NIKOS KOULIS Oui 18-karat white gold, emerald, diamond and enamel necklace

Nikos Koulis' necklace is part of the brand's signature 'Oui' collection, which is inspired by the glamour of Art Deco. Crafted in Athens from 18-karat white gold, it's strung with a black enamel pendant centered by a glowing baguette-cut emerald and diamonds. The delicate chain can be worn at two different lengths, so it'll always complement your neckline.
