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.
All gemstones can be damaged through wear and tear. Make sure you check for loose stones or damaged prongs periodically. Always take your jewellery off whenever you are doing activities that might cause damage. Remember that household cleaners and chlorine in swimming pools can damage many gems.
Jewellery is best stored individually in a soft pouch or a box with compartments away from sunlight and where harder gemstones can’t scratch softer ones.
