A birthstone is a gemstone that is traditionally associated with each month of the year. These stones are believed to bring good luck, protection, and various benefits to individuals born in that month. For example, January is represented by garnet, while December is associated with turquoise. The practice of using birthstones dates back to ancient times, with roots in the Bible and the Jewish priesthood. Each stone is thought to have unique properties and meanings, making them popular choices for jewelry, especially in rings and necklaces. Many people wear their birthstone as a personal symbol or gift.
