This intriguing brooch by Bulgari is set with six-and-a-half carats of round brilliant-cut diamonds, platinum set on a mount of yellow gold wire work. The dynamic, swirling form with intersecting arcs is designed as a pair of interlocking spirals outlined in diamonds, and joined by harmonizing strands of gold wire. Light and airy, this beautifully designed jewel expresses the electric energy and creative Italian spirit of 1950s and 1960s Rome.
