Ancient Greeks and Egyptians used to wear diamond wedding rings on their left-hand ring finger. This is because they believed that one of the veins in their left-hand ring finger went directly to the heart. Diamond wedding bands have been popular among women since the late 14th Century. However, men began wearing these bands only a few years ago. During the Second World War, men used to wear wedding rings to remember their wives who were waiting for them. These rings were considered as a symbol of commitment. Nevertheless, a few decades later, men's diamond band ring became popular among civilians too. There are plenty of different types of diamond wedding bands available in the market for men. Platinum and white gold men's diamond wedding bands are the most popular choices out there. However, rose gold men's diamond band ring has also started to make a comeback. The major downfall of white gold men's diamond wedding bands is that they contain nickel. Wearing jewelry pieces made of nickel may result in allergic reactions for some men.
