The spring auction season of Il Ponte enters its most flourishing phase with Important Jewels, taking place on 28 and 29 May 2026.
A precious selection spanning more than a century of history — from nineteenth-century creations to contemporary design — unfolds in a dialogue between the great French maisons, the excellence of Italian high jewellery craftsmanship, and the stars of cinema, with three pieces once belonging to Gina Lollobrigida.
The international stature of two major French maisons is represented by Cartier with a lapel pin dating to circa 1925 (lot 500, €3,000–5,000), and Boucheron with a demi-parure in rock crystal, presented in its original fitted case (lot 621, €15,000–25,000).
