May Birthstone: Emerald Meaning, Color & Jewelry
Emerald is the birthstone for May, the green variety of beryl and one of the most treasured colored stones in history. Its color is the whole point, a rich, slightly bluish green that has stood for spring, renewal, and new life since antiquity. Emerald rewards careful handling, since most stones carry natural inclusions as part of their character.

The meaning of May's birthstone
Few gems carry as long a history as emerald. The ancient Egyptians mined it more than four thousand years ago, and Cleopatra was famous for her love of the stone, while later the Romans and the Inca treasured it just as deeply. Its green has always been read as the color of spring and growing things, which made emerald a symbol of rebirth, fertility, and hope, and it was once believed to sharpen foresight and reveal the truth. As the May birthstone, arriving with the height of spring, it carries that sense of renewal and fresh life into a gift.
The color of emerald
Emerald is the green form of beryl, colored by traces of chromium and vanadium, and with emerald color is everything. The finest stones show a vivid, pure green, neither so dark that it loses life nor so pale that it drifts toward ordinary, often with a faint blue cast that gemologists prize. What sets emerald apart from most gems is that nearly every stone carries inclusions, so many that the trade affectionately calls them the jardin, French for garden. These are accepted as the signature of a natural emerald rather than treated as faults, within reason. Because tiny fractures are common, most emeralds are filled with oil or resin to improve clarity, a long standing practice that should always be disclosed. For a full look at how color, clarity, and treatment come together, the guide to evaluating emerald quality walks through each one.
Choosing emerald jewelry
Lead with the green, since color carries an emerald more than anything else; look for a saturated, lively tone you are drawn to. Expect a jardin, and judge inclusions by whether they sit safely inside the stone or reach the surface in a way that threatens durability. The emerald cut, the rectangular step cut that takes its name from the gem, was developed in part to protect the stone's vulnerable corners while showing its color to full effect. Setting matters for protection as well as looks: yellow gold gives a classic, regal warmth, while white metals make the green read cooler and brighter, and a bezel or protected mount suits a ring that will see daily wear. The emerald jewelry at Oath includes pendants, earrings, and bracelets in gold and sterling silver.
Caring for emerald jewelry
Emerald rates 7.5 to 8 for hardness, but its many inclusions make it more brittle than other beryls, so it asks for gentler handling than its hardness alone suggests. Never use an ultrasonic or steam cleaner, since both can strip the oil or resin that fills an emerald's fractures and can even open them further. Clean instead with a soft, damp cloth and a little mild soap, then dry gently. Protect a ring from knocks, take it off for rough work, and have a jeweler re oil a stone that begins to look dry over the years. The fine jewelry care guide covers cleaning and storage for every stone and metal in more detail.
In short
- Emerald is May's birthstone, the green beryl tied to rebirth, spring, and hope.
- Color carries the stone, a vivid slightly bluish green, and natural inclusions known as the jardin are expected rather than faults.
- It is hard but brittle, so skip ultrasonic cleaning, clean gently, and protect a ring from knocks.
