Whether you are drawn to the timeless beauty of pearls, the ethereal glow of moonstone, or the rare color-changing properties of alexandrite, June offers a diverse selection of gemstones that cater to a wide range of tastes and preferences. This article delves into the fascinating world of June's birthstones, exploring their geological properties, historical significance, cultural symbolism, and care instructions.
History and Lore
Pearl: The Timeless Classic
Pearls have long been cherished for their luminous beauty and have a storied history across various cultures. Unlike most gemstones, which are formed through geological processes deep within the Earth, pearls are created by living organisms—specifically, mollusks. Ancient Greeks believed pearls were the hardened tears of joy shed by Aphrodite, the goddess of love. In Chinese mythology, pearls were associated with dragons, symbolizing wisdom and power. Cleopatra, the Egyptian queen, famously dissolved a pearl in vinegar and drank it to demonstrate her wealth and devotion to Marc Antony.
Throughout history, pearls have been symbols of purity, transformation, and the sea. Their soft, iridescent glow has inspired poets, artists, and jewelers for centuries. Today, pearls continue to be a popular choice in jewelry, especially in classic and minimalist designs.
Moonstone: The Stone of Emotional Balance
Moonstone, with its milky white body and flashes of blue or other colors, is often associated with the divine feminine and emotional balance. This gemstone has been revered for its mystical qualities, particularly its connection to the moon. Ancient Romans and Greeks believed moonstone was formed from moonbeams, and many cultures have used it in rituals and ceremonies related to femininity, intuition, and emotional well-being.
In modern times, moonstone is often used in jewelry to promote calmness and serenity. Its gentle, shimmering appearance makes it a favorite among those who seek emotional harmony and spiritual insight.
Alexandrite: The Color-Changing Wonder
Alexandrite is a relatively modern addition to the list of June birthstones, first discovered in the 19th century in Russia. What makes alexandrite truly unique is its ability to change color under different lighting conditions. In daylight, it appears green, but under incandescent light, it shifts to a reddish hue. This phenomenon, known as the alexandrite effect, is due to the presence of chromium in the gemstone.
The discovery of alexandrite was attributed to Count Alexei Khinsky, who named the stone after Tsar Alexander II of Russia. Since its discovery, alexandrite has been prized for its rarity and beauty. It is considered a symbol of transformation and adaptability, making it a meaningful choice for those born in June.
Geological Formation and Sources
Pearl Formation
Pearls are formed inside the soft tissue of mollusks, such as oysters and mussels, when an irritant, like a grain of sand or a parasite, enters the shell. To protect itself, the mollusk secretes layers of nacre around the irritant, gradually forming a pearl. The process can take several years, and the resulting pearl's size, shape, and color depend on various factors, including the type of mollusk, water conditions, and the length of time the pearl is formed.
Cultured pearls, which are now the most common type of pearl available, are produced with human assistance. In this process, a small bead is inserted into the mollusk to stimulate nacre production. This method allows for greater control over the pearl's size and shape while still maintaining its natural qualities.
Pearls are found in various parts of the world, including the Persian Gulf, the South Sea, and freshwater regions in China and Japan. Each location produces pearls with distinct characteristics, such as color, luster, and surface quality.
Moonstone Formation
Moonstone is a type of feldspar mineral, specifically a member of the plagioclase feldspar group. It is formed when two different feldspar minerals intergrow within a rock, creating layers that reflect light in a unique way. This optical phenomenon, known as adularescence, gives moonstone its characteristic shimmer or "glow."
Moonstone is typically found in igneous and metamorphic rocks and is mined in various parts of the world, including India, Sri Lanka, Myanmar, and the United States. The most prized moonstone for jewelry comes from India, where it is known for its intense blue sheen and high quality.
Alexandrite Formation
Alexandrite is a variety of the mineral chrysoberyl, which is composed of beryllium and aluminum oxides. The color change in alexandrite is due to the presence of trace amounts of chromium. The stone is typically found in metamorphic rocks and is formed under high-temperature and high-pressure conditions.
The original source of alexandrite was in the Ural Mountains of Russia, but due to the depletion of these deposits, the stone is now primarily sourced from other regions, including Brazil, Sri Lanka, and Madagascar. Brazilian alexandrite, in particular, is known for its vibrant color change and high quality.
Gemological Properties
Pearl
Pearls are unique among gemstones because they are not formed through geological processes but rather through biological processes. Their properties include:
- Hardness: 2.5–4.5 on the Mohs scale
- Luster: Waxy to pearly
- Color: White, cream, pink, black, and other hues
- Transparency: Translucent to opaque
- Cleavage: None
- Fracture: Conchoidal
- Specific Gravity: 2.71–2.85
- Refractive Index: 1.53–1.69
Pearls are relatively soft and porous, which makes them susceptible to damage from chemicals, heat, and abrasion. Proper care is essential to maintain their luster and longevity.
Moonstone
Moonstone is a feldspar mineral with the following gemological properties:
- Hardness: 6–6.5 on the Mohs scale
- Luster: Vitreous
- Color: White, gray, yellow, and other colors with a blue sheen
- Transparency: Translucent
- Cleavage: Perfect in two directions
- Fracture: Uneven
- Specific Gravity: 2.55–2.57
- Refractive Index: 1.518–1.524
Moonstone's most notable feature is its adularescence, which is caused by the intergrowth of different feldspar minerals. This effect gives moonstone a soft, glowing appearance that is highly valued in jewelry.
Alexandrite
Alexandrite is a rare and valuable gemstone with the following properties:
- Hardness: 8.5–9 on the Mohs scale
- Luster: Vitreous
- Color: Green in daylight, red under incandescent light
- Transparency: Transparent to translucent
- Cleavage: Perfect in three directions
- Fracture: Uneven
- Specific Gravity: 3.73–3.74
- Refractive Index: 1.74–1.75
Alexandrite's color change is due to the presence of chromium, which absorbs certain wavelengths of light. This effect is most pronounced when the stone is viewed under different lighting conditions. The stone's high hardness and excellent luster make it a durable choice for jewelry.

Care and Cleaning
Pearl
Pearls require special care due to their soft and porous nature. They should be stored separately from other gemstones to prevent scratches and abrasions. Avoid exposing pearls to harsh chemicals, perfumes, and lotions, as these can damage the nacre.
To clean pearls, use a soft, damp cloth to gently wipe the surface. Do not use ultrasonic or steam cleaners, as these can cause the pearls to dry out and lose their luster. After wearing, store pearls in a soft pouch or a lined jewelry box.
Moonstone
Moonstone is relatively durable but should still be handled with care. It is sensitive to high temperatures and can be damaged by sudden changes in temperature. Store moonstone jewelry separately from harder gemstones to avoid scratches.
