Three cushion shaped cabochon tourmalines, in green, amber, and rose, are set across an ornate 18K gold band from the Happiness collection. Trefoil diamond clusters accent each corner of the stones, while the band itself is a masterwork of openwork filigree, milgrain detailing, and textured motifs. A ring that celebrates the full spectrum of color in tourmaline with equally abundant goldsmithing artistry.
