May and June, two months filled with renewal and light, each hold a unique collection of gemstones that reflect the natural world and human fascination with beauty and symbolism. While May is represented by a single gemstone, the emerald, June is distinguished by a trio of stones: the pearl, moonstone, and alexandrite. These gemstones, each with distinct origins, properties, and cultural meanings, have captivated jewelers, collectors, and historians for centuries. This article explores the geological, historical, and metaphysical aspects of these birthstones, offering a comprehensive guide to their significance and care.
History and Lore
May Birthstone: Emerald
Emerald is a gemstone with deep historical roots and an enduring legacy. As the birthstone for May, it symbolizes renewal, growth, and vitality—apt themes for a month that heralds spring. The emerald has been cherished since ancient times, with records of its use dating back to the Egyptians, Greeks, and Romans. Cleopatra was particularly known for her love of emeralds, often adorning herself with them and commissioning jewelry that showcased the gemstone's vivid green hue.
Emerald’s allure stems from its rich green color, a result of trace amounts of chromium or vanadium in its beryl structure. The gemstone was historically believed to have protective and healing properties. In ancient cultures, it was thought to ward off evil, enhance vision, and promote love and patience. These beliefs have carried through time, and in modern times, emerald is associated with wisdom, balance, and emotional well-being.
Emerald’s journey from ancient times to its current status as a celebrated birthstone reflects its enduring beauty and cultural significance. Its presence in royal collections and modern jewelry alike underscores its timeless appeal.
June Birthstones: Pearl, Moonstone, and Alexandrite
June is unique among the months in the birthstone calendar, as it is associated with not one, but three gemstones: pearl, moonstone, and alexandrite. Each of these stones has its own distinct history, symbolism, and cultural significance.
Pearl
Pearl is the traditional birthstone for June and is one of the oldest known gemstones. Unlike most gemstones, which are formed through geological processes, pearls are organic, formed within the soft tissue of living mollusks such as oysters and mussels. The formation of a pearl occurs when an irritant, such as a grain of sand, enters the mollusk’s shell. In response, the mollusk secretes layers of nacre, a lustrous substance composed of calcium carbonate and conchiolin, around the irritant, gradually forming a pearl.
Pearls have been treasured for thousands of years and have appeared in various forms of art, jewelry, and mythology. Ancient Greeks believed that pearls were formed from the tears of the gods, while in China, pearls were associated with immortality. During the Renaissance, pearls became a symbol of purity and were often used in royal and religious settings. Today, pearls are associated with wisdom, serenity, and emotional balance.
Moonstone
Moonstone, another of June’s birthstones, is a gemstone known for its ethereal glow. Its name comes from its opalescent sheen, which resembles the light of the moon. The gemstone is a type of feldspar and is best known for its adularescence—a phenomenon in which light appears to shimmer or float across the surface of the stone.
Moonstone has a rich history in various cultures. In India, it is considered a sacred stone and is often worn by men to balance their emotions and attract love. In European folklore, moonstone was believed to bring good luck and was worn by women to enhance fertility and protect them during childbirth. In modern times, moonstone is associated with intuition, emotional balance, and the divine feminine.
Alexandrite
Alexandrite is the rarest and most modern of June’s birthstones. Discovered in 1830 in Russia, it was named after Tsar Alexander II in his honor. The gemstone is known for its remarkable ability to change color under different lighting conditions. In daylight, it appears green due to the presence of chromium, while under incandescent light, it shifts to a reddish or purplish hue. This color-changing phenomenon has made alexandrite a symbol of transformation and adaptability.
Alexandrite was quickly embraced as a symbol of good fortune and was highly prized by Russian aristocracy. Its rarity and unique properties have made it a coveted gemstone in modern jewelry. Today, alexandrite is associated with balance, transformation, and spiritual growth.
Geological Formation and Sources
Emerald
Emerald is a variety of the mineral beryl, with a chemical composition of Be₃Al₂(SiO₃)₆. It has a hardness of 7.5–8 on the Mohs scale, which makes it relatively durable but still susceptible to damage from hard knocks or high temperatures. Emeralds are typically found in metamorphic rocks, particularly in areas with hydrothermal activity. The most significant sources of emeralds are Colombia, Brazil, and Zambia.
Colombian emeralds are the most famous and are often considered the finest in the world. The Muzo and Chivor mines in Colombia are particularly renowned for producing high-quality emeralds with a rich, pure green color. Brazilian emeralds are also highly valued, with the state of Minas Gerais being a major source. Zambian emeralds are known for their deep green color and are often larger in size than their Colombian counterparts.
Emeralds are often found with inclusions, which are natural imperfections that can affect their clarity and value. These inclusions are often referred to as “gardens” and are considered a hallmark of authenticity. The presence of inclusions can also indicate the origin of the gemstone, as different regions produce emeralds with distinct inclusion patterns.
Pearl
Pearls are formed in the soft tissue of living mollusks, primarily oysters and mussels. The process begins when an irritant, such as a grain of sand, enters the mollusk’s shell. In response, the mollusk secretes layers of nacre, a substance composed of calcium carbonate and conchiolin, around the irritant. Over time, these layers build up to form a pearl.
There are three main types of pearls: natural pearls, cultured pearls, and imitation pearls. Natural pearls are rare and form without human intervention. Cultured pearls are created with the help of humans, who insert a “seed” into the mollusk to stimulate the formation of a pearl. Imitation pearls are man-made and are typically made of glass, plastic, or other materials that mimic the appearance of real pearls.
Cultured pearls are the most common type found in today’s jewelry market. They are produced in countries such as China, Japan, and the United States. The quality and appearance of pearls depend on factors such as the type of mollusk, the water in which they are formed, and the time it takes for the pearl to develop.
Moonstone
Moonstone is a type of feldspar, with a chemical composition that varies depending on its specific type. The most well-known type of moonstone is adularia, which is a potassium aluminum silicate. Moonstone has a hardness of 6–6.5 on the Mohs scale, which makes it relatively soft and prone to damage from hard knocks or abrasive surfaces.
Moonstone is typically found in metamorphic and igneous rocks, particularly in areas with granite deposits. The most significant sources of moonstone are India, Sri Lanka, and the United States. Indian moonstone is particularly prized for its strong adularescence and is often used in traditional Indian jewelry. Sri Lankan moonstone is known for its clarity and is often used in high-quality jewelry. American moonstone is found in states such as North Carolina and is known for its blue sheen.
Moonstone is often found with inclusions, which can affect its clarity and value. These inclusions are typically not as visible as those in emeralds and are often considered a natural part of the gemstone’s character. The presence of inclusions can also help identify the origin of the moonstone.
Alexandrite
Alexandrite is a variety of the mineral chrysoberyl, with a chemical composition of BeAl₂O₄. It has a hardness of 8.5 on the Mohs scale, which makes it one of the harder gemstones. Alexandrite is known for its unique ability to change color under different lighting conditions. In daylight, it appears green due to the presence of chromium, while under incandescent light, it shifts to a reddish or purplish hue.
Alexandrite is typically found in metamorphic rocks, particularly in areas with high chromium content. The most significant sources of alexandrite are Brazil, India, and Russia. Brazilian alexandrite is the most common and is known for its strong color change. Indian alexandrite is often of lower quality and is typically heat-treated to enhance its color. Russian alexandrite is the rarest and is known for its exceptional color change and clarity.
Alexandrite is often found with inclusions, which can affect its clarity and value. These inclusions are typically not as visible as those in emeralds and are often considered a natural part of the gemstone’s character. The presence of inclusions can also help identify the origin of the alexandrite.
Gemological Properties
Emerald
Emerald is a gemstone with a rich green color that ranges from slightly yellowish green to pure green to slightly bluish green.

These treatments are generally accepted in the gem trade and are not considered to devalue the gemstone.
Emeralds are typically evaluated based on their color, clarity, cut, and carat weight. The most valuable emeralds are those with a rich green color, high clarity, and a well-proportioned cut. Larger emeralds are also more valuable, as high-quality large emeralds are rare.
Pearl
Pearls come in a wide range of colors, including white, cream, pink, and black. The most common type of pearl is the white pearl, which is often associated with purity and innocence. The color of a pearl depends on the type of mollusk, the water in which it is formed, and the presence of trace elements.
Pearls are evaluated based on their luster, surface quality, shape, and size. The most valuable pearls are those with a high luster, a smooth surface, a round shape, and a large size. Cultured pearls are generally more affordable than natural pearls and are often used in everyday jewelry.
Pearls are also known for their softness and are relatively easy to damage. They should be handled with care and stored in a soft cloth to prevent scratching. Pearls should not be exposed to harsh chemicals, as this can dull their luster and damage their surface.
