Another way to tell the difference between lab created diamonds and cubic zirconia is by inspecting the clarity. Cubic zirconia is often less clear than diamonds, so if you see any inclusions or blemishes, it is most likely cubic zirconia. 3. Consider the price. Generally speaking, diamonds are more expensive than cubic zirconia.
When compared with cubic zirconia or CZ (perhaps the world's most popular diamond simulant), the differences are obvious. CZ is an inexpensive simulated diamond look-alike, inferior in almost every gemological property to Moissanite. CZ is mass produced under a myriad of trade names and promoted with various brand names.
On the 10-point Mohs Hardness Scale — the industry-standard test used to grade a gemstone’s hardness or durability — cubic zirconia ranks 8 to 8.5, which means it can be scratched and become foggy over time. It also needs to be cleaned more often than a lab grown diamond. Lab grown diamonds, by comparison, score a perfect 10 on the Mohs
Appearance. Simulated diamonds and cubic zirconia are both visually similar to real diamonds, but there are a few key differences in appearance. Simulated diamonds have a more vibrant sparkle and shine than cubic zirconia, and are often more colorless. On the other hand, cubic zirconia can have a slightly yellowish hue and is more susceptible
The prices difference between cubic zirconia and diamonds is pretty significant, but most people can't tell diamonds and cubic zirconia apart. eidetic November 28, 2012 . @anon278338 - You may have seen cubic zirconia stones before, and just not known what you were looking at.
Anyone who says they can tell the difference with the naked eye (i.e. looking unaided, with no special tools or props) between a perfect mined diamond and the top-quality 5A Cubic Zirconia such as that we make and use in our jewelry is: lying only giving anecdotal evidence based on a flawed experiment set-up comparing diamonds to poor-quality CZ manufactured by companies trying to save money
