Some women never want to lose sight of an engagement ring. They would like it to wear close to their hearts, and the best place will probably be the fingers. However, when you get married on a wedding day, you either have to put away your engagement ring, or else make sure that you buy a wedding band, which will probably go down well with an engagement ring.
Women are too concerned with matching wedding bands. You can always wear a wedding band with the same diamond cut, as it is on your engagement ring, so that it goes well when you wear a wedding band over your engagement ring. Or else, you can put a contrasting wedding band, on your finger, to produce a unique look, which cannot be missed.
While men can either choose band that matches his women, or he can also put a wedding band with varying thickness.
