June boasts a unique pairing of birthstones: the color-changing alexandrite and the timeless pearl. These gems, while vastly different in origin and appearance, both hold a significant place in gemological history and continue to captivate with their beauty and symbolism. This article will explore the history, properties, and significance of these June birthstones, offering insight into what makes them so cherished.
History and Lore
Alexandrite’s story begins in the Ural Mountains of Russia in the 1830s. Its discovery coincided with the future Czar Alexander II’s coming of age, and the gem was promptly named in his honor. This relatively recent discovery contributes to its enduring mystique. The gem quickly became associated with balance and transformation due to its remarkable ability to shift color depending on the light source. This characteristic led to its adoption as a symbol of harmony and adaptability. Alexandrite’s rarity further enhanced its appeal, making it a prized possession among collectors and gem enthusiasts.
Pearls, in contrast, have a history stretching back millennia. Celebrated for centuries as symbols of purity, wisdom, and timeless beauty, pearls have been found in ancient sites around the world. Their organic formation within the ocean has long connected them to the sea and imbued them with a sense of natural wonder. Throughout history, pearls have adorned royalty and been valued as objects of great prestige.
Geological Formation and Sources
Alexandrite is a variety of the mineral chrysoberyl. Its color-changing ability is due to the presence of chromium impurities within its crystal structure. The gem forms in metamorphic rocks and is relatively rare, making natural alexandrite highly sought after. While the original discoveries were made in Russia, alexandrite is now also found in Sri Lanka, East Africa, and Brazil.
Pearls are formed within oysters and other mollusks. Natural pearls are created when an irritant, such as a grain of sand, enters the shell. The mollusk then coats the irritant with layers of nacre, creating a pearl. Cultured pearls are created through a similar process, but with human intervention – a technician inserts a nucleus into the mollusk to initiate pearl formation. Pearls are sourced from both saltwater and freshwater environments, with major producing regions including Japan, Australia, the South Seas, and China.
Gemological Properties
Alexandrite is renowned for its dramatic color change. In daylight or fluorescent light, it typically appears green to bluish-green. However, under incandescent light, it shifts to red to purplish-red. This chameleon-like quality is what sets it apart from other gemstones. The intensity of the color change is a key factor in determining its value, with a more pronounced shift being highly desirable.
Pearls, unlike most gemstones, are not graded on the traditional 4Cs (color, clarity, cut, carat). Instead, their value is determined by luster, surface quality, shape, size, and color. Luster refers to the pearl’s reflective quality; high-quality pearls possess a mirror-like shine known as orient, giving them a soft inner glow. Surface quality is assessed based on the presence of blemishes. Pearls come in a variety of shapes, including round, pear, button, and baroque. Colors range from classic white and cream to more exotic shades like silver, black, and gold.
The following table summarizes key gemological properties:
| Property | Alexandrite | Pearl |
|---|---|---|
| Mineral | Chrysoberyl | Calcium Carbonate |
| Color | Green/Red (color change) | White, Cream, Black, Gold |
| Luster | Vitreous | Nacreous |
| Hardness (Mohs) | 8.5 | 2.5 - 4.5 |
| Formation | Metamorphic Rocks | Mollusks |
Symbolism and Metaphysical Beliefs
Alexandrite’s color-changing ability has led to its association with balance, adaptability, and inner growth. It is believed to promote self-awareness and encourage positive transformation. The gem is also thought to bring good luck and fortune.
Pearls have long been symbols of purity, innocence, and wisdom. They are often associated with femininity and are believed to promote emotional balance and inner peace. In some cultures, pearls are considered symbols of tears and are associated with mourning, while in others, they represent joy and celebration.
Care and Cleaning
Alexandrite, with a Mohs hardness of 8.5, is a relatively durable gemstone. However, it is still susceptible to scratches and damage from harsh chemicals. Cleaning alexandrite jewelry can be done with warm, soapy water and a soft brush. Avoid ultrasonic cleaners and steam cleaners, as these can damage the gem.
Pearls are much softer than alexandrite, with a hardness of only 2.5 to 4.5. They are easily scratched and damaged by chemicals, cosmetics, and even perspiration. Pearls should be cleaned with a soft, damp cloth after each wearing. Avoid harsh chemicals, ultrasonic cleaners, and abrasive materials. It is also recommended to have pearls restrung periodically, as the silk thread can weaken over time.

Alexandrite is often featured as a center stone in pendants and rings, showcasing its captivating color change. Pearls are commonly used in classic pearl strands, earrings, and pendants.

Lab-created alexandrite provides a more accessible option for those seeking the gem’s unique beauty.
