A signature of Nikos Koulis’ aesthetic, the Oui collection is defined by clean architectural lines, striking gemstone cuts, and the graphic contrast of black enamel and diamonds. Crafted from 18kt white gold (750/1000) and the brand's iconic black enamel, this ring is accented with dazzling round-cut diamonds in a shared-prong setting. Designed to transcend trends, this piece makes a lasting addition to any fine jewellery collection.
