June is a unique month in the gemological calendar, distinguished by its official designation of not one, not two, but three distinct birthstones: Pearl, Moonstone, and Alexandrite. This trio offers an unparalleled spectrum of color and character, from the organic luminescence of the pearl to the celestial glow of moonstone and the dramatic color-changing phenomenon of alexandrite. The question "what color is the birthstone for June?" cannot be answered with a single hue; instead, it invites an exploration into a world of shimmering whites, ethereal blues, and revolutionary shifts from green to red. This comprehensive guide delves into the gemological properties, historical significance, cultural lore, and practical care of each of June's celebrated birthstones, providing an expert overview for enthusiasts, collectors, and those born in the early days of summer.
The Luminous Pearl: A Symbol of Organic Elegance
The pearl stands as the most traditional and historically significant of the June birthstones. Unlike all other gemstones, which are mined from the earth, pearls are formed within living mollusks, a process that imbues them with a unique organic provenance. This origin story is central to their symbolism, which for centuries has been associated with purity, innocence, and wisdom.
History and Lore of the Pearl
The allure of the pearl dates back millennia. Historical records indicate that as early as 2300 BC, pearls were treasured by the royal family of China. In ancient Rome, their value was so immense that they were hailed as a symbol of ultimate power and status, with the historian Suetonius noting that the Roman general Vitellius financed an entire military campaign by selling just one of his mother's pearl earrings.
For centuries, natural pearls were the only available source, making them exceptionally rare and valuable. Their harvest required divers to risk their lives in dangerous oyster beds, and a single find could yield immense fortune. This rarity cemented their place as jewels for royalty and the ultra-wealthy across cultures, from the Persian Gulf to the courts of Europe. It was not until the early 20th century, with the pioneering work of Kokichi Mikimoto in Japan who perfected the technology for culturing pearls, that these gems became more accessible to a wider audience. Despite the advent of cultured pearls, natural pearls remain among the world's most prized and valuable gems.
Gemological Properties of Pearl
Pearls are composed of calcium carbonate in the form of the mineral aragonite, along with a protein called conchiolin. They are classified into several types based on their origin: Akoya (saltwater), South Sea (saltwater), Tahitian (saltwater), and Freshwater. Their color palette is diverse, ranging from the classic soft white and cream to pink, silver, and even deep black. The most iconic and traditional color, however, remains a soft, luminous white, which embodies faith and new beginnings. The luster of a high-quality pearl—its unique inner glow—is a key determinant of its value.
Symbolism and Metaphysical Beliefs
Pearls have long been associated with calming energies and emotional healing. They are believed to bring inner peace, clarity, and serenity to the wearer. In many traditions, pearls symbolize wisdom gained through experience and are thought to protect the wearer from negative energy. Their connection to water and the moon also links them to themes of purity and emotional balance.
Care and Cleaning
Due to their organic composition and relatively low hardness on the Mohs scale (around 2.5 to 4.5), pearls require special care. They are soft and can be easily scratched by harder materials. It is recommended to put on pearl jewelry last when dressing and to store it separately from other gems. Cleaning should be done gently with a soft, damp cloth; harsh chemicals, ultrasonic cleaners, and steam cleaners should be avoided as they can damage the nacre.
Moonstone: The Celestial Sheen
Moonstone, the second of June's traditional birthstones, captivates with its unique visual phenomenon known as adularescence. This optical effect gives the gem a ghostly, billowing light that seems to float just beneath the surface, reminiscent of the full moon's glow peeking through thin clouds.
History and Lore of Moonstone
Moonstone has been revered for centuries, particularly in Hindu and Roman mythology, where it was believed to be a gift from the moon goddess. In ancient India, it was a symbol of luck and inspiration. During the medieval period in Europe, it was thought to have the power to restore love and harmony and was often used in divination. Its ethereal beauty made it a signature gem of the Art Nouveau period in the late 19th and early 20th centuries, where jewelers like René Lalique incorporated it into their nature-inspired designs.
Gemological Properties of Moonstone
A member of the feldspar mineral group, moonstone is composed of orthoclase and albite. Its signature adularescence is caused by the intergrowth of these two feldspars as microscopic layers, which scatter light. Moonstone's color can vary significantly, from transparent and colorless to white, cream, yellow-brown, green, and even gray. The most prized specimens exhibit a blue sheen on a nearly colorless body. The gem has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable for everyday wear, though it should be protected from sharp blows.
Symbolism and Metaphysical Beliefs
Deeply connected to the moon and the divine feminine, moonstone is associated with emotional balance, intuition, and inner growth. It is considered a stone of new beginnings and is believed to enhance creativity, nurture love, and provide a calming effect on the emotions. Its gentle energy makes it a popular choice for those seeking serenity and spiritual insight.
Care and Cleaning
Moonstone should be handled with care to avoid fracturing. It is best cleaned with warm, soapy water and a soft brush. Avoid exposing it to extreme temperature changes and harsh chemicals. Store it in a soft cloth or padded jewelry box to prevent scratches.
Alexandrite: The Remarkable Color-Changer
Alexandrite is the most modern and perhaps the most magical of the June birthstones. Discovered in the 19th century, its extraordinary ability to change color based on the light source has earned it the nickname "emerald by day, ruby by night."
History and Lore of Alexandrite
Alexandrite's history is relatively recent. It was discovered in the Ural Mountains of Russia in 1830 and named in honor of the future Tsar Alexander II. The gem's red and green colors mirrored the old imperial Russian military colors, leading to its immediate acclaim as a symbol of national pride and imperial power. It became a favorite of the Russian nobility. Its rarity, especially of fine quality stones, has persisted, making it a highly sought-after collector's gem.
Gemological Properties of Alexandrite
Alexandrite is a variety of the mineral chrysoberyl. Its remarkable color change is due to the presence of chromium in its crystal structure, which absorbs light in the yellow portion of the spectrum. In natural daylight or fluorescent light, which is rich in blue and green wavelengths, alexandrite appears greenish-blue to green. In incandescent or incandescent light, which is rich in red and yellow wavelengths, it appears red to purplish-red. This phenomenon is a defining characteristic and a primary test for authenticity. Alexandrite is a very durable gem, with a hardness of 8.5 on the Mohs scale, making it excellent for all types of jewelry. Due to the extreme rarity of natural alexandrite, most commercial jewelry features lab-created stones that possess the exact same chemical and optical properties.
Symbolism and Metaphysical Beliefs
The dual nature of alexandrite's color change has led to its association with duality and transformation. It is considered a stone of good omens, believed to boost intuition, stimulate creativity, and encourage personal growth. For those born under the sign of Gemini, it is particularly significant, embodying the adaptable and multifaceted nature of the sign.
Care and Cleaning
With its high hardness and lack of cleavage, alexandrite is quite resilient. It can be cleaned safely with warm, soapy water, a soft brush, and an ultrasonic cleaner. It is, however, sensitive to extreme heat, which can alter its color, so it should not be exposed to rapid temperature changes.

The Spectrum of June: Color and Availability
The diversity of June's birthstones is reflected in their color palette. Pearls offer soft whites, creams, and pinks. Moonstone provides glowing whites with flashes of blue. Alexandrite presents the most dramatic shift, from green in daylight to red in artificial light. This makes June one of the most dynamic months for gemstone color.
This variety also extends to price and availability. Pearls, especially cultured freshwater pearls, offer a classic and often affordable option. Moonstone provides a unique aesthetic at a moderate price point. Natural alexandrite is one of the rarest and most expensive gems in the world, but lab-created alexandrite offers the same stunning color-change effect at a much more accessible price, making it a popular modern choice for June-born individuals. The presence of three official birthstones ensures that anyone born in June can find a gem that perfectly suits their personal style, budget, and aesthetic preference.
