Scroll Effect Dress Ring

How do you get 3 into 1? We remodelled our clients three diamond set rings into one wide rail and scroll dress ring. Sat in the centre of this ring would be a very large round diamond that as you would imagine, became the focus point of the design. The width and height were also determined by sheer size of the stone but we wanted to reduce the amount of metal used so we choose to go for a rail/open band with a scroll effect that would seat the remaining stones from her rings.
