Are you in the market for affordable jewelry but unsure about the differences between moissanite and cubic zirconia? In this piece, we will look at the differences and similarities between these two common stone selections. If you're in the market for a necklace or a new addition to your collection, knowing the key differences between moissanite and cubic zirconia will help you make an educated purchase.

What Is Cubic Zirconia?

Cubic Zirconia, often referred to as CZ, is a man-made gemstone that closely resembles a diamond. It was first developed in the 1970s as an affordable alternative to natural diamonds. Cubic Zirconia is created by heating zirconium oxide powder with other specific elements to achieve its crystalline structure.

Cubic Zirconia is known for its tremendous brilliance and fire. Because of its high refractive index, it can reflect a great deal of light, creating a stunning sparkle. This is one of the reasons why Cubic Zirconia is often used as a diamond substitute in jewelry.

The History Of Cubic Zirconia

Cubic Zirconia's history stretches back to the 1970s, when it was developed as a replacement to genuine diamonds. Scientists and gemologists were looking for a means to create a synthetic gemstone with the radiance and beauty of a diamond but at a considerably lower cost. They discovered after years of research and testing that heating zirconium oxide powder with other particular elements resulted in the production of Cubic Zirconia.

Since its creation, Cubic Zirconia has gained popularity as a diamond substitute in jewelry. People looking for high-quality jewelry on a budget often choose to purchase this because of its inexpensive cost and aesthetic similarity to diamonds. Rings, earrings, bracelets, and necklaces are just few of the jewelry pieces where cubic zirconia has found a home.

Moissanite vs Cubic Zirconia What’s The Difference?

Moissanite, on the other hand, is a naturally occurring mineral discovered by French chemist Henri Moissan in 1893. It is a unique gemstone made of silicon carbide. Moissanite, like diamonds, is noted for its extraordinary brilliance and fire. In fact, it is often mistaken for diamonds due to its similar appearance.


One of the primary distinctions between moissanite and cubic zirconia is their chemical composition. Moissanite is a naturally occurring mineral, whereas cubic zirconia is a man-made gemstone. This change in composition can have an impact on the stones' overall durability and lifetime.

Hardness Scale and Durability

If you want to wear your jewelry every day, you should think about how long it will last. Moissanite is known to be one of the hardest gemstones, ranking at 9.25 on the Mohs scale of hardness. This makes it exceptionally tough against damage from impacts and chipping. Cubic zirconia, on the other hand, has a Mohs hardness score between 8 and 8.5, making it slightly softer. Even while it's still sturdy, it scratches more easily and may need more maintenance over time.

Cost and Value

Another difference between moissanite and cubic zirconia is their value. Moissanite is generally more expensive than cubic zirconia due to its rarity and natural occurrence. However, it is still much cheaper than diamonds, therefore it is favored by those on a tighter budget.

Color and Shine

In terms of color, both moissanite and cubic zirconia are available in a range of colors. However, moissanite tends to have a higher level of color saturation and brilliance compared to cubic zirconia. Moissanite has a greater refractive index, which means it bends light more effectively and produces more sparkle and fire.

Clarity and Apperance

When it comes to clarity, both moissanite and cubic zirconia can be found in varying levels of clarity, ranging from flawless to included. However, moissanite tends to have fewer visible inclusions compared to cubic zirconia, which can affect the overall appearance of the stone.

Does Cubic Zirconia Have a Higher Resale Value Than Moissanite?

When it comes to resale value, moissanite generally holds its value better than cubic zirconia. This is because moissanite is a natural gemstone, while cubic zirconia is a synthetic material. Natural gemstones, while not as uncommon as diamonds, keep their value better over time. In addition, moissanite's rising popularity in the jewelry sector and its status as a viable alternative to diamonds boost its secondary market price.

Carat Comparison Moissanite vs Cubic Zirconia

In terms of carat weight, moissanite and cubic zirconia are relatively comparable. Both stones are available in a range of carat sizes, allowing you to choose the size that fits your budget and desired look. However, it is important to note that the price of moissanite increases with carat size, so larger stones may be more expensive compared to cubic zirconia.

Are Cubic Zirconia Considered Simulated Stones?

Yes, cubic zirconia is considered a simulated stone. Simulants are stones that have a similar appearance to real gemstones but are made from different materials. In the case of cubic zirconia, it is made from zirconium dioxide, a synthetic material. While cubic zirconia may closely resemble a diamond in appearance, it is not a natural gemstone.

Does Cubic Zirconia Have More Dispersion Than Moissanite?

The ability of a gemstone to split light into its spectral hues, generating a rainbow-like effect, is referred to as dispersion. When it comes to dispersion, moissanite has a higher rating than cubic zirconia. Moissanite's high refractive index allows for greater light dispersion, resulting in a more pronounced rainbow effect when compared to cubic zirconia. This is one among the characteristics that contribute to moissanite's exceptional sparkle and fire, making it a popular choice for individuals looking for a diamond substitute with a lot of flashes and brilliance.

How Can I Maintain My Cubic Zirconia

Avoid Harsh Chemicals

Cubic zirconia can be damaged by harsh chemicals found in cleaning products, so it's important to remove your jewelry before using any cleaning solutions or chemicals. This includes household cleaners, beauty products, and even chlorine from swimming pools.

Store Properly

When you're not wearing your cubic zirconia jewelry, it's important to store it properly to prevent scratches and damage. Ideally, you should store your jewelry in a soft pouch or jewelry box, away from other pieces that could potentially scratch it.

Clean Regularly

To keep your cubic zirconia jewelry looking its best, you should clean it regularly. You can use a gentle jewelry cleaner or simply soak it in warm soapy water and then gently scrub with a soft brush. Be sure to rinse thoroughly and dry with a soft cloth to prevent water spots.

Avoid Rough Handling

While cubic zirconia is durable, it can still be chipped or scratched if not handled with care. Avoid wearing your jewelry during activities that could potentially cause damage, such as sports or heavy labor.


In conclusion, both moissanite and cubic zirconia are popular alternatives to diamonds in jewelry. While cubic zirconia offers affordability and a close visual resemblance to diamonds, moissanite offers exceptional brilliance, durability, and sustainability. The choice between the two ultimately depends on personal preferences and budget. Whether you choose moissanite or cubic zirconia, you can enjoy the beauty and sparkle of a high-quality gemstone without breaking the bank.
