How To Distinguish Diamond From Cubic Zircon

Diamond and cubic zircon are exactly same from the appearance. That is the reason why cubic zircon (CZ) quickly becoming more popular as a desirable substitute for diamond. Gemologists can agree that CZ comes closer than any other gem material to matching the characteristics of a diamond. How to distinguish them?

Most people, even trained gemologists, cannot tell the difference between diamond and CZ of wholesale jewelry, with the naked eye. Moreover, to the untrained eye, CZ looks identical to a good quality diamond. However, under closer inspection, CZ appears to have slightly less brilliance (or sparkle) than a diamond, and more fire, or flashes of color.

CZ was originally developed by the Russians, for their space program. They were developed as an alternative to diamonds that were used in the optics of their lasers. CZ has a refractive index, dispersion and hardness so close to a diamond it's uncanny.

So what are some key features that can guide you in telling the difference between diamond and CZ of fashion jewelry? Do keep in mind, though, in order to accurately distinguishing the two gems, gemological equipment such as microscope, or loupe, must be used for testing and verification.

To start, let’s take a look at the hardness factor: Did you know CZ ranges between 8.5 and 9.0 on the Moss? Hardness scale whereas diamond, one of the hardest materials known to man, is rated 10, lying at the top of the hardness scale?

Furthermore, glass (or sand) is rated approximately 5 to 6 on the hardness scale, therefore, dust and dirt will not scratch CZ. Indeed, CZ can scratch glass just like regular diamonds, making it more resistant to chipping.

One great difference between diamond and CZ of cheap wholesale online is weight. CZ is heavyweights in comparison to diamonds; a CZ will weigh approximately 1.75 times more than a diamond of equivalent size. So basically, a piece of CZ the same size as a one-carat diamond weighs about 1.75 carats. Well, is that interesting?

Also, under close inspection with a loupe, the facet shapes of some CZ appear different from diamonds. Both gems disperse light a little differently. Dispersion is just a scientific term for the breaking up of light into its spectral colors. With a dispersive power greater than diamond (0.060 vs. 0.044), the more prismatic fire of CZ of wholesale fashion stores can be seen by even an untrained eye.

There have been many instances to see if jewelers can tell the difference between diamond and cubic zircon, just by examining the gems with the naked eye. Over and over again, it was inconclusive; jewelers could not tell the difference just by looking at the gems. So you can now understand why the difference between diamond and cubic zircon rests in the price, and in the mind?
