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

History of Alexandrite Stone

Alexandrite is formed from volcanic lava flows. It was discovered in 1830 by miners in the Tokovaya emerald deposits in Russia’s Ural Mountains. But it was not until 1842 that the Finnish Nordenskiöld gave it its official name, in honour of Tsar Alexander II, whose birthday was being celebrated at the time. Due to its colour variations which range between red and green which sometimes feature darker hues (two colours reminiscent of the Russian Imperial Army’s uniforms) alexandrite stone quickly became the symbol of Tsarist Russia, in honour of the Tsar. The stone was so successful, particularly in the manufacturing of jewlerry for the Tsarian court, that the Russian mines were overexploited and quickly depleted, leading to a shortage. It was not until decades later, at the end of the 20th century, that new deposits were identified in Sri Lanka, Brazil, the State of Minas Gerais, Tanzania, at Mozambique’s borders, and in Madagascar.

Along with Cat’s Eye, alexandrite is a highly valued variety of chrysoberyl stone. This gem features different facets whose shades can shift from beautiful transparent yellow to beautiful brown-green yellow. Similar to other gem varieties such as emerald or ruby, the primary characteristic of alexandrite is to change shades depending on the level of light to which it is exposed, whether natural or synthetic. It changes from a vibrant shade of blue and green when exposed to natural light, and to a purplish red when placed under synthetic light. These hue variations earned it the nickname “emerald of the day, ruby of the evening”. They are due to the material from which this stone is composed of, namely aluminium oxide, beryllium and chromium. It is, moreover, a very hard stone as its index is 8.5 on the Mohs scale.

This rare and high-quality mineral was particularly prized by Master gemologist George Kunz of Tiffany who purchased a large quantity of them to create numerous rings of all sizes from the late 19th century to the beginning of the 20th century. It also was highly appreciated by the English during the Victorian era.

Its primary benefits were identified during the 19th century. Russian author Nikolai Leskov (1831 – 1895) attributed it the power to strengthen intuition in one of his short stories, helping one to predict the future. French writer Eliphas Levi (1810 – 1875), a former clergyman and a great figure of the occult, believed that alexandrite could, in particular, improve arterial and venous circulation. Its popularity in Russia has not waned as it is considered a source of imagination and creativity. Thanks to its varying shades, it helps to alleviate sadness and emotional excess by providing confidence and hope. Physically, it is considered capable of improving the effectiveness of treatments in the case of prolonged physical or psychological dysfunctions. Finally, it can attract luck and romantic fulfillment to the wearer.

Along with pearl and moonstone, alexandrite is one of June’s birthstones.

Origin and Composition of Alexandrite Stone

Like chrysoberyl stone and cat eye, alexandrite consists of a very particular olivine crystalline structure whereby, the Be2+ cations occupy the tetrahedral sites while the Al3+ cations occupy the octahedral sites. In addition, the average bond length are: Be-O = 1,638 Å et Al-O = 1,914 Å.

Alexandrite’s colour adjusts according to the light level. It thus becomes blue-green in daylight, pink-red when placed under artificial light and transparent grey under fluorescent light. Its ability to shift from magenta to a shade between green and light blue or to tones with yellow and orange is as a result of its strong pleochroism. Pleochroism is an optical principle that means that a stone has the ability to absorb several light spectra depending on the axis on which they cross its various facets.

This stone is called trichroic in optical terms, as it has three secondary shades that appear according to the axis and origin of the light. It varies between shades of blue-green, reddish or yellow. It also features a white streak.

The most astonishing alexandrite was found in the Russian deposits which are today depleted. The stones extracted from Brazil’s deposits are not of equivalent quality and are not always pleochroic. The most beautiful alexandrite stones can sell at higher prices than diamonds, depending on the amount of carats and their size. This gem also has a slightly lower hardness index than ruby or sapphire. This stone is very resistant to heat and shock. It has a vitreous lustre and can appear transparent or even translucent.

This rare stone is type II, i.e. it can have visible inclusions of liquid or solid matter, especially when its weight exceeds its carats. These inclusions do not, however, diminish its beauty or quality, but can reduce the value of this stone. The largest stone was mined in Sri Lanka and was valued at 1846 carats.
