An oval green sapphire, set east-west, sits above a cushion-cut white diamond in a build that pairs 18K yellow gold with titanium — gold prongs cradle the sapphire, titanium holds the diamond below. At 4.28 total carats, the sapphires shift between teal and forest green depending on the light, GIA certified, paired with .64 total carats of D-G color, VVS clarity diamonds. The two-stone stack reads as considered contrast rather than simple pairing.
