Lot of 30 stones 4mm Round cut white Cubic Zirconia (CZ). AAAAA grade - highest quality stones
Most gemologists measure cubic zirconia in millimeters rather than carat weight. For example, a 6.5 mm CZ is equal to one carat diamond. A CZ of this size would weigh 1.75 carats. Cubic Zirconia crystals are perfect in structure and have no feathers or inclusions. Imperfect crystal formations are simply discarded. CZ is cut using the same proportions and intensively precise faceting as the finest diamond.
