How to Choose Between Moissanite vs. Cubic Zirconia

Moissanite vs. cubic zirconia

People who like gemstones often look for alternatives to diamonds in their search for the right sparkle. Moissanite and cubic zirconia are two popular choices that have gotten a lot of attention for how beautiful they are and how cheap they are. By knowing the differences between Moissanite vs. cubic zirconia, you can make an informed choice about which stone is best for your jewelry.

Origins and Composition

Moissanite and cubic zirconia are both popular alternatives to diamonds, but their origins and composition are very different. Here is the basic origin of Moissanite vs. cubic zirconia:

Dr. Henri Moissan, a Nobel Prize-winning chemist, found moissanite in a meteorite hole in 1893. Moissanite is a naturally occurring mineral made of silicon carbide. However, the moissanite used in jewelry today is usually made in a lab, which makes sure that the production process is controlled and moral.

Cubic zirconia (CZ), on the other hand, is made completely of man-made materials. Zirconium oxide and yttrium oxide are heated together at very high temperatures to make it. The end result is a crystallized gem that looks a lot like a diamond.

How Hard and Durable It Is

When judging Moissanite vs. cubic zirconia, how hard they are is a key factor that affects how well they fight scratches and normal wear and tear.

Moissanite is very hard, getting a 9.25 out of 10 on the Mohs scale. This makes it a long-lasting jewelry choice that can be worn every day without worrying about getting scratched or broken.

Diamond cubic zirconia is a hard and long-lasting rock, but it rates a little lower on the Mohs scale, at about 8 to 8.5. This means that even though it is strong, it might be easier to scratch than moissanite.

Fire and Brightness

Stone brightness is how well it sparkles and reflects light. In case of Moissanite vs. cubic zirconia, both are brilliant but they react to light differently.

Moissanite shines brighter than diamonds. It diffuses light to create a rainbow. It can be brighter than cubic zirconia due to light interaction.

Cubic zirconia sparkles like diamonds. According to some, cubic zirconia’s brightness may be less intense than Moissanite’s.

Color and Clarity

Moissanite and cubic zirconia can be clear and colorless, looking like diamonds. The way they handle color changes slightly.

Moissanite is usually colorless but can be yellow or green. But advances in moissanite production have made it nearly or completely colorless.

Cubic zirconia is usually clear like the greatest diamonds. It’s ideal for those who desire something clear and white.

Cost of the Product

Cost is a major consideration when buying moissanite or cubic zirconia. These jewels are cheaper than diamonds, though prices vary.

Despite being more expensive than cubic zirconia, moissanite is cheaper than diamonds. Moissanite prices vary by size, color, and quality.

Cubic zirconia is the cheapest alternative for those on a budget who desire a gorgeous diamond. Due to its low cost, larger stones can be created.


The choice between Moissanite vs. cubic zirconia depends on your preferences, priorities, and budget. Cubic zirconia is cheaper but sparkles less than moissanite, which lasts longer and shines brighter. No matter your preferences, hardness, brightness, or price both stones are beautiful and can be the ideal jewelry choice. Understanding the distinctions between cubic zirconia and moissanite can help you choose one that suits your style and values.
