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[1]. 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[2].
-
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[2].
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.

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.
Clarity Grade
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
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
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[1]. 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.
-
Brilliance: Lab-grown diamonds exhibit exceptional brilliance due to their optical properties, similar to natural diamonds. Their ability to reflect light creates a stunning sparkle that rivals mined diamonds. Cubic zirconia also has excellent brilliance but may lack the fire and scintillation of lab-grown or natural diamonds.
-
Long-term value: Lab-grown diamonds retain their value over time since they possess all the qualities of natural diamonds. They can be considered an investment piece that holds its worth over the years. On the other hand, cubic zirconia does not hold long-term value as it is not a genuine diamond alternative.
-
Ethical considerations: Lab-grown diamonds offer an ethical alternative to mined diamonds by avoiding environmental damage and human rights issues associated with traditional diamond mining practices.
While lab-grown diamonds may be more expensive than cubic zirconia initially, they provide a more valuable and ethical option for those seeking diamond alternatives. It is essential to consider factors such as durability, brilliance, and long-term value before making a purchase decision.
