Uneek Cushion-Cut Yellow Diamond Halo Engagement Ring with Split Upper ShankA sizeable stone in a minimal setting an ideal design to amplify the impact of a glorious cushion cut, fancy yellow diamond; a simple setting with prongs seem to barely contain this imposing 2. 30 carat stone, but provides the perfect balance with its 54 colorless rounds weighing an additional 0. 33 carats; from Uneek's Natureal Collection.
