June boasts a unique distinction among the calendar months: it is represented by not one, but three distinct and captivating birthstones – alexandrite, pearl, and moonstone. Each gem carries its own rich history, fascinating geological origins, and symbolic significance, offering a diverse range of choices for those born in the heart of summer. This article will delve into the characteristics of each of these June birthstones, exploring their origins, properties, and the lore that surrounds them.
A Historical Tapestry
The association of gemstones with specific months and their corresponding astrological signs dates back centuries, though the specific assignments have evolved over time. The modern list of birthstones gained prominence in 1912, established by the National Association of Jewelers. However, the history of each gem extends far beyond this standardization. Pearls, arguably the oldest of the three, have been revered for millennia, adorning royalty and symbolizing purity and wealth across numerous cultures. Moonstone also enjoys a long and storied past, linked to lunar deities in Roman and Greek mythology and believed to possess magical properties in Hindu traditions. Alexandrite, the newest addition to the June birthstone family, has a comparatively recent history, its discovery in the 19th century coinciding with the reign of Emperor Alexander II of Russia, from whom it derives its name.
Alexandrite: The Color-Changing Gem
Alexandrite is perhaps the most remarkable of the three June birthstones due to its exceptional optical phenomenon: its ability to change color depending on the light source. Under daylight or fluorescent light, alexandrite typically appears green or bluish-green. However, when exposed to incandescent light, it transforms to reveal shades of red or purple. This dramatic shift is a result of pleochroism, a property where the gem absorbs different wavelengths of light depending on the viewing angle.
This rare gem is a variety of the mineral chrysoberyl. The most prized alexandrite exhibits a vivid green to bluish-green hue in daylight and a deep red to purplish tone under incandescent light. Initially discovered in the Ural Mountains of Russia in the 1830s, the gem was named in honor of Czar Alexander II, as its colors mirrored the Russian imperial military colors. The original Russian mines eventually became depleted, but alexandrite is now also mined in Brazil, Sri Lanka, and East Africa. High-quality alexandrite is considered extremely rare and commands a high price, with most stones weighing less than 5 carats.
Pearl: A Classic of Timeless Beauty
Pearls, formed within the soft tissue of a living shelled mollusk, represent a timeless symbol of elegance and purity. Natural pearls, formed spontaneously without human intervention, are rare and often irregular in shape. The majority of pearls used in jewelry today are cultured pearls, created through a deliberate process of inserting an irritant into the mollusk to stimulate nacre production.
Pearls come in a wide range of colors, including white, cream, pink, blue, purple, brown, and black. Historically, white and cream pearls were the most common, but modern pearl farming techniques have expanded the available color palette. The color of a pearl is determined by the type of mollusk and the environment in which it grows. Pearls are composed of nacre, the iridescent substance lining the mollusk’s shell, and their color reflects the growing animal’s display. Beyond the body color, pearls often exhibit an overtone, a secondary hue that shimmers across the surface, adding to their visual appeal. Common overtones include pink, purple, green, and blue. Pearls commemorate both third and thirtieth wedding anniversaries, further solidifying their significance as meaningful gifts.
Moonstone: The Stone of Lunar Magic
Moonstone, the third June birthstone, is renowned for its captivating adularescence – a shimmering, ethereal glow that appears to emanate from within the stone. This optical phenomenon is caused by the scattering of light within the gem’s layered structure. The name “moonstone” was coined by the Roman historian Pliny the Elder, who observed the gem’s resemblance to the shifting phases of the moon.
Chemically, moonstone is a form of the mineral feldspar. The most valued moonstones exhibit a blue sheen when viewed against a white background. Throughout history, moonstone has been associated with lunar deities in various cultures. In Roman and Greek mythology, it was linked to the moon goddesses, while in Hindu tradition, it was believed to be formed from solidified moonbeams. Moonstone is often associated with love, passion, and fertility, and is believed to bring good luck and inspire beautiful dreams. It was also used as a protective charm for travelers, earning it the nickname “The Traveller’s Stone.” Moonstone can be found in a variety of colors, including milky white, gray, pink, orange, and even multicolored varieties.
Gemological Properties at a Glance
The following table summarizes key gemological properties of the three June birthstones:

Symbolism and Metaphysical Beliefs
Each of the June birthstones carries a unique set of symbolic meanings and metaphysical beliefs. Alexandrite is often associated with luck and prosperity, while pearls symbolize purity, innocence, and wisdom. Moonstone is believed to enhance intuition, promote emotional balance, and encourage new beginnings. These symbolic associations contribute to the enduring appeal of these gemstones and their significance as personal talismans.
Care and Cleaning
Due to their varying hardness levels, each June birthstone requires specific care to maintain its beauty. Alexandrite, being a relatively hard gem, can be cleaned with warm, soapy water and a soft brush. Pearls, being much softer, are susceptible to damage from harsh chemicals and abrasive cleaners. They should be cleaned gently with a soft cloth and mild soap, and should never be immersed in harsh chemicals. Moonstone, with its moderate hardness, should also be cleaned with a soft cloth and mild soap, avoiding ultrasonic cleaners and harsh chemicals.
Conclusion
The three birthstones of June – alexandrite, pearl, and moonstone – represent a captivating blend of history, beauty, and symbolism. From the color-changing magic of alexandrite to the timeless elegance of pearls and the ethereal glow of moonstone, each gem offers a unique and meaningful connection to the summer solstice. Whether chosen for their aesthetic appeal, their historical significance, or their perceived metaphysical properties, these June birthstones continue to enchant and inspire generations.
