I’ve never seen this type of jewelry so I don’t know what the process is called. I can explain that there is a series of colorful flowers floating in a sea of enamel in a silver tone setting. It is signed “Lacroix” on a silver tone bar. La Croix was always ahead of his time and this cuff is a showstopper. The cuff measures 2” in width and the inside is a shiny metal and will fit the average wrist.
