Abstract
A method of synthesizing single diamond crystals using a carbon source containing at least 99.9 atomic % carbon-12. This is accomplished by graphitizing carbon-12 to form a highly crystalline material which can be used as a carbon source in an ultra high pressure creating apparatus to produce single diamond crystals by means of a temperature difference process.
