A defining motif of the house, Bvlgari's Parentesi collection is Roman at heart — its design taking inspiration from the interlocking shapes of the cobblestone streets of Rome. First created in 1982, it was built around a deceptively simple idea: three interlocking elements — an hourglass, a bracket, and a connector — that could be combined, scaled, and adapted into an entire range of jewelry without ever losing their internal logic. This signed vintage 18K yellow gold collar necklace is that idea at its most complete. The open bracket links run the full circumference, sitting close to the neck with a presence that is architectural and entirely confident. Presented in its original Bvlgari box.
