange, the process runs for weeks, uses a lot of water, and produces effluent heavy with organic load. So "vegetable equals green" is too simple an equation: the shape of the problem changes, its existence does not.

    Are synthetics actually cleaner?

    Polyurethane and PVC come from petrochemicals. They do not break down the way leather does, they shed microparticles under hard wear, and they often fail within two or three years. Plant-based "vegan leather" usually binds its fibre with a polyurethane binder — so the plastic is still there. The impact is different, not absent.

    What genuinely works

    • Longevity. One leather bag carried for fifteen years beats three cheap replacements.
    • Repair. A handle, a clasp and a seam can all be fixed, and that adds years to a piece.
    • Transparency. Some tanneries submit to independent audit (LWG), so asking "where is this leather from?" is always fair.
    • Care. In Batumi's humidity leather drifts toward mould; a dry, ventilated place and occasional conditioning are enough.

    What we say

    We do not call ourselves an eco-brand and we do not sew on a green label. We say only what we can stand behind: we buy hides as a by-product, we ask suppliers questions, we do not throw offcuts away — small pieces become small goods — and we build a bag so that it can be repaired. That is not a sustainability certificate. It is simply our rule.
