Whether you're a jewelry buyer, a gemology student, or simply someone captivated by the beauty of June birthstones, this article offers a comprehensive look at what makes these earrings so special.
History and Lore
The tradition of birthstones dates back thousands of years, with roots in ancient civilizations such as the Hebrews and the Chinese. However, the modern concept of birthstones as we know it today was popularized in the United States in the early 20th century by the Jewelers of America, which began standardizing the list of birthstones in 1912. June has been associated with two gemstones—pearl and moonstone—since at least the mid-20th century. The inclusion of both stones reflects their distinct yet complementary qualities, making them ideal for a month known for summer beginnings and personal growth.
Pearl has been revered for millennia. Ancient Greeks believed pearls were the tears of the gods, while in Chinese culture, they symbolized wisdom and purity. The Roman naturalist Pliny the Elder, in his Natural History, noted that pearls were formed from sea foam and the tears of virgins—myths that persisted for centuries. During the Renaissance, pearls became a symbol of status and virtue, often worn by royalty and the nobility. Their association with purity and innocence continues to this day.
Moonstone, on the other hand, has long been associated with the moon and feminine energy. In ancient Rome, it was believed to be formed from moonlight, and it was thought to bring good fortune to travelers. In India, moonstone is one of the 12 sacred stones of Hindu astrology, associated with the moon god Chandra. The gemstone was also popular in Victorian England, where it was used in sentimental jewelry, especially in pieces made during the Romantic era. Its ethereal glow, known as "adularescence," made it a favorite among jewelers and a symbol of love and protection.
Together, pearl and moonstone represent a balance of earthly and celestial beauty. Their inclusion in June’s birthstone tradition reflects the duality of the season—both the warmth of summer and the lingering grace of spring.
Geological Formation and Sources
Understanding the geological origins of pearl and moonstone helps to appreciate the rarity and value of June birthstone earrings.
Pearl
Pearls are organic gemstones formed within the soft tissue of mollusks, primarily oysters and mussels. The process begins when an irritant, such as a grain of sand, enters the mollusk's mantle tissue. To protect itself, the mollusk secretes layers of nacre—a combination of aragonite, conchiolin, and water—around the irritant. Over time, these layers build up to form a pearl.
The most valuable pearls are natural, but the majority of pearls available today are cultured. Cultured pearls are formed when a bead nucleus is inserted into the mollusk, prompting the same nacre-building process. The result is a gemstone with a similar structure and beauty to a natural pearl, but with more predictable size, shape, and color.
Freshwater pearls, commonly used in June birthstone earrings, are produced in mussels found in rivers and lakes, particularly in China, the United States, and Europe. Saltwater pearls, such as the renowned South Sea and Akoya pearls, are formed in oceanic oysters, primarily in regions like Australia, Japan, and Indonesia.
The color of a pearl can vary widely, from white and cream to black and pink. The luster, or the quality of light reflected from the surface, is a key factor in determining a pearl’s value. High luster pearls have a mirror-like sheen, while lower luster pearls may appear dull or chalky.
Moonstone
Moonstone is a type of feldspar, a group of silicate minerals that are among the most common in the Earth's crust. The specific variety of feldspar that forms moonstone is orthoclase, which exhibits adularescence—the soft, glowing effect that gives the gemstone its name. This optical phenomenon is caused by the intergrowth of two feldspar minerals, which scatter light as it passes through the stone.
Moonstone is typically found in metamorphic and igneous rocks, particularly in pegmatites—coarse-grained igneous rocks that form from the slow cooling of magma. The most prized moonstone for jewelry is found in India, where it has been mined for centuries. Other notable sources include Brazil, Sri Lanka, and the United States.
The color of moonstone can range from white and gray to blue, peach, and even green. The most valuable moonstones display a strong blue adularescence and a transparent to translucent body. These qualities make them especially well-suited for use in earrings, where their ethereal glow can be highlighted in a delicate setting.
Gemological Properties
The gemological properties of pearl and moonstone are what make them unique and suitable for use in earrings, especially when paired with gold.
Pearl
Pearls are unique in the gemstone world because they are the only organic gemstones. Their chemical composition is primarily calcium carbonate (CaCO₃), which is the same as limestone and marble. However, pearls differ in that they are formed in a living organism and have a layered structure that gives them their luster.
Pearls have a hardness of 2.5 to 4.5 on the Mohs scale, which is relatively low. This means they are soft and can be easily scratched or damaged by harsh chemicals or abrasive materials. For this reason, pearls require special care when worn and cleaned. They are also sensitive to changes in temperature and humidity, which can cause them to dry out or become brittle.
The size, shape, and color of a pearl can vary widely. Round pearls are the most valuable, but other shapes such as oval, drop, and baroque pearls are also used in jewelry. The surface of a pearl is another key factor in its value. High-quality pearls have a smooth, blemish-free surface, while lower-quality pearls may have pits, ridges, or other imperfections.
Because of their softness and sensitivity, pearls are best suited for jewelry that is worn close to the body, such as earrings. The setting should be secure to prevent the pearls from rubbing against other surfaces or becoming dislodged.
Moonstone
Moonstone is a silicate mineral with the chemical formula KAlSi₃O₈. It belongs to the feldspar group and is composed primarily of potassium aluminum silicate. The intergrowth of different feldspar minerals within the stone causes the adularescence, or the floating light effect that is so characteristic of moonstone.
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, which is moderate. While not as hard as diamonds or sapphires, moonstone is still durable enough to be used in everyday jewelry. However, like all feldspar gemstones, it is susceptible to scratches and can be damaged by exposure to heat or chemicals. It is also slightly porous, which can allow it to absorb oils and lotions over time.
The refractive index of moonstone ranges from 1.518 to 1.526, which contributes to its soft, glowing appearance. The most desirable moonstones are those that display a strong blue adularescence and have a transparent to translucent body. These characteristics make moonstone ideal for use in earrings, where the light effect can be fully appreciated.
The color of moonstone can vary depending on the impurities and the structure of the stone. The most valuable moonstones display a strong blue adularescence with a white or gray body. Other colors, such as peach, yellow, and green, are also found but are generally less valuable.
Symbolism and Metaphysical Beliefs
The symbolic and metaphysical meanings of pearl and moonstone have been passed down through centuries and are still relevant today, especially in the context of June birthstone earrings.
Pearl
Pearls have long been associated with purity, innocence, and wisdom. In many cultures, they symbolize the tears of joy, the essence of the sea, and the feminine principle. The ancient Greeks believed that pearls were the solidified tears of the gods, while the Romans thought they were formed from sea foam and the tears of virgins. In Chinese culture, pearls were associated with the moon and were believed to bring longevity and good fortune.
In the Middle Ages, pearls were seen as a symbol of divine grace and spiritual purity. They were often worn by royalty and the nobility as a sign of virtue and status. During the Renaissance, pearls became a symbol of wealth and power, especially among the European aristocracy.
In modern times, pearls continue to be associated with elegance, refinement, and sophistication. They are often given as gifts to mark significant milestones, such as a birthday, an anniversary, or a coming-of-age ceremony. As a June birthstone, pearl represents the qualities of growth, harmony, and wisdom—making it a fitting symbol for those born in the month of June.
Moonstone
Moonstone has a rich history of symbolic and metaphysical associations, particularly in relation to the moon, femininity, and intuition. In ancient Rome, it was believed that moonstone was formed from moonlight, and it was used by travelers to bring good fortune and protection. In India, it is considered one of the 12 sacred stones of Hindu astrology and is associated with the moon god Chandra. It is believed to enhance emotional balance and support the cycles of the moon and the body.
In Victorian England, moonstone was often used in sentimental jewelry, especially in pieces made during the Romantic era. It was associated with love, romance, and the mystical. Its ethereal glow made it a favorite among jewelers, and it was often set in gold or silver for a subtle, elegant effect.
Today, moonstone is still valued for its calming and protective properties. It is believed to promote balance, intuition, and inner harmony. As a June birthstone, moonstone represents the qualities of intuition, sensitivity, and emotional depth—making it a powerful symbol for those born in the month of June.
Craftsmanship and Design
The design and craftsmanship of June birthstone earrings are as important as the gemstones themselves. Whether the earring features a pearl or a moonstone, the setting, materials, and construction play a significant role in the overall appearance and durability of the piece.
Pearl Earrings
Pearl earrings are typically made with either natural or cultured pearls, depending on the desired quality and price. The pearls are set into a secure backing, often in a stud or button design, to prevent them from becoming dislodged. The backing is usually made from metal, such as gold, silver, or platinum, and may include a tension setting or a post and butterfly clasp.
In June birthstone earrings, the pearls are often paired with gold, either in gold-fill, gold vermeil, or solid gold. Gold-fill is a cost-effective alternative to solid gold, as it consists of a thick layer of gold bonded to a base metal. Gold vermeil is another popular option, consisting of a sterling silver base with a thick layer of 18k gold plating. Both options offer the look and feel of solid gold while being more affordable.
The setting should be carefully crafted to ensure that the pearl is secure and not exposed to excessive wear. Because pearls are soft and sensitive, they should be worn in a setting that protects them from scratches and abrasions. Earrings that are worn frequently should be designed with this in mind, using materials that are both durable and gentle on the pearls.
Moonstone Earrings
Moonstone earrings are often set in a prong or bezel setting to showcase the gemstone’s glow. The prong setting allows for maximum light exposure, enhancing the adularescence of the stone. The bezel setting, on the other hand, provides a secure and protective frame for the moonstone, making it a good choice for everyday wear.
In June birthstone earrings, moonstone is frequently paired with gold, either in gold-fill, gold vermeil, or solid gold. The gold setting complements the soft, ethereal glow of the moonstone, creating a harmonious and elegant piece. The setting may include additional design elements, such as engraved patterns or textured surfaces, to add depth and visual interest to the earring.
Because moonstone is a relatively soft gemstone, it is important to choose a setting that provides adequate protection. Earrings that are worn frequently should be designed with a secure and durable setting to prevent the moonstone from becoming dislodged or damaged. The use of high-quality materials and skilled craftsmanship ensures that the earring not only looks beautiful but also lasts for years to come.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of June birthstone earrings, especially when they contain pearls or moonstone. These gemstones require special attention due to their softness and sensitivity to environmental factors.
Pearl Earrings
Pearls are particularly sensitive to changes in temperature, humidity, and exposure to chemicals. They should be stored in a soft, breathable pouch or a jewelry box to prevent them from drying out or becoming scratched. It is also important to avoid storing pearls in airtight containers, as this can cause them to lose their luster.
When cleaning pearl earrings, it is best to use a soft, damp cloth to gently wipe away any dirt or oils. Harsh chemicals, ultrasonic cleaners, and steam cleaners should be avoided, as they can damage the nacre and cause the pearls to become dull or discolored. It is also advisable to remove pearl earrings before applying cosmetics, lotions, or perfumes, as these can leave a residue on the surface of the pearls.
Pearls should be worn periodically to maintain their luster and prevent them from becoming brittle. The natural oils from the skin can help keep the pearls hydrated and fresh. If pearls become dull or discolored over time, they can be professionally cleaned by a jeweler who specializes in pearls.
Moonstone Earrings
Moonstone is more durable than pearls, but it is still sensitive to heat, chemicals, and physical damage. It should be stored in a cool, dry place away from direct sunlight and other gemstones that may scratch its surface. A soft pouch or a jewelry box with individual compartments is ideal for storing moonstone earrings.
When cleaning moonstone earrings, it is best to use a soft, damp cloth to gently wipe away any dirt or oils. Harsh chemicals and ultrasonic cleaners should be avoided, as they can dull the stone's luster and damage the surface. Moonstone should also be kept away from abrasive materials, as it can be scratched by harder gemstones such as diamonds or sapphires.
Moonstone can be worn on a regular basis, but it should be removed before engaging in activities that may expose it to impact or friction. If moonstone becomes dull or discolored over time, it can be professionally cleaned by a jeweler who specializes in feldspar gemstones.
