Diamonds vs. Cubic Zirconia - Are They Really That Visually Different?

By Jessica Wozniak


Since new technology exists today, it's burdensome to differentiate between cubic zirconia and a real diamond. As a result of this truth, that it's hard to tell the difference, naturally it will become popular (especially since it's much cheaper to create) throughout the world. If you discuss this with a certified gemologist, or a seasoned jeweler, they would tell you the same - cubic zirconia is the best alternative to a real mined diamond.

If you were to look at CZ engagement rings, unless you had a trained eye, it would be very difficult for you to tell the difference between a genuine diamond and a CZ alternative. Even some of the well-trained gemologists have great difficulty telling the difference with the naked eye. Under closer inspection a person will find that the CZ will have slightly less color, flashes, sparkle, and brilliance than a real diamond provides. With that being said, slightly less means you would only be able to tell the difference if you had a diamond for variance.

The invention of cubic zirconia was by Russian scientists to help with their lunar program. As there was a need for a replacement in their optical devices, cubic zirconia was created to replace mined diamonds. But the only way it would satisfy the needs of the program was if it matched the infraction index, dispersion, and hardness of a real diamond's characteristics. As a result of their research for a solution, it was found cubic zirconia was just as effective and an efficient solution needed for the optical devices. Shortly thereafter they made the permanent switch in the program.

With this in mind, the CZ can be used in basically any setting a diamond is placed in. This makes it very valuable in the fact that many pieces of jewelry can use the CZ as a diamond replacement. Now, you can tell the difference between a CZ and a diamond provided you have the right equipment for the job. If you are trying to accurately distinguish the difference between the two gems, you will have to use gemologist equipment such as a loupe or a microscope to get an exact verification.

There are a few things you'll need to know about diamonds, as well as CZ, in order to effectively gather the information needed to be able to tell the difference. Some of these features are hardness, weight, impurities or defects, color, and light disbursement to name a few. All of these areas are key factors in determining whether or not a CZ is not a diamond and vice versa. Because of the way cubic zirconia is made, it will not be as hard, it will not weigh as much, they will have less impurities than diamonds do, the colors are not as brilliant, and it disperses light in a slightly different way.

Making sure you are educated in all the differences can help you in the final stages of your jewelry purchase. Cubic zirconia has made significant advances recently and even the most picky people will be impressed by what they actually look like, and that you can't even tell the difference with a naked eye.
