For those born on June 14, the birthstone is Alexandrite, a gemstone celebrated for its extraordinary color-changing ability and deep historical roots. While the month of June is uniquely associated with three official birthstones—pearl, moonstone, and Alexandrite—each date within the month often carries a specific association. For June 14, Alexandrite stands out as a modern alternative, embodying themes of transformation, balance, and regal heritage. This article delves into the geological properties, historical significance, cultural symbolism, and practical care of this remarkable gemstone, drawing exclusively from the provided sources to present an expert overview for gemstone enthusiasts, jewelry buyers, and students of gemology.
Alexandrite’s fame stems from its unique optical phenomenon, shifting from a verdant green in daylight to a rich red under incandescent light, a property that has captivated collectors and mystics alike. Its discovery in 1834 in the Ural Mountains of Russia and its subsequent naming after Tsar Alexander II cemented its status as an imperial gemstone, a symbol of Russian prestige and natural wonder. Beyond its visual allure, Alexandrite is deeply intertwined with the zodiac sign Gemini, representing duality and personal growth. This article will explore these facets in detail, providing a comprehensive guide to understanding one of June’s most enigmatic gems.
History and Lore
The history of Alexandrite is inextricably linked to a pivotal moment in Russian history. The gemstone was discovered in the Ural Mountains of Russia in 1834. Its naming was not arbitrary; it was chosen to honor Tsar Alexander II, who was set to ascend the Russian throne on the very day the stone was found. This serendipitous timing led to its immediate adoption as the Imperial gemstone of Russia, a status it retained for decades. The discovery location, the Ural Mountains, is significant, as this region has been a source of many precious gems, but none so uniquely tied to a specific historical event as Alexandrite.
The lore surrounding Alexandrite is as rich as its color-changing properties. It is often described as a "stone of transformation," a belief rooted in its ability to visibly alter its appearance based on the light source. This characteristic has made it a powerful symbol of change, balance, and renewal. In the context of June 14 births, Alexandrite is more than a mere adornment; it is a talisman for personal growth and adaptability. Its association with the zodiac sign Gemini, which spans from May 21 to June 20, further reinforces its symbolism of duality. As a June Gemini birthstone, Alexandrite perfectly represents emotional duality and spiritual alignment, embodying the multifaceted nature of those born under this sign.
While pearl is the oldest traditional June birthstone, symbolizing wisdom and serenity, and moonstone represents emotional balance and the divine feminine, Alexandrite is a more modern addition to the birthstone calendar. Its inclusion reflects a shift in preferences towards gems with unique and dramatic visual properties. The sources indicate that for those born on dates from June 16 to 30, Alexandrite or moonstone are often preferred, but its specific association with June 14 highlights its role as a personalized gem for those seeking a connection to transformation and imperial legacy.
Geological Formation and Sources
Alexandrite is a variety of chrysoberyl, a mineral composed of beryllium aluminum oxide (BeAl₂O₄). Its formation requires a specific and rare geological environment. The gemstone forms in pegmatites and metamorphic rocks, where the presence of beryllium and chromium is essential. Chromium is the trace element responsible for Alexandrite’s characteristic green color under daylight, while the color shift to red under incandescent light is due to the way the human eye perceives the gem’s absorption spectrum under different light sources.
The primary source of Alexandrite, as noted in the historical accounts, is the Ural Mountains of Russia. The Russian deposits, particularly those near Yekaterinburg, were the original source of the finest Alexandrite, known for its strong color change and vibrant hues. These stones are often considered the benchmark for quality, though they are exceptionally rare and command high prices in the market.
While the Russian deposits are historically significant, other locations have also yielded Alexandrite. However, the sources provided do not specify other mining locations, focusing instead on the Russian origin and its historical importance. For the purpose of this article, based solely on the provided materials, the Ural Mountains of Russia are the definitive and most significant source. The rarity of the gemstone, both historically and in the present day, is a direct result of the scarcity of suitable geological conditions and the depletion of the original Russian mines.
Gemological Properties
Alexandrite is renowned for its unique gemological properties, which set it apart from other green or red gemstones. The most defining characteristic is its color-change phenomenon, often described as "emeralds by day, rubies by night." Under natural daylight or fluorescent light, Alexandrite appears in shades of green, ranging from pale to vivid. Under incandescent or candlelight, it shifts to red, sometimes with purplish or brownish tones. This dramatic shift is a result of the gem's absorption of light in the yellow part of the spectrum, allowing the green and red wavelengths to dominate under different lighting conditions.
Chemical Composition: Alexandrite is a variety of chrysoberyl, with the chemical formula BeAl₂O₄. The presence of chromium ions (Cr³⁺) substituting for aluminum in the crystal lattice is responsible for its color and color change.
Hardness and Durability: On the Mohs scale of hardness, chrysoberyl (including Alexandrite) rates between 8.5 and 9, making it one of the hardest and most durable gemstones. This high hardness makes it suitable for all types of jewelry, including rings, that are subject to daily wear, as it is resistant to scratching and abrasion.
Crystal System: Alexandrite crystallizes in the orthorhombic system.
Refractive Index and Specific Gravity: While the specific refractive index and specific gravity are not detailed in the provided sources, these are standard gemological properties for chrysoberyl. The sources focus on the visual and symbolic properties rather than these technical measurements.
Clarity and Inclusions: The provided sources do not specify typical inclusions for Alexandrite. However, in general gemology, natural Alexandrite often contains inclusions such as silk (fine rutile needles) or fingerprint-like fluid inclusions. The quality of Alexandrite is often judged by the intensity of its color change, the clarity of the stone, and the absence of visible inclusions.
Color Spectrum: The color change is the primary determinant of value. The most prized Alexandrite exhibits a strong, vivid green to a vivid red shift. The presence of purplish or brownish tones can diminish the gem's value, though some stones with a subtle purplish hue are still highly sought after.

Symbolism and Metaphysical Beliefs
Alexandrite’s symbolism is deeply tied to its physical properties. Its ability to change color has made it a universal symbol of transformation, balance, and renewal. It is believed to bring about a sense of harmony and to help the wearer navigate change with grace and adaptability. This makes it a powerful gemstone for personal growth and for those undergoing significant life transitions.
In the context of astrology, Alexandrite is particularly significant for those born under the sign of Gemini. The duality of the stone—shifting between two distinct colors—mirrors the dual nature of the Gemini personality, which is often characterized by adaptability, curiosity, and a multifaceted perspective. As a June Gemini birthstone, Alexandrite is thought to enhance intuition, stimulate creativity, and encourage personal growth. Wearing Alexandrite is believed to boost intuition and encourage creative expression, making it a favored gem for artists, writers, and innovators.
Beyond its connection to Gemini, Alexandrite is also associated with the heart and crown chakras in metaphysical traditions, though this specific detail is not explicitly mentioned in the provided sources. The sources emphasize its role as a stone of transformation and balance, which aligns with broader spiritual beliefs about its ability to align the mind and emotions.
While the sources provided focus on the positive metaphysical attributes, it is important to note that these beliefs are part of cultural and spiritual traditions and are not scientifically verified. In the context of gemology, these symbolic meanings add a layer of cultural significance to the stone’s physical beauty.
Care and Cleaning
Given its exceptional hardness (8.5 to 9 on the Mohs scale), Alexandrite is a durable gemstone that can withstand daily wear with proper care. Its resistance to scratching and abrasion makes it suitable for rings, earrings, pendants, and bracelets. However, like all gemstones, it requires proper maintenance to preserve its beauty and structural integrity.
Cleaning: Alexandrite can be safely cleaned using warm water, a mild dish soap, and a soft brush. Ultrasonic cleaners and steam cleaners are generally safe for Alexandrite due to its hardness and lack of cleavage planes. However, it is always advisable to avoid sudden temperature changes, which could potentially damage the stone or its setting, especially if the stone has inclusions.
Storage: When not in use, Alexandrite jewelry should be stored separately from other jewelry to prevent scratching. A soft cloth pouch or a compartmentalized jewelry box is ideal.
Considerations: While Alexandrite is durable, it is important to protect it from hard blows or impacts that could cause chipping or cracking, though this is rare due to its toughness. Additionally, as with all colored gemstones, prolonged exposure to harsh chemicals (e.g., household cleaners, chlorine in swimming pools) should be avoided to prevent potential damage to the stone or its setting.
The care instructions for Alexandrite are straightforward, making it a practical choice for everyday jewelry. Its durability ensures that, with proper care, an Alexandrite piece can be a lasting heirloom.
