As MY FAUX DIAMOND offers both stones in our settings, this question comes up often. The main thing that they have in common is the fact that they are both man made stones, made to look like genuine diamonds, but at a much cheaper price. There is a HUGE difference between the two stones. Your choice in stone is usually based upon your personal preference, your budget as well as the durability of the stone, and the longevity of the stone’s value. Cubic Zirconia is actually cheaper for a reason, and that reason is mainly that it is not a stone, it is cheap to create and is NOT as durable as moissanite. However, for those who are budget, conscious plan on using their faux ring sparingly, or plan to add genuine stones later, a CZ is a perfect choice for you today. 5A rated Cubic Zirconia has the same brilliance as many diamonds do…and can be confused by many except for a professional jeweler! Moissanite is silicon carbide, a compound with chemical formula SiC. On the other hand, cubic zirconia is zirconium dioxide, ZrO2. Moissanite is composed out of silicon and carbon, whereas CZ in its crystal lattice contains zirconium and oxygen.
Diamond, as you probably know, is pure carbon. If you compare both of them to diamond, moissanite comes much closer. In fact, moissanite can be understood as being obtained by replacing some of the carbon atoms in the crystal structure of diamond with silicon. Even the local bonding is very much preserved, because silicon has the same valence as carbon and can be accommodated in the same environment. Cubic zirconia is much more different, as it contains zirconium, which is a relatively heavy element with totally different properties. This is why CZ has a higher specific gravity — around 6 — which is almost twice as much as moissanite’s specific gravity of 3.2.The crystal structure of Moissanite is hexagonal, with stacking order ABAC for tetrahedral structures. The structure of CZ (cubic zirconia) is obviously cubic. This as a consequence has the fact that moissanite is not isometric, and is doubly refractive, unlike cubic zirconia or diamond. The double refractivity means that each light ray entering a double refractive crystal or gemstone is decomposed into two rays, unless the crystals are observed from a special direction called optical axes where there is no such effect.
Moissanite is often cut in such a way that the table facet is perpendicular to its optical axis, so if you look at it from the top facet of the stone you won’t see this doubling effect. On the other hand, it can be argued that the very same doubling effect contributes to the increased beauty of moissanite. i.e., it leads to high brilliance (refractive index) and fire (dispersion). When it comes to durability, the durability of a gemstone is determined largely by its hardness. But, other factors can also come into play, such as internal strains in the structure, so be careful. Even though all three stones, moissanite, diamonds, and cubic zirconia, are relatively hard, that does not mean they are unbreakable.
The hardest and most durable is diamond with the maximum possible hardness of 10 on the corresponding scale. Moissanite is dangerously close with 9.2, and the least hard of them is CZ with 8-8.5. Another property worth examining is the toughness. It is the resistance to breaking. Cubic Zirconia has a very poor toughness when compared to Moissanite: 2.4 versus 7.6. Moissanite is almost three times tougher, i.e., three times more resistant to breaking and chipping.

From Charles & Colvard:
Asscher cuts were first developed in 1902 by Joseph Asscher, and became most popular during the Art-Deco movement following World War I. This historical 58-facet design mimics the emerald cut, but offers increased sparkle with its unique octagonal shape.
New moissanite Asscher cuts feature 65 facets to accompany this gems’ double refractive crystalline structure, offering more than twice the brilliance and fire of diamonds.
If you are interested in an Asscher cut gem, keep in mind you will want the highest clarity available since an Asscher cut has a large table and is step-cut. This type of cut creates a hypnotic mirrored pattern to showcase the clarity of the stone.
Forever One™ moissanite presents an ideal gem choice to enjoy the look of the Asscher cut, offering excellent clarity – each stone visually flawless to the naked eye.
Asscher cuts symbolize a history of wealth and royalty, from the famous Krupp Diamond worn by Elizabeth Taylor, to the Cullinan Diamond created for the Crown Jewels.
Modern Hollywood stars like Jessica Alba and Gwyneth Paltrow have brought the Asscher cut back into the spotlight in recent years, donning the look for their engagement rings.
Asscher cut moissanite makes its debut just in time for jewelry designers to stay on top of the latest styles, as Art Deco inspiration comes back in today’s top fashion and jewelry trends.
What is the difference between Moissanite and Cubic Zirconia?
This question we hear often. It is true that both moissanite and cubic zirconia are imitation diamonds which are man made. Other than this, the difference between these stones far outweighs their similarities.
First, we should discuss the difference in the make-up or the composition of each stone. Moissanite is silicon carbide, a compound with chemical formula SiC. On the other hand, cubic zirconia is zirconium dioxide, ZrO2. Moissanite is composed out of silicon and carbon, whereas CZ in its crystal lattice contains zirconium and oxygen. Diamond is pure carbon. If you compare both of them to diamond, moissanite comes much closer.
Which stone is brighter or has more fire and ice? Due to the structure of a moissanite stone it is naturally doubly refractive, which increases the amount of light dispersion from the stone, making it a brighter stone then both the diamond and a cubic zirconia.
The color of the stones is significantly different. Cubic zirconia is a perfect, flawless and pure white stone. This is another clear way to distinguish the difference between CZ and moissanite. Due to the complicated process of production, moissanite stones are neither perfectly white and transparent, nor flawless. They often possess slight greenish or even yellowish hues, along with some imperfections in the structure. For this very reason, moissanite stones are that much closer to a genuine diamond vs. a cubic zirconia.
What is the difference in the stoneâ€™s durability or hardness? Even though all three stones, moissanite, diamonds, and cubic zirconia, are relatively hard, that does not mean they are unbreakable. The hardest and most durable is of course the diamond with the maximum possible hardness of 10 on the corresponding scale. Moissanite is dangerously close with 9.2, and the least hard of them is CZ with 8-8.5.
Finally, there is a significant difference in the cost between these stones. As you know, cubic zirconia costs significantly less than both moissanite and diamonds. If you are looking for beautiful jewelry but want to stay in budget both the CZ and a moissanite may be a better option over a diamond. The 5A rated cubic zirconia (highest quality) costs approximately $100 per carat. A moissanite stone is approximately 10% of the cost of an equivalent diamond of the same carat weight. Moissanite stones have maintained their value over the past 20 years and would most likely make a better investment over a cubic zirconia.
