Crack open those books and get your graphing calculator ready, it’s time for a geometry lesson! Mixed cut diamonds – brilliant circles and trapezoidal baguettes - combine in a sleek vintage platinum setting at our stack’s base. We add volume with Rebecca Overmann’s 14k gold half eternity band, with its pavé diamonds like plotted points on a graph, mapping a cosine’s curve. Pop quiz: which ring adds up a multitude of dazzling diamond shapes - pairs of equilateral triangles with an elegant oval center and tapering rounds? This Rebecca Overmann stunner in matte finish 14k white gold. We top off our stack with Nan Collymore’s three gray diamond circles for extra credit.
