June holds a unique distinction in the world of birthstones. While most months are assigned a single gem, June celebrates a trio of stones: pearl, moonstone, and alexandrite. This remarkable variety offers individuals born in this month a diverse palette of colors, textures, and symbolic meanings, ranging from the classic elegance of pearls to the ethereal glow of moonstone and the transformative magic of alexandrite. The existence of three official birthstones for June is not a modern marketing invention but the result of a historical evolution in birthstone charts, reflecting changes in gemstone availability, cultural preferences, and the desire to provide more choice for consumers. This article delves into the distinct characteristics, rich histories, geological origins, and symbolic significance of each of June's three birthstones, providing a comprehensive guide for gemstone enthusiasts, jewelry buyers, and students of gemology.
The journey of June's birthstones begins with the pearl, the oldest and most traditional option. For centuries, the pearl has been revered for its natural beauty and its symbolism of purity, wisdom, and serenity. Formed within living mollusks, the pearl is unique among gemstones as an organic gem, a product of the sea rather than the Earth's crust. Its soft luster and classic white hues have made it a timeless choice for jewelry, particularly for brides and those seeking a symbol of innocence and emotional healing. The pearl's enduring popularity established its place as June's original birthstone, a position it holds in many traditional and modern lists.
As the 20th century progressed, the birthstone list evolved to accommodate other gems that had gained cultural traction. Moonstone, a member of the feldspar mineral family, was added to June's roster, particularly in more modern lists popular in Europe. Known for its captivating adularescence—a shimmering, billowy light that seems to float across the stone's surface—moonstone is associated with intuition, emotional balance, and the divine feminine. Its celestial glow, often in shades of white with flashes of blue, connects it to lunar energy and makes it a favorite for those seeking creativity and serenity.
The most recent addition to June's birthstone family is alexandrite, a rare and remarkable gemstone that joined the list in the 1950s. Alexandrite is famed for its extraordinary color-changing ability, shifting from a green or bluish-green in daylight or fluorescent light to a reddish-purple or brownish-purple under incandescent light. This duality made it especially significant for those born under the sign of Gemini, embodying the concept of transformation and balance. Its rarity and unique optical phenomenon have made it a prized gem, representing joy, prosperity, and personal growth.
The coexistence of these three stones offers a rich tapestry of choices for June-born individuals. The pearl provides classic elegance, moonstone offers mystical allure, and alexandrite delivers a rare and dynamic spectacle. Understanding the distinct properties and stories of each gem allows for a deeper appreciation of June's gemological diversity and the personal significance each stone can hold.
History and Lore
The historical significance of June's birthstones is as varied as the stones themselves, with each gem carrying a legacy shaped by centuries of cultural use and belief. The pearl stands as the most ancient of the trio, with a history that predates recorded gemology. As the original birthstone for June, the pearl has been a symbol of purity, wisdom, and serenity across numerous civilizations. Its formation within living mollusks has long been seen as a miracle of nature, linking it to life, emotion, and the subconscious. In many cultures, pearls were believed to bring inner peace, calmness, and clarity to the wearer. They were often associated with the moon due to their lustrous, reflective quality and were thought to embody its calming and nurturing energy. The pearl's historical role as a birthstone is deeply rooted in its organic origin and its timeless aesthetic, making it a foundational element in the lore of June gemstones.
Moonstone's history is steeped in mysticism and lunar symbolism. While it was formally added to June's birthstone list in more modern times, its lore stretches back to ancient civilizations. The stone's name itself derives from its visual connection to the moon, with its shimmering adularescence reminiscent of moonlight on water. Historically, moonstone has been revered as a stone of new beginnings, intuition, and emotional balance. It is deeply tied to the concept of the divine feminine, nurturing creativity and spiritual insight. In various cultures, it was believed to be formed from solidified moonlight, granting it the power to connect the wearer to lunar cycles and enhance psychic abilities. Its inclusion in June's birthstone roster reflects a broader 20th-century trend to incorporate stones with strong metaphysical associations and aesthetic appeal, complementing the traditional pearl.
Alexandrite is the youngest of the three in terms of its birthstone status, but it boasts a dramatic and royal history. Discovered in the Ural Mountains of Russia in the 1830s, it was named after the future Tsar Alexander II. The gem's most famous property—its color change from green to red—was said to mirror the military colors of Imperial Russia, leading to its immediate favor in the Russian court. This historical origin story is well-documented and adds a layer of regal significance to the stone. Alexandrite was officially added to the modern birthstone list in the 1950s, a decision that acknowledged its unique characteristics and growing appeal. Its lore is centered on duality, transformation, and good fortune. The stone's ability to change color under different light sources is seen as a metaphor for life's transitions and the balance between different aspects of one's personality, making it particularly resonant for the Gemini sign.
The evolution of June's birthstone list from a single stone (pearl) to a trio (pearl, moonstone, alexandrite) reflects a dynamic interplay between tradition and modernity. While the pearl remains the cornerstone, the additions of moonstone and alexandrite expanded the emotional and aesthetic range available to June-born individuals. This historical progression was driven by organizations like the American National Retail Jewelers Association (now Jewelers of America), which standardized birthstone charts in the early 20th century and later updated them to include stones that had gained cultural prominence. The result is a unique month that offers a spectrum of choices, each with its own rich historical narrative.
Geological Formation and Sources
Understanding the geological origins of June's birthstones reveals why they are so fundamentally different from one another. Pearl, moonstone, and alexandrite are formed through entirely distinct processes, which directly influences their appearance, availability, and sourcing.
Pearl: The Organic Gem Pearls are unique among gemstones as they are organic gems, formed within living mollusks such as oysters and mussels. The process begins when an irritant, such as a grain of sand or a parasite, enters the mollusk's soft tissue. In response, the mollusk secretes layers of nacre (a composite material made of aragonite and conchiolin) around the irritant to protect itself. Over several years, these layers build up to form a pearl. Natural pearls are exceptionally rare, as this process occurs without human intervention. Historically, the primary sources of natural pearls were the Persian Gulf, the Red Sea, and the waters around Sri Lanka and India. Due to overharvesting and pollution, natural pearls are now extremely scarce and valuable.
The vast majority of pearls on the market today are cultured pearls, a process pioneered in the early 20th century. In pearl farming, humans intentionally introduce an irritant (often a bead of mother-of-pearl) into the mollusk to stimulate nacre production. Major sources of cultured pearls include Japan (for Akoya pearls), China (for freshwater pearls), and French Polynesia (for Tahitian pearls). The organic nature of pearls means they are not mined from the earth but harvested from the sea or freshwater farms, making their sourcing a unique branch of gemology.
Moonstone: A Feldspar Family Member Moonstone is a variety of the mineral feldspar, specifically orthoclase or albite. It forms in igneous and metamorphic rocks, often in large crystals. The characteristic adularescence of moonstone is caused by the alternating layers of orthoclase and albite, which scatter light in a way that creates the shimmering, billowy effect. This optical phenomenon is known as "labradorescence" in other feldspars but is specifically called "adularescence" in moonstone.
Moonstone is mined in various locations around the world. Historically, the finest quality moonstone came from Sri Lanka. Other significant sources include India (particularly for moonstones with a strong blue sheen), Brazil, Madagascar, and the United States (in states like Virginia and North Carolina). The quality of moonstone is often judged by the intensity and visibility of its adularescence, with the most prized specimens displaying a clear, blue sheen over a colorless or white body.
Alexandrite: A Rare Chrysoberyl Alexandrite is a variety of the mineral chrysoberyl (BeAl₂O₄) and is one of the rarest and most valuable gemstones in the world. Its formation requires a very specific geological environment. Chrysoberyl crystals grow in pegmatites and metamorphic rocks, but for alexandrite to form, the presence of chromium (which causes the color change) must be precisely balanced. This rare combination of elements and conditions makes natural alexandrite exceptionally scarce.
The original and most famous source of alexandrite is the Ural Mountains in Russia, where it was discovered in the 1830s. These Russian deposits, primarily in the region near the Tokovaya River, produced the finest alexandrite with a dramatic color change from green to red. However, these mines are now largely depleted. In the late 20th century, significant deposits of alexandrite were found in Brazil, particularly in the states of Minas Gerais and Bahia. Brazilian alexandrite often shows a color change from bluish-green to purplish-red. Other, smaller sources have been found in Sri Lanka, India, and East Africa (e.g., Tanzania), though the material from these locations is often less valuable than the Russian or Brazilian gems.
The rarity of natural alexandrite has led to the development of synthetic alexandrite (created in laboratories) and simulant materials (like color-change sapphires or synthetic spinel) to meet market demand. The geographical and geological rarity of natural alexandrite contributes significantly to its high market value and its status as a prized modern birthstone.
Gemological Properties
The gemological properties of pearl, moonstone, and alexandrite are as distinct as their origins, influencing their durability, care requirements, and suitability for jewelry. The following table provides a comparative overview of their key properties, based on established gemological standards.

|---|---|---|---|
| Mineral Species | Organic (Nacre) | Feldspar (Orthoclase/Albite) | Chrysoberyl |
| Chemical Formula | CaCO₃ (Aragonite) & Organic Matrix | KAlSi₃O₈ (Orthoclase) | BeAl₂O₄ |
| Crystal System | Amorphous (Nacre layers) | Monoclinic | Orthorhombic |
| Hardness (Mohs Scale) | 2.5 - 4.5 | 6 - 6.5 | 8.5 |
| Refractive Index | 1.49 - 1.68 (Variable) | 1.518 - 1.526 | 1.746 - 1.755 |
| Specific Gravity | 2.72 - 2.78 | 2.56 - 2.59 | 3.68 - 3.78 |
| Luster | Subvitreous to Waxy | Vitreous to Pearly | Vitreous |
| Optical Phenomena | Orient (Iridescence) | Adularescence | Strong Color Change |
| Durability | Low (Soft, Porous) | Fair (Prone to abrasion) | Excellent (Very Hard) |
| Common Treatments | Bleaching, Dyeing, Coating | Heat Treatment (often), Oiling | Heat Treatment (to enhance color) |
Pearl: As an organic gem, pearls are relatively soft and have a unique structure. Their hardness on the Mohs scale ranges from 2.5 to 4.5, making them susceptible to scratches and abrasions. Their specific gravity is moderate, and their refractive index is variable due to their layered nacre structure. The most prized optical property of pearls is "orient," a subtle iridescence that plays over the surface. Pearls are porous, which makes them sensitive to chemicals, perfumes, and acids. They are often treated to improve color and luster, with common treatments including bleaching, dyeing, and coating with a thin layer of nacre.
Moonstone: As a member of the feldspar group, moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it moderately durable but not suitable for rings worn daily without protection. It has a vitreous to pearly luster and a specific gravity of 2.56 to 2.59. Its defining gemological property is adularescence, the billowy, floating light caused by light scattering between its microscopic layers. Moonstone is often heat-treated to improve its color and clarity, though this is generally stable. It has good toughness but can be prone to cleavage if struck at the right angle.
Alexandrite: Alexandrite is a member of the chrysoberyl family and is one of the hardest and most durable gemstones. With a hardness of 8.5 on the Mohs scale, it is highly resistant to scratching and is suitable for all types of jewelry, including rings. Its specific gravity is significantly higher than the other two stones, and it has a high refractive index, contributing to its brilliance. The most critical gemological property of alexandrite is its strong color change, which is caused by the presence of chromium and the way the stone absorbs light. The quality of the color change (the degree of contrast and the specific hues) is a primary factor in determining its value. Alexandrite is often heat-treated to enhance or alter its color, a treatment that is generally accepted in the gem trade.
These gemological differences directly impact care and cleaning. Pearls require gentle handling and should be cleaned with a soft, damp cloth. Moonstone should be protected from hard blows and cleaned with mild soap and water. Alexandrite, due to its hardness, can be cleaned with standard jewelry cleaning methods, including ultrasonic cleaners, though it should be protected from extreme heat.

Care and Cleaning
The proper care of gemstone jewelry is essential to preserve its beauty and longevity. The distinct physical properties of pearl, moonstone, and alexandrite necessitate different care routines.
Caring for Pearls Due to their organic nature and relative softness, pearls require the most delicate handling. * Cleaning: Pearls should be wiped with a soft, damp cloth after each wear to remove body oils and cosmetics. Avoid ultrasonic cleaners, steam cleaners, and harsh chemicals, including ammonia-based cleaners. For a deeper clean, use a mild soap solution and a soft brush, then rinse and pat dry immediately. * Storage: Store pearls separately from other jewelry to prevent scratches. It is best to keep them in a soft pouch or lined jewelry box. Pearls benefit from a slightly humid environment, so avoid storing them in a dry, airtight container for long periods, as this can cause the nacre to crack. * Wearing: Pearls should be the last item you put on (after cosmetics, perfume, and hairspray) and the first item you take off. Avoid exposing pearls to excessive heat, sunlight, or acids.
Caring for Moonstone Moonstone is moderately durable but can be prone to scratches and cleavage. * Cleaning: Use warm water, mild soap, and a soft brush to clean moonstone. Avoid ultrasonic cleaners and steam cleaners, as the vibrations and heat can damage the stone. Dry thoroughly with a soft cloth. * Storage: Store moonstone in a fabric-lined box or a soft pouch, away from harder gemstones like diamonds or sapphires that could scratch it. * Wearing: While moonstone can be set in rings, it is advisable to choose protective settings (like bezels) for pieces that will be worn daily. Avoid exposing it to hard blows or extreme temperature changes.
Caring for Alexandrite Alexandrite is exceptionally hard and durable, making it the easiest of the three to care for. * Cleaning: Alexandrite can be safely cleaned with warm water, mild detergent, and a soft brush. It is also safe for ultrasonic cleaning, though caution should be exercised if the stone has fractures or inclusions. Steam cleaning is generally acceptable but should be avoided if the stone has been treated with heat-sensitive coatings. * Storage: Due to its hardness, alexandrite can be stored with other jewelry without risk of scratching, but it is still best practice to keep pieces separate to prevent damage to settings. * Wearing: Alexandrite is suitable for all types of jewelry, including rings and bracelets, and can withstand daily wear. Its high hardness and toughness make it a practical choice for active lifestyles.
