The tradition of the birthstone began early in civilization, when various gems were believed to possess magical properties. The color of the stones was first associated with zodiac signs, but later changed to the months of the calendar. This idea was adopted in 1912 by the American National Association of Jewelry, which is known today as Jewelers of America. People still enjoy wearing birthstones because of the folklore and tradition it entails. Some also believe that wearing them provides protection and brings good luck.
