Additionally, we will examine how these stones are cared for and how they are used in jewelry today. Whether you are a gemstone enthusiast, a jewelry buyer, or a student of gemology, this exploration of June’s birthstones will offer valuable insight into their enduring appeal.
History and Lore
The Ancient Elegance of Pearl
Pearl, the oldest of June's birthstones, has been revered for centuries for its natural beauty and symbolic meaning. As early as ancient Rome, pearls were associated with Venus, the goddess of love and beauty, who was believed to have been born in the month of June. This connection has contributed to the long-standing association of pearls with purity, innocence, and love.
Pearls are formed within mollusks such as oysters and mussels, making them unique among gemstones for being the only ones that are not formed from minerals or crystals. Instead, they develop through a biological process that results in a smooth, lustrous surface and a soft, iridescent sheen. Their creation is seen as a symbol of life, transformation, and emotional depth, reflecting the inner beauty and serenity of the wearer.
The Traditional Glow of Moonstone
Moonstone, the traditional June birthstone since 1912, has captivated many with its ethereal glow. Its most striking feature is a phenomenon known as adularescence, a soft, shimmering light that appears to move across the stone's surface, reminiscent of moonlight. This effect is caused by the intergrowth of different mineral layers within the stone, typically feldspar, which scatter light in a way that creates a mystical, dreamlike appearance.
Historically, moonstone has been associated with lunar energy, emotional balance, and spiritual growth. It has been used in various cultures to enhance intuition and connect with the divine feminine. The stone's calming presence makes it particularly appealing to those who seek emotional stability and creative inspiration. In ancient times, moonstone was also believed to offer protection and was carried by travelers to ward off danger and bring good fortune.
The Modern Marvel of Alexandrite
Alexandrite is the youngest of June's birthstones, officially recognized as a birthstone in 1950. Its discovery in the 19th century in Russia sparked great interest due to its rare and extraordinary property of changing color under different lighting conditions. In daylight, alexandrite typically appears green, while under incandescent light, it shifts to a reddish or purplish hue. This color change is due to the presence of trace amounts of chromium in the crystal structure, which absorbs and reflects light in a unique way.
Alexandrite is often associated with duality, transformation, and personal growth, making it a particularly fitting gemstone for those born under the zodiac sign of Gemini. It is also believed to enhance intuition and stimulate creativity. Due to its rarity and captivating appearance, alexandrite has become highly sought after by collectors and jewelry enthusiasts alike.
Geological Formation and Sources
Pearl Formation and Sources
Pearls are formed within the soft tissue of mollusks such as oysters and mussels, when an irritant, such as a grain of sand, becomes trapped inside the shell. In response, the mollusk begins to secrete nacre, a calcium carbonate substance, around the irritant. Over time, layer upon layer of nacre is deposited, creating the smooth, lustrous surface of the pearl.
Natural pearls are rare and highly valuable, but the majority of pearls available today are cultured pearls, which are created through human intervention. Cultured pearls are produced by introducing a bead or piece of mantle tissue into the mollusk, which then triggers the same nacre-secreting process as natural pearls. This technique was first successfully developed in Japan in the early 20th century and has since led to a steady supply of high-quality pearls.
The most famous pearl-producing regions include Japan, China, the Persian Gulf, and the South Pacific. Each region produces pearls with slightly different characteristics, including color, size, and luster. For example, Japanese akoya pearls are known for their high luster and classic white color, while South Sea pearls are prized for their large size and rich colors, including white, gold, and silver.
Moonstone Formation and Sources
Moonstone is a type of feldspar, a group of silicate minerals that make up a large portion of the Earth's crust. It is formed through the slow cooling of magma, which allows for the development of distinct layers within the mineral. These layers interact with light in a way that creates the unique adularescence effect.
Moonstone is found in various parts of the world, including India, Sri Lanka, the United States (particularly in Georgia and North Carolina), and Madagascar. Indian moonstone is particularly well-known for its high-quality adularescence and is often used in jewelry. The U.S. has also produced some of the finest moonstone, especially in the Appalachian region, where it is mined alongside other gemstones.
The stone's color can vary from white and gray to pink, yellow, and even green. The most valuable moonstones exhibit a strong and clear shimmer, with a translucent to transparent body and minimal inclusions.
Alexandrite Formation and Sources
Alexandrite is a rare variety of chrysoberyl, a mineral composed of beryllium and aluminum. Its formation requires specific geological conditions, including the presence of both beryllium and chromium, which are typically found in different rock types. Alexandrite is formed when these elements come together in the same environment, often in metamorphic rocks or pegmatites.
The first known deposit of alexandrite was discovered in the Ural Mountains of Russia in the 19th century. However, the original Russian deposits have largely been exhausted, and most alexandrite now comes from Brazil, India, and Madagascar. Brazilian alexandrite is particularly notable for its vibrant color change, which can range from green in daylight to a deep red under incandescent light.
Due to its rarity and the difficulty of finding high-quality stones, alexandrite is considered one of the most valuable gemstones in the world. Stones with a strong and distinct color change, as well as good clarity and size, command the highest prices in the market.

Care and Cleaning
Proper care is essential to maintaining the beauty and longevity of June birthstones. Each gemstone requires specific handling and cleaning methods due to its unique properties.
Pearl Care
Pearls are relatively soft and porous, making them sensitive to harsh chemicals, excessive heat, and prolonged exposure to sunlight. To clean pearls, gently wipe them with a soft, damp cloth after wearing. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the nacre. Store pearls separately from other gemstones to prevent scratches, and keep them in a soft pouch or cloth.
Moonstone Care
Moonstone is more durable than pearl but still requires gentle handling. It should be cleaned with a soft cloth and mild soap and water. Avoid using harsh chemicals or abrasive materials, as these can dull the stone's surface. Store moonstone in a soft pouch or cloth to prevent scratches and keep it away from direct sunlight to maintain its luster.
Alexandrite Care
Alexandrite is a relatively hard gemstone but can still be damaged by harsh chemicals or extreme temperatures. To clean it, use a soft cloth and warm water. Avoid using ultrasonic or steam cleaners, as these can cause thermal shock or damage the stone's clarity. Store alexandrite in a soft pouch or cloth to prevent scratches and keep it away from direct sunlight to preserve its color-changing properties.
