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 through different cultures, multi-ethnic influences, and the natural world. Transferring these perspectives into jewels 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 Rockford location, Gruno’s Diamonds is pleased to bring his collection to Gruno’s Diamonds in Madison.
