For those born on June 28, the birthstone is a unique combination of two remarkable gems: pearl and alexandrite. These gemstones are not only prized for their beauty but also for their rich history, symbolic meanings, and the rare qualities that set them apart in the world of gemology. June is one of the few months with multiple birthstones—specifically, pearl, alexandrite, and moonstone—and June 28 is particularly special because it is associated with both pearl and alexandrite.
This article delves into the properties, origins, symbolism, and care of these two extraordinary gemstones. Through an expert lens, we explore how they are formed, where they are found, and why they continue to capture the imagination of gemstone lovers and collectors alike.
The Dual Significance of June 28
June 28 is a unique day in the birthstone calendar, as it is one of the few dates associated with two distinct gemstones: pearl and alexandrite. This dual association reflects the rich diversity and historical significance of June's birthstones.
Pearl is the classic June birthstone and is deeply connected to the sea. It is formed within mollusks when an irritant enters the shell and the mollusk coats it with layers of nacre. Pearls are not only beautiful but also carry a long legacy of meaning, often symbolizing purity, wisdom, and emotional balance.
Alexandrite, on the other hand, is a relatively modern gemstone, first discovered in the 19th century. It is known for its color-changing property, appearing green in daylight and red or purple under incandescent light. This dramatic transformation is due to a phenomenon called pleochroism, making alexandrite one of the most fascinating and rare gemstones in the world.
Together, pearl and alexandrite represent the duality of June 28: the soft, serene elegance of pearl and the vibrant, dynamic allure of alexandrite. These two gems offer a perfect balance of symbolism and beauty for those born on this date.
Historical Significance and Cultural Lore
Pearl: The Gem of the Sea
Pearls have a long and storied history, spanning cultures and centuries. In ancient times, they were considered symbols of purity and wisdom. In South Asia, pearls were believed to be "dewdrops from heaven" that fell into the sea and were collected by shellfish under the full moon. In China, pearls were seen as symbols of longevity, power, and wealth, and were even used in traditional medicine as early as 2000 BC. Lower-grade pearls were ground into powders and used in remedies for various ailments.
In Europe, pearls were not only admired for their beauty but also for their medicinal properties. During the 17th century, they were used in apothecary treatments and were believed to cure diseases and even insanity. Pearls were also worn by royalty and the elite as symbols of status and elegance.
In India, pearls were so highly valued that warriors used them to decorate their swords, symbolizing the sorrow and tears that a sword might bring. This historical reverence for pearls has carried into modern times, where they continue to be cherished as symbols of innocence, purity, and emotional balance.
Alexandrite: The Color-Changing Wonder
Alexandrite is a relatively young gemstone, first discovered in the 19th century in Russia’s Ural Mountains. It was named after Czar Alexander II and quickly became a symbol of royalty and fortune. The color-changing property of alexandrite is due to the presence of chromium, which causes the gemstone to appear green in daylight and red or purple under incandescent light.
This magical transformation has led to many metaphysical beliefs surrounding alexandrite. Some cultures believe that the gemstone enhances intuition, psychic abilities, and mental clarity, making it a powerful stone for those who seek spiritual or emotional growth. Others view it as a stone of balance and harmony, helping to align the physical and spiritual aspects of a person’s life.
Alexandrite also carries the energy of transformation and adaptability, making it an ideal birthstone for those born on June 28, who are said to be deeply connected to its stabilizing and protective qualities.
Geological Formation and Sources
Pearl: A Living Gem
Unlike most gemstones, which are formed through geological processes over millions of years, pearls are organic gems that form within mollusks. The process begins when an irritant, such as a grain of sand, enters the shell of a mollusk. In response, the mollusk coats the irritant with layers of nacre, a substance composed mainly of calcium carbonate and a protein called conchiolin.
Over time, the nacre layers build up, forming a smooth, lustrous pearl. The luster and color of the pearl depend on the species of mollusk, the water conditions, and the presence of trace minerals.
There are two main types of pearls:
- Natural pearls, which form without human intervention, are extremely rare and often irregular in shape.
- Cultured pearls, which are nucleated by humans in pearl farms, are more common and can be produced in a variety of colors and shapes.
The most well-known types of pearls include:
- Akoya pearls, known for their high luster and round shape, often with a white or rose overtone.
- Freshwater pearls, which are produced in freshwater mussels and are known for their fancier colors and irregular shapes.
- South Sea pearls, found in Australia and Indonesia, which are large and have a silky, golden luster.
- Tahitian pearls, from French Polynesia, which are known for their dark colors and iridescence.
Alexandrite: A Rare Mineral with a Unique Property
Alexandrite is a rare and precious variety of chrysoberyl, a mineral that is hard and durable, with a Mohs hardness of 8.5, making it suitable for everyday wear in jewelry. It is primarily composed of aluminum and beryllium, with chromium or vanadium responsible for its color-changing effect.
The most prized alexandrite exhibits a vivid green in daylight and a deep red or purple under incandescent light. This color change is due to pleochroism, a property that allows the gemstone to reflect different colors depending on the angle of light and the viewer’s perspective.
Alexandrite is rare and highly valued, especially in its natural form. The original deposits in the Ural Mountains have long been exhausted, and today, alexandrite is primarily found in Brazil, Sri Lanka, and Madagascar. These regions produce stones with varying degrees of color change and clarity, with the best specimens being those with a strong and dramatic shift in color.
Gemological Properties
Pearl: The Organic Gem
Pearls are unique in the gem world because they are organic, meaning they are formed within living organisms. Their physical properties include:
- Hardness: 2.5–4.5 on the Mohs scale, which is relatively soft compared to other gemstones.
- Luster: Waxy to silky, known as pearlescence, which is caused by the refraction of light through multiple layers of nacre.
- Color: Pearls come in a wide range of colors, including white, cream, pink, black, and even iridescent colors.
- Transparency: Most pearls are opaque, though some can have semi-transparent or translucent qualities.
- Origin: Natural pearls are rare and often irregular in shape, while cultured pearls are more uniform and available in various colors and sizes.
Due to their softness and sensitivity to acids and chemicals, pearls require gentle care and should be stored separately from harder gemstones to avoid scratches.
Alexandrite: The Color-Changing Gem
Alexandrite is a rare and precious gemstone with the following key properties:
- Hardness: 8.5 on the Mohs scale, making it very durable and suitable for jewelry.
- Color: It is best known for its color-changing property, appearing green in daylight and red or purple under incandescent light.
- Luster: Vitreous, or glassy.
- Refractive Index: 1.74–1.76, which gives it a sparkling and lively appearance.
- Chemical Composition: Aluminum and beryllium, with chromium or vanadium responsible for the color change.
- Origin: Brazil, Sri Lanka, and Madagascar are the main sources of natural alexandrite today.
The rarity and beauty of alexandrite make it one of the most sought-after gemstones, especially among collectors and connoisseurs.

Care and Cleaning
Caring for Pearl Jewelry
Due to their organic nature and softness, pearls require special care to maintain their luster and longevity. Here are some essential tips for caring for pearl jewelry:
- Avoid harsh chemicals: Pearls are sensitive to acids, perfumes, and lotions, so it's best to remove pearl jewelry before applying any products.
- Clean gently: To clean pearls, use a soft, damp cloth. Avoid using ultrasonic cleaners or steamers, as they can damage the nacre.
- Store separately: To prevent scratches, store pearls in a soft pouch or individual compartment, away from hard gemstones like diamonds or sapphires.
