![]() ![]() It can be given the grade ‘D’ which is the best quality diamond on the diamonds color grading scale.ĭispersion of Cubic Zirconia is higher than diamond making the prismatic fire more intense in it. Cubic Zirconia on the other hand being a synthesized product, can be made absolutely colorless. The really colorless diamonds are the ones which are free of any flaws and usually rare. The color depends on the concentration of nitrogen or other such subsitutes in the diamond. Cubic Zirconia are thermal insulators.ĭiamonds are generally found with a yellow or brown tinge in them, this is due to the nitrogen found in them. On the Mohs’ scale it is 8.5.ĭiamonds are electric insulators and excellent thermal conductors. Cubic zirconia are also relatively hard as compared to other gemstones though its hardness cannot measure anywhere close to diamonds. ![]() Industrial use of diamonds has historically also been associated with their hardness, it can be used to polish, cut, or wear away any material, including other diamonds. This quality is useful in its use as jewelry. ![]() ![]() They are good abrasives and can be scratched only by other diamonds. Shop for diamond jewelry Properties Hardnessĭiamond is the hardest natural material known to man, it measures upto a perfect 10 on the Mohs’ hardness scale. In CZ, the shape of the facet is sometimes different from that of a diamond Production of cubic zirconia is virtually flawlessĭiamonds definitely have some kind of flaw The specific gravity of CZ is between 5.6 to 6 and is relatively 1.7 times more than that of a diamond of the same sizeĠ.044 (lower than cubic zirconium and moissante)ĭiamonds are among the most efficient thermal conductors 8.5 on Mohs hardness scaleĮxtremely hard (10 on Mohs scale). Relatively hard, though nowhere near diamond but harder than most natural gemstones found. Jewelry industrial purposes – high-pressure experiments, cutting tools. Mainly as a gemstone, as it bears high similarity to diamond Since CZ are synthetic, they can be made absolutely colorlessĭiamonds usually have a yellow or brown tinge, the truly colorless diamonds are very rare.Ĭubic zirconia (or CZ), the cubic crystalline form of zirconium dioxide (ZrO2), is a mineral that is widely synthesized for use as a diamond simulantĭiamond is a natural mineral, an allotrope of carbon. ![]()
