The Gents will be delighted to hear that the wedding ring selection is nearly as large as the ladies! There are so many more choices out there now for the guys, and hey lads, don't undersell yourselves, this is your chance to wear something for the rest of your life - so don't give your lovely fiancee the entire budget, save some for yourself and pick something that eventhough it may only come out on state occassions, enjoy it when it is worn and the symbolism behind it !
The popular styles for men are the hard wearing tungsten carbide and stainless steel wedding bands. Compared to gold they are less expensive but are a much darker metal than gold and palladium so make sure you and your partner like the colour before choosing one! Palladium is part of the platinum family, hence keeps it whiteness longer than say an equivalent white gold ring. All metals will scratch, there is no way around this - but think of the type of work you do, if you work on a building site, then white gold may not suit you but if you are in an office, a diamond set band would be ideal and dressy day and night - it depends on your choice !
It is important gents, to come in at least once to have your finger measured. It isn't something that can be guessed, you will end up having to change or alter closer or after the wedding so spend a half hour on yourselves and choose your own wedding ring, you will be glad in the long run!
