Placing a wedding ring on the fourth finger of the left hand is a tradition widely practiced in Western cultures. This custom originates from an ancient Roman belief that a vein—called the "vena amoris," or vein of love—ran directly from this finger to the heart, symbolizing deep connection and eternal love.

Interestingly, this tradition is not universal. Some cultures, such as those in Russia, Greece, and many Eastern European countries, traditionally wear the wedding ring on the right hand's fourth finger. Additionally, in some regions around the world, rings are worn on completely different fingers or even toes during special ceremonies.

While modern anatomy disproves the existence of a special "vein of love," the romantic symbolism remains strong, leading millions of couples today to continue this heartfelt gesture.
