Is there a way to tell the difference between a real diamond and a cubic zirconia?
assistant
Yes, there is. Real diamonds are composed of carbon atoms arranged in an extremely regular pattern, while cubic zirconia is made up of zirconium and oxygen atoms that have been fused together. The structure of cubic zirconia is not as organized as that of a diamond, so it can be identified by its physical properties such as hardness, refractive index, and density.
