June, a month of transition and transformation, is uniquely represented in the birthstone tradition by not one, but three gemstones: pearl, moonstone, and alexandrite. For those born in the latter half of June—between June 16 and June 30—the primary birthstones are alexandrite and moonstone. These two gemstones, while distinct in their origins and properties, share a common theme of duality and change. Alexandrite, with its remarkable color-shifting abilities, and moonstone, with its ethereal glow and symbolic ties to intuition, offer wearers a unique opportunity to connect with both the physical and metaphysical aspects of gemstones.
This article explores the characteristics, historical significance, and practical care of these two June birthstones, focusing on their relevance to those born in late June. Drawing from authoritative and historical sources, we will examine their geological origins, their roles in cultural and spiritual traditions, and how they can be best appreciated and preserved in jewelry form.
The June Birthstones for Late June: Alexandrite and Moonstone
Individuals born between June 16 and June 30 have the privilege of choosing between two remarkable gemstones as their birthstone: alexandrite and moonstone. These stones, while different in appearance and composition, both embody the themes of transformation and emotional balance, making them especially fitting for those born in late June.
Alexandrite, the rarer of the two, is known for its chameleon-like ability to shift colors depending on the light source. In daylight, it appears greenish-blue, while under artificial light, it transforms into a reddish-purple hue. This phenomenon, known as color change, is due to the presence of trace elements like chromium or vanadium within its chrysoberyl crystal structure. Alexandrite was only officially recognized as a June birthstone in 1950, adding a modern touch to the month’s rich gemstone heritage.
Moonstone, in contrast, has been a traditional June birthstone since 1912. It is admired for its adularescence, a soft, glowing sheen that appears to float across the surface of the stone. This effect is caused by light scattering between layers of feldspar minerals, creating a shimmer that mimics the glow of the moon. Moonstone is often associated with intuition, emotional balance, and divine feminine energy, making it a deeply symbolic gemstone.
Together, these two stones represent a perfect blend of scientific wonder and spiritual depth, offering wearers both aesthetic appeal and emotional resonance.
History and Lore: From Ancient Symbolism to Modern Recognition
The historical significance of alexandrite and moonstone as June birthstones is rooted in their symbolic and spiritual associations. While pearl has long been linked to June, the inclusion of alexandrite and moonstone in the modern birthstone calendar reflects evolving cultural and scientific understandings of gemstones.
Alexandrite: A Modern Marvel
Alexandrite was first discovered in the Ural Mountains of Russia in 1830 and was named after the future czar, Alexander II. Its discovery was considered a national treasure, and it quickly became a symbol of royalty and transformation. The gemstone's color-changing properties were seen as a metaphor for duality and adaptability, qualities that were especially valued during the tumultuous 19th century.
Alexandrite was not officially designated as a June birthstone until 1950, when the American National Association of Jewelers (now the Gemological Institute of America) updated the list of birthstones to include it. This addition was likely due to its rarity and uniqueness, which set it apart from other stones and made it an appealing option for those seeking something distinctive.
Moonstone: A Timeless Tradition
Moonstone, on the other hand, has a much longer history. It was first recognized as a June birthstone in 1912, and its association with lunar energy and intuition dates back even further. In ancient Roman mythology, moonstone was believed to be formed from moonlight and the tears of lovers, a belief that contributed to its reputation as a stone of emotional depth and spiritual insight.
In Indian and Southeast Asian cultures, moonstone has long been associated with protection, fertility, and good fortune. It was often worn by women to balance emotions and enhance reproductive health, reflecting its strong ties to divine feminine energy.
In modern times, moonstone is often used in jewelry and crystal healing practices to promote emotional balance, inner peace, and heightened intuition. Its soft, milky appearance and iridescent sheen make it a popular choice for those who appreciate the mystical and meditative qualities of gemstones.
Geological Formation and Sources
Understanding the geological processes that create alexandrite and moonstone is essential to appreciating their rarity and beauty.
Alexandrite: A Rare and Unique Gem
Alexandrite is a variety of the mineral chrysoberyl, which is composed of beryllium aluminum oxide (BeAl₂O₄). Its color-changing effect is caused by the presence of chromium or vanadium, which absorb certain wavelengths of light and reflect others. This makes alexandrite one of the few gemstones that can alter its appearance depending on the light source.
The formation of alexandrite requires specific geological conditions, including the presence of beryllium-rich pegmatite deposits and a high-pressure, low-temperature environment. These conditions are relatively rare, contributing to the stone’s limited availability.
Today, alexandrite is found in several locations around the world, including:
- Brazil – The most significant source of alexandrite, with notable deposits in the Bahia and Minas Gerais regions.
- India – Known for producing alexandrite with a stronger color change than many Brazilian stones.
- Madagascar – A growing source of alexandrite, with stones that often exhibit a more pronounced green color in daylight.
- Russia – The original source of alexandrite, though production has declined over the years.
Due to its rarity and unique properties, alexandrite is highly valued in the gemstone market and is often considered a collector's item.
Moonstone: A Product of Nature's Layers
Moonstone is a type of feldspar mineral, and its adularescent glow is caused by the interference of light between layers of different feldspar compositions. This effect, known as adularescence, is most visible in stones with a high degree of transparency and even layering.
Moonstone is formed in granitic rocks and pegmatites, where sodium and potassium-rich feldspar minerals crystallize under slow-cooling conditions. The best moonstone is typically found in India, Sri Lanka, and the United States (especially in the state of Oregon).
Indian moonstone is especially prized for its soft blue sheen and translucent quality, while Sri Lankan moonstone is known for its high clarity and strong adularescence. In the United States, moonstone from Oregon has gained popularity in recent years for its unique colors and affordability.
Unlike alexandrite, moonstone is more widely available, though high-quality stones with strong adularescence are still considered rare and valuable.
