June is one of the few months in the birthstone calendar that boasts not one, but three distinct gemstones—pearl, moonstone, and alexandrite. Each of these stones carries its own unique characteristics, history, and symbolism. Together, they form a triad of natural beauty that reflects the diversity and richness of gemology. This article explores the color variations, historical significance, geological properties, and cultural symbolism of these three June birthstones. By delving into the details provided by credible gemological and historical sources, we gain a deeper appreciation for these treasured stones.
A Spectrum of Colors
The June birthstones are distinguished by their wide range of colors, offering an array of choices for jewelry and personal adornment. These colors are not only aesthetically pleasing but also reflect the gemological and cultural properties of each stone.
Pearl: The Timeless Classic
Pearls are the most traditional and widely recognized June birthstone. Unlike most gemstones, which are formed from mineral deposits, pearls are organic gemstones created by living organisms—specifically, mollusks such as oysters and mussels. This unique origin gives pearls a distinct quality and a soft, luminous appearance known as "orient."
Pearls come in a variety of colors, including classic white, cream, pink, silver, black, and even gold. The most common is white, often associated with purity and elegance. However, pearls can also display a range of pastel hues, with pink and silver tones being particularly popular. The color of a pearl is determined by the type of mollusk that produces it, as well as environmental factors such as water composition and temperature.
The luster of pearls is another important characteristic. Known as "orient," this inner glow is caused by the refraction of light through the nacre layers that make up the pearl's surface. The quality of this luster is a key factor in determining a pearl’s value and beauty.
Moonstone: The Enchanting Glow
Moonstone is another June birthstone, known for its ethereal, milky appearance and the subtle sheen it displays. This effect, known as "adularescence," is caused by the diffraction of light through alternating layers of different minerals within the stone—typically orthoclase and albite.
Moonstone is most commonly white or beige, but it can also appear in shades of blue, which are particularly prized. The blue sheen is especially captivating, creating an illusion of movement and depth. This phenomenon is what gives moonstone its name, as it resembles the glow of the moon.
The color variation in moonstone is not only visually appealing but also historically significant. Blue moonstone is considered one of the most valuable varieties, and it is often used in fine jewelry. Other colors, such as peach, gray, and even rainbow hues, are also available, making moonstone a versatile gemstone.
Alexandrite: The Color-Changing Marvel
Alexandrite is the rarest and most recently discovered of the June birthstones. It is known for its extraordinary ability to change color depending on the type of light it is exposed to. In daylight or fluorescent light, alexandrite appears green to bluish-green, while under incandescent light, it shifts to a deep red or purplish-red hue. This color-changing property is due to a phenomenon known as pleochroism, where the stone absorbs and reflects different wavelengths of light depending on the viewing angle.
The most prized alexandrite displays a vivid green in daylight and a rich red in incandescent light. This dramatic shift is what makes alexandrite one of the most sought-after gemstones in the world. It is often described as the "chameleon of gemstones" due to its ability to transform its appearance.
Alexandrite was first discovered in the Ural Mountains of Russia in 1834 and was named after Czar Alexander II. Its rarity and unique properties quickly made it a symbol of prestige and national pride. Today, alexandrite is also found in Brazil, Sri Lanka, and Zimbabwe, but the original Russian deposits remain the most highly valued.
Historical and Cultural Significance
Each of the June birthstones has a rich history and cultural significance that contributes to its enduring appeal.
Pearl: Symbol of Purity and Wealth
Pearls have been revered for centuries for their beauty and rarity. In ancient times, they were considered symbols of purity, wisdom, and the moon. In many cultures, pearls were associated with femininity and grace, making them a popular choice for women’s jewelry.
In Chinese culture, pearls were believed to have healing properties and were used in traditional medicine. They were also associated with the moon and were considered a symbol of longevity. In India, pearls were often used in royal jewelry and were considered a sign of status and power.
The Roman poet Pliny the Elder wrote extensively about pearls, describing them as "the tears of the sea." This poetic interpretation has endured through the centuries and continues to be a popular theme in pearl jewelry.
Moonstone: A Stone of Mysticism
Moonstone has long been associated with mysticism and intuition. In ancient Roman culture, it was believed to be formed from moonbeams, and it was associated with the moon goddess Diana. This connection to the moon gave moonstone a reputation for enhancing intuition and promoting calmness.
In India, moonstone is considered a sacred stone and is often used in Ayurvedic practices. It is believed to balance the body’s energies and promote emotional stability. The stone is also associated with the third eye chakra, which is believed to be the center of intuition and spiritual insight.
The ethereal beauty of moonstone has made it a popular choice in Victorian and Art Nouveau jewelry. During these periods, moonstone was often used in combination with other gemstones, such as diamonds and pearls, to create intricate and elegant designs.
Alexandrite: The Royal Gem
Alexandrite was discovered in Russia during the 19th century and quickly became a symbol of national pride. It was named after Czar Alexander II, who received a gemstone for his 16th birthday. The stone’s color-changing properties were seen as a reflection of the Czar’s military colors—green for the infantry and red for the cavalry.
Alexandrite was also considered a talisman by many Russians, who believed it brought good luck and protected the wearer from danger. This belief was based on the idea that the stone’s color change could serve as a warning—green in daylight and red at night—indicating when it was safe to travel or when danger was near.
Despite its initial association with Russian royalty, alexandrite has become a global symbol of rarity and elegance. It is often used in high-end jewelry and is considered a special gift for those born in June.
Geological Formation and Sources
Understanding the geological formation and sources of the June birthstones provides insight into their rarity and value.
Pearl Formation
Pearls are formed within the soft tissue of mollusks, primarily oysters and mussels. The 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 combination of calcium carbonate and conchiolin—around the irritant. Over time, these layers build up to form a pearl.
Natural pearls are extremely rare, as the conditions required for their formation are highly specific. Most pearls available today are cultured, meaning they are created through human intervention. In the case of cultured pearls, a small piece of mantle tissue from another mollusk is inserted into the host mollusk, which then begins to secrete nacre around it.
The most common types of pearls include Akoya, Tahitian, and South Sea pearls. Akoya pearls are typically white or pink and are produced in Japan and China. Tahitian pearls are known for their dark colors, including black, green, and blue, and are found in French Polynesia. South Sea pearls, which are the largest and most valuable, are produced in Australia and Indonesia and come in white, gold, and silver hues.
Moonstone Formation
Moonstone is a type of feldspar, a group of minerals that make up a significant portion of the Earth’s crust. It is formed through a process known as exsolution, where two different minerals—orthoclase and albite—separate from each other as the rock cools. This separation creates the alternating layers that give moonstone its distinctive sheen.
Moonstone is found in various parts of the world, including India, Sri Lanka, and the United States. The most prized moonstone, with its striking blue sheen, is typically sourced from Sri Lanka. This variety is known for its high quality and is often used in fine jewelry.
Moonstone is relatively soft compared to other gemstones, with a hardness of 6 to 6.5 on the Mohs scale. This makes it more susceptible to scratches and damage, so it requires careful handling and proper care to maintain its luster.
Alexandrite Formation
Alexandrite is a rare variety of the mineral chrysoberyl, which is composed of beryllium and aluminum. Its color-changing properties are due to the presence of trace amounts of chromium, which gives it its green and red hues. The formation of alexandrite requires specific geological conditions, including high temperatures and the presence of beryllium-rich minerals.
The original source of alexandrite was the Ural Mountains of Russia, where it was first discovered in 1834. However, the Russian deposits were nearly depleted by the late 19th century. In the 20th century, alexandrite was discovered in Brazil, followed by Sri Lanka and Zimbabwe. While these new sources have expanded the availability of alexandrite, the Russian material is still considered the most valuable due to its superior color change and clarity.
Alexandrite has a hardness of 8.5 on the Mohs scale, making it relatively durable for everyday wear. However, its rarity and unique properties make it one of the most valuable gemstones in the world.

Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and value of June birthstones. Each of these gemstones has specific care requirements based on its composition and hardness.
Pearl Care
Pearls are relatively soft and require gentle care to maintain their luster and beauty. They should be cleaned with a soft, damp cloth and mild soap, avoiding harsh chemicals or abrasive materials. Pearls should not be exposed to heat, steam, or ultrasonic cleaners, as these can damage the nacre layers and cause the pearls to become dull or discolored.
Pearls should also be stored separately from other gemstones, as they can be scratched by harder materials such as diamonds and sapphires. They should be kept in a soft pouch or lined jewelry box to prevent friction and damage.
Moonstone Care
Moonstone is also relatively soft, with a hardness of 6 to 6.5 on the Mohs scale. It should be cleaned with a soft cloth and mild soap, avoiding ultrasonic cleaners and steam, which can cause the layers within the stone to separate or become damaged. Moonstone should also be stored separately from harder gemstones to prevent scratches.
Moonstone is sensitive to extreme temperatures and should be kept away from heat sources. It is also sensitive to certain chemicals, so it should be removed before exposure to household cleaners or perfumes.
Alexandrite Care
Alexandrite is harder than pearl and moonstone, with a hardness of 8.5 on the Mohs scale, but it is still a delicate gemstone that requires careful handling. It can be cleaned with a soft cloth and mild soap, and it is generally safe to use ultrasonic and steam cleaners. However, it is always a good idea to consult with a professional jeweler before using any cleaning methods.
