A Promise Ring has many different meanings. Sometimes it is the first official token of your love when you promise to stay monogamous for instance. Or it can be a promise of trust and companionship.

Of course, a Promise Ring still often symbolizes a promise of future marriage. Then it becomes a kind of pre-engagement ring as you will.

An engagement ring has only one meaning. As it is a romantic, symbolic way to propose marriage to your loved one.

And if your partner agrees to marry you, the ring will go on the ring finger of the left hand and that will symbolize the fact that you are now engaged to be married.

Then it is time to tell all your friends and family the happy news that you want to marry him or her in the nearby future.
