The four-leaf clover is a rare variation of the common three-leaf clover, or white clover. Each leaf is said to represent something special: faith, hope, love, and luck. Finding one is considered a sign of good fortune, as they are estimated to occur in about 1 in 5,000 clovers. In various cultures, the four-leaf clover has been associated with Celtic traditions and Irish folklore. It is often believed that carrying one can bring protection and prosperity. This symbol of luck has made its way into popular culture, appearing in art, literature, and even as a motif in jewelry.
