June is a month rich in gemological diversity, celebrated with three distinct birthstones—pearl, moonstone, and alexandrite. Each of these gemstones carries its own unique appearance, historical significance, and symbolic meaning. Together, they offer a broad spectrum of visual appeal, from the soft elegance of pearls to the ethereal glow of moonstone and the dramatic color-changing effect of alexandrite. This article delves into the appearance of June’s birthstones, exploring their physical characteristics, historical uses, and cultural significance.
History and Lore
The tradition of assigning gemstones to months of the year has ancient origins, though the specific list of birthstones has evolved over time. June has historically been associated with the pearl, a gemstone formed within living mollusks and revered for its natural beauty and symbolism of purity and wisdom. The inclusion of moonstone and alexandrite in June’s birthstone lineup reflects the evolution of gemstone popularity and availability, particularly in the 20th century.
Pearls have been treasured for millennia, with references to their formation and beauty found in ancient texts. In ancient Greece and Rome, pearls were symbols of wealth, power, and divine favor. The pearl's association with purity and wisdom made it a favored gemstone for royalty and religious figures alike. By the early 20th century, the American National Retail Jewelers Association standardized birthstone lists, and pearls remained the traditional June birthstone.
Moonstone, on the other hand, is a more modern addition. Its ethereal glow and connection to lunar energy made it a popular choice in Europe during the 19th and 20th centuries. Moonstone was often used in jewelry to promote emotional balance and intuition, aligning with the mystical and spiritual trends of the time.
Alexandrite was added to the June birthstone list in the 1950s. This rare gemstone, known for its ability to change color under different lighting conditions, quickly became a favorite among gemstone enthusiasts and jewelry collectors. Alexandrite's unique properties and striking visual appeal made it an ideal addition to June’s birthstone selection, offering a modern and vibrant alternative to the more traditional pearls and moonstones.
Geological Formation and Sources
Pearl
Pearls are unique among gemstones because they are organic, formed within living mollusks such as oysters and mussels. The process begins when a foreign particle, such as a grain of sand, enters the mollusk’s tissue. To protect itself, the mollusk coats the particle in layers of nacre, a substance composed of calcium carbonate and conchiolin. Over time, these layers build up to form a pearl. The most prized pearls are those with a high luster, round shape, and uniform color.
Natural pearls are extremely rare and valuable, but most pearls available today are cultured. Cultured pearls are created by introducing a small bead or piece of mantle tissue into a mollusk, which then secretes nacre around it. This process mimics the natural formation of pearls but can be controlled to produce consistent results. The primary sources of pearls include Japan, China, and the coastal regions of the Indian Ocean and the Persian Gulf.
Moonstone
Moonstone is a type of feldspar that exhibits a phenomenon known as adularescence, a soft, pearly glow that appears to float just below the surface of the stone. This effect is caused by the intergrowth of two feldspar minerals—orthoclase and albite—with varying refractive indices. The alternating layers of these minerals scatter light, creating the characteristic shimmer.
Moonstone is typically white or gray with flashes of blue, though it can also be found in other colors such as yellow, green, and even rare orange. The most prized moonstones are those with a strong, clear adularescence and a clean, transparent body. The primary sources of moonstone include Sri Lanka, India, and the United States, particularly in the state of Florida. Sri Lankan moonstone, known for its intense blue sheen, is considered the finest and most valuable.
Alexandrite
Alexandrite is a rare and highly prized gemstone known for its color-changing properties. Under daylight, alexandrite appears green, while under incandescent light, it shifts to a reddish or purplish hue. This phenomenon, known as the alexandrite effect, is caused by the absorption and re-emission of light due to the presence of chromium in the stone.
Alexandrite is a chrysoberyl mineral that forms in metamorphic rocks under high-pressure and high-temperature conditions. The most famous source of alexandrite is the Ural Mountains in Russia, where it was first discovered in 1830. Today, alexandrite is also found in Brazil, Madagascar, and Sri Lanka. Brazilian alexandrite is particularly notable for its vivid color change and is often considered the finest available.
Gemological Properties
Pearl
Pearls are known for their soft, smooth texture and their natural luster. They are relatively soft, ranking between 2.5 and 4.5 on the Mohs scale of hardness. This low hardness means that pearls require careful handling to avoid scratches and damage. Pearls are also sensitive to acids, perfumes, and other chemicals, which can dull their luster or cause surface erosion.
The most common colors of pearls are white, cream, and pink, though black, golden, and even multicolored pearls can also be found. The quality of a pearl is determined by several factors, including its luster, surface quality, shape, and color. High-quality pearls have a deep, mirror-like luster, a smooth surface free of blemishes, and a round or well-formed shape.
Moonstone
Moonstone is a translucent gemstone that ranges in color from white to gray, with flashes of blue, yellow, or other colors. The most valuable moonstones are those with a strong, clear adularescence and a clean, transparent body. Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable but still requiring careful handling to avoid scratches and chips.
The unique shimmer of moonstone, known as adularescence, is one of its most distinguishing features. This effect is caused by the intergrowth of two feldspar minerals, which scatter light and create the soft, pearly glow. Moonstone is often cut in cabochon to enhance its visual appeal and to showcase its adularescence.
Alexandrite
Alexandrite is a transparent gemstone that exhibits a dramatic color change under different lighting conditions. Under daylight, it appears green, while under incandescent light, it shifts to a reddish or purplish hue. This phenomenon, known as the alexandrite effect, is caused by the absorption and re-emission of light due to the presence of chromium in the stone.
Alexandrite has a hardness of 8.5 to 9 on the Mohs scale, making it relatively durable and suitable for everyday wear. The most valuable alexandrites are those with a strong color change, a clean, transparent body, and a high refractive index. Alexandrite is often cut in step or mixed cuts to enhance its brilliance and to showcase its color-changing properties.

Care and Cleaning
Pearl
Pearls require special care to maintain their luster and to prevent damage. Because pearls are soft and porous, they are sensitive to acids, perfumes, and other chemicals. It is important to avoid wearing pearl jewelry when applying lotions, perfumes, or other products that may contain harsh chemicals.
To clean pearls, it is best to use a soft, damp cloth to gently wipe them. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the nacre and the metal settings. After wearing pearls, it is also important to store them in a soft, breathable pouch to prevent scratches and to keep them dry.
Moonstone
Moonstone requires careful handling to avoid scratches and chips. Because moonstone is relatively soft, it is important to avoid wearing it in situations where it may be exposed to hard surfaces or abrasive materials. Moonstone is also sensitive to heat and should be kept away from direct sunlight or high temperatures.
