The month of June holds a unique distinction in the world of birthstones. While most months are associated with a single gem, June boasts a trio of captivating stones: the classic pearl, the ethereal moonstone, and the rare, color-changing alexandrite. This diversity offers individuals born in this summer month a remarkable range of choices, each with its own distinct story, appearance, and symbolic meaning. From the organic luster of pearls formed in living mollusks to the celestial glow of moonstone and the dramatic color shift of alexandrite, June’s birthstones represent purity, intuition, and transformation. This comprehensive guide delves into the history, properties, sources, and significance of these three enchanting gems, providing essential knowledge for gemstone enthusiasts, jewelry buyers, and students of gemology.
The Official Trio: A Historical Overview
Unlike most months with a single, well-defined birthstone, June’s official list is notably varied. The primary traditional choice is the pearl, a gem that has been cherished for centuries for its organic beauty and symbolic purity. However, modern birthstone lists, such as those from the American Gem Society (AGS) and the Gemological Institute of America (GIA), have expanded June’s offerings to include moonstone and alexandrite. This expansion reflects a desire to provide a wider palette of colors, price points, and characteristics for June birthdays. The GIA notes that June is one of only three months (alongside August and December) that has three official birthstones, giving individuals a variety of beautiful options to suit their mood, style, or budget. This trio is unique not only in number but also in origin: one is organic (pearl), one is a feldspar with a special optical effect (moonstone), and one is a rare variety of chrysoberyl (alexandrite).
Pearl: The Organic Gem of Purity and Wisdom
The pearl stands as the oldest and most traditional of June’s birthstones. Unlike all other gemstones, which are minerals formed deep within the Earth’s crust, pearls are created by living organisms. They are organic gems that grow inside the tissue of a living saltwater or freshwater mollusk, such as an oyster or mussel. The formation process begins when an irritant, like a grain of sand or a parasite, becomes lodged inside the mollusk’s shell. In response, the mollusk secretes a substance called nacre, a composite of crystalline calcium carbonate and an organic protein called conchiolin, layer by layer around the irritant. Over time, these layers build up to form a lustrous pearl. Cultured pearls are the result of human intervention, where a technician intentionally introduces an irritant into the mollusk to stimulate pearl production, a process that accounts for the vast majority of pearls available on the market today.
The history of the pearl is shrouded in myth and fascination. Ancients from the Middle East believed pearls were teardrops fallen from heaven, while the Chinese fancied that they originated from the brain of a dragon. Christopher Columbus and his contemporaries speculated that mollusks formed pearls from dew drops. Beyond these legends, pearls have been symbols of purity, wisdom, and emotional balance for millennia. They are believed to bring inner peace, calmness, and clarity to the wearer. In terms of symbolism, pearls represent purity, wisdom, and calm. Their serene, classic beauty makes them a timeless wardrobe staple, beloved by women of all ages.
Pearls are found in oceans, lakes, and rivers around the world. Major sources for natural and cultured pearls include the waters of Japan (notably for Akoya pearls), the South Sea regions (for large South Sea pearls), and various freshwater sources in China and the United States (for freshwater pearls). The value of a pearl is determined by a combination of factors, including its luster, surface quality, shape, size, and color. While classic white is the most sought-after, pearls can also be found in shades of pink, silver, and gold.
Moonstone: The Celestial Glow of Intuition
The second of June’s birthstones, moonstone, is revered for its captivating optical phenomenon known as adularescence. This is the soft, billowy, and shimmering light that seems to float just beneath the surface of the stone, moving as the gem is rotated. This ethereal glow, reminiscent of moonlight, gives moonstone its name and magical appearance. It is a variety of the mineral feldspar, specifically orthoclase or albite, and is known for nurturing emotional balance, enhancing intuition, and connecting the wearer with lunar energy. Associated with divine feminine energy, moonstone is often favored by those seeking serenity and creativity.
Symbolically, moonstone is tied to intuition, emotional healing, and feminine energy. It is believed to enhance creativity and intuition, making it a stone of inspiration and inner growth. The GIA confirms that moonstone is one of June’s three official birthstones, alongside pearl and alexandrite. Its color range is typically colorless or white, but it can also exhibit shades of peach, gray, and blue. The most prized moonstones display a vivid blue adularescence against a colorless background. Moonstone is sourced from various locations, including Sri Lanka, India, and Madagascar. In terms of durability, moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it relatively durable but requiring some care to avoid scratches and impacts.
Alexandrite: The Rare Color-Changer
Alexandrite is the most recent and rarest addition to June’s birthstone family. Discovered in the Ural Mountains of Russia in the 1830s, it is a rare variety of the mineral chrysoberyl. Its most extraordinary and defining characteristic is its ability to change color based on the lighting. In natural daylight or fluorescent light, it appears as a vibrant blue-green, while under incandescent light or candlelight, it shifts to a purplish-red or raspberry red. This dramatic color change is caused by the presence of chromium in its crystal structure, which absorbs light in a specific way. The GIA describes this phenomenon as "extraordinary," and it is the primary reason for the gem’s value and allure.
The history of alexandrite is closely tied to its discovery. It was named after the future Russian Tsar Alexander II, as the gem’s red and green colors mirrored the old imperial Russian military colors. This connection made it a symbol of national pride and a favorite of the Russian aristocracy. Today, alexandrite is considered a stone of transformation, embodying duality and change. It is believed to boost intuition, stimulate creativity, and encourage personal growth. Its symbolism is deeply linked to change, creativity, and awakening.
Alexandrite is exceptionally rare, and significant deposits are limited. The original Russian sources are largely depleted, but new deposits have been found in Brazil, Sri Lanka, and East Africa. However, fine-quality alexandrite with a strong color change is still very scarce and commands a high price in the market. It is a durable gemstone with a hardness of 8.5 on the Mohs scale, making it suitable for various types of jewelry, though its rarity often places it in protective settings.
Gemological Properties: A Comparative Overview
The three June birthstones differ significantly in their composition, hardness, and optical properties. Understanding these differences is crucial for proper care and appreciation. The following table summarizes their key gemological characteristics as derived from the provided sources.
| Gemstone | Mineral Family | Chemical Composition | Hardness (Mohs Scale) | Key Optical Property | Primary Color(s) |
|---|---|---|---|---|---|
| Pearl | Organic | Calcium carbonate (nacre) | 2.5 - 4.5 (variable) | Luster | White, cream, pink, silver, gold |
| Moonstone | Feldspar | KAlSi₃O₈ (Orthoclase) | 6 - 6.5 | Adularescence | Colorless, white, peach, gray, blue |
| Alexandrite | Chrysoberyl | BeAl₂O₄ | 8.5 | Strong Color Change | Daylight: blue-green; Incandescent: red/purple |
Pearl is the softest of the trio due to its organic nature. Its hardness is not constant but is generally rated between 2.5 and 4.5 on the Mohs scale. This makes it susceptible to scratching and abrasion, requiring careful handling. Its primary value lies in its luster, the sharp, mirror-like reflection from its surface.
Moonstone, a member of the feldspar group, has a moderate hardness of 6 to 6.5. This makes it durable enough for everyday wear in jewelry, though it should be protected from hard blows. Its defining feature is adularescence, a moving light effect that is unique to this gem.
Alexandrite is the hardest and most durable of the three, with a rating of 8.5 on the Mohs scale. This exceptional hardness, combined with its rarity and dramatic color change, makes it one of the most valuable and sought-after gemstones in the world. Its color change is the most critical factor in determining its value, with the most prized specimens showing a vivid blue-green to red/purple shift.

Beyond their physical beauty, all three June birthstones are rich in symbolic meaning and metaphysical beliefs, which have been passed down through cultures and generations.
- Pearl: As a symbol of purity, wisdom, and calm, pearls are believed to soothe emotions and stabilize moods. They are often associated with tears, but in a positive context, they represent the cleansing of emotions and the attainment of inner peace. Wearing a pearl is thought to bring clarity and a sense of tranquility to the wearer.
- Moonstone: Deeply connected to the moon and feminine energy, moonstone is a stone of intuition and emotional healing. It is believed to enhance creativity, promote inspiration, and balance hormones. Its gentle, soothing energy is said to help one connect with their subconscious and explore their inner world.
- Alexandrite: This gem is a powerful symbol of change and transformation. Its ability to change color is seen as a metaphor for life’s dualities and the need for adaptability. It is believed to stimulate creativity, boost intuition, and encourage personal growth, making it a stone for those undergoing significant life transitions or seeking to unlock their creative potential.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone jewelry. The different physical properties of June’s birthstones necessitate specific cleaning and handling methods.
Pearl Care: Due to their organic nature and relative softness, pearls require the most care. They are sensitive to acids, cosmetics, and even perspiration. It is recommended to put on pearl jewelry after applying makeup and perfume. To clean pearls, simply wipe them with a soft, damp cloth after each wear. Avoid ultrasonic cleaners, steam cleaners, and harsh chemicals, as these can damage the nacre. Store pearls separately from other jewelry to prevent scratching.
Moonstone Care: With a hardness of 6-6.5, moonstone is more durable than pearl but still requires caution. It is best cleaned with warm, soapy water and a soft brush. Avoid sudden temperature changes and harsh chemicals. While it can be worn daily, it is advisable to remove it during activities that could subject it to hard impacts.
Alexandrite Care: As the hardest of the three, alexandrite is quite durable and can be cleaned with warm, soapy water and a soft brush. It is also safe for ultrasonic cleaning (except for stones with fractures or inclusions). However, due to its high value and rarity, it is always wise to have it inspected by a professional jeweler periodically to ensure the setting is secure.
