If you are in the market for a diamond ring, make sure you buy from a reliable seller that offers GIA or AGS grading reports. The main difference when it comes to color is that CZ stones tend to take on more saturated colors and deeper hues. Likewise, cubic zirconia stones are also available in various colors ranging from pale yellow to brilliant reds. Some colors like blue and red are extremely rare in nature and they command very sky-high prices. The differences in their fluorescence characteristics are attributed to the chemical compositions they have.Ĭolor – Fancy colored diamonds can come in a whole spectrum of colors and hues. On the other hand, about 30% of natural diamonds fluoresce in a blue hue when exposed to long wave UV (365nm). In nature, a flawless diamond is extremely rare due to the violent formation process they undergo.įluorescence – Cubic zirconia reacts to short wave UV (254nm) and usually glows in a yellowish color hue. Lower quality CZ can also turn cloudy over time because of its less stable chemical bonds and its tendency to absorb oils.Ĭlarity/Inclusions – Unlike diamonds which are formed in nature, cubic zirconia simulants are created in the lab and they are always flawless. If you are careless with your cz jewelry or accidentally run it across something rough, the stone can quickly lose its luster and become worn out. In fact, diamonds are many times harder than CZ because the Mohs scale behaves like an exponential scale.ĭue to their lower hardness, cubic zirconia is prone to scratching.

Hardness – Diamonds are the hardest substance on Earth and they are ranked as a 10 on the Mohs hardness scale. Material properties of diamond vs cubic zirconia. What is the Difference Between Cubic Zirconia and Diamond? Also, it is frequently misrepresented as a real diamond on unregulated platforms like eBay or Craigslist and poses a problem to unsuspecting consumers. It is important to highlight that cubic zirconia mimics a diamond and is sometimes referred to as a fake, imitation or faux diamond. ![]() Due to its close visual resemblance to real diamonds and extremely low cost, CZ is the most popular diamond simulant in the market. What is Cubic Zirconia And What is It Made of?Ĭubic zirconia is a synthetic material that is primarily made of zirconium dioxide (ZrO2) and can be mass-produced at very low prices.
