This week’s stack features three total showstoppers by one of our favorite jewelry designers, San Francisco-based Rebecca Overmann. A wide band set with five gorgeously graduated salt and pepper diamonds forms the base, showing off Rebecca’s signature softly matte finish 14k gold setting. A double halo dazzler is the centerpiece, featuring a breathtaking 2.28ct oval gray-green center diamond. And our dramatically arching crown is a curved nesting band set with a 0.87ct shield cut champagne diamond, accented with 0.22tcw of round white rose cut diamonds.
