History and Lore
The Ancient Significance of Pearl
Pearls have long been revered for their beauty and symbolism. The June birthstone of pearl is deeply rooted in ancient traditions, with its association with purity, faithfulness, and wisdom. In many cultures, pearls were considered symbols of the moon and water, often linked to femininity, serenity, and inner calm.
Historically, royalty and nobility often wore pearls to signify their high status and pure lineage. This tradition continues today, with pearls being a popular choice for wedding jewelry and formal wear. The soft, smooth appearance of pearls has also led to their association with harmony and emotional balance, making them a favored gemstone for those seeking peace and clarity in their lives.
Moonstone and the Mystical
Moonstone, the second June birthstone, has a more mystical and enigmatic history. Known for its iridescent sheen, moonstone was believed in ancient times to be formed from moonlight. The Greeks and Romans associated it with love and fertility, while in India, it was considered a sacred stone tied to the moon goddess, Chandra.
In the 19th century, moonstone gained popularity in Europe as a symbol of protection and intuition. Its shimmering, otherworldly appearance made it a favorite in Victorian-era jewelry, often set in silver and used in romantic and sentimental pieces. Today, moonstone is seen as a stone of inner calm and emotional balance, echoing its ancient roots in spirituality and mysticism.
Alexandrite: The Modern Marvel
Alexandrite, the most recently added of June's birthstones, was discovered in the 19th century in Russia and quickly became a gem of great interest due to its remarkable color change. Known as the "emerald by day, ruby by night," alexandrite displays a green or bluish-green hue in daylight and a deep red or purplish tone under incandescent light. This unique property, known as pleochroism, makes it one of the most captivating gemstones in the world.
The discovery of alexandrite coincided with the birthday of Czar Alexander II of Russia, after whom it was named. This connection to royalty and its rare color-changing effect contributed to its status as a symbol of transformation and duality. Alexandrite has since become a highly prized gem, especially in modern jewelry, where it is valued both for its beauty and its rarity.
Geological Formation and Sources
Pearls: The Only Organic Gemstone
Pearls are the only gemstones formed within a living organism—specifically, mollusks such as oysters, clams, and mussels. The formation process begins when a foreign object, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk coats the irritant with layers of nacre, a substance composed of calcium carbonate and conchiolin. Over time, these layers build up to form a pearl.
Natural pearls are extremely rare, as they occur spontaneously without human intervention. Most pearls available today are cultured pearls, which are formed when a piece of shell or a bead is intentionally implanted into a mollusk to stimulate pearl formation. This method was developed in the 20th century and has made pearls more widely available and affordable.
Cultured pearls are produced in both saltwater and freshwater environments. Saltwater pearls, such as those from Akoya oysters in Japan, South Sea oysters in Australia, and freshwater pearls from China, are known for their round shape and lustrous finish. Freshwater pearls, on the other hand, can be found in a variety of shapes and colors, including white, pink, black, and even multicolored.
Moonstone: A Fanciful Feldspar
Moonstone is a type of orthoclase feldspar that exhibits a phenomenon called adularescence, a soft, glowing light that appears to float just beneath the surface. This effect is caused by the layered structure of the mineral, which reflects light in a way that creates a shimmering, almost ethereal appearance.
Moonstone is primarily found in India, Sri Lanka, and the United States. The Indian moonstone, in particular, is highly prized for its strong, blue-white sheen and is often used in fine jewelry. Sri Lankan moonstone is also highly valued and is known for its large, clear crystals.
Moonstone is relatively soft compared to other gemstones, with a Mohs hardness of 6 to 6.5, making it prone to scratches and damage. As a result, it is often set in protective settings and worn with care to preserve its delicate beauty.
Alexandrite: A Rare Chrysoberyl
Alexandrite is a rare variety of the mineral chrysoberyl, known for its color-changing property. This effect is due to the presence of chromium or vanadium ions within the crystal structure. Under daylight or fluorescent light, the stone appears green or bluish-green, while under incandescent light, it shifts to a deep red or purplish hue.
The most famous alexandrite deposits were originally found in Russia's Ural Mountains, but the supply from there is now nearly depleted. Today, alexandrite is also found in Brazil, India, and Madagascar, though the Russian material is still considered the most valuable due to its superior color change and clarity.
Alexandrite is a hard gemstone, with a Mohs hardness of 8.5, which makes it relatively durable for jewelry use. However, due to its rarity and unique color change, alexandrite is one of the most expensive birthstones and is often reserved for special or heirloom pieces.
Gemological Properties
| Gemstone | Color | Hardness (Mohs) | Luster | Transparency | Composition |
|---|---|---|---|---|---|
| Pearl | White, pink, black, blue | 2.5–4.5 | Waxy to pearly | Translucent | Calcium carbonate, conchiolin |
| Moonstone | White, gray, blue | 6–6.5 | Vitreous, with adularescence | Translucent | Orthoclase feldspar |
| Alexandrite | Green, red, purplish | 8.5 | Vitreous | Transparent | Beryllium-aluminum oxide with chromium or vanadium |
Pearl
Pearls are unique in that they are organic gemstones, formed within the bodies of mollusks. Their color range includes white, pink, black, and blue, with the most desirable being those with a creamy white color and a subtle rainbow-like sheen. The luster of a pearl is waxy or pearly, and its hardness is relatively low, ranging from 2.5 to 4.5 on the Mohs scale. This means that pearls are susceptible to scratches and damage from harsh chemicals or abrasive materials.
Moonstone
Moonstone is a fanciful feldspar known for its iridescent sheen, called adularescence. The stone is usually white or gray, with a bluish or silver sheen that moves across the surface. Its hardness is 6 to 6.5, making it more durable than pearls but still relatively soft. Moonstone is often cut in cabochon form to enhance its shimmering effect.
Alexandrite
Alexandrite is a rare and valuable gemstone with a hardness of 8.5, making it one of the harder gemstones. Its transparency is high, and it is often cut in brilliant or mixed cuts to maximize the color change effect. The most prized alexandrites display a vivid green to bluish-green in daylight and a deep red or purplish hue in incandescent light. This color-changing property, known as pleochroism, is what makes alexandrite so unique and valuable.
Symbolism and Metaphysical Beliefs
Pearl: Purity, Peace, and Wisdom
Pearls have long been associated with purity, peace, and wisdom. In many cultures, pearls were believed to have calming and healing properties, helping to soothe emotions and promote mental clarity. Ancient Greeks and Romans believed pearls to be gifts from the sea, often linked to love and fertility.
In modern metaphysical beliefs, pearls are thought to help balance emotions, promote calmness, and enhance intuition. They are also believed to attract good luck and prosperity, making them a popular choice for those seeking emotional and spiritual balance.
Moonstone: Intuition, Protection, and Feminine Energy
Moonstone is often associated with intuition, emotional balance, and feminine energy. Its iridescent sheen is believed to mirror the cycles of the moon, symbolizing change and transformation. In many traditions, moonstone is considered a stone of protection, especially for women and travelers.
Moonstone is also believed to enhance intuition and psychic abilities, making it a popular stone for meditation and spiritual practices. It is often used to calm anxiety, ease stress, and promote emotional healing, especially for those going through emotional transitions or difficult times.
Alexandrite: Transformation, Duality, and Renewal
Alexandrite is a stone of transformation and duality, symbolizing change and balance. Its color-changing property is often interpreted as a metaphor for adaptability and personal growth. In many cultures, alexandrite is believed to help individuals navigate change and find clarity in times of uncertainty.
Alexandrite is also associated with renewal and regeneration, making it a symbol of new beginnings and fresh opportunities. It is often used in jewelry as a gift, symbolizing love, commitment, and the promise of a bright future.
Care and Cleaning
Caring for Pearls
Pearls are delicate gemstones that require gentle care to maintain their luster and beauty. Due to their organic composition and low hardness, pearls can be damaged by harsh chemicals, abrasive materials, and excessive moisture.
To clean pearls, use a soft, lint-free cloth to gently polish the surface. Avoid using abrasive cleaners, ultrasonic cleaners, or steam cleaners, as these can damage the nacre. Store pearls in a soft pouch or individual compartment to prevent scratches and moisture buildup.
Avoid wearing pearls during swimming, showering, or exposure to chemicals, as this can strip the nacre and dull the luster. When not in use, pearls should be stored in a cool, dry place to prevent discoloration and degradation.
Caring for Moonstone
Moonstone is relatively soft and can be damaged by abrasive materials and harsh chemicals. To clean moonstone, use a soft cloth and mild soap with warm water. Gently wipe the stone and dry it with a clean cloth.
Avoid using ultrasonic or steam cleaners, as these can damage the delicate feldspar structure and reduce the sheen. Store moonstone in a soft pouch or jewelry box to prevent scratches and exposure to moisture.
Moonstone should not be exposed to extreme heat or cold, as this can cause cracking or discoloration. When wearing moonstone jewelry, avoid rough handling or abrasive surfaces to preserve its beauty and integrity.
Caring for Alexandrite
Alexandrite is harder than pearls and moonstone, making it more durable and easier to care for. However, due to its rare and valuable nature, it should still be handled with care.
To clean alexandrite, use a soft cloth and mild soap with warm water. Gently polish the surface and dry it with a clean cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the surface or dull the color change effect.
Alexandrite should be stored in a cool, dry place, away from extreme heat or direct sunlight, which can alter the color or reduce the clarity. When wearing alexandrite jewelry, avoid impact or pressure, as this can cause chips or fractures.
