Are Lab Grown Diamonds the Same as Cubic Zirconia? Understanding the Differences

Introduction

Can true luxury also be truly ethical? As consumers become increasingly conscious of their purchasing choices, the jewellery industry is experiencing a significant shift towards sustainability and ethical sourcing. More and more of us are seeking unique pieces that not only reflect our personal style but also align with our values. This raises an important question: Are lab-grown diamonds the same as cubic zirconia?

Understanding the differences between these two popular alternatives to natural diamonds is crucial for anyone looking to make informed and ethical jewellery choices. At DiamondsByUK, we are committed to redefining luxury by making sustainable, conflict-free diamond jewellery accessible to all. Our mission is to lead a shift in the jewellery industry towards more responsible practices, which includes educating our customers about the choices available to them.

In this blog post, we will explore the characteristics, manufacturing processes, and value propositions of lab-grown diamonds and cubic zirconia. We will also discuss how our bespoke design services at DiamondsByUK can help you create the perfect piece that tells your unique story. Are you dreaming of a piece of jewellery that’s as unique as your love story? Let’s dive into this fascinating topic and discover what makes lab-grown diamonds stand apart from cubic zirconia.

What Are Lab Grown Diamonds?

Lab-grown diamonds, also known as synthetic or cultured diamonds, are real diamonds created in controlled laboratory environments. The process mimics the natural formation of diamonds, which occurs deep within the Earth over millions of years. Lab-grown diamonds are made from carbon, just like natural diamonds, and share the same physical, chemical, and optical properties. This means they are graded using the same criteria as natural diamonds, including the 4Cs: Carat, Cut, Clarity, and Colour.

How Are Lab Grown Diamonds Made?

Lab-grown diamonds are produced using one of two primary methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).

• HPHT Method: This method simulates the natural conditions that create diamonds by applying high pressure and temperature to carbon. A tiny diamond seed is placed in a chamber with carbon, and over time, the carbon crystallizes around the seed, forming a diamond.
• CVD Method: This process involves placing a diamond seed in a chamber filled with carbon-rich gas. The gas is heated, causing carbon atoms to settle on the seed and form a diamond layer by layer.

Both methods yield diamonds that are chemically identical to natural diamonds, and they can be crafted into exquisite pieces of jewellery, including engagement rings, earrings, and necklaces.

The Value of Lab Grown Diamonds

At DiamondsByUK, we specialize in IGI-certified lab-grown diamonds, ensuring our customers receive high-quality stones that are both beautiful and ethically sourced. Lab-grown diamonds are typically priced lower than their natural counterparts, making them an excellent choice for budget-conscious consumers. They also come with the added advantage of being conflict-free, giving you peace of mind that your purchase does not contribute to human rights abuses.

What Is Cubic Zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that is often used as a diamond simulant. Although it can closely resemble a diamond in appearance, it is fundamentally different in composition and properties. Cubic zirconia is made from zirconium dioxide, which is melted and cooled to form crystals that are then cut and polished.

Characteristics of Cubic Zirconia

• Composition: Unlike lab-grown diamonds, cubic zirconia does not contain carbon. Its chemical structure is entirely different, which contributes to its distinct properties.
• Hardness: On the Mohs scale of hardness, cubic zirconia ranks between 8 and 8.5, making it less durable than lab-grown diamonds, which score a perfect 10. This means CZ can be more prone to scratching and damage over time.
• Brilliance: Cubic zirconia exhibits a higher dispersion of light than diamonds, resulting in a more colourful sparkle, sometimes referred to as a "rainbow effect." While this can be visually striking, it may appear artificial compared to the more subtle brilliance of a diamond.

The Value of Cubic Zirconia

Cubic zirconia is significantly cheaper than lab-grown diamonds, making it an attractive option for consumers who desire the look of a diamond without the associated cost. However, it is important to note that CZ holds little to no resale value, as its market demand is primarily for its aesthetic appeal rather than its inherent qualities.

Key Differences Between Lab Grown Diamonds and Cubic Zirconia

Now that we have a foundational understanding of both lab-grown diamonds and cubic zirconia, let’s explore the key differences that set them apart.

1. Composition and Structure

• Lab Grown Diamonds: Made from pure carbon, lab-grown diamonds share the same chemical structure as natural diamonds, making them true diamonds in every sense.
• Cubic Zirconia: Comprised of zirconium dioxide, CZ is not a diamond and lacks the same physical and chemical properties.

2. Hardness and Durability

• Lab Grown Diamonds: Scoring a 10 on the Mohs scale, lab-grown diamonds are extremely durable and resistant to scratches and damage.
• Cubic Zirconia: With a hardness rating of 8-8.5, CZ is more prone to scratching and may require more frequent cleaning and maintenance.

3. Brilliance and Sparkle

• Lab Grown Diamonds: Exhibiting a natural brilliance and fire, lab-grown diamonds reflect light in a way that is indistinguishable from natural diamonds.
• Cubic Zirconia: Known for its rainbow-like sparkle due to higher dispersion, CZ can appear overly flashy compared to the understated elegance of diamonds.

4. Value and Investment

• Lab Grown Diamonds: As real diamonds, lab-grown options retain value and can be resold. They offer a more ethical alternative to mined diamonds without sacrificing quality.
• Cubic Zirconia: CZ has little to no resale value and is primarily valued for its appearance rather than its composition.

5. Ethical Considerations

• Lab Grown Diamonds: Being conflict-free and environmentally friendly, lab-grown diamonds align with ethical consumerism and sustainability.
• Cubic Zirconia: While CZ is also a synthetic product, it does not offer the same ethical assurances as lab-grown diamonds.
