Cut: cubic zirconia gemstones may be cut differently from diamonds. The facet edges can be rounded or "smooth". Color: only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. By comparison, a cubic zirconia is often entirely colorless: equivalent to a perfect "D" on diamond's color grading scale.
Other desirable colors of cubic zirconia can be produced including near colorless, yellow, pink, purple, green, and even multicolored. Thermal conductivity: cubic zirconia is a thermal insulator while diamond is one of the most efficient thermal conductors, with the thermal conductivity exceeding that of most metals. This allows diamond to be distinguished from cubic zirconia with the right instruments. Both are produced in laboratories. And both are crystalline in the non-amorphous morphology of the substance we know as glass.
