Top-quality moissanite can be close boring and liberated from noticeable considerations. There are two advantageous characteristics of dismal natural gemstones.

Moissanite is twofold refractive. The light which enters the stone is parted into two as it refracts outwards, making splendor and more noteworthy 'fire' than a jewel. On the Mohs size of hardness, moissanite allots at 9.5 of 10. Moissanite is entirely sturdy and reasonable for ordinary wear.

What is a Cubic Zirconia?

There are many qualities of diamonds that Cubic Zirconia shares with them. Synthetic materials are created in laboratories, so this material is synthetic. In the 1970s, CZ began to be commercially produced due to increased demand.

It is called faux, fake, imitation, and stimulant because it mimics diamonds but is not the same material. A mistaken representation of cubic zirconia as a diamond or some other gemstone could result in a problem purchase.

The Comparison between Moissanite and Cubic Zirconia (CZ)

Moissanite and cubic zirconia is not equivalent to natural diamonds and genuine jewels. Although, to the common eye, their optical characteristics make it hard to differentiate the three gemstones.

Let’s have a look at different characters.

Color and Clarity

Gemologists rate white stones on a variety graph that moves from D to Z. Gemstones with a D rating are dry. Precious stones with a D rating are uncommon and extraordinarily costly. Almost all cubic zirconia have a D variety rating. Moissanite is seldom dry or straightforward.


The stones, as a rule, have a color of green, dim, or yellow and are very much like jewels. Due to the D rating, CZs can look unnatural. In any case, numerous purchasers do like the drab appearance.


Hued precious stones have become famous as of late. Moissanite and cubic zirconia likewise come in a few well-known colors, but for a portion of the cost of shaded precious stones. The two stones come in blue, purple, pink, brown, golden, and champagne.

Moissanites have a PSI rating of 7.6, showing they are solid under outrageous tension. On the other hand, CZs have a PSI rating of 2.4. Looking at the hardness of the two diamonds, Cubic Zirconia is not exactly half as sturdy as moissanite.


Hardness likewise gauges how likely a stone is to scratch or separate under synthetic or temperature changes. Since zirconium dioxide has a lower rating, they have less protection from these limits. Compared with Cubic Zirconia, Moissanite is 219% harder and more than 300% more impervious to chipping.

Reaction to Dirt

After some time, with the collection of soil and grime, both moissanite and CZ can take on an overcast, foggy appearance. This can emerge out of family cleansers, beauty care products, body oils, residue, etc., making the stones lose their radiance and seem dull.


Moissanite is better prepared to oppose soil than CZ. Cubic Zirconia mists over effectively and loses its radiance at a quicker rate. It should be cleaned considerably more often than moissanite to keep it sparkling.

Light Performance

The RI of a gemstone estimates how much light is twisted as it goes through the gemstone and is a mark of the gemstone's splendor. Moissanite has a Refractive Index (RI) of 2.65, while precious stones' RI is lower at 2.42.


Moissanite has an incredibly elevated degree of brightness and brilliant light execution. This is one explanation why it is number one in wedding bands, as it has a lot higher brightness and fire than a precious stone.

Price and Value

Compared with precious stones, both moissanite and cubic zirconia are significantly more reasonable. Nonetheless, moissanite is, in many cases, considerably more costly than cubic zirconia. A great moissanite carat can retail for around $400, while a comparative estimated Cubic Zirconia will cost around $20 to $40. Cubic zirconia is, by and large, useless and has no resale value.


It's important to remember that moissanite is a stone in its own right and requires cutting-edge innovation, mastery, and a significant expense to orchestrate. It just costs around 10% of the cost of a precious stone. As may be obvious, moissanite is practically 90% more affordable than a precious stone.
