By examining these aspects in detail, we gain a deeper appreciation for the allure and significance of these June birthstones.
History and Lore
Moonstone: A Gem of Intuition and Transformation
Moonstone has a rich history that spans various cultures and time periods. In ancient Rome, moonstone was believed to be formed from moonbeams and was associated with the goddess Diana, the deity of the moon. This connection to lunar energy persisted in various forms through the centuries, with moonstone often being considered a stone of intuition, hope, and emotional balance.
In Indian culture, moonstone has been used in jewelry and spiritual practices for thousands of years. It is particularly associated with the Hindu god of the moon, Chandra, and is believed to bring peace and stability to those who wear it. The stone is also thought to promote emotional healing and is often used during times of change or transition.
In the modern era, moonstone was officially recognized as a June birthstone in 1912 by the National Association of Jewelers of America. It has since become a popular gemstone for those seeking emotional equilibrium and spiritual insight. Its soft, glowing appearance and gentle energy make it a favorite among those who value intuition and emotional clarity.
Alexandrite: A Rare and Magical Discovery
Alexandrite is a relatively new addition to the June birthstone list. Discovered in 1830 in the Ural Mountains of Russia, alexandrite is named after Tsar Alexander II of Russia, who was born on the same day the gemstone was discovered—April 29. The stone quickly gained royal favor and was often used in jewelry for the Russian imperial family.
Alexandrite is known for its unique color-changing property, shifting from green in daylight to red or purplish-red under incandescent light. This phenomenon is caused by the way the gemstone absorbs and reflects light, and it is one of the reasons why alexandrite is considered so rare and valuable. The color change is particularly striking and has earned the gemstone a reputation for being a "chameleon" of the gem world.
Alexandrite was officially added to the June birthstone list in 1952, recognizing its significance as a rare and magical gem. It is often associated with transformation, balance, and good fortune. In some cultures, alexandrite is believed to bring protection and prosperity, making it a powerful and meaningful gemstone.
Geological Formation and Sources
Moonstone: A Product of Nature's Layering
Moonstone is a type of feldspar that exhibits a phenomenon known as adularescence, which is the soft, glowing light that seems to float just beneath the surface of the stone. This effect is caused by the intergrowth of two different feldspar minerals—orthoclase and albite—within the gemstone. The alternating layers of these minerals create a reflective surface that gives moonstone its characteristic shimmer.
Moonstone is found in various parts of the world, including India, Sri Lanka, Brazil, and the United States. India is one of the most well-known sources of moonstone, particularly for the high-quality stones used in jewelry. The gemstone is often mined in alluvial deposits, where it has been weathered and transported by water before being deposited in new locations.
The formation of moonstone is a slow process that occurs over millions of years. It begins deep within the Earth's crust, where magma cools and solidifies. As the magma cools, the feldspar minerals within it begin to crystallize. The layering process that gives moonstone its unique appearance occurs as the minerals grow and intermingle, creating the conditions necessary for adularescence.
Alexandrite: A Rare and Valuable Gem
Alexandrite is a rare variety of chrysoberyl, a mineral composed of beryllium and aluminum. The color-changing property of alexandrite is due to the presence of trace amounts of chromium, which is responsible for the green color in daylight and the red color under incandescent light. This unique characteristic makes alexandrite one of the most sought-after gemstones in the world.
The original source of alexandrite was the Ural Mountains in Russia, where it was first discovered in 1830. However, due to the depletion of this deposit, alexandrite is now more commonly found in Brazil, Madagascar, and Sri Lanka. Brazil is currently the leading source of alexandrite, producing some of the finest examples of the gemstone. The deposits in Brazil are located in the state of Minas Gerais, where the gemstone is found in granitic pegmatites.
The formation of alexandrite occurs under specific geological conditions. It is typically found in metamorphic rocks, where the presence of chromium and the correct chemical environment allow for the formation of the gemstone. The process is complex and requires a precise combination of temperature, pressure, and chemical composition. Because of these stringent requirements, alexandrite is considered one of the rarest gemstones in the world.
Gemological Properties
Moonstone: Softness and Ethereal Beauty
Moonstone is a relatively soft gemstone, with a hardness of 6 to 6.5 on the Mohs scale. This means that it is not as durable as harder gemstones like diamonds or sapphires, and it requires careful handling to prevent scratches and damage. Despite its softness, moonstone is prized for its unique optical properties and gentle energy.
The chemical composition of moonstone is primarily orthoclase feldspar, which is a potassium aluminum silicate. The presence of albite feldspar, another type of feldspar, contributes to the intergrowth that creates the adularescence effect. Moonstone is typically found in a range of colors, including white, gray, and colorless, with the most desirable specimens exhibiting a blue sheen.
In terms of clarity, moonstone is often opaque or translucent, with the adularescence effect being more visible in stones that are slightly opaque. The cut of moonstone is usually cabochon, which enhances the stone's shimmer and allows the light to reflect off the surface in a way that maximizes the ethereal effect.
Moonstone is also known for its vitreous luster, which gives it a glassy appearance. The size of moonstone gemstones can vary, but they are typically cut into smaller sizes to preserve the integrity of the stone and enhance the visual appeal of the adularescence.
Alexandrite: Hardness and Color Change
Alexandrite is a much harder gemstone than moonstone, with a hardness of 8.5 on the Mohs scale. This makes it more suitable for everyday wear in jewelry, as it is less likely to scratch or chip under normal conditions. The high hardness of alexandrite is one of the reasons why it is considered a durable and long-lasting gemstone.
The chemical composition of alexandrite is beryllium aluminum oxide (BeAl₂O₄), with the presence of chromium responsible for the gemstone's color-changing property. The chromium content in alexandrite is typically between 0.01% and 0.05%, which is sufficient to create the green and red color shift. This color change is most noticeable when the stone is viewed under different light sources, such as daylight and incandescent light.
In terms of clarity, alexandrite is generally transparent to slightly translucent, with the best examples being clear and free of inclusions. The cut of alexandrite is usually brilliant or mixed cut, which allows for maximum light reflection and enhances the color change effect. Alexandrite is also known for its vitreous luster, which gives it a glassy and polished appearance.
Alexandrite is one of the few gemstones that exhibit a color change, making it a rare and valuable gem. The size of alexandrite gemstones can vary, but the larger and more vivid the color change, the more valuable the stone. High-quality alexandrite is often cut into smaller sizes to preserve the integrity of the gemstone and maximize the color change effect.

Care and Cleaning
Moonstone: Gentle Handling for Delicate Beauty
Because moonstone is a relatively soft gemstone, it requires careful handling to prevent damage. It should be stored separately from harder gemstones to avoid scratches. When cleaning moonstone, it is best to use a soft cloth and mild soap with warm water. Avoid using ultrasonic cleaners or steamers, as these can damage the stone's surface.
Moonstone should also be protected from exposure to harsh chemicals, as these can dull its luster and affect the adularescence. It is best to remove moonstone jewelry before engaging in activities that may expose it to abrasive substances or rough handling.
