Founded in 2011, Alessio Boschi's eponymous luxury jewellery brand uses black opals in startling high jewellery creations of ambitious scale and transformative ingenuity. His Plumes necklace takes the peacock tail as its inspiration and uses 15 standout black opals as the centrepieces of cascading and movable feathers. The high jewellery necklace won the Harper's Bazaar Jewelry China magazine Excellence of Design Award, and also featured as a finalist at the Couture Design Awards 2014 in Las Vegas.
