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.
Gold is the most malleable of all metals. It can be drawn into a monoatomic wire, and then stretched about twice before it breaks. A single gram of gold can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet. Gold is a good conductor of heat and electricity.
