The CHIMERA earrings consist of a mix of stones in varying color shades, alternated with gold and silver metal beads and freshwater pearls, all in subtle asymmetry. Atelier Nicol jewelry is entirely made of brass (nickel-free, hypoallergenic), then coated with a layer of gold. The three-micron plating allows each piece to accompany you daily and last over time. The silver-plated jewelry is, on the other hand, covered with a layer of silver ten microns thick.
