Abstract: A method of manufacturing a diamond watch crystal wherein the present invention employs multiple techniques to produce the final product. The method of the present invention initiates with a chemical vapor deposition process wherein a high purity graphite is employed as the source substrate. This step further deploys utilization of gases, temperature and an energy source to facilitate formation of a diamond layer on the substrate. The present invention provides alternate energy sources during the chemical vapor deposition such as but not limited to, microwave plasma, direct current plasma, inductively-coupled plasma and hot filament techniques. The method of the present invention further deploys a high pressure high temperature step subsequent the chemical vapor deposition step. These two steps are repeated wherein the initial latter step includes a diamond seed. A final high pressure high temperature step is utilized to remove impurities prior to cutting and polishing.
