Geological Formation and Sources
Each of June’s birthstones—pearl, moonstone, and alexandrite—has a distinct geological origin and formation process, which contributes to their unique properties and allure.
Pearl
Pearls are organic gems formed within the soft tissue of mollusks such as oysters and mussels. Unlike minerals, which are formed through geological processes, pearls are created through biological means. The formation begins when an irritant, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk secretes a substance called nacre, also known as mother-of-pearl, around the irritant. Over time, layer upon layer of nacre builds up, forming a pearl. The process can take several years, and the result is a gemstone that is both smooth and lustrous.
Natural pearls are relatively rare, as they form without human intervention. Most pearls available in the market today are cultured pearls, which are produced through a controlled process. In this method, a bead nucleus is implanted into the mollusk, which then coats it with nacre. Cultured pearls can be found in both saltwater and freshwater environments. Saltwater pearls, such as those from the Persian Gulf, the Indian Ocean, and the South China Sea, are typically round and have a high luster. Freshwater pearls, on the other hand, are more commonly irregular in shape and are produced in lakes and rivers, particularly in China.
Moonstone
Moonstone is a type of feldspar mineral, known for its adularescence—a visual effect that creates a glowing, silvery sheen on the surface of the stone. This effect is caused by the reflection of light from the alternating layers of different feldspar minerals within the crystal structure. Moonstone is typically white or gray in color, with flashes of blue, but it can also appear in other colors, such as orange, yellow, and green.
Moonstone is found in various parts of the world, including India, Sri Lanka, Brazil, and the United States. The most prized moonstone comes from India and Sri Lanka, where it is often used in traditional jewelry and spiritual practices. The stone’s ethereal glow and connection to the moon have made it a popular choice for those seeking emotional balance and intuition.
Alexandrite
Alexandrite is a rare and highly valued gemstone that is a variety of the mineral chrysoberyl. It is known for its unique ability to change color under different lighting conditions, a phenomenon known as the alexandrite effect. In daylight, alexandrite appears green, while under incandescent light, it shifts to a reddish-purple hue. This color change is due to the presence of trace amounts of chromium in the crystal structure, which absorbs and re-emits light at different wavelengths.
Alexandrite was first discovered in the Ural Mountains of Russia in the 19th century. It was named after Czar Alexander II, who was born on the same day the gem was first found. The stone was highly prized by the Russian nobility, but due to its rarity and the depletion of the original Russian mines, alexandrite is now primarily sourced from other locations around the world. These include Brazil, India, Sri Lanka, Madagascar, and Myanmar. The quality and color change of alexandrite can vary depending on the source, with the most desirable stones exhibiting a strong and distinct color shift.
Each of these gemstones—pearl, moonstone, and alexandrite—has a unique geological origin that contributes to its beauty and value. Whether formed through the slow accumulation of nacre, the interplay of light within feldspar layers, or the rare chemical composition of chrysoberyl, these stones are a testament to the wonders of nature and the earth’s geological processes.
Gemological Properties
Understanding the gemological properties of June’s birthstones—pearl, moonstone, and alexandrite—provides insight into their beauty, durability, and value. Each of these gemstones has distinct physical and chemical characteristics that define their appearance and behavior, making them suitable for different types of jewelry and uses.
| Gemstone | Color | Hardness (Mohs Scale) | Chemical Composition | Transparency | Origin | Special Properties |
|---|---|---|---|---|---|---|
| Pearl | White, cream, pink, black | 2.5–4.5 | Calcium carbonate (CaCO₃), conchiolin | Opaque to translucent | Saltwater (oysters), freshwater (mussels) | Organic gem, forms from nacre secreted by mollusks |
| Moonstone | White, gray, with blue sheen | 6–6.5 | Orthoclase feldspar and albite feldspar | Translucent | India, Sri Lanka, Brazil, USA | Adularescence (glowing sheen) |
| Alexandrite | Green in daylight, red in incandescent light | 8.5–9 | Beryllium-aluminum oxide (BeAl₂O₄) | Transparent to translucent | Russia (original), Brazil, India, Sri Lanka, Madagascar, Myanmar | Alexandrite effect (color change under different light) |
Pearl
Pearls are organic gems, meaning they are formed from living organisms rather than through geological processes. Their primary components are calcium carbonate (CaCO₃) and conchiolin, an organic protein secreted by mollusks. The structure of a pearl consists of concentric layers of nacre, which gives the gemstone its smooth surface and lustrous appearance. The color of pearls can vary widely, including white, cream, pink, and even black, depending on the type of mollusk and the environment in which the pearl is formed.
Pearls are relatively soft, with a hardness of 2.5 to 4.5 on the Mohs scale. This low hardness makes them susceptible to scratches and abrasion, especially when exposed to hard materials or abrasive surfaces. Because of their organic composition, pearls are also sensitive to acids, solvents, and heat. This means that they should be cleaned with care and stored separately from harder gemstones to prevent damage.
Pearls are typically opaque or translucent, and their luster is one of their most distinguishing features. The luster is a result of the way light reflects off the layers of nacre, creating a soft, glowing effect. This property, known as iridescence, is particularly noticeable in high-quality pearls.
Moonstone
Moonstone is a type of feldspar, a group of minerals that make up a significant portion of the Earth’s crust. Its chemical composition is primarily orthoclase feldspar and albite feldspar, which are arranged in alternating layers within the crystal structure. These layers are responsible for the stone’s adularescence, a visual effect that creates a glowing, silvery sheen on the surface of the stone.
Moonstone has a hardness of 6 to 6.5 on the Mohs scale, making it more durable than pearls but still relatively soft compared to other gemstones. It is also prone to cleavage, which means it can split along specific planes when subjected to stress. This property makes moonstone more vulnerable to damage, especially when set in jewelry that is likely to be knocked or bumped.
Moonstone is typically white or gray in color, with a characteristic blue sheen. However, it can also appear in other colors, such as orange, yellow, and green, depending on the type of feldspar and the presence of other minerals. The stone is translucent, allowing light to pass through it and creating the ethereal glow that is associated with moonstone.
Alexandrite
Alexandrite is a rare and highly valued gemstone that is a variety of the mineral chrysoberyl. Its chemical composition is beryllium-aluminum oxide (BeAl₂O₄), and it is known for its unique ability to change color under different lighting conditions. This phenomenon, known as the alexandrite effect, is caused by the presence of trace amounts of chromium in the crystal structure. The chromium absorbs and re-emits light at different wavelengths, resulting in a shift from green in daylight to red in incandescent light.
Alexandrite has a hardness of 8.5 to 9 on the Mohs scale, making it one of the hardest and most durable of June’s birthstones. This high hardness makes it suitable for a variety of jewelry applications, including rings, pendants, and earrings. Unlike pearls and moonstone, alexandrite is not particularly sensitive to light or heat, although it can be affected by exposure to strong acids and solvents.
Alexandrite is typically transparent to translucent and is prized for its clarity and color change. The most desirable alexandrites exhibit a strong and distinct color shift, with a vivid green in daylight and a deep red in incandescent light. The quality of the color change can vary depending on the source, with the most sought-after stones coming from Brazil and India.
Each of these gemstones—pearl, moonstone, and alexandrite—has a unique set of gemological properties that contribute to their beauty and value. Whether through the soft luster of pearls, the ethereal glow of moonstone, or the rare color change of alexandrite, these stones continue to captivate gemstone enthusiasts and jewelers alike.
