Sunlight Journey -- the latest high jewelry collection from Piaget -- is inspired by the colors and diversity of landscapes on Italy's Amalfi Coast. White and yellow diamonds, blue and pink sapphires, red spinels, tourmalines, black and white opal, and emeralds adorn necklaces, bracelets, rings, earrings, and cuffs, playing with colors and light. Here's a look at some of the most spectacular pieces in the collection.
