From the elegant luster of pearls to the mystical sheen of moonstone and the color-changing wonder of alexandrite, June's birthstones are as varied as they are fascinating.
The article is structured into thematic sections, covering the history and cultural significance, geological and physical properties, and care instructions for each gem. By the end, readers will have a comprehensive understanding of what makes these June birthstones so special.
History and Cultural Significance
Pearl: A Symbol of Purity and Elegance
Pearls have long been associated with purity, elegance, and grace. Unlike most gemstones, pearls are not mined from the earth but are formed within living organisms—specifically mollusks such as oysters and mussels. The process of pearl formation is a natural phenomenon that occurs when an irritant, such as a grain of sand, enters the soft tissue of a mollusk. In response, the mollusk begins to secrete layers of nacre, a substance composed of calcium carbonate and conchiolin, around the irritant. Over time, these layers build up to form a smooth, lustrous pearl.
Historically, pearls have held a place of prestige in many cultures. In ancient times, they were believed to be formed from teardrops of the gods or from the brain of dragons, as some Chinese legends suggest. Pearls were also considered a symbol of feminine beauty and were often worn by royalty and nobility. In medieval Europe, they were associated with divine favor and were used in religious ceremonies and royal jewelry.
Moonstone: The Mystical Light of the Moon
Moonstone is known for its ethereal glow, a phenomenon called adularescence, where light appears to shimmer and shift across the surface of the gem. This effect is caused by the interplay of light with the layers of feldspar within the stone. Moonstone has been revered for centuries, with myths surrounding its connection to the moon and its mystical properties.
In Roman and Greek mythology, moonstone was associated with lunar deities such as Diana and Selene. In Hindu tradition, moonstone is believed to be made of solidified moonbeams and is associated with the goddess Chandra, the personification of the moon. Moonstone is also known as "The Traveller's Stone," believed to offer protection during night journeys and to bring good fortune to those who travel.
Historically, moonstone has been used in jewelry and amulets to promote love, fertility, and emotional balance. It is also considered a stone of intuition and is believed to help individuals connect with their inner wisdom.
Alexandrite: The Enchanting Color-Changing Gem
Alexandrite is the rarest of the three June birthstones and is known for its remarkable color-changing property, known as pleochroism. In daylight, alexandrite appears green or greenish-blue, but under artificial light, it shifts to a deep red or violet hue. This dramatic transformation has earned it the nickname “Emerald by day, ruby by night.”
Discovered in the 19th century in Russia, alexandrite was named after Tsar Alexander II, who was born on the same day it was found. The gemstone quickly became a favorite among European royalty and nobility, who were captivated by its unique optical effects.
The color change in alexandrite is due to the presence of chromium in its chrysoberyl structure. Unlike most gemstones, alexandrite's color change is not due to pleochroism alone but also to the way it absorbs and reflects light. This phenomenon has made alexandrite one of the most prized and sought-after gemstones in the world.
Geological Formation and Sources
Pearl: The Organic Gemstone
Pearls are the only gemstones formed through a biological process rather than geological one. They are created within the mantle tissue of mollusks, primarily bivalves such as oysters and mussels. The formation of a pearl begins when a foreign particle, such as a grain of sand or a parasite, enters the mollusk's mantle. To protect itself from irritation, the mollusk begins to secrete nacre, a combination of calcium carbonate and conchiolin, which gradually builds up around the irritant.
The quality and luster of a pearl depend on several factors, including the species of mollusk, the environment in which it was formed, and the size and shape of the pearl. Pearls can be found in both saltwater and freshwater environments. Saltwater pearls are typically cultivated in oysters and include varieties such as Akoya, Tahitian, and South Sea pearls. Freshwater pearls, on the other hand, are formed in mussels and are often irregular in shape but can be dyed to enhance their color.
Moonstone: The Feldspar Wonder
Moonstone is a type of feldspar, a group of minerals that make up a significant portion of the Earth's crust. Feldspar is a silicate mineral composed of aluminum, oxygen, and various other elements such as potassium, sodium, and calcium. Moonstone belongs to the orthoclase and albite feldspar family and is characterized by its adularescent sheen, a result of the intergrowth of these two minerals within the crystal structure.
Moonstone forms in igneous and metamorphic rocks and is commonly found in pegmatites, which are coarse-grained igneous rocks formed from magma. The most highly prized moonstones come from India, especially the state of Bihar, where the blue sheen is most vivid. Other notable sources of moonstone include Sri Lanka, Brazil, the United States, and Madagascar.
Alexandrite: A Rare and Hard Mineral
Alexandrite is a member of the chrysoberyl mineral family, which is composed of beryllium aluminum oxide (BeAl₂O₄). It is a hard gemstone, ranking at 8.5 on the Mohs scale, which places it just below corundum (sapphire and ruby) and diamond in terms of hardness. This high hardness makes alexandrite a durable gemstone suitable for use in jewelry.
Alexandrite forms in pegmatites, which are igneous rocks rich in beryllium. It can also be found in alluvial deposits, where the gemstone has been eroded from its original location and carried by rivers and streams. The most famous source of alexandrite is the Ural Mountains in Russia, where it was first discovered in 1830. Today, high-quality alexandrite is primarily sourced from Brazil, Madagascar, and India.

Care and Cleaning
Pearl
Pearls are relatively soft and sensitive to chemicals, so they require gentle care. To clean pearls, use a soft, damp cloth to wipe away dirt and oils. Avoid using ultrasonic cleaners or steamers, as they can damage the nacre. Store pearls separately from other gemstones to prevent scratches. After wearing pearls, allow them to air dry before storing them in a soft pouch or lined jewelry box.
Moonstone
Moonstone is more durable than pearl but still requires careful handling. Clean moonstone with a soft cloth and mild soap and water solution. Avoid using harsh chemicals or abrasive cleaners, as they can dull the gemstone’s luster. Store moonstone in a separate compartment to avoid scratches from harder gemstones. Due to its perfect cleavage, moonstone should be handled with care to prevent chipping or breaking.
Alexandrite
Alexandrite is a hard gemstone, but it still benefits from gentle cleaning. Use a soft cloth and mild soap and water to clean the stone. Avoid exposing it to extreme temperatures or sudden temperature changes, as this can cause stress or cracking. Store alexandrite in a jewelry box to prevent scratches from other gemstones. Alexandrite’s color change is not affected by normal wear, but prolonged exposure to strong light can cause fading.
