Roberto Coin

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.



Grunos is founded on quality, trust, service and loyalty and has continued to uphold those values today…
