Round Brilliant-Cut Cubic Zirconia.

Cubic zirconia is a man-made material used to imitate diamond and other gemstones. Commonly referred to as CZ. CZ has a thermal insulating property and diamond is a very efficient thermal conductor, therefore it is 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.
