Moissanite Vs Diamond Vs Cz: Sparkle Showdown

Moissanite, diamond, and CZ are three popular gemstone alternatives with unique qualities. Moissanite is a lab-created gemstone known for its brilliance and affordability, while diamonds are natural gemstones revered for their rarity and durability.

Meanwhile, CZ (cubic zirconia) is an inexpensive synthesized gemstone that mimics the appearance of a diamond but lacks the same durability and authenticity. Now, let’s explore these options in more detail to understand their key differences and make an informed choice.

Composition And Structure

Understanding the composition and structure of moissanite, diamond, and CZ is crucial when it comes to choosing the perfect gemstone for your jewelry. Let’s delve into the unique qualities of each and discover what sets them apart.


Moissanite is a brilliant gemstone that occurs naturally in meteorites but is predominantly synthesized in laboratories. Composed of silicon carbide (SiC), it possesses a distinct crystal structure. Moissanite’s chemical formula and formation result in exceptional hardness and brilliance.

With a hardness of 9.25 on the Mohs scale, moissanite is one of the hardest substances on Earth, outranking both diamond and CZ. Its crystal lattice structure contributes to its exceptional refractive index, giving it unparalleled sparkle and fire.


Diamonds, often referred to as “a girl’s best friend,” are treasured for their timeless beauty and incredible strength. Composed solely of carbon atoms, diamonds are formed deep within the Earth’s mantle under extreme pressure and high temperatures.

The unique structure of a diamond forms a perfect cubic crystal lattice, making it the hardest known natural material with a rating of 10 on the Mohs scale. This exceptional hardness, combined with the diamond’s ability to reflect and refract light, creates its mesmerizing brilliance.


Cubic Zirconia (CZ) is a popular diamond alternative due to its affordability and likeness to diamonds. Unlike moissanite and diamond, CZ is a laboratory-grown stone made from zirconium dioxide (ZrO2).

The crystal structure of CZ is cubic, resulting in a hardness of around 8 to 8.5 on the Mohs scale. Although CZ offers excellent clarity and is available in various colors, it lacks the fire and brilliance of moissanite and diamond. However, its affordability makes it a preferred choice for budget-conscious individuals.

Brief Comparison:

Gemstone Composition Structure Mohs Hardness Brilliance
Moissanite Silicon Carbide (SiC) Crystal lattice structure 9.25 Exceptional
Diamond Carbon Cubic crystal lattice 10 Mesmerizing
CZ Zirconium Dioxide (ZrO2) Cubic structure 8-8.5 Good

Comparing these gemstones’ composition and structure provides valuable insight into their unique qualities. Each stone offers distinct attributes, allowing you to select the perfect gemstone that aligns with your preferences and budget.

Physical Properties

Moissanite, diamond, and CZ each have unique physical properties. These gemstones differ in terms of hardness, brilliance, and durability, making them distinct choices for jewelry. Understanding these differences can help you make an informed decision when selecting the perfect stone for your needs.


When it comes to choosing the perfect gemstone for engagement rings or other jewelry, it’s important to consider their physical properties. The three most popular options on the market are Moissanite, Diamond, and Cubic Zirconia (CZ). Each of these gemstones has its own unique physical properties that make them stand out. In this blog post, we will explore and compare the brilliance and fire, hardness and durability, and color range of Moissanite, Diamond, and CZ.

Brilliance And Fire

Brilliance refers to the ability of a gemstone to reflect light while fire refers to the colorful flashes of light it emits. When it comes to brilliance and fire, diamonds are known to have the highest rating. However, Moissanite closely rivals the brilliance of diamonds, often considered a good alternative due to its exceptional light-refracting properties. On the other hand, Cubic Zirconia also exhibits a noticeable amount of brilliance and fire, but not to the same degree as Moissanite or Diamond.

Hardness And Durability

The hardness and durability of a gemstone are crucial factors to consider, especially for jewelry that is meant to be worn daily. Diamonds are the hardest gemstones, ranking 10 on the Mohs Scale of Hardness, making them more resistant to scratches and chips. Moissanite, with a score of 9.25, comes in a close second. Cubic Zirconia, although relatively durable, is not as hard as Moissanite or Diamond, earning a rating of around 8 on the Mohs Scale. This means it can be more prone to scratches and may require extra care.

Color Range

When it comes to color range, diamonds and Moissanite offer a wider variety compared to Cubic Zirconia. Diamonds are available in various colors, ranging from colorless to shades of yellow and brown, as well as fancy colors like blue, pink, and green. On the other hand, Moissanite offers a similar color range, but also incorporates options for yellow and gray hues. Cubic Zirconia, although it can mimic the colorless appearance of a diamond, lacks the color spectrum found in Moissanite and Diamond.

In conclusion, Moissanite, Diamond, and Cubic Zirconia each have their own unique physical properties. When considering brilliance and fire, diamonds reign supreme, but Moissanite comes close in providing an exceptional sparkle. In terms of hardness and durability, diamonds are the most durable, followed by Moissanite and Cubic Zirconia. Finally, when it comes to color range, both Moissanite and diamonds offer a wide variety of options, while Cubic Zirconia lacks the diverse color spectrum. Ultimately, the choice between these gemstones will depend on personal preferences, budget, and desired appearance.

Cost And Value

In the jewelry market, cost and value are crucial considerations when weighing the options of Moissanite, Diamond, and CZ. Let’s delve into the pricing comparison and factors impacting the value of these gemstones to gain a better understanding of their worth.

Pricing Comparison

When it comes to cost, Moissanite is generally more affordable than diamonds, without compromising on brilliance. On the other hand, Cubic Zirconia (CZ) falls on the lower end of the pricing spectrum due to its inferior durability and likeness to real diamonds. The pricing comparison table below provides a visual representation of the cost disparity among these gemstones.

Gemstone Average Price per Carat
Diamond Expensive
Moissanite Affordable
Cubic Zirconia (CZ) Inexpensive

Factors Impacting Value

  • Durability: Moissanite ranks high in durability, making it a valuable choice for everyday wear.
  • Brilliance: Both Moissanite and diamonds exhibit exceptional brilliance, contributing to their perceived value.
  • Perceived Rarity: The rarity of diamonds adds an intrinsic value, while Moissanite’s availability affects its pricing.
  • Resale Value: Diamonds typically hold better resale value compared to Moissanite and CZ.
  • Ethical Considerations: Increasingly, consumers place value on ethically sourced gemstones, favoring Moissanite over diamonds due to its conflict-free nature.

Ethical And Environmental Considerations
