History and Lore
Ancient Fascination with the June Birthstones
The fascination with gemstones dates back to ancient civilizations, where they were often believed to possess mystical powers and serve as conduits for divine energy. The June birthstones—pearl, moonstone, and alexandrite—each have deep historical roots that reflect their roles in various cultures.
Pearls, for instance, were considered symbols of purity and wisdom in many ancient societies. In the Middle East, it was believed that pearls were formed from the tears of angels. In ancient China, pearls were thought to be the brain of a dragon, symbolizing intelligence and power. In the Americas, Christopher Columbus and his contemporaries believed that pearls were formed from dew drops inside mollusks. These varied interpretations highlight the universal appeal and mystery of pearls across different cultures.
Moonstone, on the other hand, has long been associated with lunar deities and celestial mysticism. The Roman historian Pliny the Elder is credited with naming the gemstone moonstone due to its shimmering appearance, which he likened to the phases of the moon. In Greek and Roman mythology, moonstone was believed to be formed from moonbeams and was associated with goddesses such as Selene and Artemis. In Hindu traditions, moonstone was thought to be made from solidified moonlight and was used in rituals to promote fertility and love. In some cultures, moonstone was even considered a remedy for insomnia and sleepwalking, and it was worn as a protective charm by travelers navigating the night.
Alexandrite is the most recent addition to the June birthstone list, having been officially recognized in 1952 by the Jewelers of America. Its discovery in 1831 in the Ural Mountains of Russia was a momentous event in the history of gemology. The stone was named after Russian Tsar Alexander II, who was celebrating his coming of age on the same day the gem was first discovered. This historical coincidence led to the name Alexandrite, and the gem quickly became a symbol of good fortune and regal elegance. In Vedic astrology, the cat’s eye effect of alexandrite is believed to be connected to the moon node, further linking it to celestial influences.
Together, these three gemstones have captivated the imagination of people for centuries, and their historical associations continue to influence their cultural and symbolic significance today.
Geological Formation and Sources
Pearl: The Organic Wonder
Unlike most gemstones, pearls are organic in origin and are formed within the soft tissue of certain mollusks, primarily oysters and clams. The process of pearl formation begins when an irritant—such as a grain of sand or a small parasite—enters the mollusk’s shell or tissue. In response to the foreign material, the mollusk begins to secrete a substance called nacre, a combination of aragonite (a form of calcium carbonate) and conchiolin (an organic protein). Over time, layers of nacre build up around the irritant, forming a pearl.
There are two main types of pearls: natural and cultured. Natural pearls form without human intervention and are extremely rare. Cultured pearls, on the other hand, are the result of a process called pearl farming, in which a bead or piece of nacre is intentionally inserted into the mollusk to stimulate pearl formation. This method has made pearls more widely available and has helped sustain the global pearl industry.
Pearls can be found in both saltwater and freshwater environments. Saltwater pearls are typically produced by oysters in oceans and are known for their smooth, round shape and high luster. Notable sources of saltwater pearls include the Persian Gulf, the Indian Ocean, and the South Pacific. Freshwater pearls, on the other hand, are produced by mussels in lakes and rivers and are more varied in shape and color. China is a major producer of freshwater pearls.
Moonstone: The Feldspar with a Shimmer
Moonstone is a type of feldspar mineral that exhibits a unique optical phenomenon known as adularescence—a soft, ethereal glow that appears to float across the surface of the stone. This effect is caused by the intergrowth of two different types of feldspar within the crystal structure, which refract light in a way that creates the illusion of movement.
Moonstone is typically composed of orthoclase and albite, two potassium- and sodium-rich feldspar minerals. The alternating layers of these minerals are extremely thin, often only a few nanometers in thickness, and they scatter light as it passes through the stone. This scattering effect is what produces the characteristic shimmer known as adularescence.
Moonstone is found in various parts of the world, including India, Sri Lanka, Brazil, United States, and Madagascar. Indian moonstone, in particular, is highly prized for its strong blue sheen and is often referred to as “blue moonstone.” The most valuable moonstones are those that display a vivid, clear blue sheen when placed against a white background.
Alexandrite: The Color-Changing Gem
Alexandrite is a rare and highly valued variety of the mineral chrysoberyl, with the chemical formula BeAl₂O₄. What makes alexandrite unique is its ability to change color under different lighting conditions—a phenomenon known as color change. In daylight or fluorescent light, alexandrite appears green or greenish-blue, while under incandescent light, it shifts to a red or purplish hue.
This color change is not due to pleochroism (the ability of a gemstone to show different colors when viewed from different angles), but rather to the way the gem absorbs and reflects light. The presence of chromium in the crystal structure is responsible for the color change. Chromium absorbs certain wavelengths of light, allowing only the green and red hues to be reflected depending on the light source.
Alexandrite was first discovered in 1831 in the Ural Mountains of Russia, and it was named after Russian Tsar Alexander II. Today, alexandrite is also found in Brazil, Madagascar, and India. Brazilian alexandrite is particularly notable for its strong color change and high clarity. Due to its rarity and unique properties, alexandrite is considered one of the most valuable gemstones in the world.
Gemological Properties
Pearl: The Soft, Lustrous Gem
Pearls are unique in that they are the only gemstones that are formed by living organisms. Their hardness on the Mohs scale is relatively low, ranging from 2.5 to 4.5, which means they are easily scratched and require special care. Despite their softness, pearls are highly valued for their luster, translucency, and surface quality.
Pearls can vary in shape, from perfectly round to irregular, and in color, from classic white to rare black, pink, and even green. The luster of a pearl is a key factor in its value, with the best pearls exhibiting a deep, mirror-like surface. Other important factors include surface smoothness, nacre thickness, and origin (natural vs. cultured).
Moonstone: The Shimmering Feldspar
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, which makes it relatively durable but still prone to scratches and chips if mishandled. Its specific gravity is around 2.55 to 2.58, and it is typically translucent to opaque, with a pale white or gray coloration and a soft, milky luster.
One of the most important characteristics of moonstone is its adularescence, the soft, billowy light that seems to move across the surface of the stone. The most desirable moonstones are those that display a strong blue sheen, especially when viewed against a white background. Moonstone is also known for its double refraction, a property that causes objects viewed through the stone to appear doubled.
Alexandrite: The Rare Color-Changing Gem
Alexandrite is a hard gemstone, with a hardness of 8.5 to 9 on the Mohs scale, making it suitable for use in jewelry. It has a specific gravity of 3.71 to 3.76 and is typically transparent to translucent. The most valuable alexandrites are those that display a vivid green in daylight and a deep red or purplish hue in incandescent light.
Alexandrite's chemical formula is BeAl₂O₄, and it is a birefringent mineral, meaning it can split light into two rays. This property contributes to its pleochroism, the ability to show different colors when viewed from different angles. However, the color change in alexandrite is not due to pleochroism but rather to the absorption and reflection of light, caused by the presence of chromium in the crystal structure.
Symbolism and Metaphysical Beliefs
Pearl: A Symbol of Purity and Wisdom
Throughout history, pearls have been associated with purity, wisdom, and feminine energy. In many cultures, they are seen as symbols of innocence, chastity, and inner peace. Pearls are often used in wedding jewelry, particularly for 3rd and 30th wedding anniversaries, as they represent the enduring beauty of a lasting love.
In Vedic astrology, pearls are associated with the Moon, and they are believed to help regulate emotional balance, intuition, and compassion. Some cultures believe that wearing pearls can calm the mind, enhance communication, and attract positive energy.
Moonstone: The Stone of New Beginnings
Moonstone is often referred to as "the stone of new beginnings", and it is associated with fertility, love, and protection. In Hindu tradition, moonstone is believed to be made from solidified moonbeams, and it is used in rituals to promote fertility and harmonious relationships.
In Roman and Greek mythology, moonstone was associated with lunar deities and was believed to bring inspiration, dreams, and emotional balance. Some cultures used moonstone as a protective charm for travelers, believing that it would ward off danger and guide them safely through the night.
In modern metaphysical practices, moonstone is used to enhance intuition, emotional healing, and feminine energy. It is often worn during moon rituals, meditation, and spiritual practices to connect with the moon's energy.
Alexandrite: The Stone of Transformation
Alexandrite is a powerful stone of transformation and balance, and it is associated with personal growth, adaptability, and inner strength. In Vedic astrology, alexandrite is linked to the moon node, and it is believed to help individuals navigate life’s changes and embrace new possibilities.
The color-changing property of alexandrite is often interpreted as a symbol of duality and change, and it is used to encourage flexibility, resilience, and emotional equilibrium. Alexandrite is also associated with good fortune, success, and regal power, making it a popular gemstone for leaders, visionaries, and entrepreneurs.
Care and Cleaning
Caring for June Birthstones
Due to their different physical properties, the three June birthstones require different care and cleaning methods.
Pearls: Being soft and porous, pearls are very sensitive to abrasion, heat, humidity, and chemicals. They should be cleaned gently with a soft, damp cloth and avoided contact with perfumes, lotions, and harsh cleaning agents. Pearls should be stored separately from other jewelry to prevent scratching.
Moonstone: Moonstone has a moderate hardness but is prone to scratches and chips. It should be cleaned with mild soap and warm water, and avoided exposure to harsh chemicals. Moonstone is also sensitive to heat, so it should be stored in a cool, dry place.
Alexandrite: Alexandrite is a hard and durable gemstone, but it should still be handled with care to avoid chipping along its cleavage planes. It can be cleaned with warm, soapy water and a soft brush, and it is safe to use ultrasonic cleaners as long as the stone is free of inclusions.
