June is a month of celebration and transformation, symbolizing the beginning of summer and the blossoming of life. In the world of gemstones, June is also unique in that it is one of only three months (along with August and December) to have three official birthstones: pearl, moonstone, and alexandrite. These gemstones are not only visually distinct but also carry rich histories, cultural significance, and symbolic meanings. For those born on June 29th, the choice of birthstone can reflect a range of preferences—whether for the classic elegance of pearl, the mystical allure of moonstone, or the mesmerizing color-changing property of alexandrite.
This article explores the three June birthstones in depth, drawing on historical accounts, gemological properties, and cultural lore, as outlined in authoritative sources. Whether you are a gemstone enthusiast, a jewelry buyer, or a student of gemology, this guide will provide a comprehensive understanding of the June birthstones and their enduring appeal.
History and Lore
The concept of birthstones dates back centuries, with roots in religious, cultural, and astrological traditions. The earliest known references to birthstones are found in the biblical Book of Exodus, which mentions the twelve stones on the high priest Aaron’s breastplate. Over time, these stones were associated with the twelve months of the year, a practice that evolved further in the Middle Ages and Renaissance. By the 19th century, formalized lists of birthstones began to emerge, with variations between countries and cultures.
June, in particular, has a fascinating historical background. Known in ancient Rome as Junius or Lunius, the month was named after Juno, the goddess of marriage, or the Latin iuniores, meaning “youth.” It was a time of celebration and renewal, marked by festivals such as the Rosalia (festival of roses), Vestalia (honoring the goddess of the hearth, Vesta), and the summer solstice—the first day of summer. These traditions are still reflected in modern June holidays such as Father’s Day, LGBTQ+ Pride Month, and International Children’s Day.
The three June birthstones—pearl, moonstone, and alexandrite—each have their own unique historical associations. Pearls, for example, have long been symbols of purity and elegance. Ancient cultures, including those of the Middle East and China, believed that pearls formed from dew or divine tears. Christopher Columbus and his contemporaries thought that mollusks created pearls from dew drops, a belief that persisted for centuries.
Moonstone, on the other hand, has a more mystical reputation. The Roman historian Pliny the Elder gave the gemstone its name due to its shimmering appearance, which he likened to the changing phases of the moon. In Greek and Roman mythology, moonstone was associated with lunar deities, while in Hindu mythology, it was said to be made of solidified moonbeams. Known as “The Traveller’s Stone,” moonstone was historically used as a protective charm for night travelers.
Alexandrite is the most modern of the three June birthstones. Discovered in the 19th century in the Ural Mountains of Russia, alexandrite is named after Tsar Alexander II. Its most notable feature is its color-changing property, appearing green in daylight and red in incandescent light. This phenomenon, known as pleochroism, made alexandrite a symbol of transformation and duality—qualities that resonate with the month of June.
Geological Formation and Sources
Each of the June birthstones has a distinct geological origin, mineral composition, and mining location.
Pearl
Pearls are organic gemstones formed within the soft tissue of living shelled mollusks, primarily oysters and mussels. The formation process begins when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. To protect itself, the mollusk secretes layers of nacre, a substance made of calcium carbonate, water, and conchiolin. Over time, these layers build up to form a pearl.
There are two main types of pearls: freshwater pearls and saltwater pearls. Freshwater pearls are typically found in rivers and lakes and are produced by mussels. They can come in a wide range of shapes and colors. Saltwater pearls, such as Akoya pearls from Japan, South Sea pearls from Australia and Indonesia, and Tahitian pearls from French Polynesia, are known for their round shape and lustrous appearance.
Moonstone
Moonstone is a variety of the mineral feldspar, specifically orthoclase feldspar. It is known for its adularescence, an optical phenomenon where a milky, glowing light appears to move across the surface of the stone. This effect is caused by the interference of light within the stone’s layers of different minerals.
Moonstone is typically found in granitic rocks and pegmatites, and it is mined in various parts of the world, including India, Sri Lanka, Brazil, and the United States. The most valuable moonstones exhibit a blue sheen, particularly when viewed against a white background. These stones are often used in jewelry and are prized for their ethereal beauty.
Alexandrite
Alexandrite is a variety of the mineral chrysoberyl, a rare and durable gemstone. Its most distinctive feature is its color-changing property, which is caused by the presence of chromium as a trace element. In daylight or fluorescent light, alexandrite appears green or greenish-blue, while in incandescent light, it shifts to a deep red or purplish hue.
The original source of alexandrite was the Ural Mountains in Russia, where it was discovered in the early 19th century. Today, alexandrite is also found in Brazil, India, Madagascar, and Sri Lanka. Due to its rarity and unique properties, alexandrite is one of the most sought-after gemstones in the world.
Gemological Properties
Understanding the gemological properties of each birthstone is essential for appreciating their beauty and durability.
| Gemstone | Color | Hardness (Mohs Scale) | Composition | Luster | Transparency |
|---|---|---|---|---|---|
| Pearl | White, cream, pink, black | 2.5–4.5 | Calcium carbonate, conchiolin | Waxy | Opaque |
| Moonstone | White, gray, blue, pink | 6–6.5 | Orthoclase feldspar | Vitreous | Translucent |
| Alexandrite | Green in daylight, red in incandescent light | 8.5–9 | Beryllium aluminum oxide (Chrysoberyl) | Vitreous | Transparent |
Pearl
Pearls are relatively soft, with a hardness of 2.5 to 4.5 on the Mohs scale, making them susceptible to scratches and damage. They are composed mainly of calcium carbonate, and their luster is waxy rather than glassy. Pearls are opaque, meaning that they do not allow light to pass through them. Because of their organic origin and softness, pearls require careful handling and cleaning.
Moonstone
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it more durable than pearl but still relatively soft compared to other gemstones. It is composed of orthoclase feldspar, a type of silicate mineral. Moonstone has a vitreous (glassy) luster and is translucent, meaning that some light can pass through it. Its adularescence is one of its most distinctive features, creating a glowing effect that is best seen in well-cut stones.
Alexandrite
Alexandrite is one of the hardest of the June birthstones, with a hardness of 8.5 to 9 on the Mohs scale. It is composed of beryllium aluminum oxide, also known as chrysoberyl. Alexandrite has a vitreous luster and is transparent, allowing light to pass through it. Its color-changing property makes it a truly unique gemstone, and it is highly valued for both its beauty and rarity.
Symbolism and Metaphysical Beliefs
The June birthstones are not only valued for their beauty but also for their symbolic and metaphysical significance.
Pearl
In many cultures, pearls have long been associated with purity, wisdom, and inner strength. In ancient times, they were believed to be formed from the teardrops of angels or the brain of a dragon. In modern times, pearls are often associated with femininity, elegance, and sophistication. They are also seen as symbols of love and loyalty, making them a popular choice for wedding jewelry and anniversary gifts.
In some traditions, pearls are believed to enhance emotional balance and calmness, helping the wearer to navigate life’s challenges with grace. They are also associated with prosperity and good fortune, and in some cultures, they are believed to bring longevity and protection.

Care and Cleaning
Proper care and cleaning are essential for preserving the beauty and longevity of June birthstones. Each gemstone has specific care requirements based on its hardness, luster, and sensitivity to chemicals and heat.
Pearl
Pearls are among the softest of the June birthstones and require gentle care. They should be cleaned with a soft, damp cloth and avoided exposure to harsh chemicals, perfumes, and lotions, as these can dull their luster. Pearls should not be subjected to extreme heat or prolonged exposure to sunlight, as this can cause them to dry out and lose their shine.
To preserve the shape and integrity of pearl strands, they should be stored separately from other jewelry to avoid scratches. It is also recommended to string pearls only when needed, as constant handling can weaken the thread over time.
Moonstone
Moonstone is more durable than pearl but still requires careful handling. It should be cleaned with a soft cloth and mild soap, and avoided exposure to harsh chemicals or abrasive cleaners. Moonstone is sensitive to heat and prolonged sunlight, which can cause it to fade or become cloudy.
To maintain the adularescence effect, moonstone should be stored in a cool, dark place. It is also advisable to remove moonstone jewelry before swimming, showering, or applying cosmetics, as these activities can expose the stone to moisture and chemicals that may affect its appearance.
Alexandrite
Alexandrite is the hardest of the June birthstones and is relatively durable, but it should still be handled with care. It is sensitive to heat and sudden temperature changes, which can cause it to fracture or lose its color-changing properties.
To clean alexandrite, use a soft cloth and a mild, pH-neutral cleaner. Avoid using ammonia or bleach, as these can damage the stone. Alexandrite should also be stored separately from other jewelry to prevent scratches, and it should be removed before engaging in physical activities to avoid impact damage.
