What is the purpose of a wedding ring? Why do we wear it on the left hand on the 4th finger, also known as the ring finger?
“In some countries, the wedding ring is worn on the left hand. This choice of finger relates to traditions purportedly dating to classical times, from an early usage reportedly referring to the fourth finger of the left hand as containing the vena amoris or “vein of love”[5]. At least in part due to this tradition, it became the norm to wear the wedding ring on this finger. By wearing rings on the fourth finger of their left hands, a married couple symbolically declares their eternal love for each other. This has now become a matter of tradition and etiquette in these countries. However, the most widely accepted explanation is that because the majority of people are right-handed, wearing the ring on the left hand makes it less likely to be damaged or lost during everyday activities.” - Wikipedia
