Heulandite is a soft zeolite mineral that forms crystals in volcanic rock. It's pink, peach or white and is mostly a collector's stone, not something for everyday wear.

BOILING STONE
The zeolite family, heulandite included, was named by Axel Cronstedt in 1756 from Greek words for 'boiling stone,' after a mineral that steamed when heated.
BELOW 100 °C
Heulandite forms below about 100 °C, so finding it in sedimentary rock points to shallow burial.
What it is
Heulandite is a zeolite that grows as glassy, coffin-shaped crystals in cavities of volcanic rock. It is colorless, white, pale pink, peach or orange, and is sold as collector specimens.
What gives it its color
Heulandite is usually colorless or white; orange, brown, yellow, brick-red or green shades come from inclusions, with the green caused by celadonite.
Where it comes from
Heulandite comes from the Deccan Traps of Maharashtra in India (Pune, Jalgaon, Nasik), Iceland (Berufjordur, Teigarhorn), the Faroe Islands, Scotland and Italy's Fassa valley.
What's said about it
We could not trace a body of crystal lore specific to it. It is usually grouped with the other pale zeolites, as a gentle stone to keep and look at.
It's named for John Heuland, a collector who dealt in minerals in the 1800s. People keep it on a shelf or in a padded box.
How people wear or keep it: On a shelf, in a padded box, or on a desk.
In crystal practice
In the crystal tradition, heulandite is paired with the heart chakra, so practitioners rest it there during meditation or lie down with it in place for a few quiet minutes. Day to day, the same tradition suggests keeping it close: on a shelf, in a padded box, on a desk. People reach for it when they want calm, and many set an intention when they put it on. Most practitioners cleanse a new stone first (running water only if the stone can take it, otherwise smoke or moonlight) and set it aside now and then to rest.
These are beliefs people have held and still hold about the stone, reported as such. Nothing here is a promise or a medical claim. We sell stones as jewelry, not for these effects.

Care
- Soft and brittle, with perfect cleavage: it chips and splits easily, so it suits display rather than daily wear.
- Zeolites hold water in their structure, so keep it away from water and heat.
- Store crystal groups on a shelf or in a padded box, not loose with harder stones.
- Dust with a soft brush; do not soak or use cleaners.
How to tell what you have
- Real heulandite grows as glassy, coffin-shaped crystals with a pearly face, colorless, white, pink, peach or orange.
- It is soft (3 to 4 on the Mohs scale) and splits easily; stilbite is a close look-alike that only lab optics separate.
Questions people ask at our table
What is heulandite?
A zeolite, a group of water-bearing minerals that crystallize in the gas cavities of volcanic rock. It is named for a nineteenth-century collector.
Is it used in jewelry?
Rarely. It is soft, brittle and splits along one direction, so it is mostly a collector's mineral.
Where does it come from?
The best-known pink and peach pieces come from the Deccan Traps of India near Mumbai. It also occurs in Iceland, the Faroe Islands, Scotland and Italy.
Is the color natural?
Yes, the pink and peach shades are natural. The green and brown tones are often from tiny inclusions of another mineral.
Do you carry heulandite?
No. Pink aventurine and howlite are the carried stones that give a pale pink or white look, and scolecite and apophyllite are related zeolites.
