# Howlite: virtues, calm and sleep

Published on **25/07/2026** · By **Sébastien Joumel**

In brief

**Howlite is a white stone veined with grey, soft (3.5 on the Mohs scale), which tradition links to calm and sleep.** Often dyed blue to imitate turquoise, it calls for care when buying. Here's what it is and how to choose it.

## What howlite is

Howlite is a **calcium borate**, matte white veined with grey, with a "porcelain" look. It is **soft** (hardness 3.5 on the Mohs scale) and porous, which makes it easy to dye. Indeed, **blue-dyed howlite** is often sold, wrongly, as "turquoise" or "turquenite".

## Meaning & virtues in tradition

In crystal tradition, howlite is a stone of **calm**, patience and help with **sleep**. **These virtues are traditions and beliefs: they are not scientifically demonstrated and replace no medical advice** (see sources).

## How to wear and choose it

Soft and porous, howlite wears quickly: keep it for **occasional wear** (pendant, low-impact bracelet) and away from water and cosmetics. When buying, know that a cheap, bright-blue "turquoise" is very often dyed howlite. See our [natural stone jewellery guide](https://meilleures-bijouteries.fr/en/guides/natural-stone-jewellery-guide/).

## Care

A barely damp soft cloth, no soaking (it's porous), no chemicals or ultrasonics. Store it away from scratches.

## Frequently asked questions

What are the virtues of howlite?

Tradition links it to calm, patience and help with sleep. These virtues are beliefs, with no scientifically demonstrated effect, and replace no medical advice.

Is howlite fake turquoise?

Howlite is a real stone, but it is often dyed blue and sold wrongly as turquoise. A cheap, bright-blue "turquoise" is very frequently dyed howlite: ask for the true nature of the stone.

Can howlite be worn every day?

Not advisable: with a hardness of 3.5, it is soft and porous, so it scratches and wears quickly. Keep it for occasional wear and away from water and cosmetics.
