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

Introduction

Can true luxury also be truly ethical? As we navigate the evolving landscape of fine jewellery, this question resonates deeply with many of us who seek beauty without compromising our values. In recent years, the push towards sustainable, conflict-free gemstones has led to a surge in interest surrounding lab-grown diamonds and their alternatives. Among the most discussed options is cubic zirconia, often mistaken for lab-created diamonds.

Are you dreaming of a piece of jewellery that’s as unique as your story? Understanding the differences between these two gemstones is crucial for making informed choices that align with our commitment to ethical luxury. At DiamondsByUK, we pride ourselves on offering stunning, IGI-certified lab-grown diamonds that not only shine brilliantly but also uphold our core values of sustainability and integrity.

This blog post will delve deep into the world of lab-created diamonds and cubic zirconia, exploring their origins, characteristics, and why one is not merely a substitute for the other. We will also highlight how our bespoke design process can help you create a unique piece that reflects your individuality.

Let’s embark on this journey to uncover the truth behind lab-created diamonds and cubic zirconia, ensuring that your next jewellery purchase is both meaningful and beautiful.

What Are Lab Created Diamonds?

Lab-created diamonds, also known as synthetic or cultured diamonds, are real diamonds that share the same physical, chemical, and optical properties as natural diamonds. They are made almost entirely of pure carbon, just like their mined counterparts. The creation process involves replicating the natural conditions under which diamonds form—extreme pressure and high temperatures—using advanced technology.

The Creation Process

There are two primary methods used to create lab-grown diamonds:

1. High Pressure High Temperature (HPHT): This method mimics the natural diamond formation process by applying immense pressure and temperature to carbon. A diamond seed is placed in a chamber with carbon, and the conditions simulate those found deep within the Earth.
2. Chemical Vapor Deposition (CVD): This technique involves introducing a gas mixture (usually hydrogen and carbon) into a vacuum chamber. The gases are ionized to form a plasma, allowing carbon atoms to deposit onto a diamond seed, gradually building a diamond crystal layer by layer.

Both methods result in stunning diamonds that are indistinguishable from natural ones without specialized equipment. At DiamondsByUK, our lab-grown diamonds are IGI certified, ensuring their quality and authenticity.

Characteristics

• Hardness: Lab-grown diamonds score a perfect 10 on the Mohs scale, making them one of the hardest materials on Earth.
• Sparkle: The brilliance and fire of lab-grown diamonds are equivalent to those of natural diamonds, providing that coveted sparkle.
• Ethical Sourcing: All our lab-grown diamonds are conflict-free and environmentally friendly, aligning with our commitment to sustainability.

What Is Cubic Zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that is often used as a diamond simulant due to its sparkling appearance and affordability. However, it is important to clarify that cubic zirconia is not a diamond; its chemical composition is entirely different.

The Creation Process

Cubic zirconia is produced through a process that involves melting zirconium oxide powder along with stabilizers such as calcium and magnesium at extremely high temperatures. Once cooled, the resultant crystals are cut and polished to resemble diamonds.

Characteristics

• Hardness: On the Mohs scale, cubic zirconia scores between 8 and 8.5, making it less durable than lab-grown diamonds.
• Appearance: While CZ can mimic the look of a diamond, it often exhibits a rainbow-like effect in its brilliance, which is different from the white light reflection of a diamond.
• Price: CZ is significantly less expensive than lab-grown diamonds, often costing only a fraction of the price.

Lab Diamonds vs. Cubic Zirconia: Key Differences

Despite their similar appearances, lab diamonds and cubic zirconia possess significant differences that set them apart. Here’s a closer look at these distinctions:

1. Chemical Composition

• Lab Diamonds: Composed of pure carbon, they share the same chemical properties as natural diamonds.
• Cubic Zirconia: Made from zirconium dioxide, CZ does not contain carbon and lacks the authentic diamond characteristics.

2. Hardness and Durability

• Lab Diamonds: With a hardness of 10, they are highly resistant to scratches and damage.
• Cubic Zirconia: Scoring 8-8.5, CZ is vulnerable to scratching and may lose its luster over time.

3. Brilliance and Sparkle

• Lab Diamonds: The brilliance of a lab-grown diamond comes from its precise cut, allowing it to refract light beautifully.
• Cubic Zirconia: Although CZ is sparkly, it often displays a more colorful dispersion compared to the more refined sparkle of real diamonds.

4. Value Retention

• Lab Diamonds: While prices can fluctuate, lab-grown diamonds hold more intrinsic value due to their real diamond nature.
• Cubic Zirconia: CZ has little to no resale value, as it is primarily seen as a fashion accessory rather than a precious stone.

5. Ethical Considerations

• Lab Diamonds: At DiamondsByUK, we ensure that all our lab-grown diamonds are ethically sourced, conflict-free, and environmentally conscious.
• Cubic Zirconia: While CZ is also man-made, it does not carry the same ethical implications as lab-grown diamonds.
