June is a unique month in the world of gemstones, distinguished by the presence of three official birthstones: pearl, moonstone, and alexandrite. Among these, alexandrite stands out for its rarity, enchanting color-changing properties, and symbolic significance. Discovered relatively recently in the 19th century, alexandrite has since become a treasured gemstone, often associated with transformation, intuition, and good fortune. This article explores the geological, historical, and cultural significance of alexandrite, providing a comprehensive overview of its properties, symbolism, and care, as supported by the provided sources.
Introduction
Alexandrite is the rarest and most captivating of the June birthstones, prized for its ability to shift color depending on the light source. This phenomenon, known as the "alexandrite effect," makes it a unique and sought-after gem. It was officially recognized as a June birthstone in the 20th century and has since become a symbol of transformation and renewal. The stone's historical journey from discovery to modern recognition, along with its scientific composition and cultural significance, makes it a fascinating subject for gemologists and enthusiasts alike.
This article will delve into the geological formation of alexandrite, its historical background, symbolic meaning, and practical care tips. By examining the properties and lore surrounding this remarkable gem, we gain a deeper understanding of why alexandrite remains a cherished birthstone for those born in June.
History and Lore
Discovery and Early Recognition
Alexandrite was first discovered in the Ural Mountains of Russia in 1830. According to sources, its discovery coincided with the 18th birthday of Czar Alexander II, for whom the gem was named. The stone's color-changing ability was considered a marvel, and it quickly became a symbol of exclusivity and refinement. It was often set in elaborate jewelry pieces, including rings, brooches, and pendants, and was especially favored in royal and aristocratic circles.
The gem's rarity and beauty made it highly valued, but as the supply from the Ural Mountains dwindled, alexandrite became increasingly scarce, further elevating its status. This scarcity has contributed to its high value, making it one of the most sought-after gemstones in the world.
Modern Recognition
In the 20th century, alexandrite was officially recognized as a birthstone for June, joining the ranks of pearl and moonstone. This modern designation was largely influenced by the gemstone's unique properties and its growing popularity among collectors and jewelry enthusiasts. Unlike pearls and moonstone, which have been associated with June for centuries, alexandrite was introduced as a more recent addition to the birthstone lineup.
Today, alexandrite is considered one of the most valuable and sought-after gemstones in the world. Its rarity and beauty have made it a favorite among collectors, while its symbolic meaning of transformation and renewal continues to resonate with those who wear it.
Geological Formation and Sources
Chemical Composition and Formation
Alexandrite is a variety of the mineral chrysoberyl, which has the chemical formula BeAl₂O₄. What makes alexandrite unique is the presence of trace amounts of chromium and vanadium, which are responsible for its color-changing properties. These trace elements are responsible for the gem's ability to shift from green in daylight to red under incandescent light.
The formation of alexandrite occurs in metamorphic rocks, specifically in areas where beryllium-rich pegmatites and aluminum-rich schists intersect. These conditions are rare, contributing to the gem's scarcity. The presence of chromium, which is responsible for the red and green hues, is a key factor in the gem's color-changing effect.
Mining Locations
Historically, the primary source of alexandrite was the Ural Mountains in Russia, where it was first discovered. However, as natural deposits from this region became depleted, new sources were discovered in other parts of the world. Notable mining locations include:
- Brazil: A major source of alexandrite in the 20th century, Brazil has produced some of the finest color-changing specimens.
- India, Sri Lanka, and Madagascar: These countries have also contributed to the global supply of alexandrite, though the quality and intensity of the color change may vary.
Despite the discovery of new sources, alexandrite remains one of the rarest gemstones in the world, with high-quality specimens being particularly valuable.
Gemological Properties
Color and Appearance
Alexandrite is renowned for its ability to change color depending on the light source. In daylight or fluorescent lighting, it typically appears green due to the absorption of light by chromium ions. Under incandescent light, the stone appears red or purplish-red, as the light source emits more red wavelengths that are reflected by the gem. This unique phenomenon is known as the "alexandrite effect" and is a result of the gem's chemical composition and the way it interacts with different wavelengths of light.
The intensity of the color change can vary, and some specimens may also exhibit brownish or purplish tones. The most valuable alexandrites are those that display a dramatic and pure color shift from green to red.
Hardness and Durability
On the Mohs scale of mineral hardness, alexandrite ranks at 8.5, making it one of the harder gemstones. This high hardness means that it is relatively resistant to scratches and abrasions, making it suitable for everyday wear in jewelry. Additionally, alexandrite does not have cleavage, meaning it is unlikely to break or chip with accidental impacts. This durability contributes to its popularity in rings and other frequently worn pieces.
Other Physical Properties
- Luster: Vitreous (glassy)
- Refractive Index: 1.74–1.78
- Specific Gravity: 3.73–3.75
- Transparency: Transparent to translucent
These properties contribute to the gem's brilliance and fire, enhancing its visual appeal. The combination of its hardness, durability, and optical effects makes alexandrite a highly desirable gemstone.
Symbolism and Metaphysical Beliefs
Historical and Cultural Significance
Throughout history, alexandrite has been associated with transformation and change. Its color-shifting properties have been interpreted as a metaphor for personal growth and adaptability. In ancient times, it was believed that the stone could help individuals navigate life's transitions and embrace new opportunities.
The gemstone was also associated with good fortune and protection. In Russian folklore, alexandrite was believed to bring happiness and success, particularly to those born in June. It was often given as a gift to mark important life events, such as birthdays and anniversaries.
Modern Metaphysical Properties

Care and Cleaning
Cleaning Methods
Due to its high hardness and lack of cleavage, alexandrite is relatively easy to care for. It can be cleaned using warm soapy water and a soft cloth. Ultrasonic and steam cleaners are also safe for cleaning alexandrite, provided the mounting is secure and not loose.
However, it is important to note that the mounting should be checked before using an ultrasonic cleaner, as loose settings can damage the gemstone. Regular cleaning will help maintain the gem's brilliance and clarity.
