The month of June is uniquely distinguished in the world of gemstones by its association with not one, but three official birthstones: pearl, moonstone, and alexandrite. This official trinity offers a spectrum of color and luster, from the organic luminescence of pearls to the rare color-changing phenomenon of alexandrite. However, the commercial and cultural landscape of birthstones, particularly in the context of personalized jewelry, often presents variations on these traditional stones. An examination of modern jewelry market trends reveals a significant presence of "Light Amethyst" and "Ivory Mother-of-Pearl" as alternative or popular choices for June, especially in the realm of sentimental, customized gifts. This article provides a detailed exploration of the traditional June birthstones, while also contextualizing the modern alternatives that have become prominent in consumer-focused collections. We will delve into their geological origins, gemological properties, historical lore, and the profound symbolism they carry, particularly within the cherished tradition of mother's jewelry.
Historical Foundations and the Evolution of June's Gems
The concept of a specific birthstone for each month has ancient roots, but the modern, standardized lists are a relatively recent development. The most widely recognized list, which includes pearl, moonstone, and alexandrite for June, was formalized in 1912 by the American National Retail Jewelers Association (now Jewelers of America). This list was created to provide a clear guide for the jewelry industry and consumers. However, the history of these stones as talismans and objects of adornment stretches back millennia.
Pearls, the oldest known gem, have been prized since at least 2206 BC, according to historical accounts from China. Ancient Romans held pearls in the highest esteem, viewing them as the ultimate symbol of wealth and social standing. The Roman biographer Suetonius wrote that the general and statesman Vitellius financed an entire military campaign by selling just one of his mother's pearl earrings. Pearls were associated with the moon and were believed to possess properties that could calm tides and influence emotions. Their organic origin, formed within a living creature, gave them an almost mystical quality, setting them apart from gems mined from the earth.
Moonstone, a member of the feldspar mineral family, derives its name from its captivating visual effect, known as adularescence. This optical phenomenon creates a billowy, moving light across the surface of the stone, reminiscent of the moon's glow passing through high, thin clouds. Ancient Romans believed moonstone was formed from solidified moonlight, and they associated it with their lunar deities. Throughout history, it has been a stone of prophecy and a conduit for passionate love. In India, moonstone is considered a sacred and magical gem, and it is said to bring good fortune to those who wear it.
Alexandrite is the most recent addition to the June trio, with a history that begins in the early 1830s in Russia's Ural Mountains. The gem was discovered on the future Tsar Alexander II's birthday and was subsequently named in his honor. Its most remarkable property is its ability to appear in different colors under different light sources: green in daylight or fluorescent light and red to purplish-red under incandescent light. This dramatic color change, mirroring the old imperial Russian military colors, made it the national stone of tsarist Russia and a symbol of patriotic pride. Its lore is intertwined with notions of duality, balance, and hope.
Geological Formation and Global Sources
Understanding the origins of these gems reveals a fascinating contrast between organic creation, geological processes, and rare coincidences.
Pearls: Organic Wonders
Unlike other gemstones, pearls are not mined from the earth. They are the product of a biological process within mollusks, such as oysters and mussels. A natural pearl forms when an irritant, like a parasite or a piece of shell, becomes lodged in the mollusk's soft tissue. To protect itself, the mollusk secretes layers of nacre—a composite of aragonite (a form of calcium carbonate) and conchiolin (an organic protein)—around the irritant. This slow, layer-by-layer deposition creates the pearl. The vast majority of pearls on the market today are cultured pearls, where a human intentionally introduces a nucleus (often a bead of polished shell) into the mollusk to initiate the process. Major sources for both natural and cultured pearls include the Persian Gulf, the waters off Japan, Australia, and various regions in Southeast Asia and the South Pacific.
Moonstone: A Product of Geologic Time
Moonstone is a variety of the mineral feldspar, specifically orthoclase or albite. Its formation is a result of geological processes that create certain types of granite and metamorphic rocks. As molten rock cools, the feldspar minerals crystallize. The unique internal structure of moonstone, which consists of alternating layers of orthoclase and albite, is what causes its signature adularescence. Light scatters between these microscopic layers, producing the ethereal glow. Historically, the finest moonstones were sourced from the mountains of Sri Lanka, but significant deposits are also found in India, Brazil, and the United States (in Virginia and the Carolinas).
Alexandrite: A Happy Geological Accident
Alexandrite is a variety of the mineral chrysoberyl. Its formation requires the presence of beryllium and chromium—two elements that rarely occur together in nature. The specific geological conditions that allow for their coexistence are exceptionally rare, which accounts for the gem's scarcity. The chromium that causes the color change in alexandrite absorbs red and yellow light while allowing green light to pass through. Under incandescent light, which is rich in red wavelengths, the stone appears red. The original Ural Mountain deposits, which produced the finest alexandrite, are now largely depleted. Today, significant sources include Brazil, Sri Lanka, and various locations in Africa (Madagascar, Tanzania, Zimbabwe).
The Alternative June Stones: Light Amethyst and Mother-of-Pearl
While the traditional list is well-established, the jewelry market, especially for personalized and gift-oriented pieces, often features alternatives that align with consumer preferences for color and symbolism.
Light Amethyst
Amethyst is the purple variety of quartz, colored by trace amounts of iron and other impurities. Its color can range from a deep, royal violet to a very pale, delicate lilac. "Light Amethyst" refers to the latter end of this spectrum. While amethyst is the official birthstone for February, its soft purple hue is sometimes marketed for June. In the context of mother's jewelry and customizable necklaces, light amethyst provides a gentle, feminine color that can be easily incorporated into multi-stone designs. Its relative affordability and wide availability make it a popular choice for creating sentimental pieces that represent family members.
Ivory Mother-of-Pearl
Mother-of-Pearl, or nacre, is the iridescent substance that forms the inner lining of the shells of certain mollusks. It is the same material that constitutes a pearl. As a gemstone, it is typically cut from the shell itself, rather than being a standalone sphere. It displays a soft, milky iridescence with pastel hues of white, pink, and green. In the provided sources, Kendra Scott's June collection features an "Ivory Mother-of-Pearl" stone. This choice is significant because it connects directly to the organic nature of the traditional pearl, offering an alternative with a similar lustrous quality but in a different form and color palette. Its creamy, neutral tone makes it exceptionally versatile for jewelry design.

Symbolism and Metaphysical Beliefs
Across cultures and centuries, gemstones have been imbued with powerful symbolic meanings and metaphysical properties.
Pearls are universally associated with purity, innocence, and faith. Because they are formed within a living creature, they have long been linked to the moon, which governs the tides and is thought to influence emotions. In many traditions, pearls are believed to have a calming effect, balancing one's karma and strengthening relationships. They are often used to soothe the wearer and bring clarity of mind.
Moonstone is considered a stone of new beginnings and inner growth. Its connection to the moon makes it a powerful talisman for enhancing intuition and promoting success in love and business. It is often called the "stone of lovers," believed to rekindle passion and bind lovers together. Spiritually, it is thought to soothe emotional instability and stress, providing a sense of calm and balance.
Alexandrite is a stone of duality and transformation, reflecting its own dramatic color change. It is associated with joy, optimism, and creativity. Legend holds that it can bring good fortune and abundance to its wearer. Because it embodies both the energy of the green light (nature, life) and the red light (passion, vitality), it is believed to balance the physical and spiritual realms, fostering harmony between the mind and the heart.
In the modern context of personalized jewelry, the symbolism of birthstones takes on a more intimate meaning. A necklace featuring the birthstones of a mother's children is not just an accessory; it is a tangible representation of the family bond. Each stone becomes a symbol of an individual's identity within the family unit, and the collective piece represents the unifying love of the mother. This is a powerful modern interpretation of the ancient tradition of wearing birthstones for protection and good fortune.
Care and Cleaning
The durability of a gemstone dictates how it should be cared for. Proper maintenance is essential to preserve the beauty and integrity of birthstone jewelry.
Pearls and Mother-of-Pearl (Hardness 2.5-4.5): These organic gems are the most delicate of the birthstones. They are soft and can be easily scratched by sharper, harder objects. They are also susceptible to damage from chemicals, including perfume, hairspray, and even the acids in human perspiration. Clean them with a soft, damp cloth after each wear. It is crucial to put pearl jewelry on last, after applying cosmetics, and to store it separately from other jewelry to prevent scratches.
Moonstone (Hardness 6.0-6.5): Moonstone is relatively durable but can be prone to cleavage, meaning it can break along internal planes if struck with force. It should be protected from hard blows. Cleaning can be done with warm, soapy water and a soft brush. Avoid ultrasonic and steam cleaners.
Alexandrite (Hardness 8.5): As one of the most durable birthstones, alexandrite is excellent for everyday wear, including in rings. It is resistant to scratching and can be cleaned with warm, soapy water and a soft brush. It is also generally safe to use an ultrasonic cleaner.
Light Amethyst (Hardness 7.0): Amethyst is also quite durable and suitable for daily wear. It can be cleaned using warm, soapy water and a soft brush. While it is resistant to most chemicals, prolonged exposure to strong sunlight or high heat can cause its purple color to fade, so it is best to store it away from direct light when not in use.
