Sodalite: Na8(Al6Si6O24)Cl2, Mohs 5.5 to 6. Brief water contact only.
The short answerSodalite is sodalite, in the feldspathoid group, Na8(Al6Si6O24)Cl2, Mohs hardness 5.5 to 6. It is used for clear speech, logic, calm, and associated with the Throat chakra. On care, the short version: brief contact with water only, and sunlight does no harm.
What sodalite actually is
Start with the mineralogy, because most of the bad advice about this stone follows from not knowing it. Sodalite is sodalite, in the feldspathoid group. On colour: The blue comes from sulfur in the structure, related to the mechanism in lapis lazuli, which is a close relative.
Where it comes from: Brazil, Namibia and Ontario in Canada. The Canadian material was named for a royal visit in 1901.

Hardness matters more than it sounds. The Mohs scale runs from talc at 1 to diamond at 10, and anything below about 5.5 can be scratched by ordinary window glass or by the quartz dust in everyday grit. At 5.5 to 6, sodalite is hard enough to handle daily wear without much trouble, though it will still scratch a softer stone it is stored against.
What sodalite is used for
Used where lapis would be used but more calmly: for saying the thing accurately rather than bravely, and for work that needs both thinking and talking. It is the usual recommendation for people who go blank under pressure.
In the shorthand most shops and books use, it is a Throat stone, and the three words attached to it most often are clear speech, logic, calm.
Water, sunlight and salt
This is the section that matters, and the one most pages get wrong. Cleansing advice is handed around as though every stone were the same mineral, and it is not. Here is what sodalite will actually survive.
Caring for sodalite
Method
Safe?
Why
Water
Briefly
Brief contact only. Dry it straight away rather than leaving it to sit wet.
Direct sunlight
Yes
Direct sunlight does no damage.
Salt or salt water
No
No salt, dry or dissolved. It is abrasive and it attacks softer and porous stones.
Moonlight
Yes
Harmless to every stone on this list, which is most of why it is the method that suits everything.
Smoke, sound or breath
Yes
Nothing physical touches the stone, so nothing can be damaged by it.
Buying sodalite without being had
Sodalite is routinely sold as lapis lazuli and it is much cheaper. The distinction is easy: lapis contains brassy pyrite flecks, sodalite does not and usually shows white calcite veining instead.
Two general rules that hold across the whole shop. If the price is far below everything else on the shelf of that size, something has been substituted or treated. And a stone sold with no locality at all is usually one the seller cannot trace, which in this trade often means tumbled, dyed and bagged somewhere a long way from where it came out of the ground.
The astrology people attach to it
Sodalite is usually linked to Sagittarius and Virgo, and to Mercury. Worth being straight about this: crystal and zodiac pairings are modern, they are not consistent between sources, and two reputable books will give you two different signs for the same stone. They are a useful organising idea rather than a tradition with a single lineage behind it.
If you want the part of this that does have a fixed method behind it, the Sun in Sagittarius sets out what that sign actually describes, and it is calculated from a date rather than assigned by a writer.
How people actually use sodalite
Pick one thing for it to mean. A stone with four jobs has none. Clear speech is enough.
Put it where the thing happens, not where it looks good. A stone for sleep belongs by the bed; a stone for nerve belongs in the pocket you will actually reach into.
Handle it. The whole mechanism such as it is runs on the object interrupting you and reminding you of the thing you decided. A stone in a drawer does nothing.
Clean it by whatever method the table above allows, when it feels due rather than on a schedule somebody else set.
A word on crystal elixirsPutting stones in drinking water is a popular practice and a genuinely risky one. Several common minerals are toxic, soluble or both: malachite is a copper carbonate, cinnabar contains mercury, galena is lead, and selenite simply dissolves. If you want to make an elixir at all, use the indirect method, with the stone in a sealed glass container standing inside the water rather than in it.
What a stone can and cannot doNo crystal treats an illness, and no controlled study has found that one does. What the practice reliably provides is a physical object attached to an intention, which is a genuinely useful thing: it is a reminder you can hold, and keeping something in your pocket that means one specific thing works the way any ritual works. Nothing on this page should be used in place of medical advice, and nobody should delay treatment for it.
If you want something built from your own details
Every piece of sodalite in the shop is the same stone with the same associations, which is both the appeal and the limit of it. A birth chart is the opposite: it is calculated from your date, time and place and it describes one person. If you do not know your birth time, this covers how to find it.
