Halo Shape
Diamond shape is important but so is the shape of the actual halo! In general, the halo shape usually enhances the natural shape of the diamond but in some cases can be used to create a contrasting style for a dramatic effect.
For example, these two contemporary rings use quatrefoil shaped settings to create an eye-catching look for these antique and vintage diamonds. Both rings feature central round cut diamonds juxtaposing to their square edged settings.
