Here is a collection of Roman jewelry that I have tried to recreate. Unfortunately, most of the original pieces went through auction houses (as the shiny jewelry tends to) and they specified that their photos could not be displayed in any public form. Even though this is non-commercial and educational site, displaying the photos would violate copyright law. Some pictures, when clicked, will bring you to the original source.
