Cusi is a historic Italian jewellery house founded in Milan in 1886 by Annibale Cusi, a skilled goldsmith who began his career as an apprentice before establishing his own atelier at age 23. Over five generations, the family business expanded its presence—relocating to a Palazzo in Via Clerici in 1922 and later opening boutiques in Milan’s Montenapoleone and Portofino—continuing to produce bespoke gold, platinum, pearl, and gemstone jewellery.
