June is a unique month in the realm of birthstones, as it is associated with not one, but three distinct gemstones: Pearl, Moonstone, and Alexandrite. Each of these stones carries its own distinct color, historical significance, and cultural symbolism, making June one of the most versatile and intriguing months in the birthstone calendar. One of the most frequently asked questions about June birthstones is whether the color purple is part of the birthstone palette for this month. The answer lies in the presence of Alexandrite, a rare and fascinating gemstone that exhibits a color change from green in daylight to reddish-purple under incandescent light. This article explores the June birthstones in depth, focusing on their colors, geological properties, historical and cultural significance, and their roles in modern jewelry and metaphysical beliefs.
Introduction
June is the only month in the birthstone calendar to have three officially recognized gemstones: Pearl, Moonstone, and Alexandrite. These stones are celebrated for their diversity in color, texture, and symbolism. While Pearl and Moonstone are more traditionally associated with softer, neutral tones—Pearl in white or cream and Moonstone in milky white with a bluish shimmer—Alexandrite introduces a more vibrant and dynamic element to the June birthstone collection with its light purple to reddish-purple hue under certain lighting conditions. This color-changing quality makes Alexandrite particularly unique and adds a layer of intrigue to the June birthstone palette.
This article delves into the three June birthstones, examining their physical properties, historical uses, cultural symbolism, and care requirements. By exploring each gemstone in detail, we gain a deeper understanding of why these stones continue to captivate gemologists, jewelers, and collectors alike.
History and Lore
Pearl: A Symbol of Purity and Power
Pearls have a long and storied history, dating back to ancient civilizations. As early as 2300 BC in China, pearls were treasured by the royal family and were considered symbols of power and status. In ancient Rome, pearls were also revered, often worn by the elite to display their wealth and influence. The cultural significance of pearls continued through the centuries, and by the early 20th century, Japan’s invention of pearl cultivation technology made pearls more accessible to a wider audience. Despite this, natural pearls remain extremely rare and highly valued by collectors.
Pearls are not only admired for their beauty but also for their symbolic meaning. They have long been associated with purity, wisdom, and loyalty. In many cultures, pearls were believed to bring protection and peace to the wearer. Today, pearls are a timeless choice for jewelry, representing elegance and inner strength.
Moonstone: A Gift from the Moon Goddess
Moonstone, the feldspar mineral birthstone for June, has long been regarded as a sacred gem in various cultures. In Hinduism and Roman mythology, moonstone was believed to be a gift from the moon goddess, and it was associated with intuition, emotional healing, and new beginnings. In ancient India, moonstone was considered a symbol of good luck and inspiration. In medieval Europe, it was thought to restore love and harmony, making it a popular gemstone for those seeking emotional balance.
The unique optical phenomenon known as the "moonlight effect" or "schiller" gives moonstone its ethereal glow. This effect is caused by the interplay of light within the stone’s structure, creating a soft, shimmering light that resembles the glow of the moon. During the Art Nouveau period, moonstone became especially popular in jewelry, celebrated for its dreamy, mystical appearance.
Alexandrite: The Color-Changing Wonder
Alexandrite is a relatively new discovery in the world of gemology, having been discovered in the Ural Mountains of Russia in 1830. It was named after Tsar Alexander II, and in the 19th century, it quickly became a symbol of imperial power and glory, favored by the Russian nobility. What sets alexandrite apart is its remarkable color-changing property—it appears green in daylight and shifts to a reddish-purple under incandescent light. This unique characteristic makes it one of the most sought-after and valuable gemstones in the world.
High-quality natural alexandrite is extremely rare, which contributes to its high market and collector value. Because of its scarcity, most alexandrite in jewelry today is lab-created, yet it retains the same chemical composition and color-changing properties as its natural counterpart. Alexandrite symbolizes transformation, adaptability, and good fortune, making it a meaningful and powerful gemstone.
Geological Formation and Sources
Pearl: The Organic Gem
Pearls are the only organic birthstones, formed within mollusks such as oysters and mussels. When a foreign particle enters the mollusk, it secretes layers of nacre around the irritant to protect itself, eventually forming a pearl. This process can take several years, and the size, shape, and color of the pearl depend on the type of mollusk and the environment in which it was formed. Pearls can be found in both freshwater and seawater environments, and their colors range from white and cream to pink, gold, blue, and even black.
Moonstone: The Feldspar with a Shimmer
Moonstone is a type of feldspar, specifically the orthoclase feldspar that exhibits adularescence, the optical phenomenon responsible for its shimmering effect. This effect occurs due to the intergrowth of different mineral layers within the stone, which scatter light and create a soft, bluish sheen. Moonstone can be found in a variety of colors, from transparent to white, green, yellow-brown, grey, and even black. However, the most prized and popular moonstone is the milky white variety with a blue shimmer.
Moonstone is mined in several locations around the world, including India, Sri Lanka, Brazil, and the United States. The quality of moonstone is determined by the strength and clarity of its schiller effect, with the most valuable stones displaying a strong, consistent shimmer.
Alexandrite: The Rare Color-Changer
Alexandrite is a rare chrysoberyl mineral that is known for its color-changing properties. It is primarily composed of beryllium and aluminum, and its color change is due to trace amounts of chromium and vanadium. The green color is caused by chromium absorbing light in the red and blue parts of the spectrum, while the reddish-purple color under incandescent light is due to the absorption of green light.
Natural alexandrite is extremely rare, and high-quality specimens are mostly found in Brazil, Madagascar, and India. Due to the scarcity of natural alexandrite, most jewelry-grade alexandrite is produced in laboratories. These synthetic stones are chemically identical to their natural counterparts and exhibit the same color-changing properties.

Care and Cleaning
Pearl
Pearls are relatively soft and require gentle care to maintain their luster and integrity. They should be cleaned with a soft, damp cloth and mild soap solution. Avoid using harsh chemicals, ultrasonic cleaners, or steam cleaners, as these can damage the surface of the pearl. Pearls should also be stored separately from other gemstones to prevent scratches.
Moonstone
Moonstone is slightly harder than pearls but still requires careful handling. It should be cleaned with a soft cloth and warm, soapy water. Avoid using ultrasonic or steam cleaners, as these can cause the stone to crack or lose its luster. Moonstone should be stored in a soft pouch or box to prevent scratches from harder gemstones.
Alexandrite
Alexandrite is one of the hardest gemstones and is more durable than pearls and moonstone. However, it should still be cleaned with a soft cloth and warm, soapy water. Avoid using harsh chemicals or abrasive cleaners, as these can dull the stone's luster. Alexandrite can be cleaned in an ultrasonic cleaner if it is free of inclusions and fractures.
