June stands apart in the world of birthstones not just for its association with summer, but for the rare distinction of being linked to three gemstones: pearl, moonstone, and alexandrite. This unique triad offers a rich tapestry of meaning, history, and beauty, reflecting both ancient traditions and modern adaptations. Each of these stones carries its own set of symbolic meanings, geological properties, and cultural significance. This article delves into the origins, characteristics, and symbolism of June’s birthstones, offering a comprehensive guide for gemstone enthusiasts, jewelry connoisseurs, and those seeking a meaningful gift.
Introduction
June is the only month in the birthstone calendar with three officially recognized gemstones: pearl, moonstone, and alexandrite. This triad was not always the case—originally, only pearl was considered the birthstone for June. Over time, as the availability and popularity of gemstones changed, moonstone and alexandrite were added to the list. This evolution reflects both practical concerns—such as the rarity and cost of natural pearls—and a growing appreciation for the unique qualities of these other gems.
Each of these stones has distinct physical and symbolic properties. Pearls are organic gems formed in mollusks and have long been associated with purity and wisdom. Moonstone, a type of feldspar, is known for its ethereal glow and is often linked to intuition and emotional balance. Alexandrite, the rarest of the three, is prized for its rare color-changing properties and is associated with transformation and fortune.
This article explores the history, gemological properties, cultural significance, and care instructions for each of these three June birthstones. It also discusses why June has three birthstones and what makes this triad so special in the world of gemstones.
History and Lore
The Origins of Birthstone Traditions
The tradition of associating gemstones with specific months has ancient roots. One of the earliest recorded references is found in the Breastplate of Aaron, a ceremonial garment described in the Hebrew Bible (Exodus 28:15-30), which contained twelve gemstones representing the twelve tribes of Israel. While this early system did not directly correspond to the modern birthstone calendar, it laid the foundation for later associations between gemstones and months.
The modern concept of birthstones began to take shape in the early 20th century. In 1912, the American National Retail Jewelers Association (now Jewelers of America) published a standardized list of birthstones for each month. This list was revised in 1952 and again in 2002 to reflect changes in gemstone availability and cultural preferences.
June was one of the months that saw significant changes during these revisions. Originally, pearl was the sole birthstone for June. However, as natural pearls became rarer and more expensive, and as the jewelry industry sought to offer more options to consumers, moonstone and alexandrite were added to the list in the mid-20th century. This addition reflects a blend of tradition and modernity, allowing June-born individuals to choose a gemstone that best suits their style, budget, and personal meaning.
Cultural Significance of June Birthstones
Each of the three June birthstones has a unique cultural and symbolic background:
Pearl: Known as the oldest traditional June birthstone, pearl is often associated with purity, wisdom, and serenity. In many cultures, pearls are believed to promote calmness and inner peace. In ancient China, pearls were considered a symbol of longevity and immortality, while in the West, they have long been associated with grace and elegance.
Moonstone: This gemstone is often linked to emotional balance, intuition, and the divine feminine. In ancient India, moonstone was believed to be formed from moonbeams, and it was thought to bring good luck and protection. In modern crystal healing, moonstone is often used to support emotional stability and to enhance inner growth.
Alexandrite: The rarest of the three, alexandrite is known for its color-changing properties, shifting from green in daylight to reddish-purple in incandescent light. This unique feature has made it a symbol of transformation, adaptability, and good fortune. Alexandrite was discovered in the 19th century in Russia and was named after Tsar Alexander II. It was later added to the June birthstone list in the mid-20th century as a modern option for those seeking a more unique and luxurious gemstone.
Together, these three stones offer a rich and diverse range of meanings and histories, making June’s birthstone selection one of the most unique in the calendar.
Geological Formation and Sources
Pearl: The Organic Gem
Unlike most gemstones, which are formed through geological processes, pearls are organic gemstones formed within mollusks such as oysters and mussels. The formation of a pearl begins when a foreign particle, such as a grain of sand, enters the soft tissue of a mollusk. To protect itself, the mollusk secretes layers of nacre, a crystalline substance composed mainly of calcium carbonate and conchiolin, around the irritant. Over time, these layers build up to form a smooth, lustrous pearl.
Natural pearls are extremely rare, and most pearls available in the market today are cultured pearls, which are formed under controlled conditions. Cultured pearls are created by introducing a small bead or piece of mantle tissue into a mollusk, which then coats it with nacre. This process allows for more predictable and consistent pearl production.
Sources of pearls include various parts of the world, including:
- Freshwater pearls are primarily produced in China, the United States, and Japan.
- Saltwater pearls, such as Akoya pearls, are mostly produced in Japan and China, while South Sea pearls come from Australia and Indonesia, and Tahitian pearls are found in French Polynesia.
Moonstone: The Feldspar with a Glow
Moonstone is a type of feldspar mineral and is known for its iridescent sheen, called adularescence, which gives it a soft, ethereal glow. This effect is caused by the interference of light with the internal structure of the mineral, which consists of alternating layers of orthoclase and albite.
Moonstone is typically found in granitic rocks and metamorphic deposits, and it is often mined in India, Sri Lanka, Myanmar, Madagascar, and the United States. The Indian moonstone, in particular, is highly prized for its blue sheen and clarity.
Alexandrite: The Rare Color-Changer
Alexandrite is a chrysoberyl gemstone known for its remarkable color-changing ability. In daylight, it appears green, while in incandescent light, it shifts to a reddish-purple hue. This color change is due to the presence of chromium, which absorbs certain wavelengths of light and reflects others.
Alexandrite is one of the rarest gemstones in the world, and natural alexandrite is extremely difficult to find. The first known deposit of alexandrite was discovered in the Ural Mountains of Russia in the 19th century. Today, alexandrite is primarily mined in Brazil, India, and Madagascar.
Due to its rarity, synthetic alexandrite is often used as an alternative. This lab-created version has the same chemical composition and optical properties as natural alexandrite and is more widely available.

Care and Cleaning
Proper care is essential for preserving the beauty and longevity of June birthstone jewelry. Each of the three stones has specific care requirements based on their hardness, luster, and sensitivity to light and heat.
Pearl
- Hardness: 2.5–4.5 on the Mohs scale
- Cleaning: Wipe with a soft, damp cloth after wearing. Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaning, as these can damage the nacre surface.
- Storage: Store pearls separately from other jewelry to prevent scratches. Keep them in a soft pouch or lined box.
- Avoid: Exposure to acids, perfumes, and lotions, as these can erode the nacre.
Moonstone
- Hardness: 6–6.5 on the Mohs scale
- Cleaning: Clean with warm, soapy water and a soft cloth or brush. Avoid ultrasonic and steam cleaning, as these can damage the delicate structure.
- Storage: Store moonstone away from direct sunlight to prevent fading and keep it dry to avoid internal clouding.
- Avoid: Exposure to extreme temperatures or chemicals, as these can affect the adularescence.
Alexandrite
- Hardness: 8.5 on the Mohs scale
- Cleaning: Clean with warm, soapy water and a soft cloth or brush. Avoid ultrasonic and steam cleaning, as these can damage the internal structure.
- Storage: Store alexandrite in a cool, dry place to prevent heat-induced changes in color.
- Avoid: Exposure to direct sunlight for extended periods, as this can cause fading or color shift.
