Cubic Zirconia vs Moissanite vs Diamond: A Comparison Guide
Navigating the glimmering world of precious stones can be quite a task. In this journey, we delve into the cubic zirconia vs moissanite conundrum, introducing the age-old diamond into the mix for an insightful comparison.
History and Origin of the Three Stones
Firstly, diamonds, famed for their natural brilliance and durability, have long been mined and cherished. Conversely, cubic zirconia, a synthetic gem, burst onto the scene in the 1970s as a diamond alternative. Moissanite, discovered in a meteor crater by Henri Moissan in the late 19th century, is another synthetic stone often compared to diamonds due to its similar properties.
Physical and Optical Properties
Cubic Zirconia

Moissanite, another synthetic stone, was initially discovered in a meteor crater, leading to its reputation as a “gem from the stars”. Physically, it’s nearly as hard as a diamond, with a 9.25 hardness rating on the Mohs scale, making it highly resistant to scratches and suitable for everyday wear.
In terms of optical properties, moissanite surpasses even diamonds. It has a higher refractive index, leading to a brilliant sparkle, and it also has a higher dispersion, resulting in exceptional fire and giving it a distinctive, intense sparkle. However, this can make it appear slightly different from a diamond, especially under certain lighting conditions.

Diamonds, being natural stones, are unique and vary widely in their physical and optical properties. They are the hardest known material, scoring a 10 on the Mohs scale, which makes them incredibly durable and resistant to scratches. Optically, diamonds exhibit a high refractive index, which contributes to their famed brilliance. They have a lower dispersion than both cubic zirconia and moissanite, which results in less visible fire and a more subdued sparkle.
However, the brilliance and fire of a diamond can be greatly affected by its cut quality. Diamonds come in a range of colors, from colorless to slightly yellow or brown, and also in fancy colors such as blue, green, and pink.
They can also range from flawless to included, with the presence of internal or external flaws known as inclusions and blemishes. The highest-quality diamonds, known as flawless diamonds, have no inclusions or blemishes visible under 10x magnification.

1. Cubic Zirconia vs Moissanite vs Diamond: Hardness and Durability
Diamond
Renowned for their unmatchable hardness, diamonds score a perfect 10 on the Mohs scale. This remarkable hardness makes diamonds extremely resistant to scratches, maintaining their polished, pristine finish over decades and even centuries.
Diamonds are the epitome of durability, able to withstand daily wear and tear with minimal damage. Their resilience extends to high temperatures and pressures, contributing to their enduring appeal and longevity. However, despite their hardness, diamonds can chip or break if hit at certain angles with sufficient force.
Moissanite
A worthy contender to diamonds in terms of hardness, moissanite has a Mohs scale rating of 9.25. This hardness makes it highly resistant to scratches and suitable for daily wear, much like a diamond.
Moissanite’s durability is impressive, it can withstand exposure to heat and everyday chemicals, making it a practical choice for all types of jewelry, including rings and bracelets that experience heavy wear. While not as hard as a diamond, its resilience to wear and tear is significantly better than many other gemstones and simulants.
Cubic Zirconia
With a rating of 8.5 on the Mohs scale, cubic zirconia (CZ) is reasonably hard and should resist most scratches. However, when compared to diamonds and moissanite, CZ falls short in terms of scratch resistance and durability. Over time, cubic zirconia may show wear, including scratches and abrasions, and it can also become cloudy, losing some of its original brilliance.
It’s worth noting that despite its lower hardness rating, cubic zirconia still offers decent durability and is suitable for use in all types of jewelry. Its affordability also means it can be replaced easily if it gets too worn or damaged.
2. Cubic Zirconia vs Moissanite vs Diamond: Brilliance and Fire
Diamond
A diamond’s brilliance is renowned. Its high refractive index contributes to its radiant sparkle, captivating the eye. However, diamonds have a lower dispersion than moissanite and cubic zirconia, which means their fire, or the splitting of light into spectral colors, is less intense.
This gives diamonds a balanced sparkle that’s neither too dull nor too intense, contributing to their timeless appeal. The brilliance and fire of a diamond can be greatly affected by its cut quality.
Moissanite
Moissanite stands out for its exceptional brilliance and fire. With a higher refractive index than diamonds, moissanites exhibit more brilliance, meaning they reflect more light. Their high dispersion gives moissanite a fiery rainbow sparkle, even more so than diamonds and cubic zirconia. Under certain light conditions, this intense fire can give moissanite a slightly different sparkle than diamonds, which some people prefer and others do not.
Cubic Zirconia
Cubic Zirconia also boasts high brilliance due to its high refractive index. In terms of fire, cubic zirconia outperforms diamonds, displaying an impressive play of spectral colors. However, the high dispersion of cubic zirconia sometimes gives it an overly bright appearance, which can make it look less natural than a diamond.
3. Cubic Zirconia vs Moissanite vs Diamond: Cut and Shape
Diamond
Diamonds can be cut into a wide variety of shapes, from traditional round brilliants to fancy shapes like princess, pear, oval, marquise, and more. The cut of a diamond significantly impacts its brilliance, and a well-cut diamond can maximize light return, enhancing its sparkle.
Moissanite
Like diamonds, moissanite can be cut into almost any shape, including round, cushion, radiant, and pear, among others. Moissanite cuts often aim to enhance its brilliance and fire, with round and oval cuts being popular for maximizing these qualities.
Cubic Zirconia
Cubic Zirconia is easy to cut and can mimic any diamond shape, from traditional to fancy cuts. Often, cubic zirconia is cut to mimic popular diamond cuts and maximize its brilliance and fire.
4. Cubic Zirconia vs Moissanite vs Diamond: Clarity and Color
Diamond
Diamonds occur naturally in a wide range of colors and clarity grades. Color ranges from colorless to slightly yellow or brown, and fancy colors such as blue, green, and pink are also found.
