For those born on June 16, the birthstone selection includes two of the most captivating gemstones: alexandrite and moonstone. June is one of only three months that proudly feature multiple birthstones, and this unique tradition allows June 16 celebrants to choose between a rare, color-changing marvel and a glowing, ethereal stone tied to lunar energy. While alexandrite is often considered the more modern and luxurious of the two, moonstone holds a rich historical and spiritual significance.
This article explores the gemological properties, cultural symbolism, and care requirements of both alexandrite and moonstone—offering a comprehensive guide for enthusiasts, jewelry buyers, and gemologists. We will examine their origins, uses, and the reasons behind their enduring appeal.
The Historical and Cultural Significance of June 16 Birthstones
June 16 falls within the second half of the month, a period traditionally associated with alexandrite and moonstone. These gemstones carry deep historical roots and symbolic meanings, making them ideal for those born on this date.
Alexandrite: A Modern Marvel of Transformation
Alexandrite is a relatively recent addition to the birthstone tradition, first discovered in the 19th century. It was named in honor of the Russian Tsar Alexander II, and its rarity and unique color-changing properties quickly made it a prized gemstone. Alexandrite symbolizes transformation, adaptability, and spiritual growth. Its ability to shift color from green in daylight to red in incandescent light is not only visually stunning but also metaphorical, representing the balance between different aspects of life.
Moonstone: The Stone of Emotional Balance
Moonstone, on the other hand, is one of the older June birthstones, with a history that spans thousands of years. Ancient cultures believed moonstone to be a gift from the moon goddess, imbued with the power to bring emotional harmony and intuition. The stone’s glowing appearance, known as adularescence, is due to the way light interacts with its internal structure. This ethereal shimmer makes moonstone a popular choice for those seeking a connection to lunar energy and emotional stability.
Together, alexandrite and moonstone represent a powerful combination of transformation and balance—perfect for those born on June 16, who may find themselves navigating both inner and external changes in their lives.
The Geological Formation and Sources of June 16 Birthstones
To truly understand the value and appeal of alexandrite and moonstone, it is essential to explore their geological origins and the locations where they are found.
Alexandrite: A Rare and Elusive Gem
Alexandrite is a chrysoberyl variety with the chemical formula BeAl2O4. It is known for its extraordinary ability to change color, a phenomenon caused by the presence of chromium impurities. This unique property makes alexandrite one of the most sought-after gemstones in the world.
The most famous source of alexandrite is Brazil, particularly in the state of Minas Gerais, where high-quality specimens are still found today. Other notable sources include India, Sri Lanka, and Myanmar, although these deposits tend to yield smaller or less intense color-changing stones.
Alexandrite is a hard gemstone, with a Mohs hardness of 8.5, making it durable enough for daily wear. However, due to its rarity and the difficulty of finding high-quality color-changing specimens, alexandrite is considered one of the most valuable birthstones.
Moonstone: A Captivating Product of Nature
Moonstone is a type of feldspar, a mineral group that includes many common and rare varieties. The most prized moonstone for jewelry is adularia, which exhibits the characteristic adularescence—a soft, glowing light that appears to float across the surface of the stone.
Moonstone is found in various parts of the world, including India, Sri Lanka, Brazil, and the United States. India and Sri Lanka are particularly well known for producing high-quality moonstone with strong adularescence. These stones are often used in jewelry, especially in bohemian and modern designs.
Moonstone has a Mohs hardness of 6 to 6.5, which means it is relatively soft compared to other gemstones. As a result, it is best suited for jewelry that is not subject to heavy wear, such as pendants and earrings.
The Gemological Properties of June 16 Birthstones
Understanding the gemological properties of alexandrite and moonstone provides insight into their beauty, durability, and care requirements.
Alexandrite
- Chemical Formula: BeAl2O4
- Hardness (Mohs Scale): 8.5
- Color Change: Green in daylight to red in incandescent light
- Luster: Vitreous
- Refractive Index: 1.74–1.78
- Specific Gravity: 3.70–4.00
- Cleavage: None
- Transparency: Transparent to translucent
- Common Cuts: Oval, cushion, emerald
- Treatment: Some alexandrite is heat-treated to enhance color.
Alexandrite is a gemstone of rare beauty and scientific intrigue. Its color-changing ability is due to the way light is absorbed and reflected by the chromium in its structure. This makes each alexandrite unique, with variations in the intensity and range of its color shift.
Moonstone
- Chemical Formula: KAlSi3O8 (adularia)
- Hardness (Mohs Scale): 6–6.5
- Color: White, with flashes of blue, green, or yellow
- Luster: Vitreous to pearly
- Refractive Index: 1.52–1.53
- Specific Gravity: 2.58–2.62
- Cleavage: Perfect in one direction
- Transparency: Translucent to transparent
- Common Cuts: Cabochon, oval, round
- Treatment: Heat treatment is sometimes used to enhance the color or adularescence.
Moonstone’s adularescence is one of its most distinctive features. This optical effect is caused by the intergrowth of two feldspar minerals—orthoclase and albite—which scatter light in a way that creates the illusion of a floating glow. The best moonstone for jewelry is typically cut as a cabochon, a smooth, rounded shape that enhances the stone’s glow.
The Symbolism and Metaphysical Beliefs of June 16 Birthstones
Both alexandrite and moonstone carry deep symbolic meanings that have been recognized across cultures and centuries. These gemstones are not only admired for their beauty but also for their perceived spiritual and emotional properties.
