US Patent 7143607 Jewelry article having interchangeable setting and capture module

A jewelry article includes an interchangeable setting, a shank or body, and a capture module. The shank defines a mounting area that holds the setting on the shank except substantially along one axis when the setting is positioned in the mounting area. The capture module couples on the shank. For example, the module can include a slot fitting on a portion of the shank. When the module is coupled on the shank, the module prevents removal of the setting from the mounting area substantially along the one axis. When worn by a wearer, the finger of the wearer, for example, maintains the module coupled to the shank so that the setting is captured on the jewelry article.
