It appears green under daylight or fluorescent light and changes to red or purplish-red under incandescent or candlelight. This phenomenon is known as the alexandrite effect. Hardness: Alexandrite is relatively hard, with a Mohs hardness rating of 8,5, making it suitable for use in jewelry. Refractive Index: The refractive index of alexandrite ranges from approximately 1,745 to 1,755, depending on its composition and origin. Specific Gravity: Alexandrite has a specific gravity of 3,68 to 3,74, which is a measure of its density. Crystal System: Crystallizes in the orthorhombic crystal system, usually forming prismatic crystals.

Chemical Formula: Its chemical formula is BeAl2O4, which indicates the composition of beryllium, aluminum and oxygen. Traces of Chromium: Alexandrite’s unique ability to change color is due to the presence of traces of chromium in its crystal structure. Chromium absorbs certain wavelengths of light, resulting in an observable color change. Other properties: Durability: Alexandrite is very durable, making it suitable for everyday wear in jewelry such as rings, earrings and necklaces. Transparency: It generally exhibits excellent transparency, allowing light to pass through it and exhibit a color changing effect.

How does alexandrite change color under different lighting conditions? Alexandrite changes color due to a phenomenon called the “Alexandrite effect.” This effect occurs due to the interaction between the chemical composition of the gemstone and the type of light it is exposed to. In natural daylight or fluorescent light, which contains a high proportion of blue and green wavelengths, alexandrite appears green or bluish-green. This is due to the fact that chromium ions within the crystal structure absorb light in the yellow and blue regions of the spectrum, while transmitting green light. In incandescent or candlelight, which have more red waves, alexandrite has a different color. Here, chromium ions absorb more green and blue light, causing the gemstone to appear red or purplish-red. This dramatic color shift from green to red under different lighting conditions is what makes alexandrite so valuable and charming. This color-changing property is highly prized in gemstones and adds to the attractiveness and uniqueness of alexandrite, making it a desirable choice for jewelry connoisseurs.

The stone was christened in honor of the heir to the throne, the future Emperor Alexander II.

History

Alexandrite was called the royal, imperial stone. He quickly became popular. The reformer Alexander II was remembered for the abolition of serfdom, but radical circles of society continued to consider him, as a representative of the supreme power, a fiend from hell, and in 1881, during another assassination attempt, the emperor was killed. This played a role in the history of alexandrite: the “name” stone became a symbol of the monarchy, and the center-right wing chose it as its talisman. The ring with alexandrite said more eloquently than words that this was a monarchist. Since such jewelry was worn by generals and the highest ranks of the army, after the First World War, which claimed the lives of thousands of Russian officers, alexandrite began to be called the widow’s stone.

Materials

Although modern mythology refutes such associations. Today, alexandrite is considered a stone of strong personalities, managers, as well as creative people who need a stimulus for inspiration. The stone has been perceived as an amulet for many centuries. Its unusual properties are evident. Modern mineralogists explain them by the special structure of the crystal lattice and various impurities, but once they seemed like pure magic. It is no coincidence that even in Leskov’s stories alexandrite is called the “Russian prophetic stone” and is associated with witchcraft. It’s all about pleochroism: alexandrite is a chameleon stone. It changes color depending on the lighting. In daylight it is bright green, but in artificial light, as if by magic, it turns purple-red. Previously, this effect was associated with shed blood and it was believed that if a sudden change in color occurs for no reason, then this is a clear sign of approaching danger. It is no coincidence that in ancient times alexandrite was worn by warriors, using it as a kind of radar. Alexandrites are mentioned in the ancient Indian epic “Mahabharata”. Scientists have correlated stones with similar properties that appear on the pages of the book with alexandrites. There, by the way, they are considered symbols of good luck and future prosperity. Domestic science classifies the stone from the ring of the Polovtsian Khan, whose burial was found in Zaporozhye, as the first known alexandrite. We are talking about the 19th century. However, the stone gained true fame only in the XNUMXth century, after it received its official name.

Pricing

Alexandrites are considered expensive stones, and some samples can even be compared in price to the “big four” (diamonds, rubies, sapphires, emeralds). Natural stones are rarely larger than three carats, and during mining the loss of raw materials is colossal. Only a few samples can be classified as gem quality stones. This affects pricing. Alexandrites can cost between 6 and 20 thousand dollars per carat. Moreover, stones are often sold to mineralogist collectors without even setting them into jewelry. The largest alexandrite in history is considered to be a Ural stone of more than 500 carats, found at the end of the 60th century. In the absence of a buyer capable of paying a fortune (and more than one) for it, the stone was then cut down and sold in parts. The largest currently known stone weighs more than XNUMX carats. The Smithsonian Institution in the USA and domestic museums, in particular the Museum named after. A.E. Fersman in Moscow, where a unique crystal with tee growths and twin stones is kept, forming a spectacular, large druse, a “family” of stones.

Place of Birth

Ural stones are considered the best. For a long time, alexandrite was generally known as an exclusively Russian stone. But in the 20th century, its deposits were discovered in other parts of the world: from the USA to Sri Lanka. However, Russian samples are still valued above all else. They have the purest color: both bright green and rich, blood red. Brazilian stones are relatively close to them. African stones fade into yellow and pinkishness. By the way, stones with veins often appear there, creating the iridescent effect of a cat’s eye (they are called cymophanes). Such stones are also in price. Indian ones are more blue and pale crimson. Alexandrite is the most expensive variety of the chrysoberyl mineral. They are trying to counterfeit it, but simple glass is easy to recognize. To begin with, natural stone has high hardness (8,5 on the Mohs scale) and density; it cannot be scratched so easily. Unlike glass.

Artificial analogues

There are artificially grown stones. Moreover, scientists from different parts of the world are taking the lead in growing artificial alexandrites from each other. The Soviets are considered the pioneers, with laboratory experiments in the 1970s. Their stones are called Czochral stones, after the name of the scientist who invented the technology. Americans are also participating in the race. Be that as it may, it is really extremely difficult to distinguish artificially grown crystals from natural ones without special equipment. Also, corundum enriched with vanadium impurities is often passed off as alexandrites (most of the Soviet jewelry with “Alexandrites” is just like this). But they provide only a pale semblance of authentic pleochroism.

Lithotherapy

Lithotherapists are confident that the chameleon stone helps with blood diseases and those associated with them. For example, it can cure varicose veins. It also helps to open the heart chakra, which means establishing interpersonal relationships and finding balance between the power of the mind and the world of feelings. Helps against alcoholism!
