Emerald is the birthstone for the month of May because its color symbolizes the rebirth and renewal that comes with spring.
The folklore of the Emerald is that the gemstone has the powers to help one see into the future, be an eloquent speaker and to defeat spells and enchantments.
The most valuable Emeralds are bluish-green to green and have a medium to medium-dark tone. Since Emeralds typically form in six-sided prisms, they are naturally suited for, and often shaped into, the step cut also known as the Emerald cut.
Emeralds are mostly found in Columbia, Zambia, Brazil, and Zimbabwe.
