June is a month rich in symbolism and natural beauty, represented by a unique set of birthstones that reflect its diversity. Unlike other months, which typically have one or two primary birthstones, June is associated with three official birthstones: Pearl, Moonstone, and Alexandrite. These gemstones each carry their own distinct characteristics, historical significance, and cultural meanings, making them ideal choices for meaningful jewelry. In recent years, Smoky Quartz has also emerged as an alternative birthstone for June, further expanding the options for those seeking a personalized and meaningful gift.
This article explores the rich heritage and gemological properties of June's birthstones, their symbolic meanings, and their role in contemporary jewelry. Whether you are an experienced gemstone enthusiast, a jewelry buyer, or simply curious about the significance of birthstones, this guide offers a comprehensive overview of June’s treasures.
History and Lore
The Origins of June Birthstones
The tradition of associating gemstones with months of the year dates back to ancient times, with early references found in biblical and Roman texts. However, the modern birthstone tradition as we know it began to take shape in the early 20th century. The American National Association of Jewelers (now the Jewelers of America) standardized the list of birthstones in the 1910s, and this list has since been updated to reflect new discoveries and cultural shifts. June was assigned three official birthstones—Pearl, Moonstone, and Alexandrite—due to their historical significance and unique properties.
Pearls: Symbols of Purity and Wisdom
Pearls are among the oldest known gemstones, with their formation process dating back millions of years. They are formed when a foreign particle enters an oyster, mussel, or clam, and the mollusk begins to coat the irritant with layers of nacre, a substance composed of calcium carbonate and conchiolin. This natural process results in a smooth, lustrous surface that has fascinated humans for centuries.
In ancient times, pearls were considered symbols of purity and wisdom. In Greek mythology, they were associated with the goddess of love, Venus (Aphrodite), and were believed to bring beauty, sensuality, and feminine grace. In Chinese culture, pearls were seen as symbols of immortality and were often used in royal jewelry. Over time, pearls became popular in European courts, where they were worn as a sign of status and refinement.
Today, pearls continue to be cherished for their timeless elegance and are often given as gifts to mark significant life events, such as birthdays, anniversaries, and graduations. Their soft, iridescent glow makes them a versatile choice for both casual and formal wear.
Moonstone: A Gemstone of Transformation
Moonstone is a type of feldspar that is known for its ethereal shimmer, or “adularescence,” which creates a soft, milky glow that appears to move across the surface of the stone. This effect is caused by the diffraction of light within the stone’s layered structure and gives moonstone its dreamy, otherworldly appearance.
Historically, moonstone has been associated with the moon and is believed to enhance intuition, emotional balance, and spiritual insight. In ancient India, it was considered a sacred stone and was often worn by royalty. In European folklore, moonstone was believed to protect travelers and promote love and fertility. It was also thought to bring good fortune and was sometimes worn during pregnancy to ensure a safe childbirth.
In modern times, moonstone has gained popularity as a June birthstone due to its calming energy and its ability to reflect the wearer's inner light. It is often used in jewelry such as pendants, earrings, and rings, and is particularly popular in bohemian and minimalist styles.
Alexandrite: A Rare and Color-Changing Gemstone
Alexandrite is one of the rarest and most unique gemstones in the world. It is a type of chrysoberyl that exhibits a color change, appearing green in daylight and red in incandescent light. This remarkable property is due to the presence of trace amounts of chromium in the stone, which alters the way it absorbs and reflects light.
Alexandrite was first discovered in the Ural Mountains of Russia in the 1830s, and it was named after Tsar Alexander II, who was born on the same day that the gemstone was discovered. It quickly became a favorite among European royalty and was considered a symbol of good fortune and intuition. Due to its rarity and striking color change, alexandrite is highly sought after and often reserved for special occasions or high-end jewelry pieces.
Smoky Quartz: A Modern Alternative
While not traditionally considered a birthstone, Smoky Quartz has gained recognition as an alternative birthstone for June. It is a type of quartz that is known for its earthy, golden-brown color and its grounding properties. Smoky Quartz is believed to help remove negative energy, promote emotional stability, and enhance focus and concentration.
As a gemstone, Smoky Quartz is relatively hard (7–7.5 on the Mohs scale) and is often used in rings, pendants, and earrings. Its affordability and versatility have made it a popular choice for those who want a June birthstone with a more contemporary aesthetic.
Geological Formation and Sources
Pearls: Born from the Sea
As an organic gemstone, pearls are formed entirely by living organisms. The process begins when a foreign object—such as a grain of sand or a parasite—enters a mollusk. In response, the mollusk secretes layers of nacre, a substance made of calcium carbonate and conchiolin, around the irritant. Over time, these layers build up to form a pearl.
Natural pearls are extremely rare, as the conditions required for their formation are very specific. Most pearls available in the market today are cultured pearls, which are formed when a small bead or piece of mantle tissue is inserted into a mollusk to stimulate pearl formation. This process was first developed in Japan in the early 20th century and has since been refined in various parts of the world.
Pearls are primarily cultivated in regions with warm, clear water, such as:
- Japan – Known for its freshwater and saltwater pearl farms
- China – A major producer of freshwater pearls
- Australia – Famous for its South Sea pearls, which are large and have a high luster
- Indonesia – Known for producing high-quality akoya and freshwater pearls
The value of a pearl depends on several factors, including its luster, surface quality, shape, size, and color. Pearls with a smooth, even surface and a strong, reflective luster are considered the most valuable.
Moonstone: A Feldspar with a Shimmer
Moonstone is a type of feldspar, a group of minerals that make up a significant portion of the Earth’s crust. It is formed through the slow cooling of magma, which allows the mineral layers to separate and create the unique adularescence effect. This effect is most pronounced in orthoclase feldspar, which is the most common type used in jewelry.
Moonstone is found in several parts of the world, including:
- Sri Lanka – Known for producing the highest quality moonstone with a strong, blue sheen
- India – A major source of moonstone, particularly from the states of Tamil Nadu and Kerala
- United States – Moonstone is found in states such as California, Colorado, and New York
- Brazil – Produces moonstone with a more white or gray sheen
Moonstone is often used in jewelry due to its soft, glowing appearance. However, it is relatively soft (6–6.5 on the Mohs scale), so it requires careful handling to prevent scratches and chips.
Alexandrite: A Rare and Color-Changing Gemstone
Alexandrite is a type of chrysoberyl, a mineral composed of beryllium, aluminum, and oxygen. The color change in alexandrite is due to the presence of chromium, which absorbs light in the green and red parts of the spectrum. In daylight, the stone appears green because it absorbs red light and reflects green light. In incandescent light, which emits more red wavelengths, the stone appears red or purplish-red.
Alexandrite is one of the rarest gemstones in the world due to the specific conditions required for its formation. It is typically found in metamorphic rocks, where heat and pressure have altered the mineral structure of the surrounding rock. The original source of alexandrite was the Ural Mountains in Russia, but most of the world’s alexandrite now comes from Brazil, particularly the state of Minas Gerais.
The rarity and beauty of alexandrite make it a highly prized gemstone. It is often used in high-end jewelry, such as engagement rings, pendants, and earrings, and is considered a symbol of good fortune and intuition.
Smoky Quartz: A Grounding and Versatile Stone
Smoky Quartz is a type of quartz that is characterized by its brown to black color. It is formed when clear quartz is exposed to natural radiation, which causes the stone to develop a golden-brown hue. This radiation can come from surrounding minerals, such as uranium-rich rocks, which emit alpha particles that alter the crystal structure of the quartz.
Smoky Quartz is found in various parts of the world, including:
- Brazil – One of the largest producers of high-quality Smoky Quartz
- Switzerland – Known for producing some of the finest Smoky Quartz in the world
- Madagascar – A major source of Smoky Quartz, particularly in the Anosy region
- United States – Smoky Quartz is found in states such as Colorado and California
Smoky Quartz is a relatively hard gemstone (7–7.5 on the Mohs scale), making it suitable for use in a wide range of jewelry styles, including rings, pendants, and earrings.

| Gemstone | Hardness (Mohs Scale) | Chemical Composition | Refractive Index | Color | Cleavage |
|---|---|---|---|---|---|
| Pearl | 2.5–4.5 | Calcium carbonate (CaCO₃) and conchiolin | 1.50–1.68 | White, pink, black, or multicolored | No cleavage; brittle |
| Moonstone | 6–6.5 | Feldspar (KAlSi₃O₈) and sodium-rich feldspar (NaAlSi₃O₈) | 1.518–1.526 | White, gray, or blue sheen | No cleavage; brittle |
| Alexandrite | 8.5–9 | Beryllium aluminum oxide (BeAl₂O₄) | 1.74–1.76 | Green in daylight, red in incandescent light | No cleavage; tough |
| Smoky Quartz | 7–7.5 | Silicon dioxide (SiO₂) | 1.48–1.55 | Brown to black | No cleavage; tough |
Pearl
Pearls are relatively soft (2.5–4.5 on the Mohs scale), which makes them susceptible to scratches and abrasions. They are composed of calcium carbonate (CaCO₃) and conchiolin, a protein that binds the layers of nacre together. The refractive index of pearls ranges from 1.50 to 1.68, which contributes to their soft, iridescent luster.
Because pearls are organic and relatively brittle, they require special care to maintain their luster and prevent damage. They should be kept away from harsh chemicals, excessive heat, and abrasive surfaces.
Moonstone
Moonstone has a moderate hardness (6–6.5 on the Mohs scale), which makes it more durable than pearls but still relatively soft compared to other gemstones. Its chemical composition includes potassium aluminum silicate (KAlSi₃O₈) and sodium aluminum silicate (NaAlSi₃O₈), which form the layered structure that creates its unique adularescence effect.
Moonstone’s refractive index is between 1.518 and 1.526, and its color can vary from white and gray to a soft blue sheen. Due to its brittleness and lack of cleavage, moonstone should be handled carefully to avoid chipping or cracking.
Alexandrite
Alexandrite is one of the hardest June birthstones, with a hardness of 8.5–9 on the Mohs scale. It is composed of beryllium aluminum oxide (BeAl₂O₄), which gives it its unique color change property. The refractive index of alexandrite ranges from 1.74 to 1.76, and its color shifts from green in daylight to red in incandescent light due to the presence of chromium.
Alexandrite does not have cleavage and is relatively tough, making it suitable for use in rings and other types of jewelry that are worn daily. However, due to its rarity and high value, it is often reserved for special occasions or high-end pieces.
Smoky Quartz
Smoky Quartz is a durable gemstone with a hardness of 7–7.5 on the Mohs scale. It is composed of silicon dioxide (SiO₂), which is the same chemical composition as clear quartz. The refractive index of Smoky Quartz ranges from 1.48 to 1.55, and its color varies from brown to black, depending on the amount of natural radiation it has been exposed to.
Smoky Quartz does not have cleavage and is relatively tough, making it suitable for use in a wide range of jewelry styles. It is also relatively affordable compared to other gemstones, which makes it a popular choice for those who want a June birthstone with a more contemporary aesthetic.
