Are rings Important

So I was listening to a program on the radio and they were debating about the relevance of rings, in a committed relationship, either engagement or marriage, and surprisingly, a lot if people thought rings were an unnecessary accessory. They felt it was useless to wear a ring as a sign of love or commitment, and that most men wore them to please their wives and vice versa, I beg to differ, but I'd like to hear your opinion

What do you think? Are rings important?
