We will also explore how these gems are utilized in contemporary jewelry and what care they require to remain beautiful and lasting. For those born in June or for those who simply admire these stones, this piece offers a comprehensive and engaging overview of one of the most captivating groups of birthstones available.
History and Lore of June Birthstones
The tradition of assigning gemstones to specific months dates back centuries, with variations found across different cultures and historical periods. However, the modern-day birthstone list generally accepted today was formalized in the United States in 1912 by the National Association of Jewelers (now the Jewelers of America). This organization sought to standardize the list to better promote the industry while also aligning the stones with their long-standing cultural associations.
The June birthstones have had an especially dynamic presence in this tradition. Among them, the pearl is the oldest and most continuously recognized June gem. Culturally, pearls have long been symbols of purity, innocence, and wisdom. In ancient civilizations such as those of Persia and China, pearls were believed to come from the moon and were associated with divine favor and protection in times of transition. Their organic formation within mollusks has also contributed to their unique status, making them the only gemstones not formed from minerals.
Alexandrite, by contrast, is a relatively recent addition to the June birthstone roster. It was first discovered in 1830 in Russia’s Ural Mountains and became an instant source of fascination due to its rare color-changing properties. Named in honor of Czar Alexander II, the stone quickly gained popularity in royal circles and became a symbol of transformation, balance, and prosperity. However, due to its extreme rarity and the difficulty in sourcing natural alexandrite, it was incorporated into the birthstone list as a more modern and exclusive option.
Moonstone has a more mystical and spiritual legacy. Revered in many cultures for its ethereal glow and soft shimmer, it has long been associated with intuition, emotional stability, and feminine energy. The Roman naturalist Pliny the Elder once referred to moonstone as “lunar stone,” believing it was formed by the rays of the moon itself. Similarly, in ancient India, the stone was considered sacred and reserved for only the highest members of society, including royalty and priests. These rich historical associations contribute to its continued appeal and mystical aura.
Together, these three gemstones form a compelling narrative for the month of June, each representing different facets of human experience—serenity, mystery, and transformation—all while offering unique aesthetic qualities and cultural significance.
Geological Formation and Sources
Each of the June birthstones has a distinct origin and formation process, rooted in the geological history of our planet. Understanding how these gems are formed and where they are mined provides insight into their rarity and the effort required to bring them to market.
The pearl is not formed in the traditional mineralogical sense, as it is an organic gemstone produced within mollusks such as oysters, mussels, and clams. Its formation begins when an irritant, often a grain of sand, enters the mollusk’s shell. To protect itself, the mollusk secretes layers of nacre, a calcium carbonate substance. Over time, these layers accumulate into a smooth, lustrous sphere. Natural pearls are incredibly rare, while cultured pearls, which are still organic, are more widely available through controlled cultivation. Major cultured pearl producers include Japan (especially for Akoya pearls), China (freshwater pearls), and the South Pacific (for large, colorful South Sea and Tahitian pearls).
In contrast, moonstone is a mineral of the feldspar family, formed through the weathering and cooling of igneous rocks, primarily granite. Its characteristic adularescence—a soft, glowing effect under light—results from the scattering of light within the crystalline structure of the stone. This phenomenon is caused by the interplay of light and fine layers within the stone, known as tessellated layering. Moonstone is found in various regions around the world, including India, Sri Lanka, Burma, and the United States. Indian moonstone, especially from the Guntur district, is particularly renowned for its high quality and vibrant adularescence.
Alexandrite, the rarest of the June birthstones, belongs to the chrysoberyl mineral family and is composed of beryllium aluminum oxide (BeAl₂O₃). Its dramatic color change from green in daylight to red under incandescent light is due to the presence of chromium. This unique property makes alexandrite one of the rarest and most sought-after gemstones in the world. Naturally occurring alexandrite is found in only a few locations, including Brazil (the most active source), Russia (its type locality), and East Africa. The Brazilian deposits, particularly in the Minas Gerais region, produce the most highly regarded examples of the gemstone to this day.
The rarity and formation process of each gemstone influence their availability and pricing in the market. Pearls remain widely available due to modern cultivation techniques, while moonstone is also fairly accessible but of varying quality depending on the source. Alexandrite, on the other hand, is extremely rare and typically expensive, particularly in high-color-change specimens. These factors contribute to the varying degrees of popularity and usage of each stone in jewelry and other decorative or spiritual applications.
Gemological Properties
The gemological characteristics of June’s birthstones—pearl, moonstone, and alexandrite—vary significantly and contribute to their distinct appearances and practical uses in jewelry. Understanding these properties allows for better appreciation of each gemstone’s beauty and durability.
Pearls are unique among gemstones due to their organic nature. Structurally, they are composed of layers of nacre, which are made of spherical calcite crystals bound by a protein-based substance called conchiolin. It is the microstructural arrangement of these two components that gives pearls their signature luster. The hardness of pearls is relatively low, ranking between 2.5–4.5 on the Mohs scale. This makes them more susceptible to scratching and requires careful handling to prevent damage. Pearls also have a lipid layer on their surface, which can become dull over time if not properly maintained.
Moonstone is a silicate mineral of the feldspar group and has a hardness of 6–6.5 on the Mohs scale. While relatively hard for a feldspar gemstone, moonstone is quite delicate and has a pronounced cleavage, which means it can easily split along planes if struck. This makes it an ideal stone for pendants and earrings but less suitable for rings and other items that are more prone to impact. The luster of moonstone is vitreous, but it is most renowned for its adularescence—a shimmering, bandlike glow beneath the surface caused by the refraction of light through alternating layers within the stone. Moonstone also tends to be somewhat opaque, though some varieties can be translucent or even transparent.
Alexandrite is a mineral within the chrysoberyl family and has a significantly higher hardness of 8.5 on the Mohs scale, making it one of the more durable gemstones among the June line. Its refractive index is between 1.746–1.755, which contributes to its brilliant sparkle. The most notable characteristic of alexandrite, however, is its color change, the result of the way light is absorbed and reflected in the presence of the trace element chromium. Due to its hardness and toughness, alexandrite is well-suited for everyday wear in rings and bracelets, though it is most commonly found in rare and special occasion pieces due to its high cost.
Each of these gemstones reflects the diversity of the natural world, both in appearance and in the chemical and structural properties that govern their formation. These attributes also determine how each is best appreciated—pearls for their soft elegance and organic warmth, moonstone for its mystical glow and emotional energy, and alexandrite for its rare and magical color transformation.
Symbolism and Metaphysical Beliefs
Each of the June birthstones carries profound symbolic and spiritual significance, rooted in centuries of cultural beliefs, folklore, and modern metaphysical practice. These meanings have contributed to the enduring popularity of pearls, moonstone, and alexandrite not only as aesthetic accessories but also as tools for personal reflection, growth, and emotional well-being.
The pearl has long been a symbol of purity, innocence, and wisdom. In many ancient traditions, pearls were associated with the moon and were believed to represent purity of soul and serenity of mind. In Chinese culture, for example, the pearl is one of the seven treasures, and it is often linked with the jade for its calming and protective qualities. It is also thought to be a gem of luck, especially for those born in June. A popular belief is that pearls can help stabilize emotions and promote peace, making them ideal for those who seek emotional equilibrium. In Christian symbolism, the pearl represents faith and divine grace, further reinforcing its association with spiritual purity.
Moonstone is known for its connection to intuition, emotional balance, and feminine energy. As its name suggests, it has often been linked to the moon and is considered a stone of inner harmony and renewal. It is believed to enhance mental clarity, particularly during times of change, and helps individuals connect with their inner feelings and instincts. Historically, moonstone has been associated with lunar deities and was often worn during religious or spiritual ceremonies to facilitate communication with higher forces. In modern metaphysical practices, it is frequently used in meditation and chakra work, especially for the third eye and root chakras, to promote insight and emotional grounding. Some also believe moonstone is particularly beneficial for women, as it is thought to align with menstrual cycles and support reproductive health.
Alexandrite is a gemstone of transformation and duality, embodying the idea that life shifts constantly, and embracing these changes can lead to growth and prosperity. Its color change is often interpreted as a visual metaphor for the fluid nature of life and the ability to adapt to new circumstances. In the Victorian era, it was known as “Emperor’s stone” and was thought to bring good fortune, prosperity, and success. In modern crystal healing, alexandrite is used to balance physical and emotional energy and support healing after stressful or traumatic events. It is also believed to enhance creativity and intellectual vitality, often being recommended to artists, writers, and students who seek inspiration and clarity.
Each of these June birthstones, with their symbolic meanings and metaphysical properties, offers a unique energetic or emotional benefit to those who wear or use them. Whether the goal is emotional healing, intuitive enhancement, or a symbol of personal style and elegance, these gems serve as powerful allies in the journey of self-discovery and well-being.
Care and Cleaning
The care required for each of the June birthstones is determined by their hardness, cleavage, and surface characteristics, all of which influence their susceptibility to damage. Proper maintenance is essential to preserve their beauty and longevity, particularly for stones like moonstone and pearl, which have more delicate properties.
Pearls are particularly soft and porous compared to other gemstones, with a hardness rating of 2.5–4.5 on the Mohs scale. This low hardness means they can easily scratch or dull if cleaned with abrasive materials. It is also important to avoid harsh chemicals, such as chlorine, which can erode the luster of pearls over time. The best way to clean a pearl is with a soft, damp cloth to remove oils and dirt that accumulate from skin contact.Pearls should be stored separately from harder gems to prevent scratches and kept in a soft pouch or lined jewelry box. Additionally, pearls naturally lose moisture over time, so it is beneficial to occasionally expose them to a light mist of water or store them in a humidified environment.
Moonstone, like pearls, is a relatively soft gemstone, typically ranked between 6–6.5 on the Mohs scale. It is also prone to cleavage, which means it can split along internal planes if struck hard. This level of fragility requires careful handling and cleaning. It is best to clean moonstone using a damp, soft cloth, and avoid steam, excessive heat, or harsh chemicals, which can dull its adularescence. As with pearls, moonstone should be stored separately to avoid contact with harder gemstones. Some jewelers recommend avoiding exposure to prolonged sunlight or artificial light, as this can potentially fade the stone’s glow.
Alexandrite, in contrast, is significantly durability, with a hardness of 8.5 on the Mohs scale, making it suitable for everyday wear. Its cleavage is very weak, and it is generally not prone to chips or breaks under normal conditions. Despite its toughness, alexandrite should still be handled with care. Cleaning can be done with warm water and mild soap, using a soft cloth or brush, avoiding abrasive cleaners or ultrasonic cleaners, as these may damage the stone’s luster. It is also important to be mindful when exposing alexandrite to extremely high temperatures, especially during repairs or resizing, as excessive heat can affect its color change effect.
By understanding and adhering to these care guidelines, June birthstone jewelry can retain its beauty and brilliance for many years. Pearls require the most gentle treatment, while moonstone is best worn and stored with caution, and alexandrite can proudly stand the test of time with proper handling. Whether worn as pendants, rings, or earrings, each of these gemstones deserves the best care to shine in their full splendor.
