Here you see two rings...the Magnificent Seven is an 18K yellow gold ring with seven diamonds set in platinum bezels. This ring was made to pair well with the "Mom's Diamond and Ruby" ring. Mom's diamond had some chips we could not ignore. We got the diamond recut and it is super sparkly again! Both rings are comfort fit (softly curved inside surface) and flat on the outside. The platinum has some texturization- lines cut into the surface- to keep it visually interesting. Both rings have identical outside diameters- it is a satisfying feeling to line them up. Married metals- opposites really do attract!
