The month of June holds a unique distinction in the world of gemology, offering not one, but three official birthstones: Pearl, Moonstone, and Alexandrite. This trio provides an unparalleled spectrum of color and character, ranging from the organic, soft luster of the pearl to the celestial glow of moonstone and the dramatic color-changing phenomenon of alexandrite. The diversity of June's gemstones means that individuals born in this month have a rich palette of options, each with its own distinct history, geological origin, and symbolic meaning. Unlike most gemstones formed deep within the Earth, pearls are created by living organisms, while moonstone captivates with its ethereal light, and alexandrite mystifies with its ability to shift from green to red. This article will explore the unique colors, origins, properties, and lore of these three remarkable gemstones, providing a comprehensive guide for enthusiasts, collectors, and anyone captivated by the beauty of June's birthstones.
A Rich Tapestry of History and Lore
The history of June's birthstones is as varied as the stones themselves, with each gem carrying centuries of cultural significance and belief. The journey from ancient talismans to modern birthstones reveals a fascinating evolution in how these gems are perceived.
The Ancient Pearl: A Symbol of Purity and Wisdom
The pearl is the oldest traditional birthstone for June, cherished for its natural elegance and profound symbolism. Unlike other gemstones that are mined from the Earth, pearls are organic gems formed within mollusks. For centuries, pearls have been associated with purity, sincerity, and spiritual wisdom. Their formation process, which begins when an irritant enters a mollusk, has been interpreted as a metaphor for life's challenges leading to beauty and inner peace. In various cultures, pearls were believed to bring calmness, clarity, and emotional healing to the wearer. They were often worn by royalty and nobility as symbols of status and integrity. The pearl’s enduring appeal lies in its timeless beauty and its deep connection to themes of love, marriage, and emotional balance. As the original June birthstone, it remains a classic choice for those who value tradition and understated elegance.
Moonstone: The Celestial Gem of Intuition
Moonstone, with its enchanting glow, has long been revered as a stone of mystery and intuition. Its name is derived from its moon-like appearance, and it is deeply connected to the divine feminine and lunar cycles. Historically, moonstone was believed to enhance intuition, inspire dreams, and promote emotional balance. It was often used in jewelry as a talisman for protection and good fortune. The stone's shimmering adularescence—a phenomenon where light appears to move across the gem's surface—was thought to be a captured piece of moonlight. This association with the moon made it a symbol of hope, love, and new beginnings. Moonstone’s lore is rich with beliefs about its ability to harmonize emotions and connect the wearer to their inner self, making it a favored stone for those seeking serenity and spiritual insight.
Alexandrite: The Modern Marvel of Transformation
Alexandrite is the most recent addition to the list of June birthstones, yet it has quickly gained a legendary status due to its rarity and unique optical properties. Discovered in the 19th century in the Ural Mountains of Russia, this gem was named after the future Tsar Alexander II. Its discovery was considered a good omen, and the stone became a national treasure. Alexandrite's most remarkable feature is its ability to change color from green in daylight to red under incandescent light, a phenomenon caused by chromium in its crystal structure. This dramatic shift led to the famous saying, "emerald by day, ruby by night." Symbolically, alexandrite represents duality, balance, and transformation. It is believed to bring good fortune, joy, and prosperity to its wearer. Its modern lore connects it to adaptability and the ability to see both sides of a situation, making it a powerful stone for personal growth.
Geological Formation and Global Sources
Understanding the origins of these gemstones reveals the fascinating natural processes that create their distinct colors and properties.
The Organic Creation of Pearls
Pearls are unique among gemstones as they are formed within living creatures. When a foreign particle, such as a grain of sand, enters a mollusk, the animal secretes layers of nacre—a composite of calcium carbonate and conchiolin—around the irritant to protect itself. Over time, these layers build up to form a pearl. Natural pearls are exceptionally rare and are now primarily sourced from historic collections. Cultured pearls, which involve the intentional introduction of an irritant into a mollusk, make up the vast majority of pearls on the market today. While pearls were historically harvested from the Persian Gulf, Sri Lanka, and the Gulf of Mannar, modern cultivation occurs in countries like Japan, China, and French Polynesia. The quality of a pearl is determined by the thickness and luster of its nacre.
The Earth-Born Glow of Moonstone
Moonstone is a variety of the mineral feldspar, specifically orthoclase or albite. Its formation occurs within igneous and metamorphic rocks. The gem's signature adularescence is the result of alternating layers of these two feldspars, which scatter light in a way that produces a floating, billowy effect. High-quality moonstone is primarily sourced from Sri Lanka, but it can also be found in India, Madagascar, and the United States. The finest specimens exhibit a clear, bluish sheen on a nearly colorless body. The geological conditions required for the formation of these specific feldspar layers make fine moonstone a prized find for gemologists and collectors.
The Rare and Colorful Alexandrite
Alexandrite is a variety of chrysoberyl, a mineral known for its hardness and durability. Its color-changing ability is due to trace amounts of chromium, the same element responsible for the green color of emeralds. The specific balance of light wavelengths absorbed and reflected by the chromium causes the gem to appear green in natural daylight and red under incandescent light. The original and most famous deposits were found in Russia's Ural Mountains, but these are now largely depleted. Today, alexandrite is mined in Brazil, Sri Lanka, Tanzania, and Madagascar. However, stones with the dramatic color shift of the original Russian finds are exceedingly rare and command premium prices. Due to this rarity, a significant portion of alexandrite in the jewelry market is lab-created, possessing the same chemical and physical properties as its natural counterpart.
Gemological Properties and Identification
Each of June's birthstones has a unique set of gemological characteristics that define its identity, durability, and value.
Pearl Properties
Pearls are measured on the Mohs scale of hardness at 2.5 to 4.5, making them relatively soft and susceptible to scratches. They exhibit a unique luster, which is the intense glow from within, and are graded on a system that evaluates their size, shape, color, luster, and surface quality. Pearls are composed primarily of calcium carbonate. Their organic nature means they are sensitive to acids, heat, and chemicals. The most common colors are white and cream, but they can also be found in shades of pink, silver, gold, and even black.
Moonstone Properties
Moonstone has a hardness of 6 on the Mohs scale, making it moderately durable but still requiring care to avoid scratches. Its most defining property is its adularescence, which gemologists grade based on the visibility, intensity, and movement of the light across the stone. Moonstone is typically transparent to translucent. Its chemical composition is a complex silicate of potassium and aluminum. While the classic moonstone is colorless with a blue sheen, it can also be found in shades of white, yellow, brown, and grey.
Alexandrite Properties
Alexandrite is a highly durable gemstone with a hardness of 8.5 on the Mohs scale, making it excellent for all types of jewelry. Its key identifying feature is its strong color change. The chemical formula for chrysoberyl is BeAl₂O₄, with chromium (Cr³⁺) as the color-changing impurity. Alexandrite is typically eye-clean, meaning it lacks visible inclusions. The value of alexandrite is heavily influenced by the intensity of its color change and the desirability of its body color. A 1-carat natural alexandrite can range in price from $500 to over $20,000, depending on these factors.

Its energy is thought to help one navigate life's contrasts and find harmony between opposing forces. Wearing alexandrite is said to stimulate creativity, encourage personal growth, and attract prosperity.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of these gemstones, given their distinct physical properties.
- Pearl Care: Due to their softness, pearls should be stored separately to avoid scratches. They are sensitive to chemicals, including perfume, hairspray, and cosmetics, so they should be the last thing you put on and the first thing you take off. Clean pearls with a soft, damp cloth; do not use ultrasonic cleaners or harsh chemicals.
- Moonstone Care: Moonstone should be protected from hard knocks and scratches. It is best cleaned with warm, soapy water and a soft brush. Avoid extreme temperature changes and harsh chemicals.
- Alexandrite Care: As the most durable of the three, alexandrite is relatively easy to care for. It can be cleaned with warm, soapy water and a soft brush. It is safe to use an ultrasonic cleaner, but steam cleaning should be avoided if the stone has fractures.
