ANDALUSITE STONE: ITS HISTORY, ORIGIN AND COMPOSITION, AND ITS LITHOTHERAPEUTIC PROPERTIES AND VIRTUES

HISTORY OF ANDALUSITE STONE

Originally named « red-violet adamandin feldspar », this mineral was discovered in 1789, on granite rock samples from Imbert, located near Montbrison in the Forez region, by a French mineralogist and crystallographer named Jacques Louis de Bournon. In 1798, Jean-Claude Delamétherie, an 18th-century French naturalist, mineralogist, geologist and paleontologist, believed that the samples came from Andalusia in southern Spain. The stone was then given the name Andalusite, dedicated to its origin.
Later, it was discovered that the mineral actually came from El Cardoso, in the province of Guadalajara. In spite of its true origin finally determined, Andalusite kept the name which was given to it for a long time.

Andalusite stone consists of polymorphic crystals, in the shape of prisms with four corners or a radial agglomerate. Its colour varies between pink and brown, with grey, green and red hues. It can be opaque, translucent or even transparent. Depending on the perspective, the beautiful vitreous aspect of this stone allows it to absorb different waves of light. This is called pleochroism.

There are different varieties of Andalusite stones, two of the most important of which are used mainly as gems, therefore as fine and precious stones, to be placed in your house, or as ornaments, to be kept with you, as a jewel such as a bracelet :

  • Viridine, which is dark green.
  • And Chiastolite, which is dark-coloured, with an inclusion that looks like a black cross caused by its carbon and clay components.

Andalusite, Sillimanite and Kyanite stones are polymorphic, and belong to the silicate group. They contain alumina, which makes them refractory. In contact with pressure or a change in temperature, metamorphism takes place, i.e., the minerals change shape, thus serving as indicators of conditions. Because of its virtues in relation to pressure and temperature, this stone is part of the composition of the different minerals used in construction. In particular, it can be used to make thermal and electrical insulators, as well as ceramic utensils that are highly resistant to acids.

ORIGIN AND COMPOSITION OF ANDALUSITE STONE

Andalusite stone comes from a variety called Silicate, which is a subgroup of the nesosubsilicates. It is a salt that combines silicon dioxide with other metal oxides, such as alumina, thus including aluminum, magnesium, iron, calcium, potassium, sodium and many other elements. These components make this stone a refractory mineral that has a high resistance to thermal shock, making it an ally of the metallurgy industries. The stone’s trimorphs are Kyanity and Sillimanity. It is a mineral species. It can be found in regional metamorphism, either in schists or gneisses, but also in certain pegmatites or quartz-andalusite veins. About 25% of its world production is located in Glomel, Brittany. The gems of this stone are quite rare and very dichroic, which often gives it tones ranging from an olive to reddish tint depending on the angle of observation. These gems are found in the state of Minas Gerais, Brazil and also in Mogok, Burma. A 28.3-carat faceted stone is on display at the Smithsonian Institution in Washington, D.C., and a 40-carat faceted stone at the National Museum of Natural History in Paris.

To admire this so-called Andalusian in its natural environment, there are numerous deposits in the world. But in France, Brittany has been rich in stone for decades. Sedimentary rocks were formed with the accumulation of sediments. In the Côtes d’Armor, the Erquy Sandstone, which is rich in quartz, emerged from a succession of layers of sand. Metamorphic minerals were formed by the internal movements of the Earth. Slate, schist and gneiss were born this way. It is possible to go and contemplate slate schist quarries in the Montagnes Noires and in the Monts d’Arrée region.

Viridine or viridite, is a manganesiferous variety of andalusite. It is named so by Jules Gosselet, a French geologist, university professor and paleontologist, because of its colour, which is a rather bright green. It is located in many countries. It can be found in Western Australia, Wallonia in Belgium, Bahia in Brazil, Hesse in Germany, Greece or more precisely in Eastern Macedonia and Thrace, Sri Lanka in the Province of Sabaragamuwa, Sweden in Norrbotten County and Skane County, and even in Arizona and New Mexico in the United States. Chiastolite is a stone with shades of dark brown to black and is also a derivative of the so-called Andalusian stone. EIt is composed of dark inclusions of carbon and clay. When it is cut perpendicular to the axis of its prisms, it has an inclusion with the appearance of a black cross, which explains its other name ”cross stone”. Formerly called macle or crucite, the name has been preserved in heraldry. It was also discovered by Delamétherie. Deposits of this stone can be found in many places in the world. In France, they are located in Finistère, in the Parc-au-Duc in Plourin-lès-Morlaix, as well as in Plouigneau, the place being more precisely called Le mur.

At the Maison des minéraux de Crozon in Sainte-Brigitte, which is a museum, we can observe blocks of rocks, each as resplendent as the next. La Maison de Crozon then houses this stone known as protective, composed of white markings with yellow reflections which adopt various paces, lines representing arrowheads, lozenges, cross pattée or Maltese cross. The heraldic macle shape, perfectly traced, as if sculpted in stone, is not the most frequent, but the most spectacular. The Rohan castle, located in Sainte-Brigitte, was inspired by large mineral crystals for the macle of its coat of arms. These crystals come from the land surrounding the feudal mound of Alin and Rohan in the Porthoët.

LITHOTHERAPEUTIC VIRTUES AND PROPERTIES OF ANDALUSITE STONE

ANDALUSITE STONE’S PSYCHOLOGICAL BENEFITS

Andalusite stone allows you to find a certain balance at the material, spiritual and emotional level. Concerning the spiritual level, this stone helps you to discover your identity and your life’s mission. It helps you to fight, soothe, calm and remove fears. By promoting self-confidence and soul generosity, it accompanies you in difficult choices and important crossroads of life. It also helps you to improve your mind in order to take things into account by allowing yourself to think big while remaining realistic, and thus to orient yourself in the right direction for the future. Its sister, Chiastolite, has similar effects, in addition to having the reputation of being a protector for centuries. Thanks to its patterns, it strengthens and calms the nerves, soothes fears and stabilizes the mind.

During meditation, they facilitate stable astral travel and extra-corporeal travel. They stimulate intuition, simplify introspection for better self-knowledge. Concerning the heart chakra, cosmic and telluric energies find a balance. For the third eye chakra, parasitic thoughts disappear to give way to extra-sensory perceptions and remove deep terrors. All stones in the form of a smooth pebble must be purified regularly from the moment you possess it. Purification of Andalusite is carried out every three days preferably in the dark, in running or distilled water. This frequency is due to the negative energies that it absorbs to reduce their impact on the body. It must be cleared of all psychic waste or negative energies. It must then be recharged by placing it on a pile of quartz and in sunlight or moonlight.

ANDALUSITE STONE’S PHYSICAL BENEFITS

In lithotherapy, Andalusite stone and its protective twin offer comfort to people suffering from digestive problems. They limit gastric acidity and soothe intestinal difficulties. These stones, being beneficial for bones and joints, help to reduce gout attacks and joint pain. In addition to strengthening and calming the nerves, this stone, named from Spain, has a regenerative action for people in a situation of physical and mental exhaustion. It promotes recovery and rest. For young mothers who are breastfeeding, this gem is a good stimulant for lactation.

You should not dispense with consulting your doctor or even obtaining medical treatment if necessary, even if you notice a physical improvement. All health stones act on the duration of contact with you. You should then use them on a daily basis. You can display them in a room of the house, ideally your bedroom, or wear them as jewellery, such as bracelets, earrings or pendants to keep them close to you at all times.
