These rings are a classic style that Gucci produced and I believe them to be circa 1960's. Each band is a size 6 and is 3 mm wide, they are in very good condition with no enamel missing. The markings inside the rings are worn but inside one of the rings you can see the 750 mark (18K)and the two G's facing one another. The other rings marks are worn and incomplete. These rings weigh 5.2 dwt and are being sold as a set.

Note: These are not marked Gucci but with their Gucci style and the "G" mark, I believe that they are.
