Auverture presents

Nikos Koulis

Structure and fluidity effortlessly fuse in Greek designer Nikos Koulis’s fine jewellery. His designs marry a stark, Art Deco mood with feminine curves and flourishes. Indeed, Nikos tells The Adventurine that he is “always intrigued by taking a classic pillar from the past and redefining it, in my own terms with my own signature.”
