Is a Cubic Zirconia a Lab Created Diamond? Understanding the Differences

Introduction

In an age where ethical consumerism is becoming increasingly important, many individuals are seeking alternatives to traditional mined diamonds. Are you dreaming of a piece of jewellery that’s as unique as your story, yet aligns with your values? At DiamondsByUK, we believe that luxury should be sustainable and accessible, and we are proud to offer lab-grown diamonds that are both ethically sourced and beautifully crafted.

As you embark on your journey to find the perfect gemstone, you may find yourself asking, "Is a cubic zirconia a lab created diamond?" This question is more common than you might think, and it's essential to understand the significant differences between these two types of stones.

In this blog post, we will delve into the world of diamonds and their alternatives, focusing on the distinctions between cubic zirconia (CZ) and lab-grown diamonds. We will explore their composition, appearance, durability, ethical considerations, and how our customization process at DiamondsByUK can help you design the perfect piece of jewellery for your unique needs.

Let’s embark on this journey together, as we redefine luxury through sustainable practices and exquisite craftsmanship.

What Are Lab-Grown Diamonds?

Lab-grown diamonds, also known as synthetic or cultured diamonds, are real diamonds created in controlled environments using advanced technology. Unlike mined diamonds that form naturally over millions of years under extreme heat and pressure deep within the Earth, lab-grown diamonds are produced through two primary processes: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

The Creation Process

1. High Pressure High Temperature (HPHT): This method replicates the natural diamond-growing conditions. A small diamond seed is placed in carbon and subjected to intense heat and pressure, resulting in the formation of a diamond.
2. Chemical Vapor Deposition (CVD): In this process, a diamond seed is placed in a chamber filled with carbon-rich gases. The gases are heated to create a plasma, which causes carbon atoms to deposit on the seed, forming a diamond.

The result is a diamond that shares the same physical, chemical, and optical properties as natural diamonds, making them indistinguishable even to trained gemologists. At DiamondsByUK, all our lab-grown diamonds are IGI-certified, ensuring you receive a stone of the highest quality.

The 4Cs of Diamonds

When evaluating diamonds, whether natural or lab-grown, it’s essential to consider the 4Cs: Cut, Color, Clarity, and Carat weight.

• Cut: Refers to how well the diamond has been shaped and faceted. A well-cut diamond will reflect light beautifully.
• Color: Lab-grown diamonds can be colorless or exhibit subtle hues. They are graded on a scale from D (colorless) to Z (light yellow or brown).
• Clarity: This measures the presence of internal or surface flaws. Lab-grown diamonds can achieve higher clarity ratings due to the controlled growing environment.
• Carat Weight: This indicates the size of the diamond, with one carat equalling 0.2 grams.

With our commitment to sustainability and transparency, we ensure that you receive a diamond that not only meets your aesthetic preferences but also aligns with your ethical values.

What Is Cubic Zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that is often used as a diamond simulant. While it may appear similar to a diamond at first glance, it is important to understand that CZ is not a diamond and possesses a different chemical composition.

The Creation Process

Cubic zirconia is produced by melting zirconium oxide powder along with stabilizers like magnesium and calcium at extremely high temperatures (around 4,982°F). The resulting crystals are then cut and polished to mimic the appearance of diamonds. Unlike lab-grown diamonds, CZ does not contain carbon and thus lacks the same physical and chemical characteristics.

Characteristics of Cubic Zirconia

• Appearance: While CZ can be cut to resemble diamonds, it often exhibits a different kind of brilliance. Cubic zirconia has a higher dispersion rate than diamonds, meaning it can show more colorful flashes of light, which some may find appealing, while others may view it as less authentic.
• Hardness: On the Mohs scale of hardness, cubic zirconia ranks between 8 and 8.5. This makes it less durable than diamonds, which score a perfect 10, meaning CZ is more susceptible to scratches and abrasions over time.
• Cost: One of the main attractions of cubic zirconia is its affordability. CZ is significantly less expensive than both lab-grown and natural diamonds, making it an attractive option for budget-conscious consumers.

While cubic zirconia can serve as a beautiful alternative for costume jewellery, it is essential to recognize that it lacks the longevity and true value of lab-grown diamonds.

Comparing Cubic Zirconia and Lab-Grown Diamonds

Now that we've established what lab-grown diamonds and cubic zirconia are, let's break down the key differences between the two.

1. Composition

• Lab-Grown Diamonds: Composed of pure carbon and share the same molecular structure as natural diamonds. They are classified as real diamonds.
• Cubic Zirconia: Made from zirconium oxide and is not a diamond in any sense. It is a simulant created to imitate the appearance of diamonds.

2. Appearance

• Brilliance: Lab-grown diamonds exhibit a brilliance that is natural and complex due to their structure. Cubic zirconia tends to show a rainbow-like effect due to its higher dispersion, which can appear artificial to some observers.
• Inclusions: Most lab-grown diamonds will have some inclusions, which are natural imperfections, while CZ is usually flawless.

3. Durability

• Lab-Grown Diamonds: Scoring a 10 on the Mohs scale, they are incredibly durable and resistant to scratches and chips.
• Cubic Zirconia: Scoring between 8 and 8.5, CZ is more prone to scratches and may lose its luster over time.

4. Value

• Lab-Grown Diamonds: These diamonds maintain a significant value due to their real diamond status and can be resold. They are also typically more affordable than natural diamonds, allowing you to invest in quality without compromising your budget.
• Cubic Zirconia: While CZ is inexpensive, it has little to no resale value, as it is not considered a precious gemstone.

5. Ethical Considerations

• Lab-Grown Diamonds: These are 100% conflict-free and produced with a focus on sustainability, making them an excellent choice for the ethically-minded consumer.
• Cubic Zirconia: While CZ is also man-made, it does not carry the same ethical considerations as lab-grown diamonds, which can be traced back to a transparent production process.
