Roberto Coin allows his passion and creativity to take shape through the hands of renowned Italian jewelry artisans . Using their skills, they tell the story of Roberto Coin’s borderless imagination through jewels, that become works of art. Each piece is a journey among different cultures, multi-ethnic influences and the world of nature. Transferring these perspectives into jew-els, gives his collections unmistakeable uniqueness. Each piece bears Roberto coin’s signature; a small ruby cast inside the jewel. Creating over 600 new models each year, Roberto Coin’s collections can be found worldwide. Initially bringing his unique and varied collection to our Rock-ford location, Gruno’s Diamonds is pleased to bring his collection to Gruno’s Diamonds in Madison.
