A CZ described as a cubic zirconia in a jewelry ad isn't an imitation. In contrast, a CZ represented as a diamond "lookalike" is an imitation. Many vendors frequently sell imitation gemstones, typically for far less than the gems they imitate would cost. The reason it’s popular is that, to the untrained eye, they look identical to diamonds. They have almost the same crystal formation and omits and they also have a similar sparkle when help up to the light. What’s impressive about CZ is that it has an impressive 8.5-9 Mohs on the scale of hardness, diamonds being a 10. In other words, a 1 carat Round Cut Cubic Zirconia diamond equivalent is 6.5 mm. When you’re shopping for jewelry on CubicZirconia.com, know that we use carat-equivalent sizes. That means that when you buy a 2 carat Cubic Zirconia pendant, we match up the size dimensions for a perfect 2 carat diamond and make sure you get a match in size Price as a Sign of Authenticity. Rhinestones are much cheaper than real diamonds of similar size, color, and clarity. Although the low price may indicate that you are not dealing with a genuine diamond, some sellers may try to sell you a rhinestone pretty expensively. Use price as a clue only in conjunction with other tests. Here, two jewelry experts explain the differences between lab-grown diamonds and cubic zirconia, according to their price, durability, clarity, quality grade, and color. Cubic zirconia ranks between 8.0 and 8.5 on the Mohs scale, whereas diamonds rate as tens, meaning they're among the world's hardest substances. While cubic zirconia is a comparatively hard stone, it lacks the resilience and durability of diamonds. Prone to chipping, scratches, and other forms of external damage, you must wear it with care. Furthermore, diamonds typically weigh more than zirconia, so a carat is not a direct comparison. That being said, a typical diamond contains around 12,000 carbon atoms per carat, while zirconia contains around 4,000 oxygen and other atoms per carat. So, when it comes to the number of carbon atoms, diamonds definitely have the advantage. As expected, the diamond sparkles the least and exhibits more conservative fire. The moissanite and cz have more sparkle and fire, however as compared to the cz, the moissanite has “tiny internal sparkles” a bit like opal, which in my opinion, makes it the prettier of the stones. 18. This is actually really helpful. Thx for posting this. First we’ll note well that diamonds are harder than cubic zirconias, boasting a perfect 10 on the Mohs scale while cubic zirconias come in at 8.0 to 8.5. Note also that CZ stones are more easily scratched and damaged, and that they gets cloudy and need more frequent cleaning in order to maintain their brilliance. l7vWHU.
