For those born on June 21, the birthstone is a symbol of elegance, wisdom, and transformation. While traditionally associated with the pearl, the June 21 birthstone can also include the rare and enigmatic Alexandrite. These two gemstones—each with distinct origins, properties, and symbolism—share a common role in celebrating the unique character of those born on this day. This article explores the history, geological formation, gemological properties, cultural significance, and jewelry applications of the June 21 birthstone, offering a comprehensive understanding of its enduring appeal.
Introduction
June 21 marks the summer solstice in the Northern Hemisphere and is often considered a day of renewal and transition. It is also the day when the June 21 birthstone takes center stage. Unlike many gemstones, which are formed deep within the Earth’s crust, the pearl is unique in that it is created within the soft tissues of living mollusks, primarily oysters and mussels. This organic origin gives pearls their distinctive luster and symbolic associations with purity and wisdom. The second gemstone linked to June 21, Alexandrite, is one of the rarest and most fascinating gemstones in the world, known for its ability to change color depending on the type of light in which it is viewed.
Together, these gemstones represent both the natural world and the human experience—transforming challenges into beauty and offering a rich tapestry of meaning to those who wear them. This article delves into the history, properties, and cultural significance of the June 21 birthstone, providing an in-depth look at why it remains a cherished symbol of grace and resilience.
History and Lore
The Pearl: A Timeless Symbol of Elegance
Pearls have a long and storied history, with evidence of their use dating back to ancient civilizations. In many cultures, pearls were considered symbols of purity, innocence, and serenity. Their association with the moon and water further reinforced their connection to feminine energy and emotional balance.
The earliest known records of pearls come from ancient Egypt, where they were highly prized and often buried with the dead as a symbol of rebirth and immortality. In ancient Greece and Rome, pearls were worn by the elite to signify wealth and status. Roman empresses, in particular, were known to adorn themselves with pearls, sometimes swallowing them for their supposed aphrodisiac properties.
During the Middle Ages, pearls were believed to possess mystical powers. They were thought to ward off evil spirits, protect the wearer from harm, and bring good fortune. In Renaissance Europe, pearls became a symbol of nobility and were frequently incorporated into royal jewelry collections.
In the 20th century, the discovery of cultured pearls by Japanese pearl farmer Kokichi Okada revolutionized the pearl industry. Cultured pearls, which are grown in controlled environments within mollusks, made pearls more accessible to the general public while preserving their timeless elegance and symbolic meaning.
Alexandrite: A Rare and Enigmatic Gemstone
Alexandrite, the second gemstone associated with June 21, is far more recent in its discovery. It was first identified in the early 19th century in the Ural Mountains of Russia, where it was named after Tsar Alexander II. Alexandrite is known for its remarkable color-changing property, appearing bluish-green in daylight and purplish-red under incandescent light. This phenomenon is due to the presence of chromium, which absorbs and re-emits light in different wavelengths depending on the lighting conditions.
The rarity of Alexandrite is one of the factors that make it so highly valued. Natural Alexandrite is extremely scarce, and most of the world’s supply comes from a few key locations, including Brazil, India, and Madagascar. Due to its scarcity and unique properties, Alexandrite is often considered one of the most valuable and sought-after gemstones in the world.
Alexandrite is also associated with transformation and adaptability, making it a fitting symbol for those born on June 21. Its ability to change color reflects the idea of personal growth and the capacity to embrace new challenges with grace and resilience.
Cultural Significance
Both pearls and Alexandrite have deep cultural significance, particularly in relation to birthstones and zodiac signs. In modern times, June 21 is associated with the zodiac sign Cancer, although some sources also mention Aquarius. Cancer is a water sign known for its emotional depth, intuition, and nurturing nature. Those born under this sign are often described as highly sensitive, imaginative, and empathetic individuals.
Pearls, with their associations with purity and wisdom, align well with the Cancerian traits of emotional depth and sensitivity. Alexandrite, with its connection to transformation and adaptability, complements the Cancerian need to navigate life’s changes with grace and strength.
In addition to their zodiacal associations, pearls and Alexandrite also have strong connections to the moon. Pearls are often linked to the moon due to their pearly sheen and their formation in water, while Alexandrite is sometimes referred to as the “moonstone” due to its color-changing properties and its rarity. This connection to the moon reinforces the idea of emotional balance, intuition, and the cyclical nature of life.
Geological Formation and Sources
The Formation of Pearls
Pearls are formed within the soft tissue of living mollusks, primarily oysters and mussels. Unlike other gemstones, which are formed under high pressure and temperature conditions deep within the Earth, pearls are created through a biological process. When an irritant, such as a grain of sand or a parasite, enters the shell of a mollusk, the mollusk responds by secreting layers of a substance called nacre around the irritant. Over time, these layers build up to form a pearl.
The quality and appearance of a pearl depend on a variety of factors, including the type of mollusk, the environment in which it is raised, and the care it receives during the cultivation process. Natural pearls are extremely rare, as the conditions required for their formation are highly specific and unpredictable. Cultured pearls, on the other hand, are grown in controlled environments, allowing for greater consistency in size, shape, and luster.
The most well-known sources of natural pearls include the Persian Gulf, the Red Sea, and the Indian Ocean. Cultured pearls are primarily produced in Japan, China, and the Philippines, where pearl farms have been established to cultivate high-quality pearls.
The Formation of Alexandrite
Alexandrite is a variety of the mineral chrysoberyl, which is composed of beryllium and aluminum. It is formed in metamorphic rocks under high-pressure and high-temperature conditions. The presence of chromium in the crystal structure is responsible for its distinctive color-changing property. Alexandrite is typically found in small, well-formed crystals, and its rarity is due in part to the specific geological conditions required for its formation.
The original source of Alexandrite in the Ural Mountains has been largely exhausted, and the current supply of natural Alexandrite comes from a few key locations around the world. Brazil is one of the most important sources, producing high-quality Alexandrite with a strong color change. India and Madagascar also produce Alexandrite, although the stones from these regions tend to have a more subtle color change compared to those from Brazil.
Due to the scarcity of natural Alexandrite, synthetic versions of the gemstone have been developed to meet the demand for this unique stone. Synthetic Alexandrite is created in a laboratory using the same chemical composition as natural Alexandrite but is significantly less valuable due to its abundance and lack of natural history.
Gemological Properties
Pearls: Beauty in Simplicity
Pearls are unique among gemstones in that they are not assigned a hardness on the Mohs scale, as they are composed of a different type of material. Instead, pearls are graded based on their luster, size, shape, and surface quality. The most highly valued pearls are those with a high luster, a smooth surface, and a perfectly round shape.
The luster of a pearl is one of its most defining characteristics. It is determined by the quality of the nacre layers and the way they reflect light. A pearl with a high luster will have a mirror-like surface that catches and reflects light in a dazzling way. Pearls with a lower luster may appear dull or flat, even if they are otherwise well-formed.
Pearls can be found in a variety of colors, including white, cream, pink, lavender, and even black. The color of a pearl is determined by the type of mollusk in which it is formed and the environment in which it is raised. For example, pearls from Akoya oysters are typically white or cream, while pearls from freshwater mussels can come in a range of colors, including pink, lavender, and green.
The size of a pearl is another important factor in its value. Larger pearls are more rare and therefore more valuable. The size of a pearl is measured in millimeters, and pearls can range from as small as 2 mm to as large as 15 mm or more.
Alexandrite: A Gemstone of Transformation
Alexandrite is a relatively hard gemstone, with a hardness of 8.5 to 9 on the Mohs scale, making it suitable for a variety of jewelry applications. Its color-changing property is one of its most distinctive features and is caused by the presence of chromium in the crystal structure. In daylight, Alexandrite appears bluish-green, while under incandescent light, it appears purplish-red. This phenomenon, known as the Alexandrite effect, is one of the reasons why Alexandrite is so highly valued.
The refractive index of Alexandrite is 1.74 to 1.78, which means that it has a relatively high refractive power and can display a strong brilliance when properly cut. Alexandrite is also known for its strong dispersion, which gives it a fiery sparkle when viewed in different lighting conditions.
Alexandrite is typically found in small, well-formed crystals, and its rarity is due in part to the specific geological conditions required for its formation. The presence of chromium in the crystal structure is essential for its color-changing properties, and the concentration of chromium determines the intensity of the color change.
Due to the scarcity of natural Alexandrite, synthetic versions of the gemstone have been developed to meet the demand for this unique stone. Synthetic Alexandrite is created in a laboratory using the same chemical composition as natural Alexandrite but is significantly less valuable due to its abundance and lack of natural history.

Care and Cleaning
Caring for Pearls
Pearls require special care due to their organic nature and sensitivity to certain substances. Unlike many other gemstones, pearls are not as hard and can be easily damaged if not handled properly. To maintain their luster and longevity, pearls should be cleaned with a soft, lint-free cloth and mild soap. Harsh chemicals, such as those found in perfumes, lotions, and cleaning products, can damage the surface of pearls and dull their luster.
Pearls should also be stored separately from other jewelry to prevent scratches. They should be kept in a soft pouch or a lined jewelry box to protect them from dust and moisture. It is also important to avoid exposing pearls to extreme temperatures or direct sunlight for extended periods, as this can cause them to dry out or become discolored.
When wearing pearls, it is best to put them on after applying makeup, perfume, and lotions to avoid exposing them to these substances. After wearing pearls, they should be wiped clean with a soft cloth and stored properly to ensure their longevity.
