June 17th is a date distinguished by a unique duality in birthstone tradition, as it is associated with two remarkable gemstones: the pearl and alexandrite. These stones represent contrasting yet complementary aspects of gemstone diversity—pearls, with their soft, luminous beauty and organic origins, and alexandrite, known for its rare and mesmerizing color-changing properties. Together, they offer a rich tapestry of meaning, history, and symbolism, making June 17th a date of particular interest in the world of birthstones.
This article explores the characteristics, origins, and significance of both pearls and alexandrite, drawing from historical accounts, geological data, and cultural traditions. The discussion encompasses their symbolic meanings, gemological properties, and practical care tips, providing a comprehensive overview for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
The tradition of birthstones dates back centuries, rooted in ancient beliefs that specific gemstones held protective and symbolic powers for individuals born under certain months or dates. For those born on June 17th, the association with pearls and alexandrite reflects both ancient reverence and modern appreciation.
Pearls have long been regarded as symbols of purity, wisdom, and natural elegance. In many ancient cultures, they were believed to possess mystical properties. The Greeks, for example, saw pearls as the hardened tears of joy from Aphrodite, the goddess of love. In Chinese mythology, pearls were thought to originate from the brain of a dragon, a symbol of wisdom and power. These beliefs contributed to the widespread admiration for pearls among royalty and the elite throughout history.
Alexandrite, in contrast, is a much younger gemstone in the birthstone tradition. Discovered in the 1830s in Russia, it was named after Czar Alexander II, and it quickly gained favor among European aristocracy. Its remarkable ability to shift color—green in daylight and red under incandescent light—was considered magical and rare. By the 1950s, alexandrite was officially recognized as a June birthstone, adding another layer of meaning and beauty to the month’s gemstone heritage.
The inclusion of both pearls and alexandrite for June 17th reflects the evolving nature of birthstone traditions. While pearls were historically the sole June birthstone, the addition of alexandrite in the mid-20th century provided greater variety and appeal, especially as natural pearls became rarer and more expensive.
Geological Formation and Sources
Pearls
Pearls are unique among gemstones in that they are organic gems formed within living organisms—specifically mollusks such as oysters, mussels, and clams. The formation of a pearl occurs when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk secretes layers of nacre, a substance composed of aragonite (a form of calcium carbonate) and conchiolin (a protein), around the irritant. Over time, these layers build up to form a smooth, spherical pearl.
Pearls can be found in both saltwater and freshwater environments. Saltwater pearls are primarily produced by oysters in regions such as the Persian Gulf, the South Pacific, and the Caribbean. Freshwater pearls, on the other hand, are formed in mussels and are commonly found in lakes and rivers in China, Japan, and the United States.
The majority of pearls available today are cultured pearls, meaning they are produced with human intervention to increase the likelihood of pearl formation. This process does not harm the mollusk and has made pearls more accessible to the general public while maintaining their natural beauty.
Alexandrite
Alexandrite is a rare and unique mineral composed of beryl (chemical formula BeAl₂O₄) with trace amounts of chromium or vanadium, which are responsible for its color-changing properties. It forms in metamorphic rocks, particularly in regions where pegmatite deposits are present. Pegmatites are igneous rocks that form from the slow cooling of magma and are known for containing large, well-formed crystals.
The first alexandrite was discovered in the Ural Mountains of Russia in the 1830s. However, these deposits were depleted by the mid-20th century, and most alexandrite now comes from Brazil, India, and Sri Lanka. Brazilian alexandrite is particularly prized for its vivid green and red color change.
Unlike pearls, which are organic and require living organisms to form, alexandrite is a mineral that forms deep within the Earth’s crust. Its rarity and unique optical properties make it a highly sought-after gemstone, especially among collectors and connoisseurs of rare gems.
Gemological Properties
Pearls
Pearls are distinguished by their luster, which is the result of the way light reflects off the layers of nacre. They have a smooth, pearly luster that is often described as "orient," a soft iridescence that gives them a dreamy, ethereal quality. Pearls are relatively soft compared to other gemstones, with a hardness of 2.5 to 4.5 on the Mohs scale. This means they can be scratched by harder materials and require gentle handling.
Pearls are graded based on several factors, including shape, size, color, luster, and surface quality. The most valuable pearls are round, large, and have a high luster with minimal imperfections. Pearls can come in a range of colors, including white, cream, pink, lavender, and black, depending on the type of mollusk and the environment in which they were formed.
Because pearls are organic, they can absorb oils and chemicals from the environment. This makes them sensitive to harsh cleaning agents and can affect their longevity over time. For this reason, pearls should be cleaned with a soft cloth and mild soap, and they should be stored separately from other jewelry to prevent scratches.
Alexandrite
Alexandrite is one of the most unique gemstones due to its color-changing properties. In daylight, it appears green due to the absorption of red light by chromium or vanadium. In incandescent light, it appears red or purple because it absorbs blue light. This phenomenon is known as the "alexandrite effect" and is caused by the selective absorption of light at different wavelengths.
Alexandrite has a hardness of 8.5 to 9 on the Mohs scale, making it relatively durable and suitable for use in jewelry. It is also pleochroic, meaning it can display different colors when viewed from different angles. This adds to its visual complexity and makes each alexandrite gemstone unique.
Alexandrite is transparent to translucent and has a vitreous (glassy) luster. Its refractive index ranges from 1.74 to 1.76, and it has a specific gravity of 3.70 to 3.78, which is higher than many other gemstones. These properties help gemologists distinguish alexandrite from other beryl varieties and synthetic imitations.
Due to its rarity and value, alexandrite is often cut in a cushion or emerald shape to enhance its color change and minimize surface damage. Properly cut alexandrite can display its full range of colors, making it a captivating gemstone for collectors and jewelry enthusiasts.
Symbolism and Metaphysical Beliefs
Both pearls and alexandrite carry rich symbolic meanings and have been associated with various metaphysical beliefs across cultures and time periods.
Pearls
Pearls have long been associated with purity, innocence, and spiritual wisdom. In ancient Greece, they were believed to be the tears of the gods, particularly Aphrodite, and were considered symbols of love and beauty. In China, pearls were revered as symbols of wisdom and longevity, often used in imperial jewelry and religious ceremonies. The soft, luminous quality of pearls was thought to reflect inner peace and emotional balance.
In modern metaphysical practices, pearls are believed to promote calmness and emotional stability. They are often used in crystal healing to soothe the heart and enhance intuition. Pearls are also associated with feminine energy and are believed to help those seeking to express themselves more freely and authentically.
Alexandrite
Alexandrite is associated with transformation, adaptability, and balance. Its ability to change color is seen as a metaphor for personal growth and resilience. In many cultures, alexandrite is believed to bring good fortune and protection, especially during times of change or uncertainty.
In Russian folklore, alexandrite was believed to be a lucky stone, bringing prosperity and success to those who owned it. It was often given as a gift during important life transitions, such as weddings, promotions, or new ventures. In modern crystal healing, alexandrite is used to support emotional healing, enhance creativity, and promote a sense of purpose and direction.
Both pearls and alexandrite offer complementary energies that can support individuals in different ways. Pearls promote emotional calm and inner wisdom, while alexandrite encourages transformation and adaptability. Together, they create a powerful combination that reflects the duality of June 17th's birthstone tradition.
Care and Cleaning
Proper care and cleaning are essential to preserving the beauty and longevity of both pearls and alexandrite.
Pearls
Because pearls are soft and sensitive, they require gentle handling and cleaning. Avoid exposing pearls to harsh chemicals, perfumes, or lotions, as these can dull their luster or cause damage. After wearing pearls, it is best to wipe them with a soft, dry cloth to remove any oils or residues.
When storing pearls, keep them separate from other jewelry to prevent scratches. A soft pouch or a lined jewelry box is ideal. Avoid exposing pearls to extreme temperatures or humidity, as this can cause them to dry out or become brittle over time.
Alexandrite
Alexandrite is more durable than pearls, but it still requires care to maintain its brilliance. Clean alexandrite with a soft brush and mild soap, using warm water to remove dirt and debris. Avoid using ultrasonic cleaners or steam cleaners, as these can cause damage or affect the gemstone’s color change.
When storing alexandrite, keep it in a secure place to prevent scratches and impacts. A velvet-lined jewelry box or a padded compartment is recommended. Avoid exposing alexandrite to prolonged exposure to direct sunlight or artificial light, as this can affect its color-changing properties over time.
By following these care tips, individuals can ensure that their pearls and alexandrite remain beautiful and valuable for years to come.
