The following sections will explore each gemstone in depth, covering their geological origins, symbolic meanings, and practical considerations for care and selection.
History and Lore
Pearl
Pearls have been revered for thousands of years, with records of their use dating back to ancient civilizations. The ancient Romans associated pearls with Venus, the goddess of love and beauty, believing they were formed from the tears of the gods. In Chinese mythology, pearls were thought to originate from the brain of a dragon, a symbol of wisdom and power.
The allure of pearls lies in their organic origin—they are formed within the soft tissue of mollusks such as oysters and mussels. Unlike other gemstones, pearls are not found in rocks but are secreted as a byproduct of the mollusk’s natural defense mechanism. When a foreign object, such as a grain of sand, enters the mollusk’s shell, it coats the irritant with layers of nacre, a substance that creates the pearl’s lustrous surface.
Pearls have long been associated with purity, innocence, and elegance, making them a popular choice for bridal jewelry and other symbolic occasions. Their soft, white or cream color and smooth surface have also made them a timeless favorite in fashion and jewelry design.
Alexandrite
Alexandrite is a rare and modern addition to the June birthstone list, officially recognized in 1950. It is named after Tsar Alexander II of Russia, and its discovery is often attributed to the 19th century in the Ural Mountains of Russia. What sets alexandrite apart is its chameleon-like color-changing ability—it appears green or blue in daylight and red or purple under incandescent light.
This unique property is due to the presence of chromium, a trace element that affects how the stone absorbs and reflects light. Alexandrite is also known for its rarity, as high-quality specimens are extremely difficult to find.
In many cultures, alexandrite is believed to bring good luck, strength, and adaptability. Because of its color change, it is also associated with transformation and balance, making it a powerful stone for personal growth and emotional resilience.
Moonstone
Moonstone is the traditional June birthstone, first recognized in 1912. Its most distinctive feature is its iridescent sheen, known as adularescence, which gives the stone a soft, glowing appearance reminiscent of moonlight. This effect is caused by the way light interacts with the stone’s layered structure, where alternating layers of feldspar minerals reflect light in a shimmering pattern.
Historically, moonstone has been connected to lunar energy and divine femininity. In ancient times, it was believed to be formed from moonlight itself and was associated with protection, love, and emotional balance. The stone is also considered a symbol of intuition and spiritual awareness, making it popular among those seeking to enhance their inner wisdom and connect with their emotions.
In modern times, moonstone is often used in spiritual and emotional healing practices, and it is favored for its calming and nurturing energy.
Geological Formation and Sources
Pearl
Pearls are organic gemstones, meaning they are formed through biological processes rather than geological ones. They are produced by mollusks, including saltwater oysters and freshwater mussels. The process of pearl formation begins when a foreign object, such as a grain of sand or a parasite, enters the mollusk’s shell. In response, the mollusk coats the irritant with nacre, a substance composed primarily of calcium carbonate and conchiolin.
Natural pearls are extremely rare, as they form without human intervention. Most pearls available today are cultured pearls, which are created by intentionally introducing a bead or mantle tissue into the mollusk to stimulate pearl formation. This process was first developed in Japan in the early 20th century and has since become the standard method for pearl production.
Major sources of pearls include:
- Japan (for Akoya pearls)
- China (for freshwater pearls)
- Australia (for South Sea pearls)
- Indonesia (for Keshi pearls)
Pearls are known for their smooth texture, luster, and soft colors, which range from white and cream to pink, lavender, and black.
Alexandrite
Alexandrite is a rare mineral in the chrysoberyl family, and it is distinguished by its color-changing properties. The stone is composed of beryllium aluminum oxide (BeAl₂O₄) and contains chromium, which gives it its unique color shift.
Alexandrite is typically found in granitic pegmatites and metamorphic rocks, and it is most commonly mined in:
- Brazil (the largest source today)
- India
- Nepal
- Madagascar
- Russia (the original source)
Because of its rarity and beauty, alexandrite is often referred to as the "emerald by day and ruby by night". High-quality alexandrite is extremely valuable, especially when it displays a clean, color-change effect and has a high refractive index.
Moonstone
Moonstone is a type of feldspar mineral, and it is most commonly found in granitic and metamorphic rocks. The adularescence (the glowing sheen) is caused by the interference of light with the stone’s layered structure, which consists of alternating layers of orthoclase and albite feldspar.
Major sources of moonstone include:
- Sri Lanka (known for high-quality moonstone with a strong adularescence)
- India
- United States (particularly in Georgia and New York)
- Myanmar
- Brazil
Moonstone is typically white or cream-colored with a bluish or rainbow sheen, but it can also occur in pink, peach, grey, and blue varieties. The stone is relatively soft, with a Mohs hardness of 6 to 6.5, which means it requires gentle handling and care.
Gemological Properties
The following table summarizes the key gemological properties of the three June birthstones:
| Property | Pearl | Alexandrite | Moonstone |
|---|---|---|---|
| Origin | Organic, formed in mollusks | Inorganic, from granitic pegmatites | Inorganic, from feldspar rocks |
| Chemical Formula | Calcium carbonate (CaCO₃) + conchiolin | BeAl₂O₄ (beryllium aluminum oxide) | KAlSi₃O₈ (orthoclase feldspar) |
| Hardness (Mohs) | 2.5–4.5 | 8.5 | 6–6.5 |
| Color | White, cream, pink, black | Green/blue in daylight, red/purple in incandescent light | White, cream, pink, blue, rainbow sheen |
| Transparency | Usually translucent to opaque | Transparent to translucent | Translucent |
| Luster | Waxy, nacreous | Vitreous | Vitreous, with adularescence |
| Cleavage | None (organic) | None | None |
| Specific Gravity | 2.6–2.8 | 3.7–3.9 | 2.55–2.58 |
| Refractive Index | 1.50–1.68 | 1.74–1.78 | 1.518–1.526 |
| Common Cuts | Round, drop, button | Emerald, round, cushion | Round, oval, cabochon |
These properties influence how each stone is used in jewelry and how it should be cared for. For example, pearls are soft and can be easily scratched, so they should be stored separately from harder gemstones. Alexandrite, being very hard, is more durable and suitable for everyday wear, while moonstone is also relatively soft and requires gentle cleaning.
