May Birthstone Emerald: Meaning & the 4 Cs

Emerald: The Blossoming Birthstone of May

Emerald, the May birthstone and a prevalent gemstone in today’s market, boasts a rich history that may surprise you. As the most celebrated variety of beryl, this gemstone is represented here by a natural rough beryl and a beautifully cut 1.07 ct Colombian emerald.

The name “emerald” originates from the Ancient Greek word “Smaragdos,” which translates to “green gem.” This stunning stone has captivated people since at least 330 BC. The earliest recorded emerald mines were located in Egypt, specifically in the Zabara foothills and near El Quseir, remaining active from 330 BC until the 1700s.

While Egypt is often associated with the origins of emeralds, these exquisite stones are found in various parts of the world. Notable sources include Madagascar, Pakistan, Russia, Afghanistan, Zimbabwe, and even some northern states in the United States. However, the largest and most commercially significant emerald mines today are situated in Zambia, Brazil, and Colombia. Colombian emeralds, first discovered in the late 1500s by Spanish explorers in the Muzo region. They swiftly began to export the unique gemstone to Europe, where they quickly gained popularity due to their strikingly vibrant green hue and impressive clarity.

So, why is emerald the May birthstone? This gem embodies renewal and growth, symbolising the essence of springtime—a perfect fit for this blossoming month.

What Is the May Birthstone?

The May birthstone is emerald, the green to bluish-green variety of the mineral beryl. Its colour comes from trace amounts of chromium and, in some stones, vanadium. Emerald sits alongside diamond, ruby and sapphire as one of the four traditional precious gemstones, and it is also the gem traditionally given to celebrate 20th and 35th wedding anniversaries.

May Birthstone Meaning and Symbolism

For centuries, the May birthstone has been linked with rebirth, love and wisdom. The ancient Romans associated emerald with Venus, the goddess of love and beauty, while Cleopatra was famously passionate about the gem and wore it in her royal adornments. Legend also held that emerald could sharpen the mind and bring good fortune to its wearer, which helps explain why it remains such a meaningful gift for anyone born in May.

The 4 Cs of a May Birthstone Emerald

Like diamonds, emeralds are judged on four key quality factors:

Colour: the most important factor. The finest emeralds show a pure green to bluish-green hue with vivid, even saturation.
Clarity: most emeralds contain visible inclusions, affectionately known as the “jardin” (French for garden). Eye-clean stones are exceptionally rare.
Cut: the rectangular step cut is so closely tied to this gem that it is simply called the “emerald cut”. It shows off the colour while protecting the corners of the stone.
Carat: fine-quality emeralds become much rarer as size increases, so the price per carat climbs steeply for larger stones.

How to Care for Your May Birthstone

Emerald rates 7.5 to 8 on the Mohs scale of hardness, so it is durable enough for jewellery but more vulnerable to scratches and knocks than diamond. Most emeralds are also treated with oils or resins to improve their apparent clarity, which means ultrasonic cleaners, steam cleaners and harsh chemicals are best avoided. Instead, clean your emerald gently with lukewarm soapy water and a soft brush, and always ask whether a stone has been treated before you buy.
