The month of June is unique in the world of birthstones, offering a trio of distinct gems: the organic pearl, the ethereal moonstone, and the rare, color-changing alexandrite. While all three hold historical and cultural significance, those born on June 14th have a specific claim to one of the most fascinating minerals on Earth. Alexandrite, the modern birthstone for this date, is celebrated not only for its beauty but for its extraordinary optical phenomenon and its deep-rooted connection to Russian imperial history. This article delves into the specific properties, lore, and gemological identity of Alexandrite, while also acknowledging the broader birthstone family it represents.
The Trinity of June: Pearl, Moonstone, and Alexandrite
The identity of June's birthstones has evolved over time, culminating in a diverse selection that caters to a wide range of tastes and preferences. The traditional pearl, the newest addition alexandrite, and the mystical moonstone all share the honor of representing the month. This diversity is a hallmark of June's gemological character.
Pearls stand apart as the only gems created by living organisms. Formed within the soft tissue of a mollusk, their creation is a natural process of layering calcium carbonate, resulting in a lustrous, organic gem. They have been the primary birthstone for June for centuries, symbolizing purity and serenity. Moonstone, a variety of the mineral feldspar, is prized for its unique visual effect known as adularescence—a milky, bluish sheen that seems to float across the gem's surface as it moves. It is associated with emotional balance and lunar energy. However, it is Alexandrite that captures the imagination with its dramatic color change, a property that has cemented its status as a gem of mystique and duality.
The color palette of June's birthstones is remarkably broad. Pearls offer a spectrum from classic creamy white and soft pink to deep black. Moonstone typically presents in whites and translucent hues with its signature blue flash. Alexandrite, in its most prized form, displays a startling shift from a vibrant green in daylight to a rich red under incandescent light. This visual dynamism makes Alexandrite a particularly compelling choice for those seeking a gem with a hidden depth.
The Discovery of a Tsar's Gem: History and Origins
The history of Alexandrite is inextricably linked to the Russian Empire. The gemstone was first discovered in the Ural Mountains of Russia in 1834. The timing of this discovery was serendipitous, coinciding with the coming-of-age celebration of the future Tsar Alexander II. In his honor, the new mineral was named "alexandrite," immediately bestowing upon it a regal heritage and an association with prestige and power.
Initially, the gem gained rapid favor among the Russian aristocracy. Its unique color-changing ability, which mirrored the national military colors of imperial Russia—green and red—was seen as a powerful symbol. The stone became a celebrated treasure of the Russian court. However, the original Russian mines that produced these gems eventually became depleted, leading to widespread concern that Alexandrite would become extinct and disappear from the market. This period of scarcity only enhanced its allure and value.
Fortunately for gem enthusiasts, subsequent discoveries in Brazil revitalized the global supply of Alexandrite, ensuring its continued availability. Today, while the original Russian deposits are exhausted, significant sources have been found in Brazil, Sri Lanka, Tanzania, and Madagascar. Despite these new sources, fine-quality Alexandrite with a strong, vivid color change remains exceptionally rare, and the original Russian material is still considered the benchmark for quality.
The Science of Duality: Gemological Properties of Alexandrite
Alexandrite is a variety of the mineral chrysoberyl, renowned for its remarkable hardness and unique optical properties. Its chemical composition is beryllium aluminum oxide (BeAl₂O₄), with trace amounts of chromium (Cr³⁺) responsible for its signature color. The chromium impurities absorb light in the yellow part of the spectrum, but the specific way they do so in the chrysoberyl crystal lattice results in the dramatic color change.
The most famous characteristic of Alexandrite is its pleochroism, specifically its color-changing ability. In natural daylight or fluorescent light, which is rich in blue and green wavelengths, the stone appears in shades of green, blue-green, or teal. Under incandescent light or candlelight, which is rich in red and yellow wavelengths, the stone shifts to a red, purplish-red, or raspberry-red color. This effect is so pronounced that the stone is often described by the Russian proverb, "Sometimes it's like emerald, sometimes it's like ruby."
Alexandrite possesses a vitreous luster and is considered a durable gemstone, making it suitable for various types of jewelry. Its hardness on the Mohs scale is an impressive 8.5, placing it among the tougher of all gemstones, second only to corundum (ruby and sapphire) and diamond. This high hardness means it is resistant to scratching and can withstand daily wear with proper care.

| Crystal System | Orthorhombic | Amorphous | Monoclinic |
| Key Feature | Strong color change | Organic luster | Adularescence |
Symbolism, Lore, and Metaphysical Beliefs
Despite its relatively modern discovery compared to ancient gems like emerald or ruby, Alexandrite has accumulated a rich tapestry of symbolism and lore. Its defining characteristic—the shift from green to red—has imbued it with meanings of duality, balance, and transformation. It is seen as a stone that embodies the concept of "yin and yang," representing the ability to find light in darkness and to adapt to changing circumstances.
In Vedic and Zodiac astrology, Alexandrite is strongly associated with the sign of Gemini. The dual nature of the Gemini personality is perfectly mirrored in the gem's color-changing nature, making it a powerful talisman for those born under this sign. It is also linked in the Tarot to the Lovers card, symbolizing choices, relationships, and the harmony of opposites.
Metaphysical beliefs attribute several powers to Alexandrite. It is said to be a stone of intuition, capable of stimulating creativity and encouraging personal growth. For those born on June 14th, wearing Alexandrite is believed to enhance self-confidence and attract good fortune. Some traditions suggest that the stone's color change can act as a barometer for the wearer's energy levels, with the stone shifting to red when energy is low and to green when it is high. While these beliefs are rooted in folklore rather than science, they contribute to the gem's enduring mystique and popularity in the world of crystal healing.
Caring for Your Alexandrite Jewelry
Given its excellent hardness of 8.5 on the Mohs scale, Alexandrite is a robust gemstone suitable for everyday jewelry, including rings and bracelets. It is resistant to chipping and abrasion, making it a practical choice for active individuals. However, like all gemstones, it requires proper care to maintain its beauty.
To clean Alexandrite, the safest method is to use warm water, a mild soap, and a soft brush. Gently scrub the stone and its setting to remove any dirt or oils that may have accumulated. Rinse thoroughly with clean water and dry with a soft, lint-free cloth. Ultrasonic and steam cleaners are generally safe for Alexandrite, but it is always wise to ensure the stone is not fractured and that the jewelry setting is secure before using these methods. As with any fine jewelry, it is advisable to remove Alexandrite pieces before engaging in activities that could subject them to hard impacts or harsh chemicals.
Conclusion
Alexandrite is far more than just one of three birthstones for June; for those born on June 14th, it is a personal emblem of rarity, history, and duality. Its discovery in the Ural Mountains, its imperial Russian heritage, and its unparalleled color-changing ability set it apart in the gemological world. While pearls offer timeless elegance and moonstone provides ethereal glow, Alexandrite presents a dynamic and mysterious character. It is a gem that changes with its environment, a quality that makes it a fitting symbol for the complexities of life and a captivating treasure for any jewelry collection.
