What is staurolite?

Staurolite is an iron aluminium silicate that forms in rocks transformed by heat and pressure, such as mica schists. It is reddish brown to blackish, almost always opaque, and has a dull to vitreous lustre. Its name comes from the Greek stauros, "cross", and lithos, "stone".

Its distinctive feature is twinning: two crystals intergrow at a precise angle. When they cross at 60°, the result is an X; at 90°, a true Latin cross. Nature has thus shaped these crosses without human intervention. For geologists, staurolite is an "index mineral": its presence gives information about the temperature and pressure the rock has undergone.

Where does it come from?

It is found all over the world. In the United States, Georgia (Fannin County) has made it its official state mineral, and Virginia is home to a state park called "Fairy Stone". Staurolite also occurs in Switzerland (the Lepontine Alps), Norway, Russia and France, notably in Brittany, where its crossed crystals have long circulated as small local curiosities. Loose crystals are found in the soil, freed from the rock by erosion.

History and folklore

Several legends surround the "fairy crosses". According to a story widespread in Virginia, fairies wept on learning of the death of Christ; their tears, as they fell, turned into small stone crosses. In Europe and America, these crystals were carried as amulets or as small devotional objects. These are popular traditions that vary from place to place, with no guaranteed historical value.

Symbolism and traditional correspondences

The cross shape has inspired symbols of protection, faith and luck in various cultures. Contemporary authors also see in it a symbol of the link between heaven and earth, or between the paths that cross in a life. These readings are cultural and personal: they rest on no proof, and the stone protects against nothing.

Respect the religious value the cross may have for some people: staurolite may be offered as a souvenir without being presented as an object of worship.

How to use it

As a pendant or charm: a small drilled or set crystal, worn as a souvenir.
As a pocket stone: easy to slip into a bag or onto a keyring.
Placed in a corner for meditation or on an altar.
As a gift: to offer for a journey, a christening or a birth, with a short card explaining the origin of the name.

No stone replaces medical advice or professional support.

Care and cleansing

With a hardness of 7 to 7.5, staurolite is resistant. It is not affected by water, sun or everyday household products. A rough crystal can, however, chip on a knock, and very fine crosses break easily.

Wash in lukewarm water with a soft brush.
Avoid knocks on the arms of the cross.
Symbolic purification: running water, gentle smoke, sunlight or moonlight (see cleansing and recharging your stones).

Recognising genuine staurolite

A genuine staurolite cross is a natural crystal: its angles are always 60° or 90° and its surfaces carry fine striations and inclusions. "Crosses" that are too perfect, with equal arms, may be moulded in resin, ceramic or glass paste; crosses made from other stones also exist. The colour of a genuine piece is matt brown, sometimes with traces of mica schist. A reliable seller states the origin (Virginia, Georgia, Russia, etc.).

Observing your own crosses

If you find a cross in nature, never force it: the crystals separate at the slightest pressure. Look at it with a magnifier: you will see that the two arms are in fact two prismatic crystals passing through each other. The original rock, a mica schist, is a layered rock, glittering with small mica crystals.

In protected places (parks, reserves, listed sites), collecting is prohibited. Find out before you take anything. Commercial crosses come from authorised deposits.

How to choose one

Choose according to the crispness of the cross and the strength of the arms. Crosses at 90° are rarer and more sought after than 60° X shapes. It pairs with grounding stones such as red jasper or garnet, with which it often shares its original rock (mica schist).
