June is unique among the months, offering not one, but three distinct birthstones: pearl, moonstone, and alexandrite. This trio represents a remarkable spectrum of gemological diversity, from the organic luster of pearls to the ethereal shimmer of moonstone and the dramatic color-shifting magic of alexandrite. Each stone carries its own rich history, symbolic meaning, and set of physical properties, providing those born in June with a wide array of choices that reflect personal style and character. The 1912 standardization by the National Association of Jewelers (now the Jewelers of America) originally named pearl as the primary June birthstone, but modern additions have expanded the options to include moonstone and alexandrite, acknowledging the varied traits of individuals born during this month of warmth and growth.
This article explores the captivating world of June’s birthstones, delving into their colors, historical significance, geological origins, gemological properties, and care. It examines why these three gems—pearl, moonstone, and alexandrite—have been chosen to represent June and how their distinct energies and visual appeal continue to enchant gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore: From Ancient Pearls to Imperial Alexandrite
The history of June’s birthstones spans millennia and cultures, with each gem holding a distinct place in human tradition. The pearl, the oldest of the three, has been revered for centuries as a symbol of purity, wisdom, and serenity. Historically, pearls were associated with faithfulness and purity, often worn by royalty to symbolize the purity of their bloodline. Their connection to the moon and the water element has made them a calming presence, believed to offer soothing energies and emotional balance. In ancient times, pearls were among the most prized gems, their natural beauty requiring no faceting or cutting to shine.
Moonstone’s lore is deeply rooted in Eastern cultures, particularly in India and Tibet. It has long been considered a sacred stone, linked to the divine feminine, intuition, and emotional clarity. In Hindi culture, moonstones are believed to bring good fortune and blessings. Their milky white appearance with a shimmering adularescent sheen has made them a symbol of mystery and new beginnings, aligning with the gentle progression from spring to summer. For centuries, moonstone has been featured in jewelry, valued for its soft glow that seems to emanate from within.
Alexandrite, the most recent addition to June’s birthstone family, has a more specific and dramatic history. Discovered in the Ural Mountains of Russia in the 1830s, this gem was named after the future Tsar Alexander II. Its unique color-changing property—green in daylight and red in incandescent light—mirrored the imperial Russian military colors, making it a national treasure. Alexandrite quickly became a symbol of duality and balance, inspiring emotional maturity and adaptability. While it is a modern birthstone for June, its rarity and mystical properties have secured its place as a gem of great significance.
The journey to establishing these three stones as June’s birthstones reflects a broader trend in gemology and jewelry. While pearl was the traditional choice, the addition of moonstone and alexandrite by the Jewelers of America in the 20th century acknowledged the need for options that cater to diverse tastes and personalities. Earlier variations, such as 19th-century poems that assigned agate to June, were eventually superseded by the more universally appreciated pearl, moonstone, and alexandrite. Today, all three are officially recognized, each offering a unique connection to the qualities of those born in June.
Geological Formation and Sources
Understanding the origins of these gems reveals fascinating contrasts between organic and mineral formations. Pearls are unique among gemstones as organic gems, formed within living mollusks such as oysters and mussels. When an irritant, like a grain of sand, enters the mollusk’s shell, it secretes layers of nacre—a combination of calcium carbonate and conchiolin—around the irritant, eventually forming a pearl. Natural pearls are exceptionally rare, and most pearls on the market today are cultured, where humans intentionally introduce an irritant to stimulate pearl formation. Major sources for cultured pearls include Japan, China, Australia, and the South Pacific islands, each producing pearls with distinct colors and qualities.
Moonstone is a variety of the mineral feldspar, specifically orthoclase or albite. Its characteristic adularescence—the shimmering light that seems to move across the stone—is caused by the interaction of light with microscopic layers of alternating feldspar. Moonstone is typically found in igneous and metamorphic rocks, with notable sources including Sri Lanka, India, Myanmar, and Madagascar. The finest moonstones display a clear, bluish sheen on a nearly colorless body.
Alexandrite is a variety of chrysoberyl, a beryllium aluminum oxide mineral. Its color-changing ability is due to the presence of trace amounts of chromium in its crystal structure. Alexandrite forms under specific geological conditions, often in pegmatites or alluvial deposits. Historically, the finest alexandrite came from the Ural Mountains of Russia, but today, significant deposits are found in Brazil, Sri Lanka, and East Africa. The Russian stones are prized for their vivid green-to-red change, while Brazilian alexandrite may exhibit a different range of colors.
The following table summarizes the primary sources for each June birthstone based on the provided information:
| Gemstone | Primary Sources | Formation Type |
|---|---|---|
| Pearl | Japan, China, Australia, South Pacific | Organic (nacre from mollusks) |
| Moonstone | Sri Lanka, India, Myanmar, Madagascar | Mineral (feldspar) |
| Alexandrite | Russia (historical), Brazil, Sri Lanka, East Africa | Mineral (chrysoberyl) |
Gemological Properties: Color, Hardness, and Structure
The gemological properties of June’s birthstones vary widely, reflecting their different origins and compositions. Color is a defining characteristic for each, influencing both their aesthetic appeal and symbolic meanings.
Pearls are renowned for their soft, iridescent hues. The finest pearls exhibit a creamy white color with a hint of rainbow-like sheen, known as “orient.” However, pearls come in a wide range of colors, including pink, blue, grey, black, gold, green, and purple. Cultured freshwater pearls can be dyed to achieve vibrant colors like purple, black, brown, pink, yellow, green, or blue. Black pearls, often from Tahiti, are not truly black but display dark shades of purple, blue, green, or silver. Pearls have a Mohs hardness of 2.5 to 4.5, making them relatively soft and prone to scratching. They lack cleavage and have a conchoidal fracture, with a specific gravity of 2.72 to 2.78. Their luster is a key quality indicator, ranging from excellent to poor.
Moonstone is characterized by its milky white to colorless body with a distinctive adularescent sheen. The most prized moonstones show a clear, bluish light that moves across the stone’s surface. Variations may include shades of grey, peach, or rainbow hues. Moonstone has a Mohs hardness of 6 to 6.5, making it more durable than pearl but still requiring careful handling. It belongs to the monoclinic crystal system and has a specific gravity of 2.56 to 2.59. Its transparency ranges from translucent to opaque, with the best specimens being nearly transparent.
Alexandrite is celebrated for its dramatic color change, known as the “alexandrite effect.” In daylight or fluorescent light, it appears green, while under incandescent light, it shifts to reddish-purple, sometimes with purplish or brownish tones. This property is due to the gem’s unique absorption spectrum. Alexandrite has a Mohs hardness of 8.5, making it exceptionally durable and suitable for everyday jewelry. It is a member of the chrysoberyl family, with a chemical composition of BeAl₂O₄ and a specific gravity of 3.50 to 3.54. Its crystal system is orthorhombic, and it typically exhibits a vitreous luster.

Pearls are also symbols of new beginnings and fresh starts, making them ideal for personal growth and renewal. In metaphysical beliefs, pearls are believed to alleviate anxiety, instill calmness, and promote emotional balance. They are often recommended for those seeking clarity and decision-making abilities.
Moonstone is deeply connected to intuition, mystery, and emotional balance. Its association with the moon and the water element makes it a stone of calm and serenity. In Tibetan culture, moonstone is revered for its ability to enhance intuition and emotional clarity. It is believed to align with the gentle progression of life, encouraging inner growth and new beginnings. Moonstone’s soothing energies are thought to help individuals tune into calmer frequencies, improving their overall quality of life.
Alexandrite symbolizes duality, adaptability, and joy. Its color-changing property represents the balance between mind and emotions, promoting emotional maturity and adaptability. Alexandrite is often seen as a stone of good fortune and joy, mirroring the dynamic nature of those born in June. In metaphysical traditions, it is believed to inspire creativity and help individuals navigate transitions with grace. The gem’s rarity and mystical properties make it a powerful talisman for personal transformation.
Together, these three stones embody the creative, nurturing, and spiritually curious energies of June. Whether one is drawn to the calming influence of pearl, the intuitive glow of moonstone, or the adaptable magic of alexandrite, each gem offers a unique pathway to emotional and spiritual well-being.
Care and Cleaning: Preserving June’s Gems
Proper care is essential to maintain the beauty and longevity of each June birthstone, given their distinct physical properties. Pearls, with their low hardness and organic composition, require the most attention. They should be stored separately from other jewelry to avoid scratches and kept away from chemicals, including perfumes, hairsprays, and cosmetics, which can damage their nacre. To clean pearls, use a soft, damp cloth and mild soap, then dry gently with a soft cloth. Avoid ultrasonic cleaners and excessive water exposure, as pearls are porous and can absorb liquids, leading to discoloration or damage.
Moonstone, with a hardness of 6 to 6.5, is more durable than pearl but still demands careful handling. It should be protected from sharp blows and extreme temperature changes, which can cause cracking. Cleaning moonstone is straightforward: use warm water, a mild soap, and a soft brush to remove dirt. Ultrasonic cleaners are generally safe for moonstone, but steam cleaning should be avoided due to the risk of thermal shock. Store moonstone jewelry in a soft cloth or padded box to prevent scratches.
Alexandrite, with a hardness of 8.5, is the most durable of the three and can withstand everyday wear. However, it is still advisable to protect it from hard impacts and extreme temperatures. Cleaning alexandrite is simple: use warm soapy water and a soft brush, or an ultrasonic cleaner for thorough cleaning. Avoid harsh chemicals and sudden temperature changes to preserve its color-changing properties. Due to its rarity and value, it is wise to have alexandrite jewelry inspected regularly by a professional jeweler.
In summary, while pearl requires gentle, cautious care, moonstone and alexandrite offer greater durability but still benefit from mindful handling. By following these care guidelines, owners can ensure their June birthstones remain vibrant and beautiful for generations.
