Boucheron - Quatre Classique Mini 18-Karat Yellow, White And Rose Gold, Pvd And Diamond Necklace - One Size

You'll be able to wear Boucheron's 'Quatre Classique' necklace with other pieces - the cylindrical pendant features 18-karat yellow, white and rose gold bands, so you don't need to worry about the metals not matching. The final ring is made from deep brown PVD, etched with ridges to mimic the cobblestones of the Place Vendôme in Paris. It's finished with a single shimmering diamond.
