IOLITE STONE: ITS HISTORY, ORIGIN AND COMPOSITION, AND ITS LITHO THERAPEUTIC PROPERTIES

History of Iolite stone

Iolite, or cordierite, is a stone that belongs to the silicate family. It contains high quantities of magnesium, silicate and aluminium. It is a photo-reactive rock that cannot be dissolved in water or acid and is fire-resistant. Although it appears to the naked eye to have a rather purple tint, a vitreous lustre with blue and yellow light can be seen with optical equipment. The largest natural cut crystal can be observed at the British Museum. It weighs 855 carats.

Iolite takes its name from the Greek ‘ios’ meaning purple in reference to its intense colour. It was first used by the Vikings. According to legend, famous explorer Ragnar Lodbrok used it as a filter to spot sunlight when the weather was overcast. Even today, some call it the ‘Rock of the Vikings’ or ‘rock compass’, in reference to this practice that was perhaps common among Scandinavian explorers. According to Greek oral tradition, this transparent crystal was considered sacred and was used by a cult devoted to Athena, the goddess of war and wisdom.

In 1809, renowned French geologist Louis Cordier gave it the name ‘dichroite’. This name is a direct reference to the pleochroism of this rock of great hardness (its photo-reactive ability to change hue according to the axis of observation), as it designates ‘two colours’. When it was described by the mineralogist Lucas in 1813, it was named cordierite, paying tribute to Louis Cordier.

Even today, iolite remains difficult to identify for gemologists and jewellers as it can easily be confused with other stones of the silicate family. In particular, it is often equated with amethyst, blue quartz, serpentine or tanzanite. This natural crystal is, for the most part, faceted or cut into cabochons. This cut highlights the rock’s ability to change hue depending on the axis of observation. As iolites over 5 carats are of great rarity, it is generally easier to find gems of 1 to 5 carats.

Origin and Composition of Iolite Stone

Like all mineral species that belong to the silicate group, the major component of this raw gem is silicate. The formula for this crystal without inclusions is Al3Mg2AlSi5O18. Traces of Manganese, Iron, Carbon, Sodium and Potassium can be observed in its composition. This rock’s crystals can reach up to 18 cm in size.

This scarce mineral can be seen in rocks of argillaceous material and in certain types of shale. It appears primarily in clay sediments that have undergone a transformation when heated. It is considered of chemical nature and is particularly rich in aluminium. Its presence can occur in iolite’s early stages of metamorphism (similarly to haematite) or at a later stage. Iolite can also be found in magmatic rocks, such as pegmatites or granitic rocks, as well as from high-level regional metamorphism.

Its fracture is subconchoidal to conchoidal. On thin layers, iolite stone has a rather low birefringence. When it is present in altered materials, it becomes pinite, turning into micro-crystalline aggregates of muscovite or clorite. To find cordierite, it is often preferable to look for the presence of pinite alteration near yellow pleochroic fractures or halos with haematite or zircon inclusions.

This rare mineral is often associated with other rocks of the same type as well as the following minerals: biotite, corindon, haematite, muscovite, sillimanite, potassium feldspars, andalousite, etc. Its primary deposits are on the Southern Hemisphere, including Brazil, India, Sri Lanka, Madagascar and Myanmar.
