The Emerald
Laid Bare

What Is the May Birthstone?

The birthstone for May is emerald, a variety of the mineral beryl prized for its vivid green color and place among the four precious gemstones alongside diamond, ruby, and sapphire.

Emerald has been recognized as the May birthstone for over a century, with the National Association of Jewelers formalizing the modern birthstone list in 1912. However, its connection with spring and renewal stretches back thousands of years.

Emerald's signature green comes from trace amounts of chromium and vanadium within the beryl crystal structure. Each stone contains natural inclusions called jardin, French for "garden," creating tiny internal landscapes that give every emerald a unique fingerprint.

Rather than being considered flaws, these inclusions are part of what makes each emerald distinctive. They help reveal the natural character of the gemstone and separate emerald from other green gemstones.

With a hardness of 7.5 to 8 on the Mohs scale, emerald is durable enough for regular wear. However, this May birthstone emerald benefits from mindful care to preserve its beauty over time.

Emerald has been treasured by Egyptian pharaohs, Roman emperors, Inca rulers, and modern collectors alike. It remains one of the most admired gemstones, with a history spanning more than 5,000 years.

May Birthstone Meaning & Symbolism

Renewal, Love, and Truth

Emerald has been called the stone of Venus, the Roman goddess of love, and ancient cultures believed it could reveal a lover's true intentions.

Some legends held that placing an emerald under the tongue granted the ability to foresee the future, while others claimed it could expose false promises and cure diseases of the heart.

In Hindu tradition, the gem is connected to the heart chakra, making it a symbol of compassion and emotional balance.

Across cultures, emerald has been associated with growth, fertility, wisdom, and the renewing energy of spring. These meanings make it a natural birthstone for May and a meaningful choice for May birthstone jewelry.

Foresight, Eloquence, and Intelligence

Beyond love and renewal, historical traditions credited emerald with sharpening the mind.

Roman naturalist Pliny the Elder wrote that gem cutters rested their eyes by gazing at emeralds after hours of detailed work, believing the stone was restorative.

Medieval scholars considered emerald a symbol of eloquence, wisdom, and intellectual clarity. These qualities helped make the gemstone a favorite among rulers, advisors, and collectors throughout history.

The 20th and 35th Anniversary Stone

Emerald is the traditional gemstone for the 20th and 35th wedding anniversaries , representing relationships that have matured with depth and endurance.

Beyond anniversary celebrations, emerald also makes a meaningful choice for Mother's Day, May birthdays, graduations, and other moments that represent growth, renewal, or new beginnings.

The History of the May Birthstone

The earliest known emerald mines date to approximately 1500 BCE in Upper Egypt near the Red Sea, later known as "Cleopatra's Mines."

The Egyptian queen claimed ownership of every emerald mine in the realm, adorning herself and her palace with the gem she considered a symbol of eternal life. Emerald was buried with pharaohs as a protective talisman for the afterlife.

The name emerald traces back through Old French esmeralde and Latin smaragdus to the Greek smaragdos, meaning "green gem."

In Rome, emerald became a favored stone of the elite. Pliny the Elder dedicated extensive passages to the gem, noting that "nothing greens greener" and that Roman gem cutters rested their eyes on emeralds after hours of detailed work.

When Spanish conquistadors reached South America in the 16th century, they discovered Muzo and Chivor emeralds of extraordinary quality. These Colombian emeralds helped establish the region as one of the world's most important sources of premium emerald gemstones.

The Incas had been using emerald in jewelry and religious ceremonies for at least 500 years before European contact.

These Colombian emeralds became, and remain, the benchmark against which many other emeralds are measured.

In 1912, the National Association of Jewelers designated emerald as the sole birthstone for May, formalizing an association that had existed for centuries.

When birthstone traditions became popular in the 16th century, both emerald and agate were associated with May. Over time, emerald became the recognized May birthstone emerald.

May Birthstone Color

Emerald's color ranges from yellow-green to blue-green, with the most valued stones displaying a vivid, saturated green with a slight blue undertone and medium to medium-dark tone.

The distinctive color of the May birthstone comes from trace amounts of chromium, vanadium, and iron. Chromium is the primary color contributor in many Colombian emeralds, while vanadium influences Brazilian stones and iron contributes to the bluish tones found in some Zambian emeralds.

The finest emeralds appear intensely green in both natural and artificial light. In emerald grading, color saturation often matters more than clarity. A richly colored stone with visible inclusions may be more valuable than a pale, eye-clean emerald.

The term "jardin" acknowledges that inclusions are expected and even desired. They create an internal garden that proves the stone's natural origin.

Unlike diamonds, which are graded under 10x magnification, emeralds are graded for clarity with the naked eye.

If no inclusions are visible without magnification, the stone is considered "eye-clean," which is a relatively rare characteristic among natural emeralds.

Where May Birthstone Emeralds Come From

Few gemstones are as geographically distinctive as emerald.

The conditions required to produce gem-quality emeralds are extremely rare. They require beryllium-rich geological environments combined with chromium or vanadium-bearing host rocks.

Three countries dominate world production, each creating emeralds with distinct color profiles.
