Moonstone, a type of feldspar, is revered for its ethereal glow and spiritual associations. Alexandrite, the rarest of the three, is famed for its ability to shift hues under different lighting conditions. Together, these gemstones offer a diverse palette of colors, textures, and meanings, making June one of the most intriguing months in the birthstone calendar.
In the following sections, we will explore the historical and cultural significance of each stone, their geological properties, and the practical care tips necessary to preserve their beauty. This article is designed to inform and guide gemstone enthusiasts, jewelry buyers, and students of gemology in understanding the unique qualities that make these June birthstones so special.
History and Lore
Pearl: The Gem of the Sea
Pearls have been prized for centuries for their elegance and organic origin. Unlike other gemstones, pearls are formed within living organisms—specifically mollusks such as oysters, clams, and mussels. The process begins when an irritant, often a parasite or a small fragment of shell, enters the mollusk’s soft tissue. To protect itself, the mollusk secretes layers of nacre—a combination of conchiolin and aragonite—around the irritant, forming a pearl over time.
Historically, pearls have been symbols of purity, loyalty, and innocence. In ancient times, they were considered sacred in many cultures. For example, in Greek mythology, pearls were believed to be the tears of the gods. In China, they were associated with wisdom and longevity, and were often included in imperial regalia. In Japan, pearls have long been symbols of good fortune and are used in both ceremonial and everyday jewelry.
The name "pearl" itself has an interesting etymology. It comes from the Old French word perle, which is thought to be derived from the Latin word perna, meaning "leg." This may refer to the shape of the mollusk’s shell or the idea of "leg-of-lamb," as mentioned in one of the sources.
Pearls have also played a significant role in the jewelry industry, particularly in the 19th and 20th centuries. Cultured pearls, which are farmed rather than naturally formed, became widely available after the development of pearl cultivation techniques in the early 1900s. This innovation made pearls more accessible and affordable, cementing their place as a popular birthstone and jewelry piece.
Moonstone: The Enchanting Glow
Moonstone is a type of feldspar, a mineral that makes up a significant portion of the Earth’s crust. However, moonstone is not just any feldspar—it is distinguished by its iridescent sheen, known as adularescence, which gives it a soft, ethereal glow reminiscent of moonlight. This optical phenomenon is caused by the intergrowth of two feldspar minerals—orthoclase and albite—within the stone.
Moonstone has a long and storied history in various cultures. In ancient Rome, it was believed that moonstone was formed from the solid rays of the moon, and was associated with the lunar gods and goddesses. The Romans attributed healing and protective powers to the stone, believing it could enhance intuition and spiritual insight. In India, moonstone was known as “dream stones” and was thought to bring good dreams and enhance fertility. In Arabic culture, moonstone was considered an amulet for fertility, and was often worn by women seeking to conceive.
The Art Nouveau movement of the early 20th century saw a resurgence in the popularity of moonstone. Jewelry designers of that era incorporated moonstone into their pieces to evoke a sense of mystery and elegance. Today, moonstone is still valued for its unique beauty and is considered a symbol of health and longevity.
One of the more interesting legends associated with moonstone involves love and attraction. Some sources suggest that setting an intention with a moonstone during a full moon and carrying it until the next full moon could help attract one’s true love. While this belief is more of a modern romantic notion, it highlights the enduring cultural fascination with moonstone’s mystical properties.
Alexandrite: The Color-Changing Wonder
Alexandrite is the youngest of the three June birthstones, having only been discovered in the 19th century. It is a variety of the mineral chrysoberyl and is known for its remarkable color change, a phenomenon known as pleochroism. Under daylight or fluorescent light, alexandrite appears greenish or yellow-green, but under incandescent or candlelight, it shifts to a deep red or purplish hue. This color change has earned it the poetic description “emerald by day, ruby by night.”
The discovery of alexandrite is shrouded in legend and historical intrigue. According to some sources, it was discovered in the Ural Mountains of Russia in 1834, on the same day that the future Russian Czar Alexander II turned 18. The stone was named in his honor, symbolizing both royalty and youthful vitality. Other sources suggest that alexandrite may have been known earlier but was not widely recognized until its properties were fully understood.
Alexandrite is one of the rarest and most valuable of the three June birthstones. A genuine alexandrite necklace can be more costly than a diamond necklace, making it a luxurious and exclusive choice for jewelry. Due to its rarity, most alexandrite available on the market is synthetic, created in laboratories to mimic the natural gemstone’s properties.
The color-changing effect of alexandrite is often interpreted as a metaphor for love and transformation. The ability of the stone to appear different under various lighting conditions is seen as a reflection of the changing nature of love and relationships. This makes alexandrite a particularly meaningful gift for those celebrating a significant relationship milestone.
Geological Formation and Sources
Pearl: The Living Gem
Pearls are formed through a biological process rather than geological one. They develop within the soft tissue of mollusks such as oysters, clams, and mussels. The process begins when a foreign object, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk secretes nacre, a combination of conchiolin (a protein) and aragonite (a mineral), to coat the irritant. Over time, layers of nacre build up around the irritant, forming a pearl.
Pearls come in a variety of colors, including white, pink, black, and blue. The color of the pearl is determined by the shell color of the mollusk, as well as the type of nacre produced. For example, Akoya pearls, which are produced by saltwater oysters in Japan, are known for their white or pinkish hue, while black pearls from the South Pacific are formed in dark-shelled mollusks.
Pearls can be either natural or cultured. Natural pearls are extremely rare and are formed without human intervention. Cultured pearls, on the other hand, are produced through pearl farming, a process that involves introducing an irritant into the mollusk and allowing it to develop into a pearl over time. This technique has made pearls more accessible and affordable, while still maintaining their natural beauty and value.
Moonstone: The Feldspar with a Glow
Moonstone is a type of feldspar mineral, which is one of the most common minerals in the Earth’s crust. However, not all feldspar is moonstone—only those that exhibit the unique iridescent sheen known as adularescence are classified as such. This optical phenomenon occurs when light is scattered within the stone, creating a soft, glowing effect that resembles moonlight.
Moonstone is typically colorless or white, but it can also be found in pale blue, beige, green, orange, or brown hues, depending on the location and composition of the stone. The most prized moonstones are those with a strong, clear adularescence and a translucent to semi-transparent appearance.
Moonstone is found in several locations around the world, including Sri Lanka, India, and the United States. Sri Lankan moonstones are particularly highly valued for their pale blue color and vibrant sheen. Indian moonstones tend to be warmer in tone, with beige or golden hues, while American moonstones are often clear or white.
Alexandrite: The Color-Changing Gem
Alexandrite is a variety of the mineral chrysoberyl, which is also the same mineral that forms cymophane (cat’s eye) and normal chrysoberyl. What sets alexandrite apart is its unique color-changing ability, which is caused by the presence of chromium or vanadium within the crystal structure. These elements are responsible for the green or yellow-green color under daylight, and the red or purplish hue under incandescent light.
Alexandrite is extremely rare, and natural alexandrite is typically very expensive. The first alexandrite was discovered in the Ural Mountains of Russia, but today, it is also found in Sri Lanka, East Africa, and Brazil. However, Russian alexandrite is considered the most valuable and dramatic in terms of color change.
Due to its rarity and high cost, most alexandrite available in the market is synthetic or lab-grown. These synthetic stones are created using advanced crystal growth techniques and are chemically identical to their natural counterparts, but are more affordable and more widely available.
