Individuals born on June 18th are associated with the captivating gemstone, Alexandrite, a gem renowned for its remarkable color-changing properties and rich symbolism. While June boasts three traditional birthstones – pearl, moonstone, and alexandrite – Alexandrite holds a unique significance for those born on this specific date. This article delves into the history, geological origins, gemological characteristics, and cultural significance of this extraordinary gem.
History and Lore
Alexandrite’s discovery is relatively recent compared to many other gemstones. It was first unearthed in the Ural Mountains of Russia in the 1830s, coinciding with the ascension to the throne of Tsar Alexander II. In honor of the Tsar, the gem was named Alexandrite, forever linking its history to Russian royalty. The initial Russian deposits were of exceptional quality, producing stones with vivid color change, but these sources are now largely depleted.
Today, Alexandrite is found in Sri Lanka, East Africa, and Brazil, though these deposits often yield smaller stones or those with less pronounced color change. Notable Alexandrite specimens include the Whiney Alexandrite, weighing 17.08 carats, discovered in Brazil, and the Sauer Alexandrite, a massive 122,400 carats, also found in Brazil. The Smithsonian Institution also houses a significant Alexandrite specimen, weighing 65.7 carats, originating from Sri Lanka.
Geological Formation and Sources
Alexandrite is a variety of chrysoberyl, a beryllium aluminum oxide mineral. Its unique color-changing ability is attributed to the presence of trace amounts of chromium within its crystal structure. This chromium allows the gem to absorb different wavelengths of light depending on the illumination source.
The formation of Alexandrite requires a specific geological environment – the presence of beryllium, aluminum, chromium, and oxygen in metamorphic or magmatic rocks. The original Russian Alexandrites formed in pegmatite rocks within the Ural Mountains. Current sources, such as Sri Lanka, East Africa, and Brazil, also produce Alexandrite in similar geological settings. The gem is not mined in the traditional sense like diamonds or rubies; rather, it is found within rock formations and requires careful extraction.
Gemological Properties
Alexandrite’s most defining characteristic is its color change. In daylight or fluorescent light, it typically appears a vibrant green, reminiscent of emerald. However, under incandescent light, such as candlelight or lamplight, it transforms to shades of red or purplish-red. This phenomenon, known as the “alexandrite effect,” is highly prized by collectors and gemologists.
Beyond its color change, Alexandrite possesses other notable gemological properties:
- Chemical Formula: BeAl₂O₄ (Beryllium Aluminum Oxide)
- Hardness: 8.5 on the Mohs scale, making it a durable gemstone suitable for jewelry.
- Crystal System: Orthorhombic
- Refractive Index: 1.743 – 1.753
- Specific Gravity: 3.71 – 3.85
- Clarity: Alexandrite often contains inclusions, which can affect its clarity and value. However, some inclusions can contribute to the gem’s unique character.
Due to its rarity and unique properties, natural Alexandrite is often expensive. Lab-created Alexandrite, possessing the same chemical composition and color-changing properties as its natural counterpart, is a more affordable alternative.
Symbolism and Metaphysical Beliefs
Alexandrite is rich in symbolism, representing transformation, renewal, and resilience. Its color-changing nature embodies adaptability and the ability to embrace change. The gem is believed to promote balance, intuition, and self-awareness.
Historically, Alexandrite was associated with good fortune and prosperity. Some cultures believed it could bring luck in gambling and protect against negative energies. The stone is also linked to the heart chakra, promoting emotional healing and compassion.
Pearls, another June birthstone, also hold significant meaning. Pearls symbolize purity, innocence, and faith, and are often associated with the moon and water, embodying wisdom and serenity. The formation of a pearl, from an irritant transforming into a beautiful gem, is seen as a metaphor for overcoming adversity and finding beauty in challenges.
Care and Cleaning
Alexandrite’s hardness of 8.5 on the Mohs scale makes it relatively durable, but it still requires careful handling and cleaning. To maintain its brilliance, Alexandrite jewelry should be cleaned regularly with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the gem.
Due to its potential for inclusions, Alexandrite can be susceptible to fracture. Therefore, it’s important to avoid sudden temperature changes and impacts. Regular inspection by a professional jeweler is recommended to ensure the setting is secure and the gem remains in good condition. Pearls, being organic gemstones, require even more delicate care. They should be wiped clean with a soft cloth after each wearing and stored separately from other jewelry to prevent scratching.
June’s Trio of Birthstones
While Alexandrite is specifically linked to June 18th, the month of June traditionally recognizes three birthstones: pearl, moonstone, and alexandrite. Pearls, the oldest traditional option, symbolize wisdom and serenity. Moonstone represents emotional balance and is deeply connected to the divine feminine. Alexandrite, a more modern addition, captivates with its rare color-changing ability. This diversity allows individuals born in June to choose a gemstone that resonates with their personal energy and aesthetic preferences.
The colors associated with June birthstones are equally diverse. Pearls offer soft whites, creams, and pinks. Moonstone displays glowing whites with flashes of blue. Alexandrite, as previously discussed, shifts between green and red. This range of colors reflects the creative, nurturing, and spiritually curious energy often associated with the month of June.
Conclusion
Alexandrite stands as a remarkable gemstone, celebrated for its captivating color change, rich history, and profound symbolism. For those born on June 18th, it serves as a cherished emblem of transformation, renewal, and resilience. Whether adorning a ring, pendant, or other piece of jewelry, Alexandrite’s radiant beauty continues to inspire awe and admiration, illuminating the path of those who embrace life’s journey with grace and wonder. The unique combination of scientific properties and cultural significance solidifies Alexandrite’s place as a truly exceptional gem.
