Uneek Cushion Sapphire-Centered Three-Stone Engagement Ring with Trapezoid Diamond SidestonesTraditionally, cushion cut centers are reserved for pieces that are more feminine, but this ring is testament that a little rule breaking here and there can be a good thing; the modernist loving woman will love the angular look of the trapezoid cut diamond sidestones, but will also appreciate how it is softened by the cushion center and the soft edged diamond halo surrounding it; from Uneek's Royal Blue Collection.
