June boasts a unique distinction among birthstones – not one, but three gemstones represent the month: Alexandrite, Pearl, and Moonstone. Each possesses a distinct history, captivating beauty, and symbolic meaning, offering a diverse range of choices for those born in the early summer months. This article will delve into the origins, properties, and cultural significance of these three June birthstones, drawing upon available historical and gemological information.
A History of June’s Gemstones
Historically, the pearl held the sole designation as June’s birthstone. Revered for millennia, pearls were considered symbols of purity, integrity, and marriage. During the Renaissance, they were associated with nobility and prestige, adorning the garments of royalty as displays of wealth. Ancient mythology linked pearls to the tears of mermaids or angels, or even fragments of the moon that had fallen into the sea.
However, the 19th century witnessed the discovery of a new contender: Alexandrite. This remarkable gem was first identified in Russia’s Ural Mountains in 1834. Its discovery coincided with the future coronation of Alexander II, and the stone was promptly named in his honor. The discovery story is somewhat debated, with attribution given to Finnish mineralogist Nils Gustaf Nordenskiöld, Ural Mine manager Vasilevich Kokovin, German mineralogy professor Gustav Rose, or Russian mineralogist Count L.A. Perovskii. Count Perovskii ultimately presented the gem to Alexander II on his birthday, solidifying its connection to the royal family. Initially, Russian alexandrite became a symbol of national pride, mirroring the colors of the Russian military.
Moonstone also enjoys a long and storied past, with mentions in Roman and Greek mythology, and a prominent place in Hindu beliefs where it was believed to be made of solidified moonbeams. Pliny the Elder, the Roman historian, named the stone “moonstone” due to its shimmering appearance, which he associated with the changing phases of the moon.
Alexandrite: The Color-Changing Gem
Alexandrite is the most recently recognized of the June birthstones and is prized for its exceptional optical phenomenon: its ability to change color under different lighting conditions. Under normal circumstances, it appears as a transparent yellow-green to greenish-blue stone. However, when exposed to polarized light, such as sunlight, it dramatically shifts to shades of red, dark purple, or orange. This color change is due to a phenomenon known as pleochroism. The most valued alexandrite exhibits a vivid green to bluish-green hue in daylight or fluorescent light, transforming into a deep red to purplish shade under incandescent light. This remarkable characteristic has been likened to an analogy of love, presenting itself in different forms.
Originally sourced exclusively from Russia’s Ural Mountains, these mines were largely depleted by the 1890s. Subsequent discoveries occurred in Brazil in 1987, followed by finds in Sri Lanka and Zimbabwe. Russian alexandrite, however, remains highly sought after and commands premium prices.
Pearls: Gifts from the Sea
Pearls are unique among gemstones as they are organic, formed within mollusks as a defense mechanism against irritants. When a foreign substance, such as a grain of sand, enters the mollusk’s shell, it secretes layers of nacre around it. Nacre, composed of calcium carbonate, builds up over time, creating the lustrous pearl.
The rarity of natural pearls, those formed without human intervention, contributes to their value. Most pearls available today are cultured pearls, grown on pearl farms where the irritant is intentionally inserted into the mollusk. Natural pearls are typically smaller and more irregularly shaped, while cultured pearls are often rounder and more uniform. Verification of a pearl’s origin can be confirmed through laboratory testing, such as by the Gemological Institute of America (GIA).
Several types of pearls are recognized, each with distinct characteristics:
- Akoya: Often considered the highest-quality cultured pearl, known for its excellent luster and round shape. These pearls are frequently bleached and dyed white with rose overtones.
- Freshwater: Formed by freshwater mollusks, these pearls typically have thicker nacre, more irregular shapes, and a lower luster compared to saltwater pearls, but are available in a wider range of colors.
Moonstone: The Stone of Dreams
Moonstone is celebrated for its adularescence – a shimmering, ethereal glow that appears to emanate from within the stone. This effect is caused by light scattering within the mineral’s layered structure. The most prized moonstones exhibit a blue sheen when viewed against a white background.
Chemically, moonstone is a form of the mineral feldspar. The interplay of light within the crystal layers creates its characteristic pearl-like luster. While often appearing milky white or gray, moonstone can also be found in shades of pink, orange, near-colorless, and even multicolored varieties.
Throughout history, moonstone has been associated with lunar deities in Roman and Greek mythology and with solidified moonbeams in Hindu traditions. It is believed to represent love, passion, and fertility, and is said to bring good luck and inspire beautiful dreams. Some cultures even used moonstone as a remedy for insomnia and sleepwalking, earning it the nickname “The Traveller’s Stone” and utilizing it as a protective charm for nighttime journeys.

Symbolism and Metaphysical Beliefs
Each of June’s birthstones carries its own set of symbolic meanings. Pearls traditionally represent purity, integrity, cleanliness, and marriage. Alexandrite, while lacking ancient symbolism, is often associated with heightened intuition and pleasure. Moonstone embodies love, passion, fertility, and good fortune, and is believed to promote restful sleep and inspire creativity.
Some cultures interpreted the color changes of alexandrite as indicators of potential danger. Rubies, often associated with July, are also mentioned as representing life, vitality, energy, and strength.
Caring for Your June Birthstone
Due to the varying hardness of these gemstones, care instructions differ. Pearls, being relatively soft, require gentle handling and should be protected from harsh chemicals and abrasive materials. Moonstone, while more durable than pearls, is still susceptible to scratching and should be stored carefully. Alexandrite, being a more durable gemstone, can withstand more wear but should still be protected from extreme temperatures and harsh impacts.
Conclusion
June’s birthstones – Alexandrite, Pearl, and Moonstone – offer a captivating blend of history, beauty, and symbolism. From the ancient allure of pearls to the modern fascination with alexandrite’s color-changing magic and the ethereal glow of moonstone, these gemstones continue to enchant and inspire. Each stone provides a unique connection to the month of June, representing its spontaneity, enthusiasm, and clarity.
