WINNER Yoko London, Vigneto: Earlier this year, Yoko London chief executive officer Michael Hakimian acquired a range of freshwater pearls unlike anything he had seen in his 30-year career. They were deemed so rare and so spectacular, that Yoko London designed a whole collection around them; celebrating their exceptional size, fine quality and natural lilac hue (dubbed Radiant Orchid because of its similarities with Pantone's Colour of the Year 2014) with contrasting 18ct white gold and sparkling diamonds. The result is the Vigneto collection of statement rings and earrings, plus a strung pearl necklace, designed to showcase the quality of each Yoko London pearl. The ring (pictured), set with 1.64 carats of diamonds, perfectly captures the swirling fluidity of the entire range, with each pearl encased in rippling, floral designs.
