Does wedding tradition dictate that the wedding band be gold, or can it be another material, such as platinum?
The traditional Jewish wedding band is plain gold, but beyond that, you can choose any type of band you like. Sleek and modern platinum has been hugely popular over the past five years for engagement and wedding rings -- sales are booming, even though gold is the traditional "marriage metal" and currently making a comeback. If you like the look of white metal but can't afford pricey platinum, go for white gold or silver. You can always upgrade later!
