June is a month rich in symbolism and diversity when it comes to birthstones. Unlike most months that are associated with a single gemstone, June boasts three official birthstones: pearl, moonstone, and alexandrite. Each of these gemstones carries a unique history, distinct gemological properties, and a wealth of cultural and metaphysical significance. From the soft luster of pearls to the ethereal glow of moonstone and the mesmerizing color-changing phenomenon of alexandrite, June’s birthstones reflect the month’s natural beauty and emotional depth.
This article delves into the origins, properties, and meanings of these three gems, offering a comprehensive guide for gemstone enthusiasts, jewelry buyers, and students of gemology. The information presented is based on detailed and verified data from expert sources, ensuring accuracy and authenticity.
A Historical Overview of June Birthstones
The tradition of associating gemstones with birth months dates back centuries, with roots in ancient Roman, Greek, and even biblical times. June birthstones, however, have a particularly intriguing history due to the inclusion of three distinct stones.
The Pearl: An Ancient Symbol of Purity and Harmony
The pearl has been revered for millennia, often regarded as the most timeless of all birthstones. Ancient civilizations such as the Greeks, Romans, and Chinese attributed profound significance to pearls. In Roman mythology, pearls were associated with Venus, the goddess of love, symbolizing beauty, grace, and fertility. Chinese emperors valued pearls as symbols of wisdom and immortality, often adorning themselves with pearl-encrusted robes and jewelry.
The pearl is unique among birthstones in that it is the only one not mined from the earth, but rather formed inside living mollusks such as oysters, mussels, and clams. This organic origin has contributed to its mystique and allure.
Moonstone: A Stone of Emotion and Intuition
Moonstone has a long and storied history in both the East and the West. In India, it has been a sacred gem for centuries, associated with the goddess Parvati and believed to bring emotional balance and spiritual insight. In ancient Rome, moonstone was thought to be formed from moonbeams, and it was often used in amulets to enhance intuition and promote calmness.
Moonstone’s ethereal glow, known as adularescence, gives it a soft, luminous sheen that has captivated cultures throughout history. Its gentle energy makes it a popular choice for those seeking emotional stability and connection with their inner self.
Alexandrite: A Modern Marvel of Color Change
Alexandrite is the youngest of June’s birthstones, first discovered in the 19th century. Named after Tsar Alexander II of Russia, the gem was initially found in the Ural Mountains and quickly became a symbol of power and transformation. Its most remarkable feature is its color-changing property, known as pleochroism, where the stone appears green in daylight and red under incandescent light.
Though once considered the rarest and most valuable form of chrysoberyl, natural alexandrite is now less common due to the depletion of the original Russian deposits. Today, most alexandrite used in jewelry is either sourced from other regions such as Brazil and Sri Lanka or lab-created, allowing for wider accessibility and continued appreciation of its magical properties.
The Geology and Formation of June Birthstones
Understanding the geological formation of each gemstone provides insight into their rarity, beauty, and unique characteristics.
Pearl: An Organic Marvel
Pearls are organic gemstones formed within the soft tissue of living mollusks. The process begins when an irritant—such as a grain of sand or a parasite—enters the mollusk’s shell. In response, the mollusk secretes nacre, a combination of conchiolin and aragonite, to coat the irritant and prevent further irritation. Over time, layers of nacre build up, forming a smooth, lustrous pearl.
There are two main types of pearls: natural and cultured. Natural pearls occur without human intervention, while cultured pearls are formed with the assistance of pearl farmers who introduce a bead nucleus into the mollusk to encourage pearl formation. Cultured pearls are more commonly available in the market today.
Pearls can be found in a range of colors, including white, pink, black, and even rare blue or green hues. The color of a pearl is largely determined by the species of mollusk and the environment in which it was formed. Notable pearl-producing regions include the Persian Gulf, Japan, and more recently, China.
Moonstone: A Silicate Enchantment
Moonstone is a type of feldspar mineral, specifically orthoclase and albite, which form a layered structure. The stone’s characteristic glow, known as adularescence, is the result of light scattering between these layers. This effect is most visible in translucent moonstone and is responsible for the stone’s dreamy, luminous appearance.
Moonstone is typically white or pale blue, with a milky or translucent body. It is relatively soft, with a Mohs hardness of 6–6.5, which makes it susceptible to scratches and damage. As a result, moonstone is often used in jewelry that is worn less frequently, such as pendants or earrings.
Natural moonstone is found in several parts of the world, including India, Sri Lanka, and the United States (particularly in Virginia). The finest moonstone is known for its strong adularescence and clarity.
Alexandrite: A Chrysoberyl Transformation
Alexandrite is a rare and captivating gemstone formed from the mineral chrysoberyl. Its color-changing property is due to the presence of chromium impurities within its crystal structure. Under daylight, the chromium absorbs certain wavelengths of light, causing the stone to appear green or greenish-blue. Under artificial light, the absorbed wavelengths shift, allowing the stone to appear red or purplish-red.
Alexandrite is one of the hardest gemstones, with a Mohs hardness of 8.5, making it highly durable and suitable for everyday wear. However, its rarity and the cost of natural alexandrite have led to the development of lab-created alexandrite, which replicates the chemical and optical properties of its natural counterpart.
Natural alexandrite was originally found in the Ural Mountains of Russia, but these deposits are now exhausted. Today, the primary sources of alexandrite are Brazil, Sri Lanka, and East Africa, with Brazil producing some of the most notable specimens. The Whiney Alexandrite (17.08 carats) and the Sauer Alexandrite (122,400 carats) are among the most famous examples of the gemstone.
Gemological Properties and Aesthetic Appeal
Each of June’s birthstones has unique physical and optical properties that contribute to its beauty and value.
Pearl

Alexandrite is one of the most visually striking gemstones due to its color-changing property. This phenomenon is so rare and captivating that alexandrite is often referred to as the “emerald by day, ruby by night.” Its high hardness and brilliance make it a desirable choice for fine jewelry.
Symbolism and Metaphysical Beliefs
Throughout history, gemstones have been believed to hold special powers and energies. June’s birthstones are no exception, with each carrying its own set of meanings and metaphysical properties.
Pearl: Wisdom, Purity, and Emotional Balance
Pearls are often associated with wisdom, serenity, and emotional balance. In many cultures, they are believed to bring inner peace and clarity, making them especially beneficial for those undergoing emotional or spiritual transitions.
In Chinese tradition, pearls are associated with longevity and immortality, and are often used in jewelry meant to ward off negative energies. In the West, pearls are considered a symbol of purity and innocence, and are often given as gifts to mark significant life milestones such as weddings or births.
Moonstone: Intuition, Feminine Energy, and Emotional Stability
Moonstone is closely linked to emotional balance and intuition. It is often considered a feminine stone, representing the nurturing and creative aspects of the female spirit. In ancient India, moonstone was believed to enhance fertility and emotional stability, and it was commonly worn by women during pregnancy.
Modern metaphysical beliefs associate moonstone with inner peace and emotional healing, making it a popular choice for those seeking to overcome anxiety, mood swings, or emotional trauma. It is also said to enhance intuition and psychic awareness, making it a favorite among spiritual practitioners.
Alexandrite: Transformation, Luck, and Passion
Alexandrite is known for its transformative energy, symbolizing change, growth, and the power of light. Due to its color-changing property, it is often associated with duality and balance, and is believed to help individuals navigate life transitions with grace and confidence.
In some traditions, alexandrite is considered a stone of good fortune, particularly in love and career. It is said to enhance passion and creativity, making it an ideal gift for those entering new phases in life. Its rarity and beauty also make it a powerful symbol of rare and precious moments.
Caring for June Birthstones
Proper care is essential to preserve the beauty and longevity of June’s birthstones. Each gemstone requires specific handling and cleaning methods due to its unique properties.
