This is a vintage cuff bracelet made by Originals by Robert in the 1960s. The bracelet is made of gold base metal and features guilloche red and gold enamel. It is an original piece and has a unique art theme. The bracelet is signed by the designer and is in pre-owned condition. His enamel work on this is very fine. This form of enameling is called guilloche which involves engraving the design onto metal and applying layers of enamel. All of this is done by hand and a very intricate process. It is gold plated with a high gloss enameling. It is 2 1/4 at its wides point and overlaps. This is best suited for a size 4.5 to a size 6 wrist so the bracelet will close properly. Best for a small wrist. It is a masterpiece and a rare find. My family kept it in good condition for years.
