Engagement Solitaires Is A Solitaire The Traditional Engagement Ring?

Is a solitaire the traditional engagement ring? - engagement solitaires

My friend and I am looking for engagement rings and recently found the ring of my dreams. It is a princess cut, three stone rings with a smooth band. But I have heard that traditionally receives a loner and an engagement ring, and three stones are birthday parties. There are three stone rings wedding bands popular, or should I look for in solitude?
