Emerald, the birthstone for May, has been beloved for millennia, evoking rebirth and renewal.
Widely regarded as the definition of green, emerald is the perfect color for spring. From the poetic description of Ireland as “the Emerald Isle” to the vibrant green of the famed gemstone itself—the May birthstone emerald has captured hearts and minds through the ages.
Variations of this rich green color suggest soothing, lush gardens. Legend has it that emerald has the power to make its wearer more intelligent and quick-witted, and it was once believed to cure diseases like cholera and malaria. Today, it’s the gemstone given for the 20th and 35th wedding anniversaries.
