June holds a unique place in the world of birthstones, as it is the only month officially associated with three distinct gemstones: pearl, moonstone, and alexandrite. Each of these stones carries its own set of historical significance, symbolic meaning, and gemological properties. Together, they represent the diversity of June’s character, offering a range of aesthetic and emotional resonance to those born in this month.
This article provides a detailed exploration of the June birthstones, including their historical origins, geological properties, cultural symbolism, and practical care tips. The information presented is drawn from authoritative and widely recognized sources, ensuring a factual and comprehensive overview of each gemstone.
Historical Origins and Cultural Significance
The tradition of assigning gemstones to specific months dates back centuries, with one of the earliest recorded references being the Breastplate of Aaron in the Hebrew Bible. This ceremonial garment featured twelve gemstones, each representing one of the tribes of Israel. However, the modern concept of birthstones evolved over time, influenced by religious, cultural, and commercial practices.
June is among the few months with three official birthstones, a distinction that reflects both historical continuity and modern adaptation. The inclusion of three stones for a single month was driven by the need to incorporate gems that held cultural or symbolic significance, even when their availability was limited.
Pearl: The Ancient June Birthstone
Pearl has been associated with June since antiquity. In ancient Rome, pearls were linked to Venus, the goddess of love and beauty, who was believed to have been born in June. Pearls were also highly valued by Chinese and Japanese cultures for their purity, wisdom, and elegance. The organic nature of pearls, formed within the soft tissue of mollusks, made them a symbol of inner beauty, serenity, and longevity.
In the 19th and 20th centuries, pearls became a staple of high fashion, especially among European royalty. Their soft, luminous appearance made them a symbol of refinement and grace, and they were often worn as a sign of status and sophistication.
Moonstone: The Traditional June Birthstone
Moonstone became a recognized birthstone for June in 1912, when it was added to the list of traditional birthstones. Its ethereal glow, known as adularescence, is caused by the diffraction of light within the stone's layers. This optical effect gives moonstone a soft, shimmering sheen, reminiscent of moonlight on water.
Moonstone has long been associated with lunar energy and emotional balance. In ancient times, it was believed to be formed from moonbeams trapped within the Earth. It was also thought to protect travelers and promote love, fertility, and good fortune. In modern times, moonstone is often worn to enhance intuition and emotional harmony.
Alexandrite: The Modern June Birthstone
Alexandrite is the most recent addition to the June birthstone lineup, having been officially recognized in 1950. This rare gemstone is known for its remarkable color-changing property, appearing green in daylight and red under incandescent light. It was discovered in Russia in the 19th century and was named after Tsar Alexander II.
Alexandrite quickly gained a reputation as a stone of transformation and good fortune. In gemological circles, it is often referred to as the "emerald by day and ruby by night" due to its dual-color appearance. Its rarity and unique properties make it a highly prized gemstone, often reserved for special collections and fine jewelry.
The inclusion of alexandrite in the June birthstone list reflects the evolving nature of birthstone traditions. As gemology and jewelry design advanced, there was a growing interest in incorporating rare and unique gemstones that carried both aesthetic and symbolic value.
Geological Formation and Sources
Each of June’s birthstones is formed through distinct geological processes and can be found in various parts of the world. Understanding their formation and sources provides insight into their rarity, beauty, and availability.
Pearl
Pearls are formed inside mollusks such as oysters, mussels, and clams. When an irritant, such as a grain of sand, enters the mollusk’s shell, it secretes layers of nacre (also known as mother-of-pearl) to coat the irritant. Over time, these layers harden into a smooth, rounded pearl.
Cultured pearls, which are now the majority of pearls on the market, are created through human intervention. A small bead or piece of mantle tissue is inserted into the mollusk, which then coats it with nacre. This process can take several years before the pearl is ready to be harvested.
Sources of pearls include:
- Akoya pearls: Cultivated in Japan and China, known for their round shape and luster.
- South Sea pearls: Found in Australia and Indonesia, often larger and with a thicker nacre layer.
- Freshwater pearls: Produced in China and the United States, available in a wide range of shapes and colors.
Moonstone
Moonstone is a type of feldspar mineral, specifically a member of the orthoclase and albite feldspar group. Its characteristic adularescence is caused by the intergrowth of these two feldspar minerals at a microscopic level. When light passes through the stone, it is reflected off the thin layers of feldspar, creating a soft, glowing effect.
Moonstone is found in granite pegmatites and metamorphic rocks, with the most prized specimens coming from Sri Lanka, India, and Madagascar. Sri Lankan moonstone, in particular, is known for its bluish sheen, which is considered the highest quality.
Alexandrite
Alexandrite is a rare chrysoberyl gemstone that contains trace amounts of chromium, which gives it its color-changing properties. It is formed in metamorphic rocks under high heat and pressure. The chromium absorbs certain wavelengths of light, causing the stone to appear green in daylight and red in incandescent light.
The original source of alexandrite was the Ural Mountains in Russia, but most of the world’s supply now comes from Brazil, India, and Madagascar. High-quality alexandrite with a strong color change is extremely rare, making it one of the most valuable and sought-after gemstones in the world.
Gemological Properties
Understanding the physical and optical properties of each birthstone is essential for both gemologists and jewelry enthusiasts. These properties determine how the gemstone is cut, worn, and valued in the market.
Pearl
| Property | Description |
|---|---|
| Hardness | 2.5–4.5 on the Mohs scale |
| Color | White, cream, pink, black, and other hues |
| Luster | Nacreous (pearly) |
| Refractive Index | 1.53–1.68 |
| Cleavage | None |
| Specific Gravity | 1.3–1.9 |
| Transparency | Translucent to opaque |
| Composition | Calcium carbonate (CaCO₃), water, and organic material |
Pearls are relatively soft and require careful handling to avoid scratches. They are best cleaned with a soft cloth and warm water and should not be exposed to harsh chemicals or extreme temperatures.

Alexandrite: Transformation and Good Fortune
Alexandrite is often called the "stone of transformation" due to its color-changing properties. In gemological folklore, it is believed to bring good luck, personal growth, and positive change. It was once thought to be a magical gemstone that could turn emerald green into ruby red, symbolizing the transition from youth to maturity.
In modern metaphysical practices, alexandrite is used to support personal transformation, adaptability, and emotional resilience. It is also believed to enhance creativity, intuition, and spiritual insight, making it a powerful stone for those undergoing significant life changes.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of June’s birthstones. Each gemstone has unique requirements due to its hardness, cleavage, and sensitivity to chemicals and light.
Pearl Care
Pearls are delicate and require gentle handling. They should be cleaned with a soft cloth and lukewarm water. Avoid using harsh chemicals, ultrasonic cleaners, or steamers, as these can damage the nacre. Pearls should be stored separately in a soft pouch or cloth to prevent scratches.
Moonstone Care
Moonstone is relatively hard but has perfect cleavage, so it should be handled with care to avoid chipping. It can be cleaned with warm water and a soft brush, but avoid exposure to extreme temperatures or direct sunlight, as this can dull its luster. Moonstone should also be stored separately from harder gemstones.
Alexandrite Care
Alexandrite is very durable and suitable for everyday wear. It can be cleaned with warm water and a soft cloth. Avoid exposing it to extreme heat or light, as this can affect its color-changing properties. Alexandrite can be cleaned with ultrasonic cleaners, but it is best to follow the manufacturer’s recommendations.
