What is Cubic Zirconia?

Cubic zirconia (CZ) is the manmade mineral made of zirconium dioxide (ZrO2), the material hardiness is quite considerable and can be made in a variety of different colors despite of its natural transparency. CZ stones also have been found in nature in small amounts, but the vast majority used in jewelry smithing are from laboratories. Due to increased demand, commercial production of CZ began in the 1970s & still maintains to be trending nowadays.

Thanks to the invention of cubic zirconia manufacture, customers now can purchase colored gemstone jewelries with affordable prices.

Is Cubic Zirconia a diamond?

Since all CZs are lab-created, they should not be considered as diamonds under any scenario by both experts and non-experts. For many reasons – from chemical properties to brilliance and color – the two stones are entirely different.

CZ stones are not considered synthetic diamonds because the chemical ingredients are not identical with any from the natural ones.

Differences between cubic zirconias & real diamonds


Some people might think that diamonds should have a clearer surface than CZs because they are more expensive & authentic; however, a ‘white’ diamond can still have a yellow, gray or brown tint. In addition, nearly all natural diamonds have tiny dark specks – called inclusions – inside. Only trained eyes from expert jewelry makers or jewelry inspector can identify the differences through a magnifier, or microscope if in laboratories.

Another effective way to tell the differences between CZs and diamonds is by putting them under natural light. Natural diamonds will give off more white light (brilliance) while CZs only give off a noticeable rainbow of colored light (excessive light dispersion). The excess light dispersion is a key sign that the stone is not a diamond.

Light dispersion plays an important role in determining real diamonds & CZ stones.


A chunk of cubic zirconia stones is heavier than a diamond of the same size, but not as hard. CZ stone is scored 8.5 on the Mohs scale, while diamond is rated at 10 (which is considered as the hardest substance) & synthetic Moissanite stone is 91/4 right behind. Nevertheless, it is true that CZ stones can mimic real diamonds pretty well & more reasonable to purchase.


As mentioned above, one thing that customers can tell between the types is their prices. Although diamonds can be appraised by multiple factors, one thing that can be assured is that diamonds always have much higher value than CZs with the same size.
