For those born on June 18th, Alexandrite is more than just a birthstone; it is a cherished gemstone that embodies the essence of adaptability and change. This rare and captivating stone is named after Tsar Alexander II of Russia, in honor of his ascension to the throne in 1830.

This article will delve into the historical significance of Alexandrite, its geological formation, gemological properties, and the metaphysical beliefs associated with it. We will also provide practical advice on how to care for this delicate gemstone.
History and Lore
Alexandrite's history is intertwined with the cultural and historical fabric of Russia. Discovered in the Russian Empire in 1830, the gemstone was named after Tsar Alexander II, whose ascension to the throne coincided with its discovery. This serendipitous event imbued the stone with a sense of royalty and prestige, making it a symbol of good fortune and imperial power. The stone was found near an emerald mine, and its initial discovery was met with great enthusiasm due to its unique color-changing properties.
The lore surrounding Alexandrite is rich with symbolism. It is often referred to as the "happy stone" and the "jewel of transition," reflecting its ability to change color. This metaphorical transformation has made it a popular choice for those seeking to embrace change in their lives. The stone's color change is not only a physical phenomenon but also a symbol of emotional and spiritual transformation. In many cultures, Alexandrite is believed to bring balance and harmony, making it a favored gemstone for those navigating significant life changes.
Geological Formation and Sources
Alexandrite is a chrysoberyl variant, composed of beryllium aluminum oxide (BeAl₂O₄). Its color-changing property, known as the alexandrite effect, is due to the presence of trace amounts of chromium within the crystal lattice. This element interacts with light in a way that causes the stone to appear green in daylight and red under incandescent light. The phenomenon is a result of the absorption and re-emission of light at different wavelengths, creating a mesmerizing visual effect.
The primary source of Alexandrite is Brazil, where it is found in the Ubatuba region. Other notable sources include India, Sri Lanka, and Madagascar. The formation of Alexandrite occurs under specific geological conditions, typically in metamorphic rocks where beryllium and aluminum are present. The process of formation is complex and requires a precise combination of temperature, pressure, and chemical composition, making Alexandrite one of the rarest gemstones in the world.
The rarity of Alexandrite is further compounded by the difficulty in mining and cutting the stone. Due to its hardness on the Mohs scale (8.5 to 9), Alexandrite is relatively durable but still requires careful handling to avoid damage. The gemstone is often cut in a cushion or emerald cut to maximize its brilliance and showcase its color-changing properties. The quality of the cut significantly affects the stone's appearance, with well-cut Alexandrites exhibiting a more pronounced and vibrant color change.
Gemological Properties
Alexandrite possesses a unique set of gemological properties that distinguish it from other gemstones. Its color change is the most notable feature, but other characteristics also contribute to its desirability. The stone has a refractive index of 1.74 to 1.78, which means it bends light in a way that enhances its brilliance and sparkle. This refractive index is relatively high, allowing Alexandrite to display a lively play of light when properly cut.
The hardness of Alexandrite is another important factor in its gemological profile. With a hardness of 8.5 to 9 on the Mohs scale, it is one of the harder gemstones, making it suitable for everyday wear in jewelry. However, it is still susceptible to scratches from materials like diamonds and sapphires. Therefore, it is advisable to store Alexandrite separately from these harder gemstones to prevent damage.
Clarity is another aspect to consider when evaluating Alexandrite. High-quality Alexandrites are typically free of visible inclusions, which enhances their overall appearance. However, some inclusions may be present, and these can add character to the stone. The presence of inclusions should be assessed in the context of the stone's overall quality and beauty.
In terms of color, Alexandrite is most prized for its vivid green and rich red hues. The intensity of these colors can vary depending on the lighting conditions and the presence of trace elements. The green hue is particularly striking in daylight, while the red color is more prominent under incandescent light. This dual-color display is a defining feature of Alexandrite and contributes to its allure.
Symbolism and Metaphysical Beliefs
Beyond its physical properties, Alexandrite is rich in symbolism and metaphysical beliefs. It is often associated with transformation, renewal, and emotional balance. The stone's ability to change color is seen as a metaphor for the adaptability required to navigate life's challenges. This symbolism makes Alexandrite a popular choice for those undergoing significant life changes or seeking personal growth.
In many cultures, Alexandrite is believed to have healing properties. It is thought to promote emotional stability and help individuals process difficult emotions. The stone is also associated with intuition and spiritual insight, making it a favored gemstone for those on a spiritual journey. Some believe that Alexandrite can enhance one's ability to make wise decisions and foster a deeper connection with the self.
The stone is also linked to the heart chakra, which is associated with love, compassion, and emotional healing. By working with Alexandrite, individuals can open their hearts to new possibilities and experiences. The stone is believed to help release negative emotions and promote a sense of inner peace and harmony.
In addition to its emotional and spiritual properties, Alexandrite is also associated with creativity and imagination. It is thought to stimulate the mind and encourage innovative thinking, making it a valuable tool for artists, writers, and other creatives. The stone is believed to enhance one's ability to see new perspectives and find creative solutions to problems.
Care and Cleaning
Proper care and cleaning are essential to maintaining the beauty and longevity of Alexandrite. Due to its hardness on the Mohs scale, the stone is relatively durable, but it still requires gentle handling. When cleaning Alexandrite, it is best to use a soft cloth and a mild detergent. Avoid using harsh chemicals or abrasive materials, as these can damage the stone's surface.
Ultrasonic cleaners should be used with caution when cleaning Alexandrite. While they can be effective for removing dirt and grime, they may also cause damage to the stone if used for extended periods. It is advisable to consult a professional jeweler for recommendations on the best cleaning methods for Alexandrite.
Storage is another important aspect of caring for Alexandrite. The stone should be stored in a separate compartment to avoid scratches from harder gemstones. A soft cloth or pouch can help protect the stone from dust and debris. It is also a good idea to periodically inspect the stone for any signs of wear or damage.
When wearing Alexandrite jewelry, it is important to avoid exposing the stone to extreme temperatures or sudden changes in temperature. Rapid temperature changes can cause the stone to crack or become brittle. Additionally, it is advisable to remove Alexandrite jewelry before engaging in activities that may expose the stone to impact or abrasion.
