While these distinguishing factors mostly are invisible to the untrained eye, keep these concepts in mind when making a decision between cz and diamonds. It’s nearly impossible to distinguish cz and diamonds based on looks alone. We naturally think that cubic zirconia makes a fabulous choice for a special or everyday jewelry pieces. But we want shoppers to be as informed as possible when making these important decisions about gemstones.

This article also has other interesting information about the production of CZ. For example, did you know cubic zirconia was invented in 1930?

Here’s an excerpt:

* CZ is 1.6 times denser and therefore heavier than diamond with a higher specific gravity, 5.6 to 6.0.
* Harder than most natural gems and nearly as hard as diamond’s 10, cz registers 8 on the Mohs scale.
* With a refractive index of 2.17, cz is nearly as refractive as diamond which has an index of 2.42.
* Both cz and diamond exhibit subadamantine luster.
* CZ has an exceptionally high dispersion, 0.060, compared to diamond at 0.044, producing greater prismatic fire.
* Completely colorless AAAAA cubic zirconia, comparable to a perfect D on the diamond color grading scale, can be created in the lab whereas most diamonds contain yellow or brown flaws.
