June is a unique month in the world of birthstones, as it is one of only a few months that are associated with three distinct gemstones: pearl, moonstone, and alexandrite. Each of these stones has a rich history, distinctive gemological properties, and unique cultural significance that has contributed to their enduring popularity. Together, they form a diverse and meaningful selection for those born in June, offering a range of choices that reflect both personal taste and historical tradition. This article delves into the characteristics, origins, and symbolism of each of these gemstones, providing a comprehensive overview of the June birthstones and their significance in both historical and contemporary contexts.
History and Lore
The tradition of assigning gemstones to each month of the year has ancient roots. Some historians trace the origins of this practice to the 12 tribes of Israel and the breastplate of Aaron, a sacred garment worn by the high priest that was adorned with 12 distinct gemstones, each representing one of the tribes. This early association of gemstones with identity and divine significance gradually evolved into the modern concept of birthstones, where each month is represented by one or more stones. By the 19th and 20th centuries, this tradition had become widely accepted in Western cultures, with June's birthstones being among the most notable for their diversity and beauty.
Pearls have been cherished for thousands of years. Ancient civilizations, including the Egyptians, Greeks, and Romans, valued pearls for their rarity and beauty. The Roman naturalist Pliny the Elder wrote extensively about pearls, calling them "the gems of the sea" and attributing them with the power to bring health and longevity. In China, pearls were considered symbols of wisdom and purity and were often used in imperial regalia.
Moonstone, another of June’s birthstones, has also been revered across cultures for its ethereal glow. The Romans believed moonstone to be solidified moonbeams and associated it with lunar deities. In India, moonstone was known as the "dream stone" and was believed to bring good dreams and promote fertility. The stone’s mystical qualities contributed to its use in the Art Nouveau movement of the early 20th century, where its iridescence was celebrated in intricate jewelry designs.
Alexandrite, the most modern of June’s birthstones, was discovered in the Ural Mountains of Russia in the early 19th century. According to legend, the stone was found on the birthday of Czar Alexander II, after whom it was named. Alexandrite quickly became a prized gem due to its rare and striking color-changing property. Unlike the other June birthstones, which have ancient histories, alexandrite was a relatively recent addition to the birthstone tradition, officially recognized in the 20th century. Its discovery marked a turning point in the appreciation of color-changing gemstones and added a new dimension to the June birthstone collection.
Geological Formation and Sources
Each of June’s birthstones forms under unique geological conditions and is found in different parts of the world.
Pearl
Unlike most gemstones, pearls are organic gemstones formed within the soft tissue of a living organism—specifically, mollusks such as oysters and mussels. The formation of a pearl begins when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk secretes nacre, a calcium carbonate substance that gradually coats the irritant, layer by layer, over the course of months or even years. The result is a smooth, lustrous pearl. Pearls can be found in both saltwater and freshwater environments, with the most valuable pearls typically coming from saltwater oysters, particularly those in the Gulf of Mexico, Japan, China, and Southeast Asia.
Moonstone
Moonstone is a type of feldspar, a group of silicate minerals that make up a significant portion of the Earth's crust. The unique iridescent sheen of moonstone, known as adularescence, is caused by the intergrowth of two different feldspar minerals—orthoclase and albite—which are layered in microscopic sheets. When light reflects off these layers, it creates the characteristic bluish-white shimmer that gives moonstone its name. Moonstone is most commonly found in Sri Lanka, where the finest specimens are pale blue and nearly translucent. Other significant sources include India, Nepal, Brazil, and the United States.
Alexandrite
Alexandrite is a rare variety of the mineral chrysoberyl, and its formation is a result of a very specific combination of geological factors. The presence of chromium or vanadium in the crystal structure of chrysoberyl is responsible for its color-changing property. Alexandrite is typically formed in granite-rich environments where the right chemical conditions exist for the mineral to develop. The original deposits in the Ural Mountains of Russia were depleted by the early 20th century, but new deposits were later discovered in Brazil, Madagascar, and India. These deposits allowed for the continued availability of alexandrite, though it remains a rare and highly valued gemstone.
Gemological Properties
Understanding the gemological properties of each of June’s birthstones provides insight into their appearance, durability, and care requirements.
Pearl
- Type: Organic gemstone
- Composition: Calcium carbonate (aragonite), water, and conchiolin
- Hardness: 2.5–4.5 on the Mohs scale
- Color: White, pink, cream, black, and other hues depending on the mollusk species and environmental factors
- Luster: Pearly luster
- Transparency: Opaque to semi-transparent
- Cleavage: None (due to organic composition)
- Density: 2.6–2.8 g/cm³
Pearls are relatively soft compared to other gemstones, which means they are more susceptible to damage from abrasion, heat, and acidic substances. Their luster and color can also fade over time if not properly cared for.
Moonstone
- Type: Feldspar mineral (specifically, orthoclase-albite intergrowth)
- Composition: KAlSi₃O₈ (orthoclase) and NaAlSi₃O₈ (albite)
- Hardness: 6–6.5 on the Mohs scale
- Color: White, pink, gray, green, and brown
- Luster: Vitreous to pearly
- Transparency: Translucent to transparent
- Cleavage: Perfect cleavage in two directions at 90°
- Density: 2.5–2.6 g/cm³
Moonstone is relatively soft and has perfect cleavage, which makes it prone to chipping if struck. Its adularescence is a key feature that distinguishes it from other feldspar varieties.
Alexandrite
- Type: Variety of chrysoberyl
- Composition: BeAl₂O₄
- Hardness: 8.5 on the Mohs scale
- Color: Green in daylight or fluorescent light, red or purplish in incandescent light
- Luster: Vitreous
- Transparency: Transparent to translucent
- Cleavage: Poor cleavage
- Density: 3.7–3.9 g/cm³
Alexandrite is very durable due to its high hardness and lack of cleavage, making it suitable for everyday wear. Its color change is one of the most striking features in the gemstone world and is highly valued by collectors and jewelry enthusiasts.
Symbolism and Metaphysical Beliefs
June’s birthstones are not only admired for their beauty but also for the symbolism and metaphysical properties attributed to them.
Pearl
Pearls have long been associated with purity, wisdom, and longevity. In many cultures, pearls are seen as symbols of inner beauty and emotional balance. Ancient Chinese emperors believed pearls to be the pearls of the moon, representing immortality and divine power. In Western traditions, pearls are often associated with modesty and innocence, making them a popular choice for baptismal gifts and bridal jewelry. Some metaphysical beliefs suggest that pearls can enhance emotional stability and inner peace, promoting self-love and compassion.
Moonstone
Moonstone is often linked to feminine energy, intuition, and emotional balance. It is considered a stone of new beginnings, particularly in matters of love and emotional growth. In ancient Rome, moonstone was believed to be made of solidified moonlight, and it was associated with the goddess Luna. In India, moonstone is believed to promote fertility and good dreams, and it is often used in Ayurvedic medicine for its calming properties. Modern crystal healers suggest that moonstone can help with emotional healing, balance of the feminine and masculine energies, and enhanced intuition.

Because of its color change, it is often associated with transformation, balance, and harmony. In metaphysical traditions, alexandrite is believed to enhance mental clarity, emotional resilience, and spiritual awareness. Some also believe that it can help with healing from heartbreak or emotional pain and is a stone of hope and renewal. Due to its rarity and beauty, alexandrite is often seen as a stone of luxury and personal power.
Care and Cleaning
Proper care is essential to maintaining the beauty and longevity of June’s birthstones.
Pearl
Pearls are very sensitive to heat, chemicals, and abrasion. They should be stored separately from other gemstones to avoid scratches and should not be exposed to perfumes, lotions, or harsh cleaning agents. To clean pearls, use a soft, damp cloth and gently wipe them to remove any dirt or oils. Avoid using ultrasonic cleaners, as they can damage the nacre and cause the pearls to become dull or discolored. It is also important to dry pearls thoroughly after cleaning to prevent water from seeping into the nacre and causing microscopic cracks.
Moonstone
Moonstone should be protected from hard knocks, as its perfect cleavage makes it prone to chipping. It is also sensitive to heat and should not be exposed to high temperatures. Moonstone can be cleaned with warm, soapy water, using a soft cloth or a soft-bristled brush. Ultrasonic cleaners are generally safe for moonstone, but it is best to consult a professional jeweler if you are unsure. Moonstone should be stored in a soft pouch to prevent scratches and should not be exposed to direct sunlight for extended periods, as this can cause fading.
Alexandrite
Alexandrite is very durable and can be cleaned with warm, soapy water and a soft cloth. Ultrasonic cleaners are safe for alexandrite, as long as the stone does not have any filling or inclusions that could be affected. Because of its high hardness, alexandrite can be worn daily and is resistant to scratches and abrasions. However, it is still a good idea to remove alexandrite jewelry before engaging in activities that involve physical contact to prevent impact damage. Alexandrite should be stored in a dry, secure place to prevent tarnishing of the metal setting.
