What is sodalite?

Sodalite is a mineral from the feldspathoid family (related to feldspars, but poor in silica). It is a chlorinated silicate of sodium and aluminium, crystallising in the cubic system. Its name combines “soda”, meaning sodium, and the Greek lithos, stone: it refers to its composition. The rock is often massive, a deep blue crossed by white or pale veins and patches (calcite or feldspar). More rarely, it is colourless, grey, green or pink.

It was scientifically described in the early 19th century, based on specimens from the Ilimaussaq massif in Greenland. Today, the fine blue blocks destined for cutting come mainly from Canada (Ontario, Quebec), Brazil and Namibia; it is also found in Afghanistan, in Italy (Vesuvius) and even in France, in the Cantal. It is carved into beads, cabochons, spheres and eggs, and used as a facing stone.

Sodalite is also one of the minerals that make up lapis lazuli, alongside lazurite and pyrite, but on its own it forms a clearly distinct stone.

A stone that responds to light

Some sodalites are fluorescent: under an ultraviolet lamp they can glow orange. One variety, hackmanite, is said to be photochromic: its pale or pinkish tint can change in light and then return in the dark. This is a well-known physical phenomenon, with no link to any kind of “energy”. It makes sodalite fun to observe, especially for children curious about mineralogy.

Traditional symbolism

The deep blue has long evoked the night sky and reflection. In the modern tradition of stones, sodalite is associated with clarity of thought, measured speech and sincerity. It is often suggested to people who study, prepare a presentation or want to bring order to their ideas.

These are symbolic associations: they have no scientific value and do not replace personal work or medical advice.

How to use it

As a necklace or bead bracelet: sodalite is a classic jewellery stone with a clear colour.
On a desk: a sphere or small tumbled stone next to your computer or notebooks.
During meditation: held in the palm before speaking in public or to help focus.
As decoration: polished bowls, eggs or slices in a lovely blue.

Care and cleansing

With a hardness of 5.5 to 6, sodalite can be scratched by a steel point and may shatter under a hard blow. It cleaves, although the cleavage is poor.

Cleaning: soft cloth, slightly damp, then dry immediately. Avoid acids (vinegar, lemon, descaling products), which attack it.
Avoid long soaking and ultrasonic cleaners.
Light: as a precaution, do not leave it for weeks in full sun (some pieces may change shade).
Symbolic cleansing: gentle smoke, a while in moonlight, or selenite placed alongside it. Salt is not recommended.

Telling it apart from lapis lazuli and imitations

The most common confusion is with lapis lazuli: both are deep blue. Key points:

Lapis lazuli contains golden flecks of pyrite and patches of white calcite; its colour leans towards ultramarine.
Sodalite is more even, with white or grey veins and no golden flecks.
White stones or other rocks (howlite, chalcedony) can be dyed blue to look like sodalite: a colour that is too vivid, with no natural veining, or one that bleeds onto a damp cotton swab are warning signs.
Blue glass or glass paste can be identified by small bubbles and an overly perfect surface.

An honest seller states the name of the stone and any treatment it has undergone.

How to choose it

Choose a rich blue, harmonious white veining and an even polish. Sodalite is generally less expensive than lapis lazuli and remains very affordable. For beads, check that the holes are well centred and that there are no chips. It goes well with lapis lazuli, amazonite or clear quartz.
