Collier vintage in oro 18K con opale (3.50ct ca.) e diamanti (0.36ctw ca.), anni '60/'70This necklace is made up of two main elements: an 18K yellow gold chain, made with rather thick links, and a central decoration. The latter has a beautiful V shape, and is entirely in 18K white gold: the two arms are very sinuous, with the entire length decorated with diamonds, and with a floral element that connects them to the yellow gold chain; the exact center of the pendant necklace is decorated with a cabochon cut opal of approx. 3. 50 ct,
