June is a month rich in symbolism and gemological significance, distinguished by the unique tradition of assigning not one, but three official birthstones: pearl, moonstone, and alexandrite. This trinity of gemstones reflects the evolving nature of birthstone lore and the diverse personalities of those born under the zodiac signs of Gemini (May 21–June 20) and Cancer (June 21–July 22). Each of these stones carries its own set of physical, historical, and metaphysical attributes, making June one of the most fascinating months in the birthstone calendar. This article delves into the geological properties, cultural meanings, and practical considerations for each of these gemstones, offering a detailed exploration for gemstone enthusiasts, jewelry connoisseurs, and students of gemology.
History and Lore
The tradition of birthstones traces its roots to ancient civilizations, particularly the biblical Book of Exodus, where the twelve stones on Aaron’s breastplate were believed to represent the twelve tribes of Israel. Over time, these stones were associated with the months of the year and eventually became symbolic of personal identity and protection.
June’s birthstone tradition began with the pearl, which was revered in ancient cultures for its natural formation and association with purity and wisdom. Pearls were often seen as gifts from the sea, embodying the feminine principle and the cyclical nature of life. As birthstone charts evolved, moonstone and alexandrite were added to the list in the 20th century, particularly to accommodate shifting consumer preferences and the rarity of natural pearls.
The pearl remains the most historically significant of the three, with a legacy that spans centuries. Ancient Chinese, Roman, and Persian cultures all valued pearls for their beauty and symbolic depth. The moonstone, with its ethereal glow, was adopted later, especially in European traditions, and is often linked to intuition and emotional balance. Alexandrite, the rarest of the three, was discovered in the 19th century and gained popularity in the 1950s due to its unique color-changing properties, making it a modern addition to the June birthstone roster.
The inclusion of these three gemstones reflects a blend of historical reverence, cultural evolution, and gemological diversity. It allows individuals born in June to choose a stone that aligns with their personal style and spiritual inclinations, whether they are drawn to the timeless elegance of the pearl, the mystical aura of the moonstone, or the transformative energy of alexandrite.
Geological Formation and Sources
Each of June’s birthstones has a distinct origin and formation process, influenced by geological conditions over thousands of years.
Pearl
The pearl is the only organic gemstone among the three, formed through a biological process inside mollusks such as oysters and mussels. When an irritant, like a grain of sand, enters the shell, the mollusk coats it with layers of nacre, a substance composed primarily of calcium carbonate and conchiolin. Over time, this process results in the creation of a smooth, lustrous pearl. The color and quality of a pearl depend on the species of mollusk, the water conditions, and the length of time it takes to form.
Natural pearls are relatively rare, which is why cultured pearls—those grown with human intervention—are more commonly available today. The primary sources for natural and cultured pearls include India, Japan, China, and Tahiti. Each region produces pearls with distinct characteristics: Japanese akoya pearls are known for their round shape and high luster, while Tahitian pearls are larger and display a range of colors from black to green.
Moonstone
Moonstone is a type of feldspar, a mineral group that includes over 20 different species. Specifically, the moonstone used in jewelry is typically adularia, a potassium aluminum silicate with a chemical formula of KAlSi₃O₈. It is formed in igneous and metamorphic rocks and is characterized by its adularescence, a shimmering effect caused by the refraction of light through layers of different mineral structures.
Moonstone is found in various locations around the world, including Sri Lanka, India, Brazil, and Madagascar. The most prized moonstones are those with a strong, silvery sheen and minimal cloudiness. The color variations in moonstone—white, yellow, orange, peach, pink, and light blue—are due to trace elements present during formation.
Alexandrite
Alexandrite is a rare and highly sought-after gemstone, known for its color-changing ability. It is a variety of chrysoberyl, with the chemical formula BeAl₂O₄. The color change is due to the presence of chromium and iron, which alter the way light is absorbed and reflected. In daylight, alexandrite appears green or bluish-green, while under incandescent light, it takes on a reddish-purple hue.
Alexandrite was first discovered in the Ural Mountains of Russia in the 19th century, and it was named after the Russian Tsar Alexander II. Today, the most significant sources of alexandrite include Brazil, India, and Madagascar. High-quality alexandrite is extremely rare, especially in larger sizes, which contributes to its high market value.

Each of June’s birthstones has been associated with specific meanings and metaphysical properties across different cultures and eras. These beliefs often reflect the unique characteristics of the gemstone and the values of the societies that revered them.
Pearl – Purity, Sincerity, and Spiritual Wisdom
Pearls have long been symbols of purity, innocence, and feminine energy. In many ancient cultures, they were believed to be the embodiment of the moon and its cyclical nature, representing the journey of life and the importance of inner transformation. In Chinese tradition, pearls were associated with longevity and immortality, while in Roman culture, they were considered symbols of love and fertility.
Metaphysically, pearls are believed to promote emotional balance, truthfulness, and clarity of thought. They are often used in meditation and healing practices to enhance self-awareness and spiritual growth. Pearls are also said to encourage generosity, compassion, and harmony in relationships.
Moonstone – Intuition, Hope, and Emotional Balance
Moonstone has long been associated with intuition, feminine power, and emotional balance. In ancient Rome and India, it was believed to be formed from moonbeams, and it was used to enhance clarity of mind and emotional stability. It was also considered a lucky stone, especially for travelers and those seeking new beginnings.
In modern metaphysical practices, moonstone is believed to support emotional healing, mental clarity, and inner peace. It is often used to calm anxiety, reduce stress, and promote a sense of hope and optimism.

Due to its rarity and unique properties, alexandrite is often considered a stone of destiny, helping individuals navigate life’s transitions with grace and confidence.
Care and Cleaning
Proper care is essential for preserving the beauty and longevity of June’s birthstones. Each gemstone requires specific handling and cleaning methods based on its physical properties.
Pearl
Pearls are relatively soft (2.5–4.5 on the Mohs scale) and susceptible to damage from harsh chemicals, heat, and moisture. To clean a pearl, gently wipe it with a soft, damp cloth after wearing. Avoid using ultrasonic or steam cleaners, as these can cause surface damage or loosening of the nacre. Store pearls separately from other gemstones to prevent scratches, and avoid exposure to perfumes, lotions, and cosmetics, as they can dull the luster.
Moonstone
Moonstone is moderately durable (6–6.5 on the Mohs scale) but not resistant to harsh abrasives or high heat. To clean moonstone, use warm, soapy water and a soft cloth or brush. Ultrasonic cleaners are generally safe for moonstone, but steam cleaners should be used with caution, as they may cause structural damage. Store moonstone away from harder gemstones to prevent scratching, and avoid prolonged exposure to direct sunlight, which can cause fading of color.
Alexandrite
Alexandrite is one of the hardest June birthstones (8.5 on the Mohs scale) and is very durable, making it suitable for everyday wear. It is also resistant to scratches and chipping, even in a ring setting. To clean alexandrite, use warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally safe for alexandrite, but it is best to avoid abrasive materials and harsh chemicals. Due to its color-changing properties, alexandrite should be stored in a dark place to preserve its optical effects.
