June, a month of blooming flowers and sun-drenched days, is uniquely represented by three birthstones: pearl, moonstone, and alexandrite. For those born on June 19th, the birthstone is a combination of pearl and alexandrite—two gemstones with rich histories, distinct gemological properties, and profound symbolic meanings. This article explores the allure of these two gemstones, their geological origins, their cultural significance, and their role in jewelry and metaphysical traditions.
Introduction
For individuals born on June 19th, the birthstone is a dual designation: pearl and alexandrite. Pearl, a symbol of purity and wisdom, is formed within mollusks through a natural alchemical process. Alexandrite, on the other hand, is a rare and enigmatic gemstone known for its color-changing properties, appearing green in daylight and ruby-like under incandescent light. Both stones are linked to themes of transformation, spiritual balance, and prosperity.
This article delves into the historical, geological, and metaphysical aspects of these two gemstones. We will explore how alexandrite was discovered and named, the conditions under which it forms, and its unique optical properties. For pearl, we will examine its natural formation process, its cultural significance in ancient and modern times, and its enduring appeal in jewelry. Additionally, we will discuss how these stones are used in jewelry, their care requirements, and the beliefs associated with them in different cultures.
Historical Significance and Lore
The Discovery and Legacy of Alexandrite
Alexandrite, the most modern of June’s birthstones, is named after Tsar Alexander II of Russia, who was ruling at the time of its discovery in the early 19th century. The gemstone was first found in the Ural Mountains of Russia and was initially believed to be a form of emerald. It was not until further study that its unique color-changing properties were recognized. The phenomenon, known as pleochroism, allows alexandrite to appear green in daylight and ruby-like under incandescent light. This dramatic shift in hue has made alexandrite a symbol of transformation and adaptability.
The discovery of alexandrite was celebrated as a sign of good fortune, and it quickly became a favorite among Russian nobility. The stone was associated with the power of the Tsar and the promise of prosperity. Over time, alexandrite gained international recognition and is now considered one of the most valuable and sought-after gemstones in the world.
Pearls: The Timeless Symbol of Purity
Pearls have been cherished for thousands of years, with evidence of their use in ancient civilizations dating back to around 2000 BCE. In ancient China, pearls were believed to bring wisdom and longevity. In ancient Rome, they were considered a symbol of beauty and were often worn by the elite. During the Renaissance, pearls became a staple in European royal courts, adorning the necks of queens and empresses.
The most famous historical figure associated with pearls is Cleopatra, who famously dissolved a pearl into vinegar and drank it to prove her wealth. This anecdote highlights the immense value placed on pearls in ancient times. In the 18th and 19th centuries, pearls became even more popular, especially in the form of simple, elegant jewelry worn by women of all social classes.
In modern times, pearls continue to symbolize elegance and sophistication. Their association with purity and innocence has made them a popular choice for bridal jewelry, and their timeless appeal ensures that they remain a staple in fine jewelry collections.
Geological Formation and Sources
Alexandrite: A Rare and Unique Gemstone
Alexandrite is a variety of the mineral chrysoberyl, which is composed of beryllium aluminum oxide (BeAl₂O₄). The color-changing property of alexandrite is due to the presence of trace amounts of chromium (Cr³⁺) in its crystal lattice. In daylight, the chromium ions absorb light in the blue and yellow regions of the spectrum, giving the stone its greenish hue. Under incandescent light, which has more red wavelengths, the stone absorbs the green and transmits the red, resulting in a ruby-like color.
Alexandrite is typically found in metamorphic rocks, particularly in regions where beryllium-rich pegmatites have undergone high-pressure and high-temperature transformations. The most significant historical sources of alexandrite were the Ural Mountains in Russia. However, due to depletion of these deposits, alexandrite is now more commonly found in Brazil, Sri Lanka, and Madagascar. These locations have produced stones with varying degrees of color change and clarity.
The rarity of alexandrite, combined with its unique optical properties, makes it one of the most valuable gemstones in the world. High-quality alexandrite, especially those with a strong color change and high transparency, can command prices comparable to those of fine emeralds and rubies.
Pearl Formation: Nature’s Alchemy
Unlike alexandrite, which is a mineral formed in the earth’s crust, pearls are organic gemstones formed within the soft tissue of mollusks such as oysters, mussels, and abalone. The process begins when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk secretes layers of nacre, a combination of calcium carbonate and conchiolin, to coat the irritant and protect itself. Over time, these layers build up to form a pearl.
The composition of nacre is what gives pearls their characteristic luster and iridescence. Nacre is made up of microscopic platelets of aragonite (a form of calcium carbonate) arranged in layers, with organic material binding them together. This layered structure allows pearls to reflect light in a way that creates their signature soft, glowing appearance.
Most pearls are cultivated in controlled environments, particularly in freshwater and saltwater pearl farms. Cultured pearls are not man-made but are pearls that have been encouraged to form through human intervention. The most famous sources of natural and cultured pearls include the waters of the Persian Gulf, Japan, China, and the South Sea regions of Australia and Indonesia.
Gemological Properties
Alexandrite: A Stone of Transformation
Alexandrite is one of the few gemstones that exhibits a dramatic color change under different lighting conditions. This phenomenon, known as pleochroism, is a result of the way light interacts with the chromium ions in the crystal structure. In daylight, the stone appears green to bluish-green, while under incandescent light, it shifts to a deep red or purplish-red color. This unique property makes alexandrite one of the most visually striking and valuable gemstones in the world.
The hardness of alexandrite is 8.5 on the Mohs scale, making it a relatively durable stone that can withstand normal wear in jewelry. Its refractive index ranges from 1.746 to 1.755, and it has a specific gravity of approximately 3.73. These properties contribute to its brilliance and luster when cut and polished.
Alexandrite is typically transparent to translucent, with inclusions that can range from visible to microscopic. The most highly valued alexandrite is free of visible inclusions and exhibits a strong color change. Stones with a strong green-to-red shift and high transparency are considered the finest quality.
Pearl: Organic Beauty with Unique Characteristics
Pearls are unique among gemstones because they are formed by living organisms. Unlike minerals and other inorganic gemstones, pearls are organic, meaning they are composed of biological materials. The primary component of pearls is nacre, which is made up of aragonite (a form of calcium carbonate) and conchiolin, a protein secreted by the mollusk.
Pearls have a hardness of 2.5 to 4.5 on the Mohs scale, which makes them relatively soft compared to other gemstones. This softness means that pearls require careful handling and are not suitable for everyday wear in certain types of jewelry. The luster of pearls is one of their most distinguishing features, with high-quality pearls displaying a deep, iridescent glow.
Pearls come in a wide range of colors, including white, cream, pink, lavender, black, and even green. The color of a pearl depends on the species of mollusk that formed it, as well as the environment in which it was cultivated. The most popular and valuable pearls are white or cream-colored, with a smooth surface and a strong luster.
The size, shape, and surface quality of a pearl also affect its value. Round pearls are the most desirable, followed by near-round, oval, and baroque shapes. Surface quality is assessed based on the presence of blemishes such as pits, ridges, and spots. High-quality pearls have a smooth, unblemished surface and a consistent luster.
Symbolism and Metaphysical Beliefs
Alexandrite: A Stone of Adaptability and Transformation
In metaphysical traditions, alexandrite is believed to promote adaptability, balance, and transformation.

Wearing alexandrite is thought to help individuals navigate life’s changes with grace and resilience.
Alexandrite is also associated with spiritual awakening and emotional clarity. It is believed to enhance intuition and help individuals connect with their higher selves. Some believe that alexandrite can help in overcoming fear and anxiety, allowing the wearer to embrace new opportunities with confidence.
In some cultures, alexandrite is considered a stone of good fortune and prosperity. It is believed to attract wealth and success, making it a popular choice for those seeking to enhance their financial situation or career.
Pearl: A Stone of Purity, Wisdom, and Feminine Energy
Pearls have long been associated with purity, innocence, and feminine energy. In many cultures, pearls are believed to promote inner peace, emotional balance, and spiritual growth. They are often used in meditation and healing practices to enhance intuition and emotional clarity.
In ancient Chinese culture, pearls were considered symbols of wisdom and longevity. They were believed to bring protection and good fortune, and were often used in rituals and ceremonies. In ancient Rome, pearls were associated with Venus, the goddess of love and beauty, and were worn by women to enhance their charm and allure.
In modern metaphysical practices, pearls are believed to help in the release of negative emotions such as anger, fear, and sadness. They are also thought to enhance compassion, empathy, and understanding, making them a valuable tool for those seeking to improve their relationships and emotional well-being.
Care and Cleaning
Caring for Alexandrite
Due to its high hardness and durability, alexandrite is suitable for everyday wear in most types of jewelry. However, because of its pleochroism, it is important to store alexandrite in a dark place when not being worn to prevent fading or discoloration. Avoid exposing alexandrite to prolonged sunlight or high temperatures, as this can affect its color change properties.
To clean alexandrite, use a mild detergent and warm water. Gently scrub the stone with a soft brush, and then rinse it thoroughly and dry it with a soft cloth. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone or affect its color change.
Caring for Pearl
Pearls require special care due to their softness and organic nature. They are sensitive to harsh chemicals, including household cleaners, perfumes, and lotions. It is best to apply these products before putting on pearl jewelry to avoid direct contact with the pearls.
To clean pearls, use a soft, damp cloth and gently wipe the surface. Avoid using harsh detergents or abrasive cleaners, as these can damage the nacre and reduce the luster. Never use ultrasonic cleaners or steam cleaners on pearls, as the heat and vibrations can cause the nacre to flake or the thread to break in stringed pearls.
When storing pearls, keep them in a soft pouch or a separate compartment to prevent scratches. Avoid storing pearls in an airtight container for long periods, as they need to breathe and are sensitive to changes in humidity.
