Kyanite stone has several names (notably cyanite), as it has been described by several geologists. The name “kyanite” was given by Abraham Gottlob Werner in 1789. Abraham Gottlob Werner is a German geologist and mineralogist who identified a great number of minerals. The term comes from the Greek “kyanos”, meaning “blue” (this Greek origin also produced the word “cyan”), referring to its colour. Kyanite will remain the official name, as it is recognized by the International Mineralogical Association. The second name attributed to this mineral is that of “disthène”, whose etymology comes from the Greek “di”, meaning “two”, and “destenos”, meaning “force”. This origin refers to its electrical properties. The name “disthène” is used mainly in France. It was attributed by René-Just Haüy in 1801. René-Just Haüy is a French mineralogist from the Oise who described numerous minerals from an impressive collection and founded geometric crystallography.

This mineral has other names around the world, including blue talc, sappare or sapparite (attributed by Ferdinand de Saussure), laminated beryl, munkrudite and kyanite zeolite. Until the 20th century, it was often confused with sapphire because of its very similar indigo colour. However, some legends attest that it was known since Antiquity for its particular electrical properties. Indeed, it could have been used as a compass, suspended by a hair. The sword of the Archangel Michael is said to be made of kyanite.

Its uses are rather limited due to its fragility.

  • It has been little used to make jewellery, as it can be easily damaged. The slightest shock with a harder material can damage it. However, some Central Asian peoples have used it to set jewellery to take advantage of its extraordinary blue-green lustre. Nowadays, it is used to adorn jewellery, but requires special care. It is used in particular as a birth crystal. Depending on its properties, compatible zodiac signs, it corresponds to people born in the month of September.
  • Currently, it is mainly sought after by collectors and for its lithotherapy properties. For this purpose, it is cut in rectangular crystal or cabochon shape or preserved in its natural form.
    It is used in industry to make ceramic objects resistant to pressure and heat. This is because, kyanite stone, tlike all aluminium silicates, is a good refractory material, which is particularly resistant to heat.
  • It is depicted in paintings, especially in abstract paintings.


Geologically, kyanite stone belongs to the group of aluminium silicates. It is a metamorphic rock, i.e. it results from the transformation of sediments under the influence of very high temperature and pressure conditions. It often contains other minerals, such as iron, chromium, calcium, magnesium and aluminium. It comes in the form of long, flat, striated crystals. It has a splintery fracture, i.e. it has splinters, fragments when it is broken. Its lustre, the way it reflects light, is vitreous or pearly. The vitreous lustre has the transparency of glass while the pearly lustre is characteristic of minerals with a fine fibrous structure, which gives a smooth, silk-like shiny appearance. Each specimen has an unmistakable appearance depending on its composition.

Kyanite’s blue colour varies according to the proportion of chromium. It varies from cyan to violet and indigo, but can have a very wide range of colours, including green, yellow, pink, brown, grey, black or white. In the case of grey or black shades, the term “rhaeticite” is more often used.

SIts reputation of fragility, which makes it a rock little used in jewellery, is partially undeserved. Indeed, its hardness varies according to the direction of its elongation, due to its texture in long crystal planes. In the direction of elongation, it has a hardness of 7.5 on Mohs scale, which makes it comparable to the hardness of quartz and topaz. Conversely, in the plane perpendicular to its elongation, kyanite has a hardness of only 4.5, which means that it is easily scratched with a knife. There are deposits of kyanite almost everywhere in the world, but the most exploited deposits are found in Brazil, France, Italy and Nepal.



Kyanite crystal has considerable power from an energetic point of view. It is a stone of transmission and amplification of spiritual power. It can be used on an energetic level to bring healing and new balance, especially following a trauma or spiritual disorder caused by negative energies. It has protective properties, especially against stress and negative environmental energies. By promoting appeasement, it allows you to calmly find solutions to daily problems, especially through communication. Its calming power applies in the same way to the anxieties and fears whose cause lie in the past.

It brings self-confidence thanks to its balancing and soothing virtues. It allows you to cope with the ups and downs of life with serenity and truth by pushing back anguishes. It promotes in the same way a deep and restorative sleep, keeping away anxious ruminations. It thus enables you to look at yourself more objectively, to analyse your attitudes and to accept yourself more easily. It also encourages the discernment of truth, intuition and the interpretation of dreams. Its soothing virtues make it a valuable ally in freeing meditation from the parasite of the mind. Communication and creativity are thus freed from the negative energies that hinder them. From a vibratory point of view, it brings real benefits when used on 3 particular chakras: the 6th (3rd eye), the 5th (at the throat level) and the 4th chakra (at the heart level).


This mineral is a major tool in lithotherapy, bringing balance and purification to the body, thus contributing to its good health. It is an effective natural complement for medical treatments (without replacing it, as it is recommended for all stones in lithotherapy: all information on the stones does not constitute medical advice or information of a medical nature). Indeed, it acts on different organism systems.

  • It facilitates the healing of fractures and physical trauma by stimulating cellular reproduction.
  • It has an antiseptic power, preventing and limiting infections.
  • It helps to relieve bone pain.
  • It helps to regulate blood pressure.
  • It promotes deep, restorative and natural sleep, which is necessary to maintain good health and restore vital forces.
