June is one of the few months in the calendar year that boasts not one, but three official birthstones. These gemstones—pearl, moonstone, and alexandrite—each carry a unique blend of history, symbolism, and natural beauty. While pearls are the most commonly recognized among the three, moonstone and alexandrite offer equally captivating qualities that have made them cherished additions to the June birthstone list. Together, they reflect the month’s themes of balance, rejuvenation, and celebration. This article delves into the rich histories, gemological properties, cultural significance, and modern relevance of these three remarkable stones.
A Historical Overview of June Birthstones
The tradition of assigning birthstones to each month dates back centuries, with roots in ancient cultures that attributed mystical powers and symbolic meanings to specific gemstones. While the exact origins of the June birthstone list are difficult to pinpoint, the inclusion of pearl, moonstone, and alexandrite reflects a long-standing appreciation for their natural beauty and perceived spiritual properties.
Pearl has been a symbol of purity, innocence, and wisdom in many cultures, particularly in the East. Ancient Romans and Greeks also valued pearls, often associating them with the moon and the goddess Juno, after whom the month of June was named. Moonstone, with its ethereal shimmer, was revered by the Romans as a sacred stone tied to the moon and lunar deities. It was believed to enhance intuition and provide a deeper connection to the spiritual world.
Alexandrite, the most modern of the June birthstones, was discovered in the 19th century in the Ural Mountains of Russia. Named in honor of Czar Alexander II, whose birthday coincided with the stone's discovery, alexandrite quickly became a prized gem due to its rare and dramatic color-changing ability. Initially a source of great scarcity, alexandrite was nearly lost to history when the Urals’ deposits were exhausted. Fortunately, new sources in Brazil and other regions later made it more accessible, allowing it to become a popular birthstone option.
The inclusion of multiple stones for June reflects the evolving nature of birthstone traditions. While the earliest records, such as the 1870 pamphlet by Tiffany & Co., only listed pearl, the addition of moonstone and alexandrite in the 20th century broadened the options for June-born individuals. Today, the three stones are celebrated for their distinct characteristics and the unique stories they carry.
Geological Formation and Sources
Each of the three June birthstones has its own geological origin and source locations, contributing to their rarity and value.
Pearl
Pearls are not minerals but organic gemstones formed within the soft tissue of living shelled mollusks. They are composed primarily of calcium carbonate in the form of the mineral aragonite, bound by an organic protein called conchiolin. The process of pearl formation begins when an irritant, such as a grain of sand, enters the mollusk’s mantle. To protect itself, the mollusk coats the irritant with layers of nacre, a substance secreted by the mantle. Over time, these layers build up to form a pearl.
Pearls can be found in both freshwater and saltwater environments. The most valuable pearls, including the coveted South Sea and Tahitian pearls, are produced in saltwater oysters, while freshwater pearls are cultivated in mussels and are generally less expensive. China is the world's largest producer of freshwater pearls, while Australia and Indonesia are known for their high-quality South Sea pearls.
Moonstone
Moonstone is a type of feldspar mineral, specifically a variety of orthoclase or albite feldspar. Its signature shimmer, known as adularescence, is caused by the reflection of light from layers of alternating feldspar minerals within the stone. This phenomenon gives moonstone its characteristic silvery glow, reminiscent of moonlight.
Moonstone is found in various parts of the world, including Sri Lanka, India, Brazil, and the United States. Sri Lankan moonstones are particularly prized for their translucent blue sheen, while Indian moonstones can vary in color from beige to green or brown. The stone's widespread presence in the Earth's crust makes it relatively abundant, yet its unique optical properties ensure its continued appeal in jewelry and decorative arts.
Alexandrite
Alexandrite is a rare variety of the mineral chrysoberyl, with a chemical composition of BeAl₂O₄. Its color-changing property, known as pleochroism, is due to the presence of trace amounts of chromium. By day, alexandrite appears green or greenish-blue, while under incandescent light, it shifts to a deep red or purplish hue.
The first alexandrite deposits were found in the Ural Mountains of Russia in the 19th century. However, as these mines became depleted, new sources were discovered in Brazil, Madagascar, and Myanmar. Brazilian alexandrite is particularly notable for its vivid color change and is often considered the finest quality. Due to its rarity and desirable properties, alexandrite remains a highly valued gemstone in the world of fine jewelry.

Care and Cleaning
Each of the three June birthstones requires specific care to maintain its beauty and longevity.
Pearl
Pearls are among the most delicate of all gemstones due to their organic composition. They are sensitive to harsh chemicals, abrasion, and changes in humidity and temperature. To care for pearls:
- Avoid Exposure to Chemicals: Remove pearl jewelry before applying lotions, perfumes, or cleaning products.
- Store Properly: Store pearls separately in a soft cloth or jewelry box to prevent scratches.
- Clean Gently: Wipe pearls with a soft, damp cloth to remove dust and oils. Avoid using ultrasonic or steam cleaners, as these can damage the nacre.
Moonstone
Moonstone is more durable than pearls but still requires careful handling. It is sensitive to high heat and acidic substances. To care for moonstone:
- Avoid Harsh Chemicals: Remove moonstone jewelry before using household cleaners or perfumes.
- Store in a Cool, Dry Place: Moonstone should be stored away from direct sunlight and heat to prevent discoloration.
- Clean with Mild Soap and Water: Gently clean moonstone with a soft cloth and warm, soapy water. Avoid using ultrasonic cleaners, as they may cause damage.
Alexandrite
Alexandrite is a relatively durable gemstone but still requires proper care to maintain its brilliance. To care for alexandrite:
- Avoid Exposure to Heat and Chemicals: Alexandrite can be sensitive to high heat and strong acids or bases.
- Store Separately: To prevent scratches, store alexandrite away from harder gemstones.
- Clean with a Soft Cloth and Warm Water: A gentle cleaning with a soft cloth and warm, soapy water will help keep alexandrite looking its best. Avoid using steam or ultrasonic cleaners unless recommended by a professional.
