It is a good idea to choose a diamond that weighs less than 1 carat to keep the ring look subtle. Yet again, if you want to have over a 1ct diamond on the ring band, select small diamonds arranged around the band but choose a setting that fits the gems inside it so that a smooth look can be achieved. This way, you can flaunt the diamond ring without having to be ostentatious.
Another trendy aspect that adds to the style of the ring is colored diamonds, which seem to be making a mark in diamond rings for men market these days. If you have a tungsten or titanium band that looks every bit masculine, choose a black diamond on it for creating a bit of shine, while keeping its look rather edgy.
