My ring size is 1.5, and I want a marquise diamond for my engagement ring. There does not seem to be too many options for settings, but I like the cover and channel settings thus far. My finger is about 2.5 inches long, so I prefer the width of the setting not to be overpowering. Does anyone know of designs that are classy and elegant? I prefer something clean and simple where the focus is on the marquise diamond. Please help
