When you’re shopping for loose CZ stones on CubicZirconia.com, know that we use carat-equivalent sizes.  That means that when you buy a 2 carat Cubic Zirconia, we match up the size dimensions for a perfect 2 carat diamond and make sure you get a match in size measured in millimeters.  For example, in Round cut that would be an 8.00 mm CZ stone, or a two-carat round cut diamond equivalent.
