1. A method of growing diamond, comprising:

  • a) growing at least one diamond mass from a diamond seed material in a liquid growth medium of a carbon source, a diamond growth catalyst, and a dissociated hydrogen of a hydrogen source, said growing occurring within a temperature profile for a time sufficient to allow three dimensional growth of the diamond mass from the carbon source, said liquid growth medium including a molten liquid phase which is a continuous phase having the hydrogen source dispersed therein under a low pressure; and

    b) removing the diamond mass either from the molten liquid phase or from a solidified mass formed from cooling the molten liquid phase.
