Cubic zirconia is the transparent, crystallised form of a naturally occurring mineral called zirconium dioxide (ZrO 2 ). Due to its popularity with buyers, cubic zirconia is in high demand so much of the cubic zirconia used in the jewellery we buy is engineered in a laboratory. Cubic zirconia is favoured for its remarkable closeness to a diamond. While the CubicZirconia.com CZ stone looks like a diamond and possesses many diamond-like qualities— to the degree that even jewelers with decades of experience cannot visually tell the difference between a high-quality CZ and a perfect diamond by simply comparing the two side by side with the naked eye alone— Cubic Zirconia is NOT a diamond. High-quality Cubic Zirconia vs Diamond is harder to tell the difference than most people realize! Did you know that the untrained and naked eye cannot distinguish the difference between an expensive, ideal cut natural mined diamond stone and the highest-quality flawless 5A Cubic Zirconia stone such as those made, sold and used in jewelry by CubicZirconia.com? The main difference between Cubic Zirconia and actual Diamond is the weight, hardness, and the pricing. CZ weighs more than a diamond of the same size, but is a lot less hard. CZ is usually referred to as "fake" or "faux", as it is not the real thing; but CZ is a lot more affordable than diamond. Diamond refract white light. Cubic zirconia has a lower refractive index than diamonds, 2.22 versus 2.42, and reflects more colored light. Moissanite, however, has a higher refractive index (2.65 – 2.69). Because moissanite has a high refractive index, it reflects vivid rainbow colors. There is a difference in hardness. Cubic Zirconia: Durability And Density. While diamonds score a perfect 10 on the Mohs scale of hardness, cubic zirconia, on the other hand, ranks at 8.5. Since it’s a synthetic material, cubic zirconia does offer some durability. It can be set and worn in jewelry – but won’t have the longevity of a diamond, of course. Available on the jewelry market since 1976, CZ is created from zirconium dioxide, making it heavier than a natural diamond. The added weight makes it more difficult for light to pass through the stone easily, giving the CZ a lower refractive index (and therefore less brilliance) than the natural diamond. While the affordable price of the CZ is 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. .
