Actually, there is no real etiquette on how to wear a promise ring. It can be worn on any finger, as it is totally up to the person who wears it.

Sometimes promise rings are not even worn on any finger at all. They stay safely in their beautiful little gift box. As it is all about the meaning of the given Promise Ring and nothing else.

There are many reasons why people give promise rings and that changes the ‘rules’ a bit too. Usually it’s a sign of close friendship, a symbol of chastity, expressing their loyalty, promise monogamy to each other, or even a promise to oneself to stay clean and sober.

That being said, if there is any romance involved, most people usually wear their promise ring on the ring finger of the left hand.
