Whether you're a gemstone enthusiast, a jewelry buyer, or simply someone curious about the meanings behind these natural wonders, this guide will offer a comprehensive and insightful look into the world of June's birthstones.
History and Lore
The Timeless Beauty of Pearls
Pearls have been cherished for thousands of years, with their origins tracing back to 2300 BC in ancient China, where freshwater pearls were revered by Chinese royalty as symbols of purity and honesty. These organic gems, formed within mollusks, are unique in that they are the only gemstones not formed from minerals within the earth. Instead, they develop naturally within the soft tissue of mollusks such as oysters and mussels.
In Indian traditions, pearls were associated with health and fertility, while in the Middle East, they were seen as heaven’s teardrops. The Ancient Romans, who considered pearls the ultimate symbol of wealth and status, even restricted their wearing to the ruling classes, with Julius Caesar enforcing such a decree.
Pearls have remained a popular choice for jewelry across cultures and centuries, often symbolizing grace, wisdom, and inner beauty. Their smooth, lustrous appearance and soft, white hues have made them a favorite in both traditional and contemporary designs.
The Mystical Glow of Moonstone
Moonstone, named for its ethereal, moon-like glow, has long been associated with femininity, intuition, and emotional balance. This gemstone is best known for its iridescent sheen, which is the result of light reflecting off layers within the stone. To properly showcase this phenomenon, known as adularescence, moonstone must be cut as a cabochon—a smooth, rounded shape without facets.
Among American First Nations, moonstone was believed to appear on the shore only under specific celestial conditions, occurring approximately every 21 years. This rare event gave rise to the phrase “once in a blue moon.” Moonstone was also treasured for life and was often buried with the deceased as an amulet for the afterlife.
In the Far East, moonstone was considered a gem of good fortune, and its shimmering light was viewed as a symbol of the living spirit. In India, it was particularly sacred and believed to ignite passion and love while offering protection to sea travelers.
The Color-Changing Wonder of Alexandrite
Alexandrite is the most modern of the June birthstones, having only been discovered in the 19th century and gaining recognition much later. Named after Tsar Alexander II of Russia, this rare gem is known for its dramatic color change, famously described as “emerald by day, ruby by night.” Under daylight or fluorescent light, alexandrite appears green or bluish-green, while under incandescent or candlelight, it shifts to a deep red or purplish hue.
This phenomenon is due to the gemstone’s pleochroic nature, meaning it exhibits different colors depending on the angle of light and the viewer's perspective. Alexandrite is a type of chrysoberyl, a mineral known for its exceptional hardness and durability, with a Mohs hardness rating of 8.5, making it one of the hardest natural gemstones.
Historically, alexandrite was considered a symbol of good fortune and was believed to bring success and adaptability to those who wore it. Its rarity and unique properties have made it a highly sought-after gem in both antique and contemporary jewelry collections.
Geological Formation and Sources
Pearls: The Organic Gem
Pearls form when a foreign object, such as a grain of sand or a parasite, enters the soft tissue of a mollusk like an oyster or mussel. In response, the mollusk secretes layers of nacre, a crystalline substance composed primarily of calcium carbonate and conchiolin, to coat the irritant. Over time, these layers build up to form a pearl.
Pearls can be natural—formed without human intervention—or cultured, which means they are nucleated with a bead or piece of mantle tissue and allowed to grow under controlled conditions. Freshwater pearls are typically found in rivers and lakes, while saltwater pearls come from oceanic oysters.
Major sources of high-quality pearls include:
- Japan (especially for saltwater Akoya pearls)
- China (freshwater pearls)
- Australia and Tahiti (for black pearls)
- Indonesia and the Philippines (for golden and pink pearls)
Moonstone: A Feldspar's Luminous Glow
Moonstone belongs to the feldspar group of minerals, specifically the orthoclase-potassium feldspar family. The iridescent sheen known as adularescence occurs due to the refraction of light between layers of feldspar and albite within the stone. This gives moonstone its soft, shimmering glow, which is most visible in a cabochon cut.
Natural moonstone is found in various parts of the world, including:
- Sri Lanka (known for high-quality moonstone)
- India and Nepal
- Madagascar and Brazil
- The United States (especially in Virginia and North Carolina)
Sri Lankan moonstone is particularly prized for its blue sheen, which is often the most vivid and desirable in the gem trade.
Alexandrite: The Rare Color-Change Gem
Alexandrite is a rare variety of chrysoberyl, a mineral composed of beryllium aluminum oxide (BeAl₂O₄). Its color-changing property is due to trace amounts of chromium in the crystal structure, which absorbs and re-emits light differently under various light sources.
True alexandrite is extremely rare, and most commercially available alexandrite on the market is either treated to enhance its color change or synthetically produced in a laboratory. Natural alexandrite is primarily found in:
- Brazil (the current largest source)
- India, Madagascar, and Russia (the original discovery site)
- Mozambique and Nigeria
Brazilian alexandrite is particularly valued for its strong color change and high clarity, although it is typically less green than the classic Russian specimens.
Gemological Properties
Pearl
| Property | Description |
|---|---|
| Type | Organic gemstone |
| Composition | Calcium carbonate (aragonite) and conchiolin |
| Hardness | 2.5–4.5 on the Mohs scale |
| Luster | Waxy to silky |
| Color | White, cream, pink, silver, black |
| Transparency | Translucent to opaque |
| Cut | Bead, drop, button, and freeform |
Pearls are soft and porous, making them sensitive to heat, chemicals, and abrasion. They require gentle care to preserve their luster and integrity.
Moonstone
| Property | Description |
|---|---|
| Type | Feldspar mineral |
| Composition | Potassium aluminum silicate |
| Hardness | 6–6.5 on the Mohs scale |
| Luster | Waxy to greasy |
| Color | White, pink, blue, gray |
| Transparency | Translucent to semi-transparent |
| Cut | Cabochon only |
Moonstone is best admired when cut as a cabochon to showcase its adularescence. It is relatively tough but can be brittle, so it should be handled with care.
Alexandrite
| Property | Description |
|---|---|
| Type | Chrysoberyl |
| Composition | Beryllium aluminum oxide (BeAl₂O₄) |
| Hardness | 8.5 on the Mohs scale |
| Luster | Vitreous |
| Color | Green by day, red by night |
| Transparency | Transparent to translucent |
| Cut | Faceted or cabochon, depending on the desired effect |
Alexandrite is very hard and durable, making it suitable for daily wear. However, its pleochroism means it must be cut precisely to highlight its color change.
