Cubic Zirconia has a bad reputation for being a cheap imitation of a diamond, but it is a good imitation.  When cut properly from high quality material it is hard or impossible to tell apart from a real diamond, especially when the diamond is flawless and colour D as nearly all cz is flawless and colour D.  Good quality cz's are cut like diamonds and the material does not fade over time, my stones are cut like diamonds and do not fade over time.  CZ has a reputation for scratching easily, this is not true at all, it is 8.5 mohs which makes it one of the hardest materials in the world so it cannot be scratched by normal household objects.
