Emeralds are widely accepted as the Birthstone for the month of May. Although no one knows the true origination of "birthstones", the idea of birthstones can be linked as far back as Babylon. It is known that the Indians and Babylonians created a link between birth months and corresponding gems.

The birthstone concept has also been liked to Judeo-Christian beliefs. At the command of Moses, 3500 years ago, Aaron built a breast-plate consisting of 12 gems. Theologians of the Jewish and Christian faith believe this breastplate was symbolic of the 12 months of the year and signified the birthstones. Since then, jewelers have often revised the list of birthstones leading to the list that is in use today.

The custom of wearing gems as birthstones, may have originated three centuries ago in Poland. Since then, the custom has become widespread. It is believed that the wearing of your birthstone will bring you good luck.
