I'd like to know the difference between a synthetic and natural diamond.

A synthetic diamond is made by man, while a natural diamond is found in nature. Synthetic diamonds are created through a process called chemical vapor deposition (CVD), which involves a high-pressure reactor and a mixture of gases that are heated to extremely high temperatures. The resulting material is then cooled and shaped into a gemstone. Natural diamonds on the other hand, are formed when carbon atoms bond together under intense heat and pressure. This process occurs deep within the Earth's mantle and is not replicable in a lab.
