Lab Diamonds

Lab-grown diamonds have history of decades, and scientists have improved their manufacturing methods so that synthetic diamonds look exactly like natural ones. At first, lab-grown diamonds were mainly used for industrial purposes such as cutting tools, but as production techniques matured, they stood out in the jewelry market with low costs and the ability to produce diamonds in a variety of colors.

PECVD (Plasma Enhanced Chemical Vapor Deposition): Gas and nitrogen are heated in the pressure chamber to form a carbon plasma deposited on the carbon substrate at the bottom of the pressure chamber, and gradually accumulated and hardened to form diamond flakes, which are then cut into the shape of gemstones.
