Emerald Cut Engagement Rings
Important Diamond Classifications

Many individuals do not know how different are man-made diamonds and cubic zirconia. Besides, some even imagine that they are something very similar. Despite the fact that they seem to be comparable, these two sorts of stones are different in their own way. It is suggested that you perceive what they are made of so that you can differentiate between cubic zirconia and man-made diamonds (otherwise called synthetic diamonds). Below is a discussion on these two categories of gemstones and their difference that will help you choose the right emerald cut engagement rings.

Cubic Zirconia Composition

Cubic zirconia is a type of zirconium dioxide. It is made artificially and is normally colorless and comparatively flawless. Its optical and physical properties resemble those of diamond. Cubic zirconia is regularly utilized as a diamond replacement.

Man-Made Diamonds Composition

Man-made jewels are made artificially in a lab. They are otherwise called lab-grown diamonds, cultured diamonds, cultivated diamonds, synthetic diamonds, and created diamonds. In opposition to what a few people think, man-made precious stones are not viewed as fake phony since they are made in a synthetic way. These stones are genuine diamonds as they have indistinguishable chemical features and physical attributes like regular diamonds.

Differences Existing between Man-Made Diamonds and Cubic Zirconia

Cubic zirconia and artificial diamonds are clearly different in their physical and chemical features.

Here are probably the most detectable contrasts that may assist you in identifying these stones


Manmade diamonds are essentially tougher than cubic zirconia. This is basically because of the distinctions in hardness between these stones. While synthetic diamonds are evaluated at 10 on the Mohs grade of hardness, cubic zirconia has a rating of 8.5. Consequently, cubic zirconia is a lot simpler to scratch and is commonly less strong than lab-made diamonds.

Facets and Cut

Cubic zirconia is milder than man-made diamonds. When they are cut and polished, these two materials vary in the sharpness of edges of their facets. Synthetics, similar to normal diamonds, have facets with exceptionally sharp edges. Faceted cubic zirconia stones are characterized by edges that are progressively rounded. With time, they become significantly rounder as the material is lost to wear. If you are hoping to purchase genuine diamond jewelry, it is recommended that you purchase from a spot where you can see the real stone before the buy.

Fire (Dispersion)

Another contrast between cubic zirconia and man-made precious stones lies in the degree of dispersion they exhibit. This property is identified with how a stone separates light into a rainbow of spectral hues – an impact also known as”fire.” Cubic zirconia has higher scattering, and consequently, when presented to light, this stone shows flashes that are brighter than those in a synthetic diamond.


Cubic zirconia is a material that is heavier than normal or manufactured diamond. Subsequently, if you gauge a cubic zirconia stone and contrast its weight to that of a man-made diamond of comparable size, the cubic zirconia ought to be much heavier.


Synthetic diamonds have similar properties to natural stones. In spite of the fact that synthetic diamonds are less expensive to deliver, they are still reasonably costly in comparison to cubic zirconia. As a matter of fact, it is frequently the case that a cubic zirconia costs a small fraction of the cost of synthetic diamonds of comparative size, hue, and clarity.

Color and Clarity: More Similar than Different

Cubic zirconia ordinarily is clearer and more lackluster than most regular diamonds because of its synthetic birth. Note that man-made jewels are bound to have shading and clearness that are also very good. The lab-made diamonds can have yellowish hues and in some cases even have normal-looking flaws. The synthesis procedure used to deliver these stones guarantees that imperfections are limited, similar to the case of cubic zirconia. Therefore, the extent of clarity and dryness of a stone ought not to be your essential method for identifying man-made diamonds from cubic zirconia.

Heat and Electric Conductivity: the Best Way to Test

Man-made diamonds and cubic zirconia is different in the manner they conduct heat and electricity power. This makes it simple to reveal their type using a diamond analyzer. This is a gadget that estimates the conductive characteristics of materials.

This is yet another reason why utilizing such a device is the most secure approach to determine whether the stone you have is a diamond or something different. Most diamond testers analyzers will show whether a stone is a diamond. However, note that if it is not a diamond, they will not reveal to you whether it is cubic zirconia.

Bear in mind the above points of difference as you look to purchase jewelry for the special occasion like your engagement. Clear your misconceptions before you purchase the emerald and diamond ring that fits your needs.
