We have narrowed down our custom engagement ring to a 1.5 RB (color F, SI 1, ideal cut) with a small cushion halo but would like to add side stones as we feel my finger(size 5 3/4) looks best with three stones-we have narrowed it down to half moons or brilliant shields. Our jeweler brought in the shapes to help us compare-just for shape not size. I want something unique and timeless. What's your choice-looking at the shape? Any suggestions on size of side stones?
