What is a Lab Grown Diamond?

A lab grown diamond is one that has been manufactured in a controlled laboratory environment. Using the popular methods of Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT), scientists can now create diamonds that optically look like earth-mined diamonds, contain the same chemical and physical attributes and even receive certification through the Gemological Institute of America (GIA) and International Gemological Institute (IGI).
