History and Lore of June’s Birthstones
Pearl: The Ancient Gem of Purity and Wisdom
Pearl is the oldest of June’s birthstones and has been associated with the month since ancient times. The Romans, for instance, linked pearls to Venus, the goddess of love and beauty, whom they believed was born in June. This association reinforced pearls as symbols of purity, love, and divine beauty.
Throughout history, pearls have been treasured by royalty and the elite. Their organic origin—formed within the soft tissues of mollusks—sets them apart from most other gemstones, which are formed through geological processes. This natural formation process has long been associated with wisdom, as pearls are created over time through patience and the gradual accumulation of layers.
Pearls were also deeply valued in Eastern cultures, particularly in China and Japan, where they were considered to bring good fortune and were used in both ceremonial and decorative contexts. In Chinese tradition, pearls symbolized purity and the moon, and were often used in imperial jewelry.
Today, pearls remain a classic and enduring symbol of elegance and simplicity. They are often associated with milestones such as anniversaries and graduations, and are a popular choice for both formal and casual jewelry.
Moonstone: The Traditional June Birthstone of Emotional Balance
Moonstone became an official June birthstone in 1912, marking its inclusion in the modern birthstone calendar. The stone is admired for its soft, glowing sheen, known as adularescence, which creates an ethereal shimmer that resembles moonlight. This effect is caused by the reflection of light between layers of different minerals within the stone, most commonly orthoclase and albite.
Moonstone has long been associated with the moon and lunar energy. In ancient times, it was believed to be formed from moonbeams solidified into stone. This connection to the moon made it a symbol of intuition, emotional balance, and feminine energy. It was often used in rituals and amulets meant to protect and guide individuals during times of change or uncertainty.
In India, moonstone is considered one of the most powerful gemstones for emotional and spiritual healing. It is believed to help calm the mind, enhance creativity, and provide a sense of calm and clarity. This aligns with the broader tradition of using gemstones for their metaphysical and healing properties.
As a traditional June birthstone, moonstone offers a more mystical and bohemian alternative to the classic pearl. It is particularly popular in contemporary and alternative jewelry styles, where its dreamlike quality and subtle shimmer are highly valued.
Alexandrite: The Modern June Birthstone of Transformation and Rarity
Alexandrite is the most recent addition to June’s birthstone list, having been officially recognized in 1950. Discovered in the 19th century in Russia, alexandrite is known for its rare and dramatic color-changing properties. In daylight, it appears greenish, while under incandescent light, it takes on a reddish hue. This phenomenon, known as the alexandrite effect, is caused by the stone’s unique chemical composition and the way it absorbs and reflects light.
The discovery of alexandrite was considered a marvel of nature and a symbol of good fortune. Named in honor of Tsar Alexander II of Russia, the stone quickly became a favorite among the Russian nobility. Its rarity and mystical properties contributed to its status as a symbol of transformation, growth, and personal evolution.
As a modern June birthstone, alexandrite appeals to those who appreciate both scientific rarity and symbolic meaning. Its color-changing properties make it a captivating and dynamic gemstone, often associated with adaptability and resilience. In some cultures, alexandrite is believed to bring luck and to help individuals navigate transitions in life.
The addition of alexandrite to June’s birthstone list reflects the evolving nature of gemstone traditions and the growing appreciation for unique and rare materials. It also highlights the importance of scientific discovery in shaping the modern gemstone industry.
Geological Formation and Sources
Pearl: Organic Formation in Mollusks
Unlike most gemstones, which are formed through geological processes, pearls are organic gemstones that develop within the soft tissues of mollusks such as oysters and mussels. The formation of a pearl begins when a foreign particle, such as a grain of sand, enters the mollusk’s mantle. To protect itself, the mollusk secretes layers of nacre, a combination of calcium carbonate and conchiolin, around the irritant.
Over time, these layers build up to form a rounded pearl. The size, shape, and color of a pearl depend on various factors, including the type of mollusk, the environment, and the length of time the pearl has been forming. Cultured pearls, which are now the majority of pearls on the market, are produced through human intervention, where a small bead or piece of mantle tissue is inserted into the mollusk to stimulate pearl formation.
Pearls are found in both saltwater and freshwater environments. Saltwater pearls are primarily produced in oysters in regions such as the Persian Gulf, Japan, and the South Pacific, while freshwater pearls are formed in mussels and are commonly found in lakes and rivers in China and the United States.
Moonstone: Feldspar with an Ethereal Glow
Moonstone is a variety of feldspar, a group of minerals that make up a significant portion of the Earth's crust. Specifically, moonstone is a type of orthoclase feldspar that contains layers of albite, another feldspar mineral. These alternating layers create the characteristic adularescence, the soft, glowing sheen that gives moonstone its ethereal appearance.
Moonstone is typically found in granitic rocks, where it forms as a result of the slow cooling of magma. It is often associated with pegmatite deposits, which are rich in rare minerals and gemstones. The best-quality moonstone is found in Sri Lanka, where it is known for its intense blue sheen. Other notable sources include India, the United States, and Madagascar.
Moonstone is relatively soft, with a Mohs hardness of 6 to 6.5, making it more vulnerable to scratches and damage than harder gemstones. As a result, it is often used in jewelry that is worn less frequently or protected from friction.
Alexandrite: A Rare and Color-Changing Gem
Alexandrite is a chrysoberyl gemstone, a mineral composed of beryllium aluminum oxide (BeAl₂O₄). Its most distinctive feature is the alexandrite effect, a phenomenon in which the stone changes color depending on the light source. In daylight, it appears greenish due to the absorption of red wavelengths, while under incandescent light, it appears reddish because it reflects those wavelengths.
This unique property is due to the presence of chromium as a trace element. Chromium replaces some of the aluminum in the crystal structure, altering the way the stone absorbs and reflects light. The concentration and distribution of chromium determine the intensity and purity of the color change.
Alexandrite was first discovered in the Ural Mountains of Russia in the 19th century. Due to its rarity and beauty, it quickly became a prized gemstone among Russian nobles. Today, alexandrite is also found in Brazil, India, and Sri Lanka, although the most valuable specimens are still rare.
Alexandrite has a Mohs hardness of 8.5, making it relatively durable and suitable for use in jewelry. However, because of its rarity and unique color-changing properties, high-quality alexandrite is highly valuable and sought after by collectors and gemstone enthusiasts.
Gemological Properties
| Gemstone | Color | Luster | Hardness (Mohs) | Composition | Origin | Optical Phenomenon |
|---|---|---|---|---|---|---|
| Pearl | White, cream, pink, black | Waxy to pearly | 2.5–4.5 | Calcium carbonate (nacre) | Saltwater and freshwater mollusks | Nacreous luster |

Care and Cleaning
Due to the different hardness and composition of each of June’s birthstones, it is important to take specific care when cleaning and wearing them.
Pearl
Pearls are relatively soft (Mohs hardness 2.5–4.5) and can be easily damaged by harsh chemicals, heat, and friction. They should be cleaned with a soft, damp cloth and mild soap. Avoid exposing pearls to perfumes, lotions, and acidic substances, as these can dull their luster and damage the nacre.
Store pearls separately from other gemstones to prevent scratches, and avoid exposing them to extreme temperatures or prolonged dryness, as this can cause them to crack or become brittle.
Moonstone
Moonstone has a moderate hardness (Mohs 6–6.5), making it more durable than pearls but still vulnerable to scratches and damage. It should be cleaned with a soft cloth and mild soap, and should be kept away from harsh chemicals and abrasive materials.
Because moonstone is a feldspar gemstone, it is also sensitive to heat and light. Prolonged exposure to direct sunlight or artificial light can cause it to fade or lose its luster. Store moonstone in a cool, dark place, and avoid wearing it during activities that may subject it to impact or friction.
Alexandrite
Alexandrite has a high hardness (Mohs 8.5), making it suitable for daily wear and less vulnerable to scratches. However, its color-changing properties are sensitive to the type and intensity of light it is exposed to. To preserve its color-changing effect, avoid exposing alexandrite to extreme heat or prolonged exposure to direct sunlight.
Clean alexandrite with a soft cloth and mild soap, and avoid using ultrasonic cleaners or steamers, as these can damage the stone or its setting. Store alexandrite separately from other gemstones to prevent scratches.
