From the luminous elegance of pearls to the mystical glow of moonstone and the dazzling color change of alexandrite, June’s birthstones reflect the month’s themes of renewal, balance, and celebration.
This article explores the history, gemological properties, and cultural significance of June’s birthstones. We’ll examine how these gems have been used throughout history, what makes them scientifically unique, and what they symbolize in various cultures. Whether you are a jewelry buyer, a gemstone enthusiast, or a student of gemology, this in-depth look at June’s birthstones will provide valuable insight into their enduring appeal.
History and Lore
The Origins of June Birthstones
The tradition of assigning gemstones to specific months has roots in ancient cultures, particularly in Mesopotamia and Egypt. Over time, these associations evolved, with different cultures adding their own interpretations. By the 14th century, European jewelers had developed a more formalized system of birthstones, which was further refined in the 19th and 20th centuries.
June’s association with three gemstones is relatively modern. The earliest known reference to pearls as a June birthstone comes from an 1870 pamphlet published by Tiffany & Co., titled Gregorian Birthstone Poems. In this pamphlet, pearls were assigned to June. Over the years, additional gemstones were added to the list. Moonstone was officially recognized as a June birthstone in the 20th century, and alexandrite followed later in the same century.
Cultural Significance and Symbolism
Each of June’s birthstones carries its own set of symbolic meanings, often tied to the natural world and human emotions. Pearls, for example, are often associated with purity, wisdom, and transformation. In ancient Greece, pearls were believed to be the hardened tears of the goddess Aphrodite, while in Chinese mythology, they were symbols of power and wisdom held by dragons. Cleopatra famously dissolved a pearl in vinegar and drank it to demonstrate her wealth and affection for Mark Antony.
Moonstone, with its milky, ethereal glow, has long been linked to the moon and femininity. It was believed to enhance intuition and emotional balance, especially in women. Ancient legends suggest that moonstone could attract love, particularly when set with intention during a full moon. The gemstone’s connection to the moon and its soft, dreamlike appearance made it a popular choice for jewelry associated with romance and mysticism.
Alexandrite, the youngest of the three, was discovered in the 19th century in the Ural Mountains of Russia. Named after Czar Alexander II, the gemstone quickly gained popularity among the Russian aristocracy. Its most striking feature is its ability to change color—appearing green in daylight and red under incandescent light. This color change was seen as a metaphor for transformation and duality. Alexandrite became a symbol of balance, making it particularly fitting for June, a month associated with both the summer solstice and the beginning of summer.
Geological Formation and Sources
Pearl: A Living Creation
Unlike most gemstones, which are formed through geological processes, pearls are created by living organisms. They are formed within mollusks such as oysters and mussels when an irritant, such as a grain of sand, enters the shell. In response to this foreign object, the mollusk secretes layers of nacre—a smooth, iridescent substance—around the irritant, gradually forming a pearl.
There are two main types of pearls: natural and cultured. Natural pearls are extremely rare and are formed without human intervention, while cultured pearls are produced through a process called nucleation, where a small bead or piece of mantle tissue is introduced into the mollusk to stimulate pearl formation. Cultured pearls are far more common and are available in a wide range of shapes, sizes, and colors.
Saltwater pearls, such as those from the oceans, are typically round and smooth, while freshwater pearls, which are produced in rivers and lakes, can take on a variety of shapes, from round to baroque. Pearls are found in various parts of the world, including the Persian Gulf, Japan, China, and the United States. The quality and appearance of pearls can vary depending on the species of mollusk and the environment in which they are formed.
Moonstone: A Gem of the Moon
Moonstone is a type of feldspar mineral that is known for its unique optical phenomenon called adularescence. This effect gives the stone a soft, glowing light that appears to move across its surface, resembling the shimmer of moonlight. Moonstone is most commonly found in shades of white and gray, but it can also appear in colors such as blue, green, and peach.
Moonstone is formed in igneous and metamorphic rocks, particularly in pegmatites and schists. The stone’s adularescence is caused by the intergrowth of two different types of feldspar—orthoclase and albite. These layers are so fine that they scatter light in a way that creates the characteristic shimmer.
The most prized moonstone is known as “blue moonstone,” which displays a striking blue flash. This variety is typically found in India, Sri Lanka, and Madagascar. Other sources of moonstone include the United States, Brazil, and Norway. The availability of moonstone has made it a popular and affordable option for jewelry, and its mystical properties have made it a favorite among those who believe in the power of gemstones.
Alexandrite: The Color-Changing Gem
Alexandrite is a rare and valuable gemstone that is known for its remarkable color-changing property. Under natural daylight, alexandrite appears green or yellow-green, but under incandescent light, it changes to a deep red or purplish-red. This color change is due to the presence of trace amounts of chromium in the crystal structure.
Alexandrite is a variety of the mineral chrysoberyl. It was first discovered in the Ural Mountains of Russia in the 1830s, and it was named after Czar Alexander II, who was celebrating his birthday when the gemstone was found. The Ural deposits soon became exhausted, and for many years, alexandrite was a rarity. However, new deposits were discovered in Brazil in the 1990s, making the gemstone more available to collectors and jewelers.
Brazilian alexandrite tends to have a more pronounced color change and is often more valuable than stones from other sources. Other sources of alexandrite include Sri Lanka, Tanzania, and Madagascar. The most valuable alexandrite is known as “true alexandrite,” which exhibits a complete and vivid color change from green in daylight to red in incandescent light.
Gemological Properties
Pearl: The Organic Gem
Pearls are unique among gemstones because they are the only naturally formed gems that are produced by living organisms. They are composed primarily of calcium carbonate in the form of aragonite, which is bound together by conchiolin, a protein secreted by the mollusk. The surface of a pearl is covered with a thin layer of nacre, which is responsible for its luster and iridescence.
The quality of a pearl is determined by several factors, including its luster, surface quality, size, shape, and color. Luster is the most important factor because it determines how light interacts with the pearl’s surface. A high-quality pearl will have a sharp, mirror-like luster, while a lower-quality pearl may appear dull or cloudy.
Pearls are relatively soft compared to other gemstones, with a hardness of around 2.5 to 4.5 on the Mohs scale. This means that they are easily scratched and can be damaged by contact with harder materials. Pearls are also sensitive to acids, heat, and abrasives, so they require special care when cleaning and storing.
Moonstone: The Shimmering Feldspar
Moonstone is a type of feldspar mineral that is composed primarily of potassium aluminum silicate. It has a hardness of around 6 to 6.5 on the Mohs scale, making it relatively durable, but it is still softer than many other gemstones. Moonstone has a vitreous to pearly luster and is typically translucent to opaque.
The most important gemological feature of moonstone is its adularescence, which is the soft, glowing light that appears to move across the stone’s surface. This effect is caused by the scattering of light between the intergrown layers of orthoclase and albite feldspar. The best moonstone specimens display a strong and consistent adularescence, with the light appearing to float just beneath the surface.
Moonstone is available in a variety of colors, but the most prized is the blue moonstone, which exhibits a striking blue flash. Other colors include white, gray, green, and peach. Moonstone is relatively affordable compared to other gemstones, making it a popular choice for jewelry.
Alexandrite: The Color-Changing Chrysoberyl
Alexandrite is a variety of the mineral chrysoberyl, which is composed of beryllium aluminum oxide. It has a hardness of 8.5 to 9 on the Mohs scale, making it one of the hardest and most durable gemstones. Alexandrite is typically found in a range of colors, from green to red, depending on the light source.
The most distinctive property of alexandrite is its color change, which is caused by the presence of trace amounts of chromium in the crystal structure. In daylight, the chromium absorbs certain wavelengths of light, making the stone appear green or yellow-green. Under incandescent light, the absorption is different, causing the stone to appear red or purplish-red. This effect is one of the most dramatic and visually striking in the world of gemstones.
The quality of alexandrite is determined by the strength and clarity of its color change, as well as its overall clarity and cut. The most valuable alexandrite is known as “true alexandrite,” which exhibits a complete and vivid color change from green in daylight to red in incandescent light. Alexandrite is a rare gemstone, and high-quality specimens can be very valuable.
