June 15th is a day marked by a unique gemstone that reflects the dynamic and intuitive energy of those born under the zodiac sign of Gemini. The birthstone for June 15th is Moonstone, a gemstone renowned for its shimmering, iridescent sheen and its deep connection to emotional balance and intuition. As one of the three official birthstones for the month of June, alongside Pearl and Alexandrite, Moonstone holds a special place in both historical tradition and modern gemology.
Moonstone is a feldspar mineral known for its adularescence — a soft, glowing light that appears to float just beneath the surface of the stone. This phenomenon, caused by the diffraction of light through microscopic layers within the gem, gives Moonstone its dreamlike, ethereal quality. It has been cherished for centuries across cultures for its beauty, symbolism, and spiritual properties.
In this article, we explore the rich history, geological formation, gemological properties, and cultural significance of Moonstone, especially as it pertains to those born on June 15th. We also examine its role in jewelry and how it is best cared for, ensuring its beauty endures for generations.
History and Lore
Moonstone has long been associated with the moon, fertility, and feminine energy. Ancient Roman and Indian cultures revered the stone, believing it to be formed from solidified moonlight. In India, it was considered sacred and often used in religious and ceremonial settings. The Romans associated Moonstone with the moon goddess Diana and believed it enhanced intuition and foresight. These beliefs laid the foundation for Moonstone’s enduring reputation as a stone of insight and emotional balance.
The gemstone’s mystical allure grew during the Victorian era, when it became a popular choice for romantic and sentimental jewelry. It was believed to promote harmony in relationships and was often gifted as a symbol of love and fidelity. This tradition continues today, with Moonstone being a favored gem in engagement rings, pendants, and bracelets that celebrate emotional connection and spiritual alignment.
In modern times, Moonstone is also closely linked to the zodiac sign of Gemini. Known for its duality and adaptability, Gemini finds resonance in Moonstone’s representation of emotional balance and change. June 15th, in particular, aligns with the stone’s themes of renewal and transformation, making it a powerful symbol for those born on this day.
Geological Formation and Sources
Moonstone is a type of feldspar mineral, specifically a potassium-rich feldspar known as orthoclase. It forms in igneous and metamorphic rocks through a process called exsolution, in which different minerals separate within a single crystal lattice. This process creates the distinct layers responsible for Moonstone’s characteristic glow.
The best-quality Moonstone is typically found in India, particularly in the southern states of Tamil Nadu and Andhra Pradesh. These regions produce some of the finest specimens, known for their intense adularescence and clarity. Other notable sources include Brazil, Sri Lanka, and Madagascar, where Moonstone is also mined in various forms, from translucent to milky white.
The color of Moonstone can vary depending on the impurities and mineral composition of the stone. While the most common colors are white with a blue sheen, other varieties include green, gray, and even rare golden or peach-colored Moonstones. The size and clarity of the stone are also factors that influence its value and desirability in jewelry.
Moonstone is relatively abundant in the gemstone market, which makes it more accessible than some other precious stones. However, high-quality specimens with strong adularescence and clean, transparent interiors are highly prized and can command higher prices.
Gemological Properties
Moonstone is a unique gemstone with a range of properties that make it both visually striking and relatively easy to work with in jewelry. Below is a detailed overview of its key gemological characteristics:

| Hardness (Mohs Scale) | 6 to 6.5 |
| Refractive Index | 1.518 to 1.526 |

Moonstone is typically cut into a cabochon to best showcase its adularescence. Faceted cuts are less common but can be used to highlight the stone’s color and clarity. The gem’s relatively low hardness and perfect cleavage require careful handling and setting in jewelry to prevent chipping or breaking.
Symbolism and Metaphysical Beliefs
Moonstone is deeply rooted in metaphysical traditions and is often associated with the moon’s cycles and feminine energy. It is believed to enhance intuition, promote emotional balance, and support spiritual growth. These properties make it a popular stone for meditation, healing, and personal development.
In ancient times, Moonstone was considered a powerful talisman for fertility and was often worn by women seeking to conceive or maintain a healthy pregnancy. It was also believed to bring calmness and protection during travel, especially at night when the moon was full.
Modern metaphysical practices continue to honor Moonstone’s calming and nurturing qualities. It is often used to support those undergoing emotional transitions, such as divorce, loss, or major life changes. The stone is said to help individuals navigate these experiences with grace and resilience.
Moonstone is also connected to the third eye and crown chakras, making it a valuable tool for spiritual awakening and psychic development. It is believed to enhance one’s ability to see beyond the surface of things and access deeper levels of consciousness.
Jewelry and Design
Moonstone’s soft, luminous glow makes it a popular choice for a wide range of jewelry designs. It complements both classic and contemporary styles and pairs well with metals such as silver and gold. In particular, sterling silver is often used in Moonstone jewelry to enhance its ethereal qualities.
Common jewelry pieces that feature Moonstone include pendants, earrings, rings, and bracelets. Each design is crafted to highlight the stone’s unique beauty and symbolism. For example, Moonstone pendants are often set in silver with delicate filigree or minimalist settings that allow the gem to take center stage.
Moonstone is also a popular choice for birthstone jewelry, especially for those born on June 15th. Custom-designed pieces allow individuals to create meaningful and personalized jewelry that reflects their style and connection to the stone.
When designing Moonstone jewelry, it is important to consider the gem’s physical properties. Due to its relatively low hardness and perfect cleavage, Moonstone requires careful handling and appropriate settings to prevent damage. Prong and bezel settings are often preferred to secure the stone and protect it from impact.
Care and Maintenance
Proper care is essential to preserve the beauty and longevity of Moonstone jewelry. Given its relatively low hardness and susceptibility to cleavage, Moonstone requires gentle handling and specific cleaning methods to avoid damage.
To clean Moonstone, it is recommended to use a soft cloth and mild soap and water. Avoid using ultrasonic or steam cleaners, as these can cause the stone to crack or chip. After cleaning, gently pat the stone dry with a soft cloth and store it in a separate compartment to prevent scratches from harder gemstones.
When wearing Moonstone jewelry, it is advisable to avoid exposure to harsh chemicals, extreme temperatures, and physical impact. These can weaken the stone’s structure and dull its luster over time. Removing Moonstone jewelry before swimming, exercising, or engaging in activities that involve contact with abrasive surfaces is also recommended.
For long-term storage, keep Moonstone in a soft pouch or lined jewelry box to protect it from dust and scratches. Regular inspections by a professional jeweler can help ensure that the settings remain secure and that the stone stays in optimal condition.
