There are a few key features of Cubic Zirconia which distinguish it from Diamond:
Hardness. This causes sharp edges to facets in cut crystals to dull and 'round off' in CZ, while with Diamond the edges remain sharp.
Cut: Cubic Zirconia gemstones may be cut differently from Diamonds. The facet edges can be rounded or "smooth".
Colour: A Cubic Zirconia is often entirely colourless: equivalent to a perfect "D" on Diamond's colour grading scale.
Thermal conductivity: Cubic Zirconia is a thermal insulator whereas Diamond is the most powerful thermal conductor. This is the way most Diamond testers work; by testing thermal conductivity.
