June is one of the few months in the calendar year that is graced with three official birthstones—pearl, moonstone, and alexandrite. Each of these gemstones brings with it a unique charm, distinct properties, and a rich historical and cultural significance. Together, they offer a diverse palette for jewelry lovers and collectors, allowing for personalization based on preference, budget, and style. In this article, we explore the origins, gemological properties, symbolism, and practical care of each of these June birthstones, drawing from authoritative sources and historical narratives that have shaped their place in the world of gems.
History and Lore
The history of June’s birthstones is as varied as the stones themselves. Pearls, perhaps the oldest and most classic of the trio, have long been associated with elegance and purity. Their formation in the soft tissues of mollusks, rather than the harsher processes that create most gemstones, has given them an almost mystical aura. Ancient cultures attributed divine origins to pearls. The Greeks believed they were the hardened tears of Aphrodite, the goddess of love, while Chinese mythology depicted them as gifts from dragons, symbols of wisdom and power. These stories reflect the reverence with which pearls were viewed, often reserved for royalty and used in significant ceremonies.
Moonstone, with its ethereal glow and iridescent sheen, has also been the subject of legend. It is said to be formed under the light of the moon, and many ancient cultures believed it was imbued with lunar energy. In India, it was considered the most sacred of all stones, and was used in religious ceremonies. In Europe, moonstone was associated with the goddess Diana and was thought to bring good fortune and protection, especially to women. This mystical quality continues to captivate modern jewelers and collectors.
Alexandrite, the youngest of June’s birthstones, was discovered much later than the others—only in the 19th century. Named after Czar Alexander II of Russia, it was discovered in the Ural Mountains in 1830. What makes alexandrite unique is its ability to change color depending on the light it is exposed to. In daylight, it appears green, but under incandescent light, it takes on a reddish-purple hue. This remarkable property earned it the nickname “emerald by day, ruby by night,” and it quickly became a prized possession among European nobility. Alexandrite was officially added to the list of June birthstones in 1952, reflecting its growing importance and desirability in the gemstone world.
The inclusion of three birthstones for June is a relatively modern phenomenon. Originally, only pearls and moonstones were considered the official birthstones. However, as alexandrite gained popularity and rarity, it was added to the list, giving those born in June an additional option for personal expression. This triad of birthstones not only reflects the diverse tastes and styles of June birthdays but also highlights the rich cultural and historical narratives that have shaped their significance over time.
Geological Formation and Sources
Each of June’s birthstones has a distinct geological origin and formation process, influenced by natural conditions and biological or mineralogical factors.
Pearls are formed within the soft tissues of mollusks such as oysters, mussels, and clams. When a foreign particle—like a grain of sand—enters the mollusk’s shell, the mollusk begins to coat it with layers of nacre, a substance secreted by the mantle. Over time, these layers build up to form a pearl. Pearls can be found in both saltwater and freshwater environments. Saltwater pearls, such as Akoya pearls from Japan, South Sea pearls from Australia, and Tahitian pearls from French Polynesia, are generally round and lustrous. Freshwater pearls, on the other hand, are often irregular in shape and can come in a wide variety of colors and forms. The process of pearl formation is slow and unpredictable, making naturally occurring pearls rare and highly valuable.
Moonstone is a type of feldspar, a mineral group that includes potassium, sodium, and calcium silicates. It is composed primarily of orthoclase and albite, which are intergrown in thin layers. The characteristic shimmer of moonstone, known as adularescence, is caused by the diffraction of light as it passes through these layers. This optical effect gives the stone its ethereal glow, reminiscent of moonlight on water. Moonstone is found in various parts of the world, including Sri Lanka, India, the United States, and Brazil. Sri Lankan moonstone is particularly prized for its high-quality adularescence and is often considered the finest in the world.
Alexandrite is a rare and valuable gemstone that belongs to the chrysoberyl family. Its color change is due to the presence of trace amounts of chromium in its crystal structure. This element affects the way light is absorbed and reflected, causing the stone to shift from green in daylight to a reddish-purple under incandescent light. Alexandrite is found in a few locations around the world, including Brazil, Madagascar, India, and Myanmar. The original deposits in the Ural Mountains in Russia have long been exhausted, making naturally occurring alexandrite increasingly rare. This scarcity, combined with its unique properties, contributes to its high value and desirability in the gemstone market.
The geological diversity of these three stones not to only reflects their unique appearances but also underscores the varied environments in which they are formed. From the deep oceans where pearls are born to the mineral-rich soils of moonstone and the rare gem-bearing deposits of alexandrite, each stone tells a story of nature’s intricate processes.
Gemological Properties
The gemological properties of June’s birthstones are as distinctive as the stones themselves, and they play a significant role in their beauty, durability, and value.
Pearls are organic gems, meaning they are formed by living organisms rather than geological processes. They are composed primarily of calcium carbonate in the form of aragonite, along with a small amount of conchiolin, a protein that binds the layers of nacre. The hardness of pearls on the Mohs scale is relatively low, ranging from 2.5 to 4.5, making them vulnerable to scratches and abrasion. Pearls are also sensitive to acidic substances, such as perfumes, lotions, and even perspiration, which can cause them to dull or erode over time. The luster of a pearl is one of its most prized characteristics, and it is influenced by the quality of the nacre and the way it is formed. Pearls can come in a variety of colors, including white, cream, pink, black, and even multicolored, depending on the species of mollusk and the environment in which they were formed.
Moonstone is a type of feldspar, a group of silicate minerals that are among the most common in the Earth’s crust. Its chemical composition is primarily a mixture of potassium and sodium silicates, which are arranged in alternating layers within the crystal structure. These layers are responsible for the optical phenomenon known as adularescence, which is the soft, glowing light that appears to float just beneath the surface of the stone. Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable compared to pearls but still susceptible to scratches and chips if not handled carefully. The color of moonstone can vary, with the most common being a milky white with a blue sheen, though other varieties include peach, gray, and even rainbow-colored moonstone. The clarity of moonstone is typically translucent to opaque, with the best specimens exhibiting strong adularescence and minimal inclusions.
Alexandrite is a gemstone of the chrysoberyl family, a mineral group that is known for its toughness and durability. Its chemical composition is beryllium aluminum oxide (BeAl₂O₄), with trace amounts of chromium responsible for its color-changing properties. On the Mohs scale, alexandrite has a hardness of 8.5 to 9, making it one of the hardest gemstones after diamonds, corundum (ruby and sapphire), and moissanite. This high hardness makes alexandrite highly resistant to scratches and wear, making it suitable for everyday jewelry. The color change in alexandrite is one of its most defining features, and it is caused by the absorption and reflection of different wavelengths of light depending on the type of light source. In daylight, the stone appears green due to the absorption of red light, while under incandescent light, it appears reddish-purple because of the absorption of green light. The intensity of the color change can vary depending on the quality of the stone and the concentration of chromium. Alexandrite is also known for its pleochroism, meaning it can display different colors when viewed from different angles, further enhancing its visual appeal.
These gemological properties not only define the physical characteristics of June’s birthstones but also influence how they are cut, set, and cared for in jewelry. Understanding these properties is essential for both gemologists and jewelry designers, as it allows for the creation of pieces that are not only beautiful but also durable and well-suited for everyday wear.
