Coppolo e Toppo for Valentino tube necklace. This extremely rare couture piece made by the Italian brother and sister designers Coppola e Toppo was commissioned by Valentino. I’ve never seen this exact piece before but their series of tubular and rhinestone designs is some of their most sought after works of art. This Pezzo Forte is in mint condition and measures approximately 24″ long. Although made in the 1960’s, it has a timeless quality and a contemporary haute couture feel. This is an exciting piece to add to your wardrobe or collection. If you love it buy it, I could not find any record of another necklace of this design ever offered for sale.
