June is a month of transformation, marking the transition from the gentle bloom of spring to the vibrant energy of summer. As a result, the gemstones associated with this month reflect this duality through a rich and varied color palette. June is uniquely blessed with not one, but three official birthstones: pearl, alexandrite, and moonstone. Each of these gemstones brings its own distinct colors and symbolic meanings, making June one of the most colorful and historically rich months in the world of gemstones.
This article explores the colors and properties of each of June's birthstones, their origins in the birthstone tradition, and the cultural and historical significance they have carried across time. From the classic white of pearls to the color-changing marvel of alexandrite and the ethereal shimmer of moonstone, June’s birthstones offer a visual and symbolic tapestry that is as diverse as the month itself.
History and Lore of June Birthstones
The tradition of associating gemstones with specific months of the year is ancient, with roots in both Western and Eastern cultures. While the exact origins of the modern birthstone calendar are unclear, it is believed that the earliest references date back to the Breastplate of Aaron, mentioned in the Hebrew Bible, which listed twelve stones for the twelve tribes of Israel. Over time, these associations evolved and were adapted by various cultures, including the ancient Greeks, Romans, and Chinese, who each developed their own interpretations of gemstone symbolism.
Pearls, the oldest and most traditional of June's birthstones, have been cherished for millennia. Ancient civilizations revered pearls for their organic formation and their association with purity and wisdom. In ancient Rome, pearls were considered a symbol of wealth and status, often worn by emperors and aristocrats. In China, pearls were believed to have healing properties and were used in traditional medicine. The pearl's soft, white color was associated with innocence and serenity, making it a popular choice in religious and ceremonial settings.
Moonstone, while less ancient in its association with June, has a long history in folklore and mysticism. It was believed by the Romans to be formed from moonbeams, and it was thought to bring calmness and balance to the wearer. In India, moonstone was considered sacred and was used in spiritual practices. It was also popular among the Victorians, who associated it with romance and intuition.
Alexandrite is the most recent addition to June’s birthstone lineup, having been discovered in the early 19th century. Named after Tsar Alexander II of Russia, it was quickly embraced by European royalty due to its rare and magical property of changing color under different lighting. Its inclusion in the June birthstone tradition reflects the evolving nature of gemstone symbolism and the continued fascination with color-shifting phenomena.
Together, these three gemstones have built a rich and enduring legacy for June, each contributing to the month's identity in the world of gemology.
Geological Formation and Sources of June Birthstones
Each of June's birthstones is formed through a unique geological process, resulting in their distinct physical and optical properties.
Pearl: The Organic Wonder
Pearls are the only gemstones formed entirely by living organisms, specifically mollusks such as oysters and mussels. The process begins when a foreign object, such as a grain of sand or a parasite, enters the soft tissue of a mollusk. To protect itself, the mollusk secretes layers of a substance called nacre, which is primarily composed of calcium carbonate and conchiolin. Over time, these layers build up around the irritant, forming a smooth, rounded pearl.
Pearls can be found in both freshwater and saltwater environments. Freshwater pearls are typically produced by mussels and can vary greatly in shape and color, ranging from white to pink, lavender, and even black. Saltwater pearls, such as those from the South Sea and Tahitian varieties, are known for their larger size and more consistent shape.
The most common color for pearls is white or cream, but they can also appear in pink, lavender, gray, and black, depending on the type of mollusk and the environment in which they were formed.
Moonstone: The Iridescent Gem
Moonstone is a variety of the feldspar mineral group and is known for its characteristic "schiller" effect, a shimmering iridescence that resembles the soft light of the moon. This optical phenomenon, called adularescence, is caused by the intergrowth of two types of feldspar—orthoclase and albite—that reflect light at different angles.
Moonstone is typically found in igneous and metamorphic rocks and is most commonly sourced from India, Sri Lanka, and Burma. The most prized moonstones are those with a strong blue shimmer, known as "blue moonstone." Other varieties may display green, white, or yellow hues.
Moonstone is generally milky white in color but can vary in tone and transparency. It is a relatively soft gemstone, with a hardness of 6 to 6.5 on the Mohs scale, making it more delicate than many other gemstones.
Alexandrite: The Color-Changing Marvel
Alexandrite is a rare and valuable gemstone that is known for its unique ability to change color depending on the type of light it is exposed to. In daylight, alexandrite typically appears green, while under incandescent light, it shifts to a reddish or purplish hue. This phenomenon is caused by the presence of chromium in the crystal structure, which absorbs and re-emits light at different wavelengths.
Alexandrite is a variety of the chrysoberyl mineral and is formed under high-pressure and high-temperature conditions deep within the Earth's crust. Natural alexandrite is extremely rare, and most alexandrite in the jewelry market today is lab-created. These synthetic stones have the same chemical composition and optical properties as their natural counterparts.
The most famous source of natural alexandrite is the Ural Mountains in Russia, where the stone was first discovered in the early 19th century. Other sources include Brazil, India, Madagascar, and Sri Lanka.

Care and Cleaning of June Birthstones
Proper care is essential to maintaining the beauty and longevity of June's birthstones. Due to their varying hardness and sensitivity to light and chemicals, each gemstone requires specific handling and cleaning methods.
Pearl
Pearls are soft and porous, making them vulnerable to damage from harsh chemicals, heat, and friction. They should be cleaned with a soft, damp cloth and a mild soap solution. Avoid using ultrasonic cleaners or steam cleaners, as these can cause the nacre to flake or the luster to dull.
Store pearls separately from other gemstones to prevent scratching. It is best to wear them after applying perfume or cosmetics, as these can leave a residue on the surface of the pearls.
Moonstone
Moonstone should be cleaned with a soft cloth and warm, soapy water. Avoid using abrasive materials or harsh chemicals, as these can dull the surface or damage the schiller effect. Ultrasonic and steam cleaners should also be avoided.
Store moonstone in a soft pouch to prevent scratches. It is best to avoid exposing it to direct sunlight for extended periods, as this can cause fading or discoloration.
Alexandrite
Alexandrite is a durable gemstone but should still be cleaned with care. A soft cloth and mild soap solution are suitable for most cleaning needs. Avoid using ultrasonic or steam cleaners, as these can cause internal stress and potentially damage the stone.
Alexandrite should be stored in a dark place to preserve its color-changing properties. Direct exposure to bright light can cause the stone to lose its vibrant hues over time.
