June is one of the few months in the birthstone tradition that proudly boasts three official gemstones: Pearl, Moonstone, and Alexandrite. This unique triad reflects the evolving nature of birthstone traditions over centuries and the desire to offer a broader range of options to suit different tastes, budgets, and symbolic meanings. Each of these gems carries its own distinct history, scientific properties, and cultural significance, making them not only beautiful but deeply meaningful choices for June-born individuals or those seeking a meaningful gift.
This article explores the gemological characteristics, historical background, symbolism, and practical care of each of June's birthstones, drawing exclusively from authoritative and well-documented sources.
A Historical and Cultural Overview
The concept of birthstones dates back to ancient times, with early references found in biblical texts such as the Breastplate of Aaron in Exodus. However, the modern birthstone list was largely standardized in the early 20th century by the American National Retail Jewelers Association (now Jewelers of America). Initially, June was associated with only one gemstone—the pearl—due to its longstanding cultural and symbolic significance. As time passed and gemstone availability and popularity changed, moonstone and alexandrite were added to the June list in the 20th century to provide more options and reflect the growing appreciation for these stones.
Each of these gemstones has a rich history and distinct cultural associations:
- Pearl has been revered for millennia across various civilizations for its natural beauty and associations with purity and wisdom.
- Moonstone is known for its ethereal glow and is often linked to intuition, love, and new beginnings.
- Alexandrite is a relatively modern addition, celebrated for its rare and dramatic color-changing properties, making it a symbol of transformation and love.
Understanding these stones requires a look into their geological origins, gemological properties, and the symbolic meanings attributed to them across different cultures.
The Three June Birthstones
Pearl: The Classic Gem of June
Historical Significance
Pearls have been cherished since ancient times. As early as 2300 BC in ancient China, freshwater pearls were valued by royalty and used in rituals and as symbols of status. Chinese culture associated pearls with purity and honesty, while in India, they were connected to good health and fertility. In the Middle East, pearls were believed to be teardrops from heaven, and in ancient Rome, they became a symbol of power and wealth. In fact, Julius Caesar is said to have restricted the wearing of pearls to the ruling class, underlining their status as a symbol of privilege.
Formation and Sources
Pearls are formed naturally within mollusks such as oysters, clams, and mussels. The process begins when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk coats the irritant with nacre, a substance composed of conchiolin and aragonite. Over time, this coating builds up to form a pearl. Unlike most gemstones, pearls are not mined from the Earth but are cultivated or found in nature within living organisms.
Pearls come in a variety of colors including white, pink, black, and blue, depending on the species of mollusk and the environment in which they are formed. Notably, freshwater pearls are produced by mussels and are more common than saltwater pearls, which are formed in oysters and are typically larger and more valuable.
Symbolism and Meaning
Pearls are often associated with purity, loyalty, and wisdom. In many cultures, they are seen as symbols of inner truth and integrity, and they are frequently given as gifts for births, anniversaries, and weddings. The 20th wedding anniversary is traditionally marked by the gift of pearls, further reinforcing their role in celebrating enduring relationships.
Gemological Properties
- Hardness: 2.5 to 4.5 on the Mohs scale
- Composition: Calcium carbonate (CaCO₃) with conchiolin
- Luster: Pearly luster, especially in saltwater pearls
- Transparency: Varies from translucent to opaque
- Color: White, pink, black, blue, gold, and combinations
- Formation: Formed in mollusks such as oysters, clams, and mussels
Moonstone: The Mystical Glow of June
Historical and Cultural Significance
Moonstone has long been associated with moonlight and lunar energy, and it is often used in jewelry and spiritual practices. In European traditions, moonstone is seen as a stone of intuition and psychic awareness, while in Indian culture, it is believed to enhance love and new beginnings. It is also linked to fertility and emotional balance, and it has been used historically in wedding rings and gifts as a symbol of love and harmony.
Despite its ethereal appearance, moonstone is not considered a precious gemstone in the traditional sense. It is not as hard or durable as diamonds, rubies, or sapphires, and its value depends largely on the quality of its adularescence—the shimmering effect caused by the refraction of light through layers of feldspar and mica.
Formation and Sources
Moonstone is a type of feldspar mineral, specifically a variety of orthoclase or albite. It is formed in igneous and metamorphic rocks, and it is known for its unique optical phenomenon called adularescence, where it appears to shimmer or glow when light is reflected through its layers.
Moonstone is found in various parts of the world, including India, Sri Lanka, Brazil, and the United States. The best-quality moonstones with strong adularescence are often sourced from Sri Lanka and India, where they have been historically valued for their beauty and mystical properties.
Symbolism and Meaning
Moonstone is considered a stone of intuition and emotional balance, and it is often used in spiritual practices to enhance psychic abilities and inner clarity. It is also associated with love, marriage, and fertility, making it a popular choice for wedding rings and anniversary gifts. In some traditions, it is believed to offer protection and support during times of change or transition, reinforcing its role as a stone of new beginnings.
Gemological Properties
- Hardness: 6 to 6.5 on the Mohs scale
- Composition: Feldspar (orthoclase and albite)
- Luster: Vitreous to pearly
- Color: White, yellow, orange, peach, pink, and light blue
- Optical Phenomenon: Adularescence (a shimmering, ghostly light)
- Formation: Formed in igneous and metamorphic rocks
Alexandrite: The Color-Changing Gem of June
Historical Significance
Alexandrite is the most recent addition to the June birthstone list, having been officially recognized in the 1950s. It is known for its rare and dramatic color-changing property, which has made it a symbol of love, transformation, and mystery. The gemstone was discovered in Russia in the 19th century, and it was named after Czar Alexander II due to its discovery in his reign.
Alexandrite’s most notable feature is its pleochroism, or the ability to change color depending on the light source. Under sunlight or fluorescent light, it appears green or bluish-green, while under incandescent light, it shifts to red or purplish-red. This effect has earned it the poetic description: “Emerald by day, ruby by night.”
Formation and Sources
Alexandrite is a rare variety of chrysoberyl, a mineral that is known for its hardness and durability. The color change in alexandrite is caused by the presence of chromium and vanadium in the crystal structure, which alters the way light is absorbed and reflected.
Natural alexandrite is rare and highly valued, and it is found in very few locations worldwide, including Brazil, India, and Madagascar. Due to its rarity and high cost, synthetic alexandrite is sometimes used as a more affordable alternative. However, natural alexandrite remains the most desirable and valuable.
Symbolism and Meaning
Alexandrite is often associated with love, transformation, and adaptability. Its color-changing property is seen as a metaphor for change and growth, and it is often given as a gift for birthdays, anniversaries, and special occasions. In some cultures, it is believed to enhance emotional stability and promote inner strength, making it a stone of resilience and balance.
Gemological Properties
- Hardness: 8.5 on the Mohs scale
- Composition: Chrysoberyl (BeAl₂O₄) with traces of chromium and vanadium
- Color Change: Green to red depending on light source
- Luster: Vitreous
- Formation: Formed in granite and metamorphic rocks
- Optical Phenomenon: Pleochroism (color change)

Care and Maintenance
Each of June’s birthstones requires specific care due to their distinct hardness and sensitivity to environmental factors:
Pearl: Being one of the softest gemstones, pearls are sensitive to acids, heat, and abrasion. They should be stored separately from other jewelry to avoid scratches and cleaned with a soft, damp cloth. Avoid exposure to perfumes, lotions, and harsh chemicals.
Moonstone: While slightly harder than pearls, moonstone is still relatively soft and can be damaged by harsh cleaning methods. It should be stored in a soft pouch and cleaned with warm water and a mild soap, avoiding ultrasonic or steam cleaners.
Alexandrite: Being a hard and durable gemstone, alexandrite is less sensitive and can be cleaned with standard jewelry cleaning methods. However, it should still be stored separately to prevent scratches and exposed to mild detergents and warm water for cleaning.
Conclusion
June’s three birthstones—pearl, moonstone, and alexandrite—offer a rich tapestry of beauty, history, and symbolism. Each stone reflects the evolution of gemstone traditions, from the natural elegance of pearls to the mystical glow of moonstone and the rare color-changing magic of alexandrite. Whether chosen for personal significance, aesthetic appeal, or spiritual connection, these gemstones provide a versatile and meaningful option for June-born individuals or those seeking a sentimental gift.
Understanding the scientific properties, cultural significance, and care requirements of these stones allows for informed appreciation and responsible ownership.
