Cubic Zirconia Versus Diamond
There are a few key features of cubic zirconia which distinguish it from diamond:
Hardness: cubic zirconia has a rating of approximately 8 on Mohs hardness scale vs. a rating of 10 for diamond.
The density of cubic zirconia is about 1.7 times that of diamond.
Cubic zirconia has a refractive index of 2.15-2.18, compared to a diamond’s 2.42.
Dispersion is very high at 0.058-0.066, exceeding a diamond’s 0.044.
Only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. By comparison, a cubic zirconia is often entirely colorless: equivalent to a perfect “D” on a diamonds grading scale.
