Abstract
A method of growing a diamond mass in a liquid growth medium. The liquid growth medium can include a carbon source, a diamond growth catalyst such as a diamond catalyst metal-rare earth element alloy or nanocatalyst, and a dissociated hydrogen of a hydrogen source. The carbon source provides carbon atoms for growing diamond and can include a diamond seed material for diamond growth. The molten liquid phase provides a diamond growth catalyst which allows the carbon to form diamond at the temperature and low pressure conditions discussed. Furthermore, the dissociated hydrogen acts as a concentrator for assembling carbon atoms at a relatively high concentration which mimicks, in some respects, diamond growth under more conventional high pressure processes without the high pressure.
