May Birthstone
Emerald
The birthstone of rebirth, love, and wisdom — treasured for over 4,000 years
Quick answer: The birthstone for May is Emerald.
Emerald is both the modern and traditional birthstone for May, celebrated for its vivid green color, royal heritage, and enduring reputation as a symbol of love and renewal.
What Is the Birthstone for May?
The May birthstone is emerald. One of the four precious gemstones alongside diamond, ruby, and sapphire, emerald has been prized for over 4,000 years for its magnificent green color and powerful symbolism. It is a variety of the mineral beryl, colored by trace amounts of chromium and sometimes vanadium.
The name "emerald" traces back through Old French and Latin to the Greek smaragdos, simply meaning "green gem." Cleopatra famously claimed ownership of every emerald mine in Egypt, adorning herself with the stones as symbols of power and eternal youth. The Roman author Pliny the Elder declared that nothing was greener than an emerald.
Today emerald remains one of the most sought-after gemstones in the world, making it a treasured May birthday gift and a centerpiece in fine jewelry collections everywhere.

Why Is Emerald the May Birthstone?
Emerald's association with May is rooted in the gemstone's deep connection to spring and renewal. As the Northern Hemisphere bursts into green in May, no stone captures that transformation more perfectly than emerald. Ancient cultures linked the gem to fertility goddesses and the cycle of rebirth that defines this time of year.
The modern birthstone list was officially standardized in 1912 by the American National Association of Jewelers (now Jewelers of America). They formalized emerald as the May birthstone — a choice that honored millennia of tradition. Emerald had appeared on birthstone lists tracing back to the biblical Breastplate of Aaron and to early Hindu and Arabic gemological traditions.
Emerald connects naturally to both May zodiac signs: Taurus values its grounding abundance and earthly beauty, while Gemini appreciates its link to communication, intellectual clarity, and adaptability.
The History of Emerald
Emerald mining dates back to at least 1500 BCE in Egypt, where Cleopatra's legendary passion for the green gem made it a symbol of royal power. Egyptian emerald mines near the Red Sea — later called "Cleopatra's Mines" — operated for centuries, supplying the ancient Mediterranean world.
The Incas and Aztecs of South America revered emerald long before the arrival of Europeans. When the Spanish conquistadors reached the New World in the 16th century, they discovered Colombian emerald deposits of extraordinary quality. These mines at Muzo, Chivor, and Coscuez would go on to supply the world's finest emeralds for centuries.
The Mughal emperors of India, particularly Shah Jahan — builder of the Taj Mahal — were passionate collectors of emeralds. They inscribed sacred texts onto large emerald tablets and set the stones into elaborate jewelry and ceremonial objects. The famous "Mogul Emerald," a 217.80-carat tablet inscribed with prayers, dates to 1695.
In medieval and Renaissance Europe, emeralds were believed to cure diseases, reveal truth, and protect against evil enchantments. They were a favorite of the clergy, who wore them as symbols of faith and moral purity. Today emerald remains one of the four precious gemstones and continues to be mined primarily in Colombia, Zambia, Brazil, and Ethiopia.

How to Care for Emerald Jewelry
Emerald requires gentler care than harder gemstones due to its natural inclusions. Follow these guidelines to keep your emerald brilliant:
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.
Avoid exposure to harsh chemicals and solvents.
Avoid sudden temperature changes.
Store separately to prevent scratching other gemstones.
Remove emerald jewelry before engaging in sports, household chores, or any activity that might subject the stone to impact.
How to Choose Emerald Jewelry
When shopping for emerald jewelry, color is the single most important factor. Look for stones with vivid, saturated green — the richer the hue, the more valuable the gem. A slight bluish-green tint (typical of fine Colombian emeralds) is highly prized.
- 1. Color first: Vivid, evenly saturated green with medium-to-dark tone is most desirable. Avoid overly light or yellowish stones.
- 2. Clarity: Some inclusions are expected and acceptable. Aim for stones where the "jardin" does not severely affect transparency or structural integrity.
- 3. Cut: The classic emerald cut (rectangular step cut) was invented for this stone. Oval, round, and pear shapes are also popular.
- 4. Setting: Bezel or halo settings offer the best protection for emerald's natural fragility in rings worn regularly.
Fascinating Facts About Emerald
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.
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 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.
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.
