June is one of the most unique months in the world of birthstones, distinguished by the fact that it officially recognizes three gemstones: pearl, moonstone, and alexandrite. Each of these gems carries a rich history, distinct gemological properties, and deep cultural and metaphysical significance. Whether you are captivated by the soft luster of pearls, the ethereal shimmer of moonstone, or the mesmerizing color transformation of alexandrite, there is a June birthstone to reflect your personal energy and aesthetic.
This article delves into the origins, properties, symbolism, and care of these three gems, drawing on historical records and modern gemological insights. We explore why June has three birthstones, how each gem was historically and culturally valued, and what makes them significant in both spiritual and decorative contexts.
History and Lore
The tradition of birthstones dates back to ancient civilizations, including the biblical Book of Exodus, which mentions the twelve stones of the High Priest's breastplate. Over time, the idea of assigning specific stones to months evolved in various cultures, with the modern concept largely shaped by the 20th century.
June's birthstones represent a blend of tradition and modernity. The pearl is the oldest and most historically significant of the three, having been revered for millennia. Ancient Greeks believed pearls were the tears of the gods, while in Chinese culture, they symbolized wisdom and purity. Pearls have long been associated with royalty and wealth, often seen in the jewelry of queens and empresses.
Moonstone, on the other hand, has long been associated with lunar deities and feminine energy. The ancient Romans believed moonstone was formed from moonbeams, and it was considered a sacred stone among the Celtic and Hindu traditions. In India, it was believed to enhance fertility and was often worn by women seeking emotional balance and intuitive clarity.
Alexandrite, the youngest of the three, was only discovered in the 19th century and quickly became a symbol of transformation and duality. Its color-changing properties were seen as magical and were interpreted as a metaphor for personal growth and adaptability.
These three stones represent a unique convergence of ancient reverence and modern mystique, making June one of the most intriguing months in the birthstone calendar.
Geological Formation and Sources
Pearl: A Living Gem
Unlike most gemstones, which are formed in the Earth’s crust over millions of years, pearls are created by living organisms—specifically mollusks such as oysters and mussels. The formation process begins when a foreign object, such as a grain of sand, enters the mollusk’s shell. To protect itself, the mollusk secretes layers of nacre (a calcium carbonate compound) around the irritant, gradually forming a lustrous pearl.
Pearls come in a variety of colors, including white, cream, pink, black, and lavender, depending on the type of mollusk and the environment in which it lives. Historically, some of the most prized pearls were sourced from the Persian Gulf and the coasts of India. Today, freshwater pearls from China and saltwater pearls from Japan, the South Sea, and the Persian Gulf are among the most notable.
Moonstone: A Silicate Enigma
Moonstone is a type of feldspar, a group of silicate minerals that make up a large portion of the Earth’s crust. It is most commonly found in granitic pegmatite deposits, often in regions with a history of volcanic activity. The characteristic shimmer of moonstone, known as adularescence, is caused by the way light interacts with layers of different feldspar minerals within the stone.
Moonstone is primarily mined in Sri Lanka, where it is considered the national gem. Other notable sources include India, Madagascar, and the United States (particularly in Georgia and New York). The finest moonstone typically exhibits a strong blue flash, known as bluish sheen, which is most vivid in translucent stones.
Alexandrite: A Rare and Enigmatic Gem
Alexandrite is a rare variety of the mineral chrysoberyl, distinguished by its ability to change color depending on the light source. In daylight, it often appears green or bluish-green, while under incandescent light, it shifts to a reddish or purplish hue. This phenomenon, known as color change, is caused by the presence of trace amounts of chromium in the crystal structure.
Alexandrite was first discovered in the Ural Mountains of Russia in the early 19th century and was named after Tsar Alexander II. Today, significant deposits are found in Brazil, India, and Madagascar, though high-quality alexandrite remains rare. The best specimens are those that exhibit a strong and dramatic color shift, as well as clarity and size.
Gemological Properties
Pearl
| Property | Details |
|---|---|
| Chemical Composition | Calcium carbonate (CaCO₃) |
| Hardness (Mohs) | 2.5–4.5 |

| Transparency | Translucent to transparent |
| Color | White, gray, with a blue sheen |
| Sources | Sri Lanka, India, Madagascar, USA |
| Treatments | Heat treatment (rare), irradiation (rare) |
Moonstone is relatively durable, but it is susceptible to damage from sudden temperature changes and harsh chemicals. Its unique shimmer is best appreciated in stones with even layers and minimal inclusions.
Alexandrite
| Property | Details |
|---|---|
| Chemical Composition | BeAl₂O₄ (Chrysoberyl) |
| Hardness (Mohs) | 8.5 |
| Luster | Vitreous |
| Specific Gravity | 3.71–3.74 |
| Transparency | Transparent to translucent |
| Color | Green in daylight, red in incandescent light |
| Sources | Brazil, India, Madagascar |

Alexandrite is a hard and durable gemstone, making it suitable for everyday wear. The best specimens are those that display a strong color change and have minimal inclusions.
Symbolism and Metaphysical Beliefs
Each of June’s birthstones is associated with distinct metaphysical and spiritual properties, making them popular choices for those seeking emotional balance, personal transformation, or creative inspiration.
Pearl: Purity and Emotional Healing
Pearls are often linked with purity, wisdom, and inner peace.
