History and Lore
The history of the June birthstones is as varied and colorful as the stones themselves. While pearls are the oldest of the three and have been revered for thousands of years, alexandrite is a relatively recent discovery, while moonstone has been admired for its mystical qualities in various cultures.
Pearl: The Classic June Birthstone
Pearls are often considered the most traditional of the three June birthstones. Unlike most gemstones, which are formed through geological processes, pearls are organic gemstones formed within the soft tissue of a living organism—typically a mollusk such as an oyster or mussel. This unique origin gives pearls a distinct softness and iridescence that has been prized since ancient times.
Historically, pearls have been associated with purity, wisdom, and elegance. In ancient Rome, they were considered symbols of wealth and power, often worn by emperors and senators. In China, pearls were believed to promote longevity and were used in traditional medicine. The orient, or the soft inner glow of a pearl, has long been associated with a sense of calm and serenity.
The luminous quality of pearls has made them a popular choice for formal wear and special occasions. Their color palette is extensive, ranging from classic white and cream to rare black, gold, and even pink or violet. This versatility has allowed pearls to remain relevant across centuries, evolving from royal treasures to everyday jewelry staples.
Alexandrite: The Modern Marvel
Alexandrite is the youngest of the three June birthstones, discovered in the Ural Mountains of Russia in 1834. Named in honor of Czar Alexander II on the occasion of his 16th birthday, alexandrite quickly became a symbol of Russian pride and prestige. Its most remarkable feature is its color-changing property, shifting from green in daylight to red under incandescent light. This phenomenon is due to a combination of pleochroism (the ability to display different colors when viewed from different angles) and the influence of different light sources.
The discovery of alexandrite was attributed to several individuals, including Nils Gustaf Nordenskiöld, Vasilevich Kokovin, and Count L.A. Perovskii, though the exact origin of the discovery remains a matter of historical debate. Regardless of its discoverer, alexandrite's chameleon-like behavior made it an instant favorite among gem connoisseurs and nobility alike.
Alexandrite was also believed to carry metaphysical properties, such as protection from danger. Some cultures interpreted its color change as a warning sign, while others saw it as a symbol of love’s many shades. Its rarity and beauty have only increased in value over time, making it one of the most sought-after and expensive gemstones in the world.
Moonstone: The Enchanted Glow
Moonstone, the third June birthstone, has a mystical and ethereal quality that has captivated people for centuries. Known for its iridescent sheen, or schiller, moonstone appears to shimmer with a soft, silvery light—reminiscent of moonlight on water. This effect is caused by the interference of light within the stone, a result of its layered structure.
Moonstone has been associated with intuition, emotional balance, and spiritual insight. In ancient India, it was considered a sacred stone, used in jewelry and talismans to bring good fortune. In the Victorian era, moonstone was a popular gemstone in mourning jewelry, symbolizing the changing emotions of grief and remembrance.
The color of moonstone varies, with blue sheen being the most prized. Other variations include white, beige, and even rainbow-colored moonstone, which displays multiple colors under different light conditions. This diversity has allowed moonstone to be used in a wide range of jewelry styles, from delicate pendants to bold statement rings.
Geological Formation and Sources
Understanding the geological formation and sources of each June birthstone provides insight into their rarity and value. Each of these gemstones forms under unique conditions and is found in specific regions around the world.
Alexandrite: A Rare and Precious Chrysoberyl
Alexandrite is a rare variety of chrysoberyl, a mineral composed of beryllium aluminum oxide (BeAl₂O₄). The color change in alexandrite is due to the presence of chromium and vanadium impurities, which affect the way the stone absorbs and reflects light.
Originally discovered in the Ural Mountains of Russia, alexandrite was the only known source for nearly a century. By the 1890s, Russian deposits were nearly depleted, and the stone became extremely rare. In 1987, new sources were discovered in Brazil, followed by Sri Lanka and Zimbabwe. These new deposits have helped meet the demand for alexandrite, though high-quality stones remain exceptionally scarce.
Alexandrite is typically found in granite pegmatites, a type of igneous rock formed by the slow cooling of magma. The conditions required for alexandrite formation are very specific, which contributes to its limited availability.
Pearl: The Organic Gemstone
Unlike alexandrite, pearls are not formed through geological processes but are organic gemstones created within the soft tissue of mollusks. The process begins when an irritant, such as a grain of sand, enters the shell of a mollusk. In response, the mollusk secretes nacre, a substance composed of calcium carbonate, conchiolin, and water, to coat the irritant. Over time, layers of nacre build up, forming a pearl.
Pearls can be naturally occurring or cultivated through pearl farming. Cultured pearls are created when a small bead or piece of mantle tissue is inserted into the mollusk to stimulate pearl formation. This process allows for greater control over the size, shape, and color of the resulting pearl.
Pearls are found in various parts of the world, including Japan, China, Australia, Indonesia, and the Persian Gulf. Different types of pearls, such as Akoya, Tahitian, and South Sea pearls, are distinguished by their origin, size, and color. Akoya pearls, for example, are typically small and white, while Tahitian pearls are known for their black and iridescent hues.
Moonstone: A Feldspar with a Shimmer
Moonstone is a type of feldspar mineral, specifically a potassium aluminum silicate (KAlSi₃O₈). Its iridescent sheen is caused by the refraction of light as it passes through layers of different feldspar components. This effect is most prominent in blue moonstone, where the interference of light creates a soft, silvery glow.
Moonstone is typically found in pegmatite and metamorphic rock deposits, particularly in regions such as India, Sri Lanka, Myanmar, and the United States. The Burma (Myanmar) moonstone is especially prized for its vivid blue sheen, while Indian moonstone is known for its white or beige hues.
The layered structure of moonstone makes it relatively soft and fragile compared to other gemstones. It has a Mohs hardness of 6 to 6.5, which means it requires careful handling and is best suited for jewelry that is not subject to constant wear.
