An additional characteristic of Zirconia is that it is less durable than Diamond. This stone is more brittle than Diamond but what you have to be aware of mainly is that Zirconia scratches so easily and will start to look worn.
A Cubic Zirconia corresponds to that of a Diamond having a high grad of color. Zirconia is purely colorless and will not have any shades present in the stone. So, if you purchase a Cubic Zirconia, no need to worry about seeing any hints of yellow. A helpful way to tell a CZ from a Diamond is to look at the flashes produced by the stone when light enters it. It shines in all the colors of rainbow and has a brilliance that is a lot more colorful than a real Diamond.
As far as the weight comparison between Zirconia and Diamond, the Zirconia weighs more than Diamond. In conclusion, the two stones of close to actual size, the CZ will be noticeably heavier.
