June is among the few months in the calendar year that boast not one, but three birthstones: pearl, moonstone, and alexandrite. This unique distinction offers individuals born in June a wealth of choices when it comes to celebrating their birth month with a meaningful gemstone. Each of these three birthstones has its own distinct characteristics, historical significance, and cultural symbolism. This article delves into the fascinating world of June’s birthstones, exploring their geological properties, historical origins, and enduring appeal in jewelry and personal adornment.
History and Lore
The tradition of assigning gemstones to specific months has its roots in ancient times. According to historical sources, the practice of associating gemstones with months can be traced back to the 12 tribes of Israel. The ancient Israelites believed that each of the 12 tribes should be represented by a unique gemstone, which were set in the breastplate of the high priest Aaron. This practice laid the foundation for the modern concept of birthstones, where each month of the year is associated with a particular gemstone.
The June birthstones—pearl, moonstone, and alexandrite—each have their own rich histories. Pearls, for instance, have been cherished for millennia. Ancient cultures often viewed pearls as divine gifts. The Middle East believed pearls were teardrops from heaven, while the Chinese attributed their formation to the brain of a dragon. These mystical beliefs contributed to the pearl's enduring allure.
Moonstone, with its ethereal glow, has also captivated people throughout history. Ancient Romans believed that moonstone was formed from moonbeams and gave it to their goddess Diana. In India, moonstone has been revered for centuries, particularly in the context of the moon’s influence on human emotions and well-being.
Alexandrite, the youngest of the three June birthstones, has a more modern origin. It was discovered in the Ural Mountains of Russia on the birthday of Czar Alexander II, after whom the stone was named. Its remarkable color-changing property, transitioning from green in daylight to red under incandescent light, made it an instant marvel among gemologists and collectors.
Geological Formation and Sources
Each of June’s birthstones has a unique geological origin and formation process.
Pearl
Pearls are organic gemstones formed within the soft tissue of living organisms—primarily mollusks such as oysters and mussels. When an irritant, such as a grain of sand, enters the mollusk’s shell, it secretes a substance called nacre to coat the irritant. Over time, layers of nacre build up, forming a pearl. Natural pearls are rare, and most pearls available today are cultured, meaning they are formed under controlled conditions in pearl farms.
Cultured pearls are produced in various parts of the world, including Japan, China, Indonesia, and the South Sea islands. These pearls come in a range of colors, from classic white and cream to rare black and pink hues.
Moonstone
Moonstone is a type of feldspar mineral known for its adularescence, a phenomenon that gives the stone its characteristic shimmer. This effect is caused by the intergrowth of two feldspar minerals—orthoclase and albite. Light is refracted between the layers of these minerals, creating a glowing, ethereal effect that resembles moonlight.
Moonstone is typically found in igneous and metamorphic rocks and is mined in various locations around the world, including India, Sri Lanka, Brazil, and the United States. The most prized moonstone is milky white with a blue sheen, although other colors such as peach and yellow are also available.
Alexandrite
Alexandrite is a rare and valuable variety of the mineral chrysoberyl. Its color-changing property is due to the presence of trace amounts of chromium, which causes the stone to appear green in daylight and red under incandescent light. This unique characteristic is known as pleochroism.
Alexandrite is primarily found in metamorphic rocks and is mined in countries such as Russia, Brazil, and India. The first alexandrite deposits were discovered in the Ural Mountains of Russia in the 19th century. However, as these deposits were depleted, new sources in Brazil and other regions emerged, ensuring the continued availability of this rare gemstone.
Gemological Properties
Understanding the gemological properties of each of June’s birthstones is essential for appreciating their beauty and value.
Pearl
- Hardness: 2.5–4.5 on the Mohs scale
- Chemical Composition: Calcium carbonate (CaCO₃) with a protein-based organic matrix
- Color: White, cream, pink, black, and other hues depending on the type of mollusk and environment
- Luster: Waxy to pearly
- Transparency: Opaque to translucent
- Cleavage: None
Pearls are relatively soft and require careful handling. They are sensitive to acidic and alkaline substances and can be damaged by harsh chemicals or prolonged exposure to sunlight.
Moonstone
- Hardness: 6–6.5 on the Mohs scale
- Chemical Composition: A mixture of orthoclase and albite feldspar minerals
- Color: Milky white, peach, yellow, and blue sheen
- Luster: Pearly to vitreous
- Transparency: Translucent to transparent
- Cleavage: Perfect cleavage in two directions
Moonstone is known for its unique adularescence, which gives it a glowing, moonlit appearance. Its cleavage makes it prone to chipping, so it is often cut as a cabochon to avoid sharp edges.
Alexandrite
- Hardness: 8.5–9 on the Mohs scale
- Chemical Composition: Beryllium aluminum oxide (BeAl₂O₄)
- Color: Green in daylight, red under incandescent light
- Luster: Vitreous
- Transparency: Transparent to translucent
- Cleavage: None
Alexandrite is a durable gemstone with a high refractive index, making it ideal for faceting. Its rarity and color-changing property make it one of the most sought-after gemstones in the world.

Care and Cleaning
Proper care and cleaning are essential for preserving the beauty and longevity of June’s birthstones.
Pearl
Pearls require gentle handling due to their soft surface. Avoid exposing them to harsh chemicals, such as perfumes, lotions, and cleaning agents. Clean pearls with a soft, damp cloth, and store them in a soft pouch to prevent scratches. Avoid exposing pearls to prolonged sunlight, as this can cause them to lose their luster.
Moonstone
Moonstone should be cleaned with a soft cloth and warm, soapy water. Avoid using ultrasonic cleaners or steamers, as these can damage the stone. Store moonstone in a soft cloth or jewelry box to prevent scratches. Due to its cleavage, moonstone should be handled with care to avoid chipping.
Alexandrite
Alexandrite is more durable than pearls and moonstone but still requires proper care. Clean it with a soft cloth and warm, soapy water. Avoid exposing it to extreme temperatures or harsh chemicals. Store alexandrite in a dry, cool place to prevent any potential damage.
