Cubic zirconia can be evaluated using the same qualities that diamonds and other gemstones are graded by: the Four Cs (color, clarity, cut and carat weight). A CZ is not as durable as a diamond, sapphire or ruby, and that means it is more likely to become scratched over time. Cubic zirconia can be transformed into the same popular cuts and shapes that are used for diamonds and colored gemstones. 2  A white CZ is truly colorless, with none of the inclusions found in an untreated diamond -- think of it as a little too perfect.
