June is one of the few months associated with three official birthstones: pearl, moonstone, and alexandrite. Each of these gems carries a unique set of characteristics, historical significance, and symbolic meanings that make them highly valued in jewelry, metaphysical practices, and cultural traditions. While pearl has been the traditional June birthstone for centuries, the inclusion of moonstone and alexandrite reflects the evolution of birthstone charts over time, driven by changing gemstone availability and consumer demand for variety.
This article explores the origins and history of the June birthstones, their physical and gemological properties, cultural symbolism, and practical care tips. Drawing from a range of authoritative sources, the following sections provide a comprehensive overview of what makes these stones so special, particularly for those born in June.
History and Evolution of June Birthstones
The tradition of assigning gemstones to each month of the year dates back to ancient times. One of the earliest references is found in the High Priest Aaron’s breastplate described in the Hebrew Bible, which bore 12 gemstones representing the 12 tribes of Israel. Over the centuries, this symbolic system evolved into the modern birthstone lists we recognize today.
The pearl has long been considered the primary birthstone for June, with historical records tracing its use back to ancient civilizations such as Rome, China, and the Middle East. Pearls were not only valued for their beauty but also for their symbolic associations with purity, wisdom, and humility. In ancient Rome, for example, Julius Caesar reportedly passed a law restricting the wearing of pearls to the elite, further elevating their status.
In the early 20th century, the list of birthstones was standardized by organizations such as the American National Retail Jewelers Association, which later became Jewelers of America. During this time, moonstone and alexandrite were added to the June birthstone list. Moonstone was included due to its mystical allure and iridescent glow, while alexandrite was chosen for its rare and dramatic color-changing property.
The inclusion of multiple birthstones for June was not merely symbolic—it also reflected practical considerations. As natural pearls became rarer and more expensive, jewelers sought alternative gemstones that could offer similar aesthetic and symbolic value. The addition of moonstone and alexandrite allowed for greater variety and accessibility, ensuring that June birthdays could be celebrated with a gemstone that matched the wearer’s style and budget.
Pearl: The Classic June Birthstone
Formation and Sources
Pearls are unique among gemstones because they are formed by living organisms, specifically mollusks such as oysters, mussels, and clams. When a foreign particle, such as a grain of sand, enters the soft tissue of a mollusk, it triggers a protective response. The mollusk begins to secrete nacre, a crystalline substance made of calcium carbonate (CaCO₃), around the irritant. Over time, layer upon layer of nacre builds up, eventually forming a pearl.
Unlike most gemstones that are mined from the earth, pearls are harvested from bodies of water, both saltwater and freshwater. China is the leading producer of freshwater pearls, while saltwater pearls are found in oceans around the world, including in Japan, Indonesia, Australia, and the Persian Gulf.
Gemological Properties
Pearls are relatively soft compared to other gemstones, with a hardness of 2.5 to 4.5 on the Mohs scale. This makes them more vulnerable to scratches and abrasions. They come in a wide range of colors, including white, cream, pink, black, gold, blue, and green, depending on the type of mollusk and the environment in which the pearl was formed.
Pearls are typically evaluated based on four key factors: - Luster: The sharpness and brilliance of the surface reflection. - Surface Quality: The presence of blemishes or imperfections. - Shape: From perfectly round to irregular baroque shapes. - Size: Measured in millimeters, with larger pearls generally being rarer and more valuable.
Symbolism and Cultural Significance
Throughout history, pearls have symbolized purity, innocence, and wisdom. In many cultures, they are also associated with longevity, health, and good fortune. In ancient Rome, pearls were considered a symbol of wealth and status, with laws restricting their use to the elite. In Asia, especially in China and Japan, pearls have long been associated with femininity and elegance, often used in traditional bridal jewelry.
Pearls are also associated with anniversary milestones, being the traditional gift for the 1st, 3rd, 12th, and 30th wedding anniversaries. Their enduring beauty and timeless appeal make them a popular choice for both personal adornment and sentimental gifts.
Care and Maintenance
Due to their softness and organic nature, pearls require special care to maintain their luster and longevity. They should be stored separately from other gemstones to avoid scratches, and avoid exposure to harsh chemicals, perfumes, and extreme temperatures. After wearing, pearls should be wiped gently with a soft, damp cloth to remove oils and dirt.
Moonstone: The Mystical June Birthstone
Historical and Cultural Background
Moonstone is a type of feldspar and is known for its iridescent sheen, often described as a “bluish glow” that resembles the light of the moon. This phenomenon, known as adularescence, is caused by the interference of light within the stone’s layered structure.
Moonstone has a rich history of spiritual and mystical significance. In ancient Rome, it was believed to be solidified rays of the moon, and it was associated with the power of lunar gods and goddesses. In India, moonstone was referred to as a “dream stone” and was thought to bring good dreams and visions. In Arabian culture, it was considered a fertility amulet, and some ancient beliefs even suggested that it could make the wearer invisible.
During the Art Nouveau movement of the 1920s, moonstone became a popular gemstone in jewelry design, valued for its soft, ethereal glow. Although its popularity waned in the mid-20th century, it remains a beloved birthstone for June due to its unique beauty and historical appeal.
Formation and Sources
Moonstone is found in several parts of the world, including Sri Lanka, India, Brazil, and the United States. The most prized moonstones come from Sri Lanka, where they are known for their pale blue sheen and near-translucent appearance. Moonstones from India can vary in color, including beige, green, orange, and brown.
Moonstone is formed through metamorphic processes, where feldspar minerals in igneous rocks undergo recrystallization under heat and pressure. The unique interplay of light within the stone’s structure is what gives it its mystical appearance.
Gemological Properties
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable but still susceptible to scratches and abrasions. It is often cut into cabochons to enhance its adularescent effect, and it is commonly used in rings, pendants, and earrings.
Its color variations include: - Blue sheen (most prized) - White or gray sheen - Orange or golden sheen
Symbolism and Meaning
Moonstone is often associated with femininity, intuition, and emotional balance. It is considered a stone of new beginnings, making it a fitting gemstone for June, a month that symbolizes renewal and growth. In modern metaphysical practices, moonstone is believed to calm the mind, enhance intuition, and promote emotional stability.
It is also considered a stone of love, especially in new relationships, where it is said to foster trust and understanding. In feng shui, moonstone is believed to attract positive energy and enhance prosperity.
Care and Maintenance
Moonstone should be stored separately from harder gemstones to avoid scratches. It is not recommended to use ultrasonic cleaners on moonstone, as the vibrations can damage its structure. Instead, it should be cleaned with warm water and a soft cloth. Moonstone is also sensitive to extreme temperatures, so it should be avoided exposure to heat or cold.
Alexandrite: The Rare and Color-Changing June Birthstone
Discovery and Historical Significance
Alexandrite is the youngest of the three June birthstones, having been discovered in the 1830s in Russia. It was named after Tsar Alexander II, who was celebrating his 17th birthday at the time of its discovery. Alexandrite quickly gained royal favor, becoming a popular gemstone among European nobility.
What makes alexandrite truly unique is its remarkable color-changing property. It appears green in daylight and red in incandescent light, a phenomenon known as pleochroism. This effect is caused by the presence of chromium in the stone’s composition.
Alexandrite was officially added to the June birthstone list in the 1950s, when its rarity and beauty made it a desirable alternative to pearls, especially as natural pearls became scarcer and more expensive.
Formation and Sources
Alexandrite is a rare variety of chrysoberyl, a hard and durable mineral with the chemical formula BeAl₂O₄. It is found in a few specific locations around the world, including: - Russia (original source) - Brazil - India - Madagascar - Myanmar
The most highly prized alexandrite is from Brazil, where the strongest color change and highest clarity are found. The Russian deposits, while historically significant, are now limited due to mining restrictions.
Alexandrite forms in granitic pegmatites, a type of igneous rock that cools slowly, allowing large, well-formed crystals to develop. The presence of chromium in the rock is what gives alexandrite its unique color-changing properties.
Gemological Properties
Alexandrite is exceptionally hard, with a hardness of 8.5 on the Mohs scale, making it very durable and suitable for everyday wear. It is typically cut into faceted stones to best showcase its color-changing effect.
The most valuable alexandrite displays a vivid green in daylight and a deep red in incandescent light. The intensity of the color change and the clarity and size of the stone determine its market value.
Symbolism and Meaning
Alexandrite is often associated with luck, prosperity, and transformation, making it a fitting symbol for June, a month of change and growth. In modern metaphysical beliefs, it is considered a stone of balance, helping to harmonize the mind and body.
It is also known as the “stone of love”, where it is believed to enhance emotional connections and deepen relationships. In feng shui, alexandrite is used to attract good fortune and success, especially in business and career pursuits.
Alexandrite is also associated with intellect and creativity, making it a popular choice for gifts to scholars, artists, and professionals.
Care and Maintenance
Due to its high hardness and durability, alexandrite is relatively easy to care for. It can be cleaned with warm water and a soft cloth or ultrasonic cleaner, though it is not sensitive to harsh chemicals. It should be stored in a soft pouch to prevent scratches from other gemstones.
Alexandrite is also relatively stable in terms of temperature, though it should be avoided exposure to extreme heat, as this can affect its color change.
