Method and System to Produce Large Size Diamonds

Abstract

The invention provides methods and systems for producing large size diamonds. The methods include using carbon containing gases and supplementary gases to form reaction zones that are suitable for diamonds to grow; controlling the temperatures that are suitable for diamonds to grow; and keeping the small size seeds in motion in the reaction zones to form large size diamonds. The method provides controlling the high temperature endurable small size seeds at suitable temperatures for diamonds to grow and keep them in motion in the reaction zones. The invention also provides systems that allow all the surfaces of the high temperature endurable small size seeds continually extend to form diamonds, then to form large size diamonds. The invention provides a large-scale, low cost production of large size diamonds.
