I love this Perforated ring from Interior Designer, Kelly Wearstler. It's artful, simple and geometric design makes it appropriate for either a man or a woman. It could be stacked with a simple diamond band, worn with either gold or silver accessories to create an eclectic fashion statement or even worn as a wedding band with an avant-guard splash. The ring is made of solid brass and is available in either a brass or gunmetal hue. Here.
