Emerald
stone-of-the-month-may-emeraldAs the birthstone for May, the emerald, a symbol of rebirth, is believed to grant the owner foresight, good fortune, and youth. Emerald, derived from the word smaragdus, meaning green in Greek, was mined in Egypt as early as 330 B.C. The availability of high-quality emerald is limited; consequently, treatments to improve clarity are performed regularly.
