From the luminous white of the Pearl to the color-changing magic of Alexandrite and the ethereal shimmer of Moonstone, June's birthstones offer a rich tapestry of aesthetic and symbolic value. This article delves into the gemological properties, historical significance, and cultural lore of these three gems, exploring the colors that define them and the enduring fascination they inspire.
Historical and Cultural Significance
Pearl: A Symbol of Purity and Elegance
Pearls have held a place of reverence in human culture for millennia. As early as 2300 BC in ancient China, pearls were treasured by the royal family and associated with power and prestige. In ancient Rome, pearls were considered symbols of wealth and status, often worn by the elite as a display of their affluence. The soft, luminous white of the Pearl has long been associated with purity, innocence, and new beginnings.
Pearls are unique among gemstones in that they are formed within living mollusks, requiring no cutting or polishing to reveal their natural luster. This natural beauty has contributed to their enduring appeal. By the early 20th century, the cultivation of pearls in Japan revolutionized the availability of this gem, making it more accessible while still maintaining the high value of natural pearls.
The white of the Pearl is the most iconic and traditional color associated with June’s birthstone, though pearls can occur in a spectrum of colors, including pink, black, and gold. These variations are influenced by the type of mollusk that produces them, with freshwater and seawater pearls each offering their own distinct hues.
Moonstone: The Mystical Shimmer
Moonstone, the second of June’s birthstones, carries a history steeped in mysticism and divine symbolism. In Hinduism and Roman mythology, moonstone was believed to be a gift from the moon goddess, imbuing it with a sense of sacredness and spiritual connection. In ancient India, it was considered a stone of luck and inspiration, while in medieval Europe, it was thought to restore love and harmony.
The unique optical phenomenon known as adularescence, which gives moonstone its characteristic iridescent shimmer, has made it especially popular in certain eras. During the Art Nouveau period, for example, moonstone was widely used in jewelry design due to its ethereal, dreamlike appearance. This shimmer typically manifests as a soft blue sheen over a milky white background, though moonstone can also appear in other colors, including green, yellow-brown, and grey.
The soft, glowing hues of moonstone are often described as gentle and calming, making it a symbol of emotional balance and the divine feminine. These qualities have contributed to its enduring presence in both historical and modern jewelry traditions.
Alexandrite: The Enigmatic Color-Change Gem
Alexandrite is the youngest of June’s birthstones, having been discovered in the Ural Mountains of Russia in 1830. Named in honor of Tsar Alexander II, this gemstone quickly became a symbol of imperial power and glory. Its most striking characteristic is its ability to change color depending on the light source—shifting from green in daylight to red or reddish-purple under incandescent light.
This color-changing property, known as the alexandrite effect, is a result of the gemstone’s chemical composition and the way it interacts with different wavelengths of light. The phenomenon is so rare that natural alexandrite is considered one of the most valuable and sought-after gemstones in the world. Due to its scarcity, most alexandrite used in jewelry today is lab-created, offering the same chemical and optical properties as its natural counterpart.
Alexandrite’s color transformation is often interpreted as a symbol of adaptability and transformation, making it a fitting birthstone for June, a month that marks the transition from spring to summer. Its rare and mystical qualities have also contributed to its association with good fortune and renewal, making it a popular choice for those seeking a meaningful and visually striking gemstone.
Geological Formation and Sources
Pearl Formation
Pearls are formed within the soft tissue of mollusks, such as oysters and mussels, when an irritant—such as a grain of sand—enters the shell. In response, the mollusk secretes layers of nacre (also known as mother-of-pearl) around the irritant, gradually forming a smooth, rounded pearl. The process can take several years, and the resulting pearl is composed of calcium carbonate, conchiolin, and water.
Natural pearls are extremely rare, which is why the cultivation of pearls was developed in the early 20th century. This technique, pioneered in Japan, involves the intentional introduction of an irritant into the mollusk, allowing for the controlled production of pearls. Cultivated pearls are now the most commonly available type, though they are still highly valued for their beauty and rarity.
Pearls can vary in color depending on the type of mollusk and the environment in which they are formed. Seawater pearls, such as Akoya, Tahitian, and South Sea pearls, tend to have a wider range of colors, including white, pink, black, and gold. Freshwater pearls, on the other hand, are typically white or cream in color, though they can also appear in shades of lavender, pink, and green.
Moonstone Formation
Moonstone is a type of feldspar, specifically a member of the plagioclase feldspar group. Its characteristic iridescence is the result of a phenomenon known as adularescence, which occurs due to the intergrowth of different layers of feldspar within the stone. These layers refract light in such a way that a soft, glowing shimmer is produced, often appearing as a blue sheen over a milky white background.
Moonstone is found in various parts of the world, with India being the primary source of high-quality moonstone. Other notable sources include Sri Lanka, the United States, and Brazil. The stone is typically mined in pegmatite deposits, where it forms alongside other minerals such as quartz and mica. The conditions necessary for the development of moonstone involve slow-cooling magma and the presence of certain chemical elements, which allow for the formation of its unique optical properties.
Alexandrite Formation
Alexandrite is a rare variety of the mineral chrysoberyl, distinguished by its remarkable color-changing properties. It is composed primarily of beryllium aluminum oxide (BeAl₂O₄) and contains trace amounts of chromium or vanadium, which are responsible for its color change. The stone’s ability to shift color from green in daylight to red in incandescent light is due to the way these trace elements absorb and reflect different wavelengths of light.
Natural alexandrite is found in only a few locations around the world, including the Ural Mountains in Russia, where it was first discovered, as well as Brazil, Sri Lanka, and Madagascar. The conditions necessary for the formation of alexandrite involve high-temperature and high-pressure environments, where the right combination of minerals and elements can come together to produce this unique gemstone.
Due to its rarity and the high demand for alexandrite, most of the alexandrite used in jewelry today is lab-created. These lab-grown stones are chemically identical to their natural counterparts and exhibit the same color-changing properties. This has made alexandrite more accessible to collectors and jewelry enthusiasts, while still preserving its mystique and value.
Gemological Properties

| Pearl | White, pink, black, gold | 2.5–4.5 | Calcium carbonate (nacre), conchiolin, water | 1.53–1.68 | None (nacreous luster) |
| Moonstone | White with blue sheen, green, yellow-brown, grey | 6–6.5 | Sodium aluminum silicate (plagioclase feldspar) | 1.518–1.526 | Adularescence |
| Alexandrite | Green in daylight, red in incandescent light | 8.5 | Beryllium aluminum oxide (BeAl₂O₄) with chromium or vanadium | 1.74–1.76 | Color change (alexandrite effect) |
Pearl
Pearls are known for their soft, lustrous appearance and are composed of layers of nacre, which is primarily calcium carbonate. Their color can vary widely, including white, pink, black, and gold, depending on the type of mollusk and the environment in which they are formed. Pearls have a relatively low hardness on the Mohs scale, ranging from 2.5 to 4.5, which makes them susceptible to scratches and abrasions.
Due to their organic origin, pearls do not have a refractive index in the same way that mineral gemstones do. Instead, they exhibit a nacreous luster, which gives them their characteristic glow. This luster is a result of the way light is reflected off the multiple layers of nacre, creating a soft, iridescent effect.
Moonstone
Moonstone is a type of feldspar with a hardness of 6 to 6.5 on the Mohs scale. It is composed of sodium aluminum silicate and is known for its unique optical phenomenon known as adularescence. This effect is caused by the intergrowth of different layers of feldspar within the stone, which refract light in a way that creates a soft, glowing shimmer.
The refractive index of moonstone ranges from 1.518 to 1.526, and its color can vary from white with a blue sheen to green, yellow-brown, and grey. The most valuable and sought-after moonstone is that which exhibits a strong blue sheen, as this is considered the most desirable and visually striking.
Alexandrite
Alexandrite is a rare variety of chrysoberyl with a hardness of 8.5 on the Mohs scale, making it one of the harder gemstones. It is composed of beryllium aluminum oxide and contains trace amounts of chromium or vanadium, which are responsible for its color-changing properties.
The refractive index of alexandrite ranges from 1.74 to 1.76, and it is best known for its color-changing effect, known as the alexandrite effect. This phenomenon occurs when the stone is viewed under different light sources—shifting from green in daylight to red in incandescent light. The color change is due to the way the trace elements in the stone absorb and reflect different wavelengths of light.
