June is unique in the gemological calendar, offering not one, but three distinct birthstones: Pearl, Alexandrite, and Moonstone. This trio provides individuals born in the sixth month of the year with an exceptional variety of choices, ranging from the classic organic elegance of pearls to the dramatic color-changing properties of alexandrite and the ethereal adularescence of moonstone. The existence of multiple stones for June allows for a wide spectrum of colors, price points, and personal expressions.
The modern birthstone lists, which evolved from historical and biblical traditions, have expanded to include these options, giving June birthdays a rare flexibility. While Pearl is the oldest and most traditional of the three, Alexandrite and Moonstone have been officially recognized in various iterations of the birthstone list, particularly in modern updates by organizations like the National Association of Jewelers. Understanding the distinct origins, properties, and lore of each stone is essential for gemstone enthusiasts and collectors alike.
The Historical Evolution of June's Gems
The assignment of birthstones to specific months has a long and complex history, tracing back to the breastplate of Aaron described in the Book of Exodus, which featured twelve stones representing the twelve tribes of Israel. Over time, these stones were associated with the twelve signs of the zodiac and eventually the twelve months of the year. The modern birthstone list, as we largely know it today, was standardized in 1912 by the American National Association of Jewelers (now Jewelers of America). However, this list was not static; it has been updated over the years to reflect availability, popularity, and new discoveries.
For June, the evolution is particularly interesting. The 1912 list designated Pearl as the modern birthstone, with Moonstone serving as the traditional alternative. This remained the standard for decades. However, the allure of Alexandrite, a gem discovered in the 19th century, eventually led to its inclusion. In 1952, the Jewelers of America added Alexandrite to the list of stones for June. Later, in 2002 and 2013, the National Association of Jewelers (UK) added Moonstone to the modern list, solidifying the trio we recognize today.
This progression highlights a shift in the perception of birthstones from strictly historical artifacts to a more inclusive selection that values rarity, beauty, and personal resonance. While Pearl remains the most traditional and widely recognized, Alexandrite offers a unique narrative of imperial Russian history, and Moonstone provides a connection to ancient mysticism and Art Nouveau jewelry. The availability of these three stones ensures that a June-born individual can select a gem that aligns with their budget, aesthetic preference, and personal connection to gem lore.
Pearl: The Organic Gem of Wisdom and Serenity
Pearl stands as the oldest and most traditional of the June birthstones. Unlike all other gemstones, which are minerals mined from the earth, pearls are organic gems created by living organisms. They form inside the tissue of a living saltwater or freshwater mollusk, such as an oyster or a mussel. The process begins when an irritant, such as a grain of sand or a parasite, invades the mollusk's shell. In defense, the mollusk secretes a substance called nacre (calcium carbonate) in concentric layers around the irritant. Over time, these layers build up to form a lustrous pearl.
The origin of pearls fascinated ancients across the globe. Legends from the Middle East suggested pearls were teardrops fallen from heaven, while the Chinese believed they originated from the brain of a dragon. Christopher Columbus and his contemporaries theorized that pearls formed from dewdrops trapped in mollusk shells. These myths underscore the pearl's mystical status throughout history.
Pearls have been treasured for millennia, valued for their subtle luster and rarity before the advent of cultured pearls. Historically, natural pearls were so rare that only royalty and the extremely wealthy could afford them. The discovery of vast oyster beds in the New World during the 15th and 16th centuries made pearls more accessible to European aristocracy, but over-harvesting eventually decimated these natural sources.
Today, the vast majority of pearls on the market are cultured pearls, which are a product of human intervention where a technician intentionally introduces an irritant into the mollusk. While the formation process is the same, cultured pearls allow for a consistent supply of these gems. Freshwater pearls, which can be cultivated in lakes and rivers, are generally more abundant and affordable than their saltwater counterparts, such as Akoya, Tahitian, or South Sea pearls.
Symbolism and Lore of the Pearl
Throughout history, pearls have been associated with purity, innocence, and wisdom. In the Middle East, it was believed that pearls preserved the wearer's integrity. In many cultures, pearls are traditional wedding gifts, symbolizing tears and the purity of love. Metaphysically, pearls are often associated with calming energies, bringing peace and serenity to the wearer. They are said to enhance personal integrity and help to clear one's mind for better focus.
Gemological Properties of Pearl
Pearls are evaluated based on several factors, including luster, surface quality, shape, size, and color. The luster—the sharpness and intensity of the light reflected from the surface—is the most important quality determining a pearl's beauty.
- Composition: Calcium carbonate (CaCO3) in the form of aragonite or calcite, with a small amount of conchiolin.
- Hardness: Pearls are relatively soft compared to mineral gemstones, with a Mohs hardness of 2.5 to 4.5. This makes them susceptible to scratches and damage from acids, including vinegar and perspiration.
- Color: Pearls occur in a wide range of colors, from classic white and cream to black, blue, green, and purple. Natural color depends on the type of mollusk and the water conditions.
- Luster: The reflection and shine on the pearl's surface. High-quality pearls exhibit a sharp, bright reflection.
Alexandrite: The Color-Changing Marvel
Alexandrite is the most recent addition to the June birthstone family, added to the modern list in 1952. It is a variety of the mineral chrysoberyl and is renowned for its remarkable ability to change color depending on the light source. This phenomenon, known as the "alexandrite effect," makes the gem appear green or bluish-green in daylight or fluorescent light and red or purplish-red under incandescent light.
The gem was discovered in the Ural Mountains of Russia in the 1830s and was named after the future Tsar Alexander II. The stones were found in emerald mines and initially mistaken for emeralds due to their green color. However, upon closer inspection, particularly in candlelight, the stones revealed a distinct red hue. This dual coloration—red and green, the colors of old Imperial Russia—captivated the Tsar, and the gem became a favorite of the Russian aristocracy.
The original Russian deposits from the 19th century are largely depleted, making fine-quality Alexandrite exceptionally rare and valuable. While the Ural mines are the most famous source, significant deposits have since been found in Brazil, Sri Lanka, and East Africa. However, stones that exhibit the dramatic color change of the original Russian material are highly prized by collectors.
Symbolism and Lore of Alexandrite
Due to its discovery in Imperial Russia, Alexandrite is steeped in a sense of national pride and mysticism. It is often associated with good fortune, luck, and intuition. Russian folklore suggested that Alexandrite could foretell the future and bring balance to opposing forces, a belief likely derived from its dual nature. Metaphysically, it is considered a stone of transformation, helping the wearer adapt to change and encouraging joy and optimism.
Gemological Properties of Alexandrite
Alexandrite is a durable gemstone, making it suitable for various types of jewelry, though its rarity often places it in protective settings.
- Chemical Formula: BeAl2O4 (Beryllium Aluminum Oxide).
- Hardness: 8.5 on the Mohs scale, making it quite resistant to scratching.
- Crystal System: Orthorhombic.
- Refractive Index: 1.746 – 1.755.
- Specific Gravity: 3.73.
- Color Change: The quality of the color change is the most critical factor in valuing Alexandrite. The more distinct and saturated the colors (green in daylight, red in incandescent light), the higher the value.
Moonstone: The Ethereal Glow of Adularescence
Moonstone, the third of June's birthstones, is a variety of the mineral feldspar. It is celebrated for a unique optical phenomenon known as adularescence, which gives the stone a luminous, billowy glow that appears to move across the gem as it is rotated. This sheen is caused by the intergrowth of two different feldspar minerals, orthoclase and albite, which occur in microscopic, alternating layers. When light enters the stone, it is scattered by these layers, creating the characteristic blue or white sheen.
Moonstone's history is ancient, with connections to Roman and Greek civilizations who believed it was formed from frozen moonlight. It was a popular gem during the Art Nouveau period in the late 19th and early 20th centuries, favored by French jeweler René Lalique and his contemporaries for its dreamy, mystical appearance.
High-quality moonstone is found primarily in Sri Lanka, but significant deposits also occur in India, Madagascar, and Brazil. The finest specimens exhibit a blue sheen on a colorless or nearly colorless body. Moonstones with a cat's-eye effect or asterism (star) are also valued, though they are much rarer.
Symbolism and Lore of Moonstone
Moonstone has long been associated with the moon and the divine feminine. It is considered a stone of new beginnings, inner growth, and strength. It is strongly linked to intuition and emotional balance, believed to soothe emotional instability and provide a calming influence. In many cultures, moonstone is a traditional gift for lovers, as it is thought to ignite passion and bring about harmonious relationships.
Gemological Properties of Moonstone
Moonstone is prized for its visual appeal rather than its hardness, requiring care in jewelry settings.
- Chemical Formula: Potassium Aluminum Silicate (KAlSi3O8).
- Hardness: 6 to 6.5 on the Mohs scale.
- Crystal System: Monoclinic.
- Refractive Index: 1.518 – 1.526.
- Luster: Vitreous to pearly on the fracture surface.
- Care: Moonstone has perfect cleavage in one direction, meaning it can split if struck with sufficient force. It should be protected from hard knocks and extreme temperature changes.

Care and Maintenance of June Birthstones
Proper care is essential to maintain the beauty and longevity of these gems, particularly given their varying hardness and structural properties.
Pearl Care: Pearls are the most delicate of the three. They are highly susceptible to damage from acids, which can be found in common substances like vinegar, lemon juice, perfume, hairspray, and even perspiration. To preserve pearls, they should be the last item put on when dressing and the first removed when undressing. Clean them with a soft, damp cloth after each wear to remove body oils. Avoid ultrasonic cleaners and harsh chemicals. Store them separately from other jewelry to prevent scratching.
Alexandrite Care: As a durable gemstone with a hardness of 8.5 and no cleavage, Alexandrite is relatively easy to care for. It can be safely cleaned with warm water, mild soap, and a soft brush. It is resistant enough to be used in rings and bracelets worn daily, though standard precautions against hard impacts apply.
Moonstone Care: Moonstone requires more caution due to its perfect cleavage and moderate hardness. It should not be subjected to rough handling or sudden temperature changes. Cleaning can be done with warm, soapy water and a soft brush, but ultrasonic and steam cleaners should be avoided. It is best suited for pendants or earrings rather than rings that might receive frequent knocks.
