Synthetic Polished CVD Diamond refers to a diamond that has been created using chemical vapor deposition (CVD) technology and has been polished to a high degree of clarity and brilliance. These are grown in a lab environment by depositing carbon atoms onto a diamond seed using a plasma process. This can be produced in a wide range of colors, including yellow, pink, blue, and green, which can add a unique and personalized touch to a piece of jewelry. Synthetic Polished CVD Diamond has several advantages over natural diamond and more environmentally friendly as they are grown in a lab rather than mined from the earth.
