There is a specific shade of green that doesn't quite exist anywhere else. Not in glass, not in paint, not in any other gemstone. It's a green that seems to hold light rather than reflect it, and for thousands of years, people who first laid eyes on it have used the same word: alive.
Cleopatra collected them. The Inca considered them sacred. The Spanish royal family kept them locked in vaults for generations. A surprising number of the world's most famous green stones share the same origin story, and they share something else, too.
They are all emeralds, the official birthstone for May.

A Brief History of Emerald
Emerald has held its place on the modern birthstone list since 1912, when the National Association of Jewelers, now Jewelers of America, standardized the assignments still in use today.
More than 4,000 years ago, emeralds have been mined and traded for more than 4,000 years. Ancient Egyptians prized them so highly that Cleopatra became closely associated with the stone, reportedly wearing and collecting emerald jewellery throughout her reign. According to the Gemological Institute of America (GIA), the so-called Cleopatra's Mines remained active well into the 1700s.
Even Cleopatra herself was famously fond of emeralds. She gifted them to visiting dignitaries, sometimes engraved with her own likeness.
Half a world away, the Inca and Aztec civilizations of South America held emeralds sacred long before the Spanish arrived in the 16th century. When the conquistadors discovered Colombia's emerald deposits, they began shipping the stones across global trade routes, and the gem entered Europe and Asia in volumes the world had never seen. Brazil joined the modern emerald map in the 1960s. Zambia rose as a major producer earlier, in the 1920s.
Over time, emeralds appeared in crowns, ceremonial jewellery, and heirloom collections across cultures, where they became symbols of status and power.
What Does Emerald Symbolize?
Emerald has always been tied to growth. Not the loud, dramatic kind, but the kind that happens quietly over time: confidence settling in, clarity sharpening, relationships deepening, priorities changing.
That connection is part of why the stone feels so closely linked to May. Everything is in transition. Winter has fully passed, summer is approaching, and the world starts looking alive again.
✓ Growth & Renewal
For centuries, emerald has symbolized rebirth, renewal, and forward movement. Ancient cultures associated its green colour with fertile land, nature, and life itself.
Even today, emerald often represents a new chapter: a birthday, a career milestone, an engagement, or a personal reset. It is a stone people tend to choose during periods of change.
✓ Love & Loyalty
Emerald has also long been connected to love, honesty, and emotional balance. In some traditions, it was believed to strengthen trust between partners and encourage deeper connection.
Unlike gemstones chosen purely for sparkle, emerald tends to feel more personal. Less performative. More intentional. That may be part of its lasting appeal.
✓ Wisdom & Clarity
Historically, emerald was associated with intelligence, intuition, and truth. Some believed the stone could sharpen thinking or help people see situations more clearly.
Whether or not you believe in gemstone symbolism, there is something undeniably calm about emerald's colour. It draws attention without being loud about it.
✓ A Stone With Presence
Emerald jewellery often appeals to people who prefer substance over excess. People are drawn to rich colour, natural character, and pieces that feel distinctive without trying too hard.
It is bold, but not flashy. Classic, but never boring. And unlike trends that cycle in and out every few years, emerald has never really disappeared.
What Colour Is Emerald?
Emerald belongs to the beryl mineral family, but its colour is what sets it apart.
The gemstone ranges from soft grassy green to deep bluish-green, though the most valuable emeralds usually display a vivid, saturated green with even colour throughout the stone.
Unlike diamonds, where clarity often dominates value, emeralds are judged primarily by colour. Inclusions are common and expected. In fact, most natural emeralds contain internal fractures and patterns often referred to as jardin, the French word for “garden.”
These inclusions are not always considered flaws. In many cases, they are part of what makes a natural emerald recognizable and unique.
Emerald's Physical Properties
Emerald ranks between 7.5 and 8 on the Mohs hardness scale, making it durable enough for jewellery but still more delicate than gemstones like diamonds or sapphires.
Most emeralds contain natural inclusions, which can make them more vulnerable to impact or pressure. Because of this, jewellers often cut emeralds into shapes that help protect the stone. The classic emerald cut, with its rectangular shape and step-cut facets, was designed specifically for that purpose.
Most emeralds on the market are also treated with oils or resins to improve clarity. This is considered standard industry practice and should always be disclosed by the jeweller.

How to Choose Emerald Jewellery
Buying emerald jewellery is different from buying diamonds. With emeralds, perfection is not really the goal.
Character is.
The best pieces balance colour, clarity, cut, and setting in a way that lets the stone feel alive rather than overly polished.
Prioritize Colour First
Colour is the single most important factor when choosing an emerald.
The most desirable stones display a rich, vivid green with strong saturation and even colour throughout. If an emerald looks too dark, it can lose its vibrancy. Too light, and it may lack the depth associated with fine emeralds.
A high-quality emerald should still look lively under different lighting conditions, not flat or dull.
Expect Natural Inclusions
Unlike diamonds, emeralds are not expected to be perfectly clean.
Most natural emeralds contain visible inclusions, often called jardin, because they resemble tiny garden-like patterns inside the stone. These inclusions are part of what makes emeralds unique.
What matters most is whether the inclusions affect durability or distract heavily from the stone's appearance.
Pay Attention to the Cut
The cut influences both the emerald's appearance and its durability.
The classic emerald cut remains popular for a reason. Its rectangular shape and step-cut facets highlight colour while reducing pressure on the stone's naturally included structure.
Other popular cuts include:
-
Oval
-
Pear
-
Cushion
-
Round
Each shape gives the emerald a slightly different personality, from bold and structured to softer and more organic.
Choose a Protective Setting
Emeralds are durable enough for jewellery, but they still require thoughtful settings, especially for rings worn daily.
Protective designs like bezels, halo settings, and secure prongs help shield the stone from accidental impact and reduce long-term wear.
A good setting should protect the emerald without overpowering it. The stone should remain the focal point.
How to Care for Emerald Jewellery
Emerald jewellery requires more care than harder gemstones, but proper maintenance is straightforward.
Clean emeralds using warm water, mild soap, and a soft cloth. Avoid ultrasonic cleaners and steam cleaning, as excessive heat and vibration can damage the stone or affect clarity treatments.
It is also best to remove emerald rings before exercise, heavy lifting, or activities that could expose the stone to sudden impact.
To help preserve emerald jewellery:
-
Store pieces separately to avoid scratches
-
Keep them away from harsh chemicals
-
Avoid prolonged exposure to extreme heat
-
Have settings checked regularly by a jeweller
With proper care, emerald jewellery can last for generations.
