Abstract : A method for synthesizing diamond which comprises flowing together a gaseous carbon source and a gaseous hydrogen source to form an at least partially turbulent mixture. The at least partially turbulent mixture is excited to form an at least partially turbulent reactive species which is reacted to form a deposition species. A substrate is disposed in the deposition species while maintaining the substrate at a temperature for the deposition of diamond, thereby inducing deposition of diamond on the substrate.
