The trend in lab grown diamonds (LGD) is the use of MPCVD (microwave plasma CVD) equipment, which grows diamonds artificially by volumizing carbon (C) on a substrate. It is said to be currently capable of producing 20-carat diamonds. when CH4 and H2 are mixed and excited by microwaves, a glow discharge occurs in a vacuum vessel. Molecules of the reactant gases are ionized and a plasma is generated.
In its CVD process, HORIBA's high-quality gas flow control technology, pressure monitoring　product and pressure control solution are used. HORIBA solutions ensure consistent quality diamond growth.
