ABSTRACT:
A process for making diamond and diamond products includes the steps of ianting ions in a diamond substrate to form a damaged layer of non-diamond carbon below the top surface of the substrate, heating the substrate to about 600-1200.degree. C. growing diamond on the top surface of the heated substrate by chemical vapor deposition, and electrochemically etching the damaged layer to separate the grown diamond from the substrate along the damage layer. The diamond product consists of a first diamond layer and a second diamond layer attached to the first layer. The second layer contains damage caused by ions traversing the second layer.
