Moonstone, a captivating gem renowned for its ethereal glow, holds a prominent place in the world of gemstones, particularly as a birthstone for June. Celebrated for its adularescence – the shimmering, billowy light that appears to emanate from within – moonstone has been steeped in mythology and lore for centuries. This article delves into the history, geological origins, gemological properties, symbolism, and care of this enchanting stone, drawing exclusively from available sources.
History and Lore
The history of moonstone is deeply intertwined with cultural beliefs surrounding the moon itself. In both Roman and Greek traditions, the gem was associated with their respective lunar deities, reflecting a perceived connection between the stone’s appearance and the celestial body. Hindu mythology attributes moonstone’s creation to solidified moonbeams, further solidifying its lunar association.
Throughout history, moonstone has been considered a stone of good luck, love, passion, and fertility. In Eastern cultures, gems exhibiting an internal light were believed to possess a powerful and benevolent spirit. In India, moonstone was held in particularly high regard, so much so that merchants were required to display it on a yellow cloth – a color considered sacred.
The gem’s significance extends beyond mere aesthetics. Magicians historically utilized moonstone in their practices, aligning its use with the phases of the moon. Waxing moons were favored for spells of increase, while waning moons were employed for spells of decrease. It was also believed that planting moonstone in a garden under a full moon would enhance its yield and fertility. Sailors and swimmers regarded moonstone as a protective talisman, owing to the moon’s influence over the planet’s waters.
During the Art Nouveau period (1890s–1910s), prominent designers like René Lalique and Louis Comfort Tiffany incorporated moonstone into their exquisite jewelry creations. The stone experienced a resurgence in popularity during the 1960s “flower child” movement and again in the 1990s with New Age designers, demonstrating its enduring appeal across different eras. In Germany and Scandinavian countries, moonstone is the preferred June birthstone, offering an alternative to pearl and alexandrite. Lovers have historically exchanged moonstones, particularly after disagreements, as a symbol of reconciliation and restored tranquility. Some believed holding the gem during a full moon and visualizing a desired love would help manifest that connection.
Geological Formation and Sources
Moonstone belongs to the feldspar group of minerals, and its unique optical phenomenon, adularescence, is what sets it apart. The gem can be found in various locations worldwide, including the United States (New Mexico, North Carolina, and Virginia), India, Sri Lanka, Brazil, Madagascar, Myanmar, and Tanzania. India and Sri Lanka are considered the most important sources for high-quality moonstone.
Gemological Properties
Moonstone typically registers between 6 and 6.5 on the Mohs scale of hardness, indicating a moderate level of durability. However, it possesses poor toughness, meaning it is susceptible to cracking when exposed to high heat. This fragility necessitates careful handling and specific cleaning methods.
The defining characteristic of moonstone is its adularescence, the shimmering effect caused by light scattering within the stone’s layered structure. The most prized moonstones exhibit a blue sheen against a colorless background. While color variations exist, the interplay of light is the primary factor determining a moonstone’s value.
Symbolism and Metaphysical Beliefs
The symbolism of moonstone is inextricably linked to the moon and its cyclical nature. The stone is often associated with intuition, dreams, and emotional balance. Its lunar connection has led to its consideration as an alternative birthstone for those born on Monday, the “Moon’s day.”
Mystics have long utilized moonstone for meditation, believing its inner light provides a focal point for concentration and promotes a calming influence, potentially aiding in achieving a trance state. Some traditions suggest moonstone can help wearers maintain a youthful appearance, mirroring the moon’s own renewal each month.
Care and Cleaning
Due to its moderate hardness and poor toughness, moonstone requires gentle care. Ultrasonic and steam cleaners should be avoided, as they can cause cracking. The recommended cleaning method involves warm, soapy water and a soft brush. This ensures the stone is cleaned without subjecting it to potentially damaging vibrations or heat.
Conclusion
Moonstone, with its captivating adularescence and rich history, remains a cherished gemstone. From its ancient associations with lunar deities and mystical practices to its enduring appeal in modern jewelry, moonstone continues to enchant and inspire. As a June birthstone, it offers a unique and beautiful alternative to pearl and alexandrite, embodying the ethereal beauty and calming energy of the moon itself. Its delicate nature necessitates careful handling, ensuring that this gem of shimmering light will be treasured for generations to come.
