# Amethyst: virtues, meaning and how to wear it

Published on **24/07/2026** · By **Sébastien Joumel**

In brief

**Amethyst is a purple quartz, hard (7 on the Mohs scale) and very common, which tradition links to calm and serenity.** Beautiful and affordable, it has one flaw to know: it fades in direct light. Here's what it really is, what tradition says, and how to choose and care for it.

## What amethyst is

Amethyst is the **purple variety of quartz** (silicon dioxide); its colour comes from traces of iron and natural irradiation. Its hardness of **7 on the Mohs scale** suits all jewellery. Shades run from pale mauve to deep violet; the darker ones are most sought after. Note: prolonged sun exposure **fades** amethyst.

## Meaning & virtues in tradition

In crystal tradition, amethyst is the calming stone par excellence: it is said to soothe the mind and support sleep and meditation. **These virtues are traditions and beliefs: they are not scientifically demonstrated and replace no medical advice** (see sources).

## How to wear and choose it

Hard and affordable, amethyst suits bracelets and rings alike. To preserve its colour, avoid wearing it in full sun all day and store it away from light. When buying, an overly vivid, uniform colour on a cheap stone may indicate a heated or synthetic stone — acceptable if disclosed. See our [natural stone jewellery guide](https://meilleures-bijouteries.fr/en/guides/natural-stone-jewellery-guide/).

## Care

Lukewarm water and a soft cloth. Avoid heat and prolonged direct light, which dull the colour. No ultrasonic cleaning on a cracked stone.

## Frequently asked questions

What are the virtues of amethyst?

Tradition attributes calm, sleep support and meditation to it. These virtues are beliefs, with no scientifically demonstrated effect, and replace no medical advice.

Why has my amethyst faded?

Amethyst fades under direct, prolonged sunlight, as its colour is UV-sensitive. Store it away from light and avoid wearing it in full sun all day.

Is amethyst a precious stone?

No, it's a semi-precious (fine) stone. Historically prized, it is now abundant and therefore affordable; a high price is only justified for exceptional pieces.
