ABSTRACT OF THE DISCLOSURE A diamond-coated article comprises a first, electrically-conductive diamond layer disposed on a substrate and a second, electrically-insulating diamond layer disposed over the electrically-conductive diamond layer. The article may be fabricated by a process including the steps of forming a thin, electrically conductive layer of diamond immediately adjacent to the surface of the substrate of the diamond-coated article, followed by further formation of electrically-insulating diamond material on top of the electrically-conducting layer. A method for indicating wear of the article comprises the steps of passing a current between the tool and the workpiece and detecting a change in the flow of current caused by exposure of the first diamond layer. Another diamond-coated article comprises a first diamond layer having first optical properties disposed on a substrate and a second diamond layer having second optical properties disposed over the first diamond layer. The article may be fabricated by a process including the steps of forming a first layer of diamond having first optical properties immediately adjacent to the surface of the substrate of the diamond- coated article, followed by further formation of a second diamond layer having second optical properties on top of the electrically-conducting layer. A method for indicating wear of the article comprises the steps of directing light at the surface of the article and detecting a change in transmission, reflection, scattering, or other optical property of the diamond wear layers.
