A 3.00-carat cubic zirconia ring may sell for around $200, while a similar diamond ring sells for around $25,000.
CZ engagement rings typically range from $20-$40, depending on the metal of the setting.
Cubic zirconia’s luster diminishes and becomes cloudy within two years of daily use, exacerbated by the absorption of skin oils and everyday products.
Understanding the Difference: Cubic Zirconia vs Diamond Properties
Cubic zirconia and diamonds may both be gemstones, but they have distinct differences in their properties that contribute to variations in price. Cubic zirconia, with a refractive index of 2.15–2.18 and a dispersion rate of 0.058–0.066, exhibits a more pronounced “rainbow effect” compared to diamonds, which have a refractive index of 2.42 and a lower dispersion rate of 0.044. Let’s explore these disparities further:
Cubic Zirconia: Synthetic Gemstone
Cubic zirconia is a man-made gemstone created using zirconium dioxide.
Within two years of daily use, cubic zirconia’s luster diminishes and becomes cloudy, exacerbated by skin oils and common products.
It is synthesized in laboratories under controlled conditions, replicating the appearance of natural diamonds.
While cubic zirconia can resemble diamonds, it lacks the same geological formation process.
A diamond has a Mohs scale rating of 10 and is the hardest naturally occurring mineral, surpassing cubic zirconia, which ranks 8.5 and is denser.
Diamonds: Natural Gems with Superior Hardness
Diamonds are formed deep within the Earth’s crust over millions of years.
They possess a higher hardness rating on the Mohs scale than cubic zirconia, making them more durable and resistant to scratches.
The natural crystalline structure of diamonds allows for superior light refraction, resulting in heightened brilliance and sparkle.
Contrasting Brilliance and Light Refraction
When cut and polished correctly, cubic zirconia and diamonds can exhibit brilliance and sparkle.
However, diamonds have superior light refraction properties due to their crystal structure.
This means that when light enters a diamond, it refracts or bends more effectively than cubic zirconia, creating a captivating play of light.
The unique properties of cubic zirconia and diamonds contribute to their differing prices. While cubic zirconia offers an affordable alternative that closely resembles the appearance of a diamond, its synthetic nature affects its value. On the other hand, natural diamonds have greater rarity and durability due to their geological formation process. These factors make them highly sought after and often more expensive.
Comparing Price and Value: Cubic Zirconia vs Diamond
There are some key factors to consider. Diamonds are known for their rarity in nature, contributing to their higher price than CZ. Typically, CZ engagement rings cost $20-$40, depending on the metal of the setting.The value of a diamond is determined by various factors such as carat weight, color grade, clarity grade, cut quality, and industry standards.
Diamonds: Expensive but Valuable
Diamonds have long been associated with luxury and prestige due to their high price tag. Their rarity makes them highly sought after and desirable. The value of a diamond can appreciate over time, especially if it possesses exceptional qualities such as large carat weight or exceptional clarity.

Cubic Zirconia: More Affordable but Synthetic
On the other hand, cubic zirconia is more affordable compared to diamonds. It is a synthetic material made in laboratories rather than being formed naturally like diamonds. Compared to a similar diamond ring, a 3.00-carat cubic zirconia ring may cost around $200. While CZ may offer a similar appearance to diamonds at a fraction of the cost, its value may not be retained as well over time.
More affordable compared to diamonds
Offers similar visual appeal
Synthetic nature may affect long-term value retention
May lack the prestige associated with diamonds
When choosing cubic zirconia or diamonds based on price versus value, individuals should weigh their budget constraints against their desire for long-term investment potential. While CZ may be more accessible for those on a tight budget or looking for temporary jewelry options, diamonds offer the allure of rarity and potential appreciation in value over time.
“Cubic zirconia, known for its refractive index of 2.15–2.18 and dispersion rate of 0.058–0.066, displays a more noticeable “rainbow effect.”
Factors Influencing Price: Clarity, Color, and Cut
Clarity, color, and cut are three key factors influencing the price of diamonds and cubic zirconia. Let’s take a closer look at each of these factors.
The clarity grade refers to internal flaws or blemishes within a diamond or cubic zirconia. Higher clarity grades indicate fewer imperfections and, therefore, command higher prices. These imperfections can include inclusions (internal flaws) or blemishes (external flaws). The Gemological Institute of America (GIA) uses a scale ranging from Flawless to Included to assess the clarity grade.
Color grading evaluates the presence of any yellow or brown tints in a diamond. The less color present, the higher the price. Diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). Cubic zirconia is typically colorless but can also be produced in various colors.
Cut quality determines how well a diamond or cubic zirconia reflects light and sparkles. A superior cut grade is associated with higher prices because it maximizes brilliance and enhances overall appearance. The cut affects how effectively white light enters the stone, reflects off its facets, and returns to your eye as colored light.
These three factors—clarity grade, color grading, and cut quality—significantly impact the price of both diamonds and cubic zirconia. Cubic zirconia lasts about 2-3 years with everyday wear and up to 5 years with occasional wear. By understanding these factors, you can make an informed decision when purchasing gemstones based on your budget and preferences.
“Experts do not consider cubic zirconia as a substitute for diamonds due to significant differences in chemical properties, brilliance, and color.”
Buying Guide: Lab Diamonds vs Cubic Zirconia
Lab-grown diamonds and cubic zirconia are two popular options for diamond alternatives. While both may have a similar appearance, there are significant differences in their composition and value.
Lab-grown diamonds vs Cubic zirconia: What’s the difference?
Lab-grown diamonds are real diamonds created in a laboratory using advanced technology. They possess the same physical and chemical properties as natural diamonds, making them highly valuable. On the other hand, cubic zirconia is entirely synthetic and lacks the authenticity of lab-grown or natural diamonds.
Considerations before making a purchase decision
When comparing lab-grown diamonds to cubic zirconia, several factors should be taken into account:
Durability: Lab-grown diamonds are extremely durable due to their high-quality composition. They can withstand everyday wear and tear without losing their brilliance. In contrast, cubic zirconia is less durable and may scratch or dull over time.
