For those born in the month of June, the world of gemstones offers a rare and remarkable privilege: a choice of three distinct birthstones. Unlike most months, which are traditionally linked to a single gem, June is celebrated with the organic elegance of the pearl, the enigmatic color-change of alexandrite, and the ethereal glow of moonstone. This trio provides an unparalleled variety in color, origin, and symbolism, allowing individuals to select a stone that resonates with their personal style, budget, and metaphysical inclinations. Each gemstone carries its own unique history, geological story, and set of attributes, yet all share the distinction of representing the sixth month of the year.
The existence of three June birthstones is not an arbitrary selection but a reflection of historical and practical considerations. Over time, as certain traditional stones became scarce or inaccessible, additional options were introduced to ensure that everyone born in a given month could find a suitable and available gem. For June, this has resulted in a particularly diverse group. The pearl, an organic gem formed within living mollusks, is the most classic and enduring association. Alexandrite, a variety of chrysoberyl, is famed for its dramatic shift from green in daylight to red in incandescent light, a phenomenon that has captivated gem enthusiasts since its discovery in the 19th century. Moonstone, a member of the feldspar family, exhibits a captivating blue or white sheen that seems to float across its surface, reminiscent of moonlight. Together, these stones offer a spectrum of choices, from the timeless luster of pearls to the magical color play of moonstone and the transformative beauty of alexandrite. This article will delve into the history, geology, gemological properties, and cultural significance of each of these remarkable June birthstones.
History and Lore: A Tapestry of Beliefs and Legends
The historical narratives surrounding June's birthstones are as varied as the gems themselves, spanning ancient civilizations, maritime folklore, and modern discovery. Each stone has been imbued with profound meaning and symbolism throughout human history.
The Pearl: Teardrops of Heaven and Dragon's Brains The pearl's lore is steeped in mythology and reverence. Ancient civilizations across the globe developed enchanting theories to explain the origin of these lustrous orbs. In the Middle East, a common belief held that pearls were formed from dew drops that fell from heaven and were swallowed by oysters. This celestial origin story underscores the pearl's long-standing association with purity and divinity. In ancient China, a more dramatic tale suggested that pearls originated from the brain of a dragon, a mythical creature revered for its power and wisdom. This connection to a formidable beast might explain the Chinese belief that pearls could offer protection from fire and fire-breathing dragons, with golden pearls specifically thought to bring prosperity and luck.
European explorers, too, were fascinated by the pearl's mysterious formation. Christopher Columbus and his contemporaries theorized that mollusks created pearls from dew drops, a concept that, while scientifically inaccurate, speaks to the wonder pearls inspired. Beyond these origin myths, pearls were attributed with tangible benefits. The ancient Sanskrit text, the Atharvaveda, claimed that pearls could bestow long life and prosperity. In various Asian cultures, they were believed to alleviate indigestion and hemorrhages. As recently as the 19th century, Arab physicians advocated for pearl powder as a remedy to improve eyesight, quiet nervous tremors, and ease depression. The pearl's symbolism has also been deeply tied to concepts of purity, humility, and innocence, making it a traditional wedding gift. Vedic texts describe the pearl as being born from the Earth’s waters and heaven’s powers, fertilized by lightning, further cementing its connection to elemental forces.
Alexandrite: A Serendipitous Imperial Discovery The history of alexandrite is far more recent and specific, yet no less dramatic. This gemstone was first discovered in the Ural Mountains of Russia in the early 1830s. Its unique color-changing property—appearing green in daylight or fluorescent light and shifting to a purplish-red under incandescent light—was a source of immediate fascination. The stone was named "alexandrite" in honor of the future Tsar Alexander II, whose birthday fell on the same day the gem was identified. The timing of its discovery, coinciding with the Russian national military colors (red and green), made it an instant favorite of the Russian aristocracy. This imperial endorsement solidified alexandrite's status as a gem of nobility and fortune. Its rarity and dramatic color change have led it to be associated with balance, good fortune, and the duality of nature.
Moonstone: The Luminescent Gem of the Moon Moonstone’s lore is intrinsically linked to its namesake celestial body. Hindu folklore described pearls as dewdrops from the Moon, but moonstone itself was directly associated with the moon's ethereal glow. Many cultures believed moonstone was formed from solidified moonlight, granting it a mystical connection to the night sky, intuition, and the subconscious. Its shimmering adularescence—the phenomenon of a billowy, moving light across the stone's surface—was seen as a reflection of the moon's phases, making it a powerful symbol of cyclical change, feminine energy, and emotional harmony. In ancient Rome, moonstone was admired for its beauty and was associated with the lunar deities. Its gentle, reflective quality has made it a stone of peace, calm, and heightened spiritual insight.
Geological Formation and Sources
The origins of these three gems could not be more different, spanning the biological, mineralogical, and geological realms.
Pearl: An Organic Creation Pearls are unique among birthstones as organic gems, formed not in the earth's crust but within living organisms. They are created inside the tissue of a mollusk, such as an oyster or mussel, in both saltwater and freshwater environments. A natural pearl forms when an irritant, like a grain of sand or a parasite, becomes lodged within the mollusk's soft tissue. In response, the mollusk secretes layers of nacre, a composite material primarily composed of calcium carbonate and conchiolin, which gradually coats the irritant, forming a pearl. This process can take many years. Due to overfishing and habitat destruction, natural pearls are exceedingly rare. The vast majority of pearls on the market today are cultured pearls, a product of human intervention. Technicians implant a piece of mantle tissue (for freshwater pearls) or a mother-of-pearl shell bead (for saltwater pearls) into a host mollusk, which then secretes nacre around it. These pearl farms, primarily located in saltwater and freshwater operations around the world, harvest the pearls once they have developed sufficient nacre. Freshwater cultured pearls are predominantly sourced from Chinese waters and rivers in the United States, particularly in Tennessee. Saltwater varieties include Akoya, South Sea, and Tahitian pearls, each with distinct characteristics.
Alexandrite: A Rare Mineralogical Marvel Alexandrite is a variety of the mineral chrysoberyl, with the chemical composition BeAl₂O₄. Its color-changing ability is due to the specific way its crystal structure absorbs light, a phenomenon known as pleochroism. The presence of chromium ions in its lattice is responsible for the green and red colors. The original and most prized alexandrite came from the Ural Mountains of Russia. While these deposits are largely depleted, other sources have been found, including Brazil, Sri Lanka, and East Africa. However, fine-quality alexandrite with a strong color change remains exceptionally rare, making it one of the most valuable gemstones in the world.
Moonstone: A Feldspar with a Celestial Sheen Moonstone is a variety of the feldspar mineral group, specifically orthoclase or albite. Its signature sheen, or adularescence, is caused by light scattering between microscopic layers of these two feldspar minerals within the stone. The finest moonstones exhibit a clear, blue sheen over a nearly colorless body. Historically, the finest moonstones came from Sri Lanka. However, significant deposits are also found in India (particularly in Orissa and Kerala), Madagascar, and the United States (in New York and Virginia). The quality and color of moonstone can vary significantly based on its origin.

Pearl: The Soft and Lustrous Organic Gem As an organic gem, pearl's properties are distinct from mineral stones. Its hardness, rated between 2.5 and 4.5 on the Mohs scale, makes it relatively soft and susceptible to scratching. Its chemical composition is calcium carbonate (CaCO₃) in the form of nacre. The refractive index varies depending on the quality and thickness of the nacre layers. Pearls are prized for their luster, which is the intense reflection of light from their surface, and their orient, the iridescent play of color seen in some pearls. Their specific gravity is typically between 2.72 and 2.78. The color range is vast, from classic white and cream to black, with overtones of pink, silver, and green.
Alexandrite: The Hard and Color-Changing Mineral With a hardness of 8.5 on the Mohs scale, alexandrite is exceptionally durable, suitable for all types of jewelry, including rings. Its chemical composition, BeAl₂O₄, places it in the chrysoberyl family, which also includes the cat's eye variety. The refractive index is high (1.746-1.755), contributing to its brilliance. Its most defining characteristic is its strong pleochroism, displaying green to bluish-green in daylight or fluorescent light and red to purplish-red in incandescent light. This color change is the primary factor in its value, with stones showing a more pronounced shift commanding higher prices.
Moonstone: The Soft and Sheeny Feldspar Moonstone has a moderate hardness of 6 to 6.5 on the Mohs scale, making it suitable for jewelry like pendants and earrings but requiring more care in rings. As a feldspar, its chemical composition is a mix of potassium and sodium aluminosilicates. Its refractive index is relatively low (1.518-1.526), and its specific gravity is also on the lower side (2.56-2.62). The gem's value is primarily determined by the quality of its adularescence—the blue or white sheen that appears to glide across the surface. The most sought-after moonstones have a vivid blue sheen over a transparent, colorless body. Moonstone is typically cut en cabochon (a smooth, rounded dome) to best display this optical effect.
Symbolism and Metaphysical Beliefs
Beyond their physical beauty, all three June birthstones are rich in symbolic meaning and are believed by many to possess metaphysical properties.
Pearl: Purity, Calm, and Wisdom Pearls are universally associated with purity, innocence, and humility. Their formation inside a living creature is often seen as a metaphor for hidden wisdom and the development of beauty from a place of tranquility. In metaphysical practices, pearls are believed to balance the body's natural rhythms and hormone levels, aligning them with lunar cycles. They are said to bring calm, promote faith, and induce a sense of tranquility, making them a stone for emotional balance. Some traditions connect pearls to the Third Eye Chakra, enhancing intuition and spiritual insight. Their connection to the moon further reinforces their symbolism of feminine energy, fertility, and the subconscious mind.
Alexandrite: Balance, Joy, and Transformation The dramatic color change of alexandrite has led to its symbolism of duality, balance, and the harmony of opposites. It is often called a "stone of good fortune" and is believed to bring joy and optimism to its wearer. The shift from green to red is seen as a metaphor for the balance between the material and spiritual worlds. Metaphysically, alexandrite is thought to stimulate the heart and crown chakras, fostering love, compassion, and spiritual growth. Its transformative nature makes it a powerful stone for those undergoing change or seeking to manifest their goals.
Moonstone: Intuition, Emotional Harmony, and New Beginnings Moonstone is deeply connected to the energy of the moon, symbolizing intuition, emotional harmony, and the subconscious. It is believed to enhance psychic abilities, promote lucid dreaming, and provide protection, especially during travel. As a stone of new beginnings, it is associated with inner growth, strength, and stability. Many crystal healers use moonstone to balance emotions, soothe stress, and calm overactive minds. It is often linked to the Third Eye and Crown Chakras, facilitating a connection to higher consciousness and spiritual insight. Its gentle, nurturing energy makes it a popular choice for those seeking emotional balance and a deeper connection to their inner selves.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these birthstones, with each requiring specific attention due to their distinct physical properties.
Pearl Care Due to their low hardness and porous nature, pearls require the most careful handling. They are susceptible to scratches from harder materials and can be damaged by chemicals, including acids found in cosmetics, hairsprays, and perfumes. It is recommended to put on pearl jewelry last when dressing and to remove it before swimming, bathing, or exercising. To clean pearls, simply wipe them with a soft, damp cloth after wearing. Avoid ultrasonic cleaners and harsh chemicals. Pearls should be stored separately from other jewelry to prevent scratching, preferably in a soft cloth pouch.
Alexandrite Care Alexandrite's high hardness (8.5) makes it very durable and resistant to scratching. It is an excellent choice for rings and everyday wear. However, like all gemstones, it can be damaged by sharp blows. Cleaning alexandrite is straightforward: use warm soapy water, a soft brush, and rinse thoroughly. Ultrasonic cleaners are generally safe for untreated alexandrite, but caution should be exercised with stones that have been fracture-filled. It is best to avoid sudden temperature changes.
Moonstone Care With a hardness of 6 to 6.5, moonstone is more durable than pearl but less so than alexandrite. It is important to protect moonstone from hard knocks and scratches. It is also sensitive to heat, which can cause the stone to crack, so it should not be exposed to high temperatures or rapid temperature changes. Clean moonstone with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and steam cleaning, as the vibrations and heat can damage the stone. Store moonstone separately to prevent it from being scratched by harder gems.
