Cubic zirconia is a man-made material used to imitate diamond and other gemstones, commonly referred to as CZ. Cubic Zirconia has a thermal insulating property while diamond is a very efficient thermal conductor. It is therefore easy to separate diamond from CZ with a simple thermal conductivity test like that found in most diamond testers.
There is an extremely rare natural form of Cubic Zirconia but everything used in jewelry production is the man-made variety.
