About May's Birthstone

Emerald, the birthstone for May, is one of the most precious and coveted gemstones in the world. Known for its lush green color, emerald is a variety of the mineral beryl colored by trace amounts of chromium and sometimes vanadium.

The name "emerald" comes from the ancient Greek word "smaragdus," meaning "green gem." Throughout history, emeralds have been treasured by royalty and the elite, from Cleopatra of Egypt to the Mughal emperors of India. The Incas and Aztecs of South America, where some of the finest emeralds are still found, also revered the stone.

As the May birthstone, emerald is believed to bring wisdom, growth, and patience to those born in this month. It's also traditionally given as a gift for the 20th and 35th wedding anniversaries, symbolizing the enduring nature of love and commitment.

The Rich History of Emerald

Emeralds have a fascinating history that spans over 4,000 years. Ancient civilizations in Egypt, India, and Babylon all treasured emeralds. Cleopatra was known for her passion for emeralds and claimed ownership of all emerald mines in Egypt during her reign. These "Cleopatra's Mines" were actually rediscovered in the early 19th century near the Red Sea.

In ancient Rome, emeralds were dedicated to Venus, the goddess of love and beauty. The Roman author Pliny the Elder wrote in the first century CE that "nothing greens greener" than an emerald, and that the stone's color was more pleasant than green plants and leaves.

The Spanish conquest of the New World in the 16th century led to the discovery of emerald mines in Colombia, which still produce some of the finest emeralds in the world today. The Mughal emperors of India, particularly Shah Jahan (who built the Taj Mahal), were known for their love of emeralds, often having sacred texts inscribed on them.

Throughout history, emeralds have been believed to have mystical powers, including the ability to reveal truth, protect against evil spells, cure diseases, and even predict the future. Today, emeralds remain one of the "Big Four" precious gemstones, alongside diamonds, rubies, and sapphires.

Emerald Varieties

While emeralds are defined by their green color, there are several varieties and quality factors that distinguish different types of this precious gemstone:

Colombian Emeralds

Considered the finest in the world, Colombian emeralds are known for their pure, vibrant green color with a slight bluish tint. The mines at Muzo, Chivor, and Coscuez produce emeralds with distinctive characteristics.

Zambian Emeralds

These emeralds typically have a deeper, more bluish-green color than Colombian stones. They often have fewer inclusions and better clarity, making them increasingly popular in the market.

Brazilian Emeralds

Brazilian emeralds often have a lighter, more yellowish-green color. They tend to have better clarity than Colombian emeralds but may lack the same intensity of color.

Trapiche Emeralds

A rare and unique variety that displays a six-rayed star pattern resembling a wheel. These emeralds form when black carbon impurities create a spoke-like pattern during crystal growth.

Cat's Eye Emeralds

Extremely rare emeralds that exhibit chatoyancy (the cat's eye effect). These stones are usually cut as cabochons to showcase the moving light band across the surface.

Ethiopian Emeralds

A relatively new discovery, Ethiopian emeralds have entered the market in recent years. They often have excellent clarity and a bright green color similar to Colombian emeralds.

Fascinating Facts About Emerald

Jardin Inclusions

Almost all emeralds have inclusions visible to the naked eye. These inclusions are poetically called "jardin" (garden in French) because they resemble moss or foliage. These "gardens" are considered part of the character of emeralds.

Emerald Cut

The rectangular step-cut with truncated corners known as the "emerald cut" was developed specifically for emeralds to protect them from pressure and impact during cutting, due to their relatively fragile nature.

Cleopatra's Passion

Cleopatra was so passionate about emeralds that she claimed ownership of all emerald mines in Egypt during her reign. She often wore emeralds as part of her royal adornment and gave them as gifts to important dignitaries.

The Chalk Emerald

One of the most famous emeralds in the world, the Chalk Emerald, weighs 37.8 carats and is renowned for its exceptional clarity and color. It's now housed at the Smithsonian National Museum of Natural History.

Emerald in Jewelry

Emeralds have been prized in jewelry for thousands of years, and their rich green color continues to captivate jewelry designers and wearers alike. Here are some popular ways emeralds are used in jewelry:

Popular Settings

  • Rings: Emeralds make stunning center stones for engagement rings and statement rings, often set in protective bezel or halo settings.
  • Earrings: From simple studs to elaborate chandelier designs, emerald earrings create a striking look that complements many skin tones.
  • Necklaces: Emerald pendants and beaded necklaces showcase the stone's rich color, with larger stones often used as focal points in important pieces.
  • Bracelets: Tennis bracelets and bangles featuring emeralds create elegant accessories that add a touch of luxury to any outfit.

Styling Tips

  • Emeralds pair beautifully with both yellow and white metals, though yellow gold often enhances the warmth of the green color.
  • For a complementary color scheme, pair emeralds with diamonds or pearls for a classic look.
  • Emeralds look particularly striking against black, white, or neutral-colored clothing, allowing the rich green color to stand out.
  • For a modern twist, look for emeralds in contemporary settings or mixed with unexpected gemstones like pink sapphires or tanzanite.

Care Tips for Emerald Jewelry

  • Clean emerald jewelry gently with mild soap and warm water using a soft brush.
  • Avoid ultrasonic cleaners and steam cleaning, which can damage emeralds due to their potential inclusions and fractures.
  • Remove emerald jewelry before engaging in sports, household chores, or any activity that might subject the stone to impact or harsh chemicals.
  • Store emerald pieces separately from harder gemstones to prevent scratching, ideally in a soft cloth or padded jewelry box.
