History and Lore
The history of alexandrite is as fascinating as its appearance. The gemstone was first discovered in 1830 in the Ural Mountains of Russia. At the time, Tsar Alexander II was the heir apparent to the Russian throne, and the discovery of a gemstone with colors mirroring the national military colors of imperial Russia—green and red—was seen as an auspicious omen. In honor of the young Tsar, the gemstone was named alexandrite. This event marked the beginning of its journey into the annals of gemological history.
Alexandrite quickly gained popularity in Russia and was often worn by nobility and royalty. The gemstone's rarity and its association with the Tsar contributed to its prestige. It was not only a symbol of good fortune but also a representation of the wearer's status and power. Over time, alexandrite's allure spread beyond the borders of Russia, captivating gem collectors and jewelers worldwide.
In the 20th century, alexandrite found a new cultural significance as a June birthstone. Alongside pearl and moonstone, it represents those born in June and is believed to bring unique benefits to individuals associated with this month. Furthermore, alexandrite is recognized as the traditional 55th wedding anniversary gemstone, making it a meaningful and enduring symbol of love and commitment.
Geological Formation and Sources
Alexandrite is a variety of the mineral chrysoberyl, with a chemical composition of beryllium, chromium, and aluminum oxide. Its unique color-changing properties are due to the presence of trace amounts of chromium, which replaces some of the aluminum in the crystal structure. This substitution is what allows the gemstone to exhibit a green hue in daylight and a red hue under incandescent light. The degree of color change can vary, and the most prized specimens display a vivid green to bluish green in daylight and an intense red to purplish red in incandescent light.
The formation of alexandrite requires specific geological conditions. It typically forms in metamorphic rocks, where the presence of beryllium and chromium is essential for the creation of the gemstone. The process involves the interaction of pegmatites and mafic rocks, leading to the development of alexandrite crystals. These crystals can be prismatic and elongated or tabular and short, and they often display prominent striations and twinning. Contact and penetration twinning are common in chrysoberyl crystals, and these can create intricate patterns and rosettes within the gemstone.
The primary sources of alexandrite are the Ural Mountains in Russia, where it was first discovered. However, due to the depletion of these original deposits, alexandrite is now also found in other locations around the world, including Brazil, Sri Lanka, and Madagascar. These regions have contributed to the global supply of alexandrite, ensuring that this rare gemstone remains available to collectors and jewelers.
Gemological Properties
The gemological properties of alexandrite are as distinctive as its appearance. With a hardness of 8.5 on the Mohs scale, alexandrite is relatively durable and resistant to scratches. This hardness makes it suitable for use in various types of jewelry, including rings, earrings, and pendants. However, its toughness is not as high as its hardness, meaning that it can be susceptible to chipping or cracking if subjected to impact or high heat.
The refractive index of alexandrite ranges from 1.74 to 1.78, contributing to its brilliance and luster. This refractive index, combined with its color-changing properties, makes alexandrite a highly desirable gemstone. The gemstone's clarity can vary, with some specimens exhibiting inclusions that can affect their overall appearance. However, these inclusions are often considered part of the gemstone's character and can even enhance its value by indicating its natural origin.
Alexandrite can also exhibit a phenomenon known as chatoyancy or the cat's-eye effect, where certain inclusions create a band of light across the surface of the gemstone. This effect is particularly striking in alexandrite and adds to its allure. The combination of these gemological properties makes alexandrite a unique and valuable addition to any gemstone collection.
Symbolism and Metaphysical Beliefs
Alexandrite is not only admired for its physical properties but also for its rich symbolism and metaphysical attributes. Known as the "Chameleon Stone," alexandrite represents wisdom and good fortune. Its ability to change color is often interpreted as a symbol of adaptability and the ability to embrace change. This duality of red and green—passion and peace—encourages individuals to find balance and harmony in their lives.
In Russian culture, alexandrite is associated with personal pride and prestige. It is believed to bring good luck and is often worn as a talisman to attract positive energy and emotional balance. The gemstone is also considered a heart chakra cleanser, promoting emotional well-being and spiritual strength. Wearing alexandrite is thought to enhance one's ability to navigate life's challenges with grace and resilience.
From a metaphysical standpoint, alexandrite is believed to have restorative healing energy. It is said to support the pancreas and spleen, aiding in detoxification and promoting healthy blood circulation. These properties make alexandrite a popular choice for those seeking to improve their overall health and vitality. Additionally, alexandrite is used in Feng Shui and other spiritual practices for its fortune-bringing qualities, making it a versatile and powerful gemstone.
Care and Cleaning
Due to its unique properties, alexandrite requires special care to maintain its beauty and integrity. As a gemstone with a hardness of 8.5 on the Mohs scale, alexandrite is relatively durable but can still be susceptible to damage if not handled properly. It is important to avoid exposing the gemstone to high heat, as it may crack or become damaged. Ultrasonic and steam cleaners should be avoided, as they can potentially harm the gemstone.
The best method for cleaning alexandrite is to use warm, soapy water with a soft brush. This gentle approach will effectively remove any dirt or debris without causing harm to the gemstone. It is also recommended to rinse the gemstone thoroughly with clean water after cleaning to ensure that no soap residue remains. For those who wish to recharge the gemstone, placing it in sunlight or smudging it with incense is believed to wash away stagnant energy and restore its positive properties.
When storing alexandrite, it is advisable to keep it in a soft pouch or a lined jewelry box to prevent scratches and damage. Avoid storing it with other gemstones, as the hardness of alexandrite can cause scratches on softer stones. Additionally, it is important to remove alexandrite jewelry before engaging in activities that may expose it to impact or abrasion, such as sports or manual labor.
