What's the Difference Between Cubic Zirconia and Lab Created Diamonds?

Introduction

Can true luxury also be truly ethical? This question has become increasingly relevant in a world where consumers are more conscious than ever about the origins of their purchases. As we seek to redefine luxury with sustainable choices, the jewelry industry has witnessed a remarkable shift toward responsible practices. At DiamondsByUK, our mission is to make sustainable, conflict-free diamond jewelry accessible to all, ensuring that every piece we create resonates with our values of integrity, craftsmanship, and customer focus.

When it comes to choosing the perfect gemstone for an engagement ring or any special piece, many people find themselves pondering the differences between lab-created diamonds and cubic zirconia (CZ). Are they merely different names for the same thing, or do they represent two distinct categories of stone? Are you dreaming of a piece of jewelry that’s as unique as your story? In this comprehensive guide, we will delve deep into the essential differences between cubic zirconia and lab-created diamonds, empowering you to make informed decisions when it comes to your jewelry choices.

With our commitment to sustainability and craftsmanship, we at DiamondsByUK offer IGI-certified lab-grown diamonds that embody beauty without compromising ethical values. Our bespoke design service allows you to create a truly unique piece, often with delivery in just 1-2 weeks. Let's explore the world of these two sparkling alternatives and discover why lab-grown diamonds are the ethical choice for modern consumers.

Understanding Cubic Zirconia (CZ)

Cubic zirconia, often referred to as CZ, is a synthetic material that was originally developed in Russia in the 1970s. It is made from zirconium dioxide, which is melted and then crystallized to form a stone that can be cut and polished to mimic the appearance of diamonds. While CZ is often lauded for its affordability and visual appeal, it is crucial to understand its fundamental differences from lab-created diamonds.

The Composition of Cubic Zirconia

Unlike diamonds, which are made primarily of carbon, cubic zirconia has a different chemical structure. CZ is a crystalline form of zirconium dioxide, and while it is colorless and can appear visually similar to a diamond, it lacks the same physical characteristics. For example, cubic zirconia does not contain carbon and thus does not possess the same durability or brilliance as diamonds.

Properties of Cubic Zirconia

  1. Hardness: On the Mohs scale of hardness, CZ ranks between 8 and 8.5. While this makes it a relatively hard material, it is still softer than diamonds, which score a perfect 10. This means that CZ is more prone to scratching and may require more frequent cleaning to maintain its shine.
  2. Brilliance and Sparkle: Cubic zirconia has a higher dispersion rate than diamonds, which gives it a more colorful sparkle, often described as a "rainbow effect." However, this characteristic is a telltale sign that a stone is not a diamond, as diamonds exhibit a more subtle and refined brilliance.
  3. Color: CZ is typically colorless but can be artificially colored to mimic various gemstones. Unlike lab-grown diamonds that can be graded on a spectrum from D (colorless) to Z (light yellow), CZ does not have this range and is often flawless in appearance.
  4. Value: Due to its synthetic nature and low production costs, cubic zirconia is significantly less expensive than both lab-grown and natural diamonds. While it may be a budget-friendly option, its resale value is virtually non-existent.

Understanding Lab-Created Diamonds

Lab-created diamonds are real diamonds that are produced in controlled environments using advanced technology. They share the same physical, chemical, and optical properties as natural diamonds, making them indistinguishable from their mined counterparts to the naked eye.

The Composition of Lab-Created Diamonds

Lab-created diamonds are composed entirely of carbon atoms, just like natural diamonds. They are created using one of two primary methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). Both processes simulate the natural conditions under which diamonds form deep within the earth, resulting in stones that are genuine diamonds.

Properties of Lab-Created Diamonds

  1. Hardness: Lab-created diamonds score a perfect 10 on the Mohs hardness scale, making them the hardest known natural material. This durability means they are less susceptible to scratches and can maintain their brilliance for a lifetime.
  2. Brilliance and Sparkle: Lab-created diamonds exhibit a brilliance that rivals that of natural diamonds. The unique way they reflect light creates a stunning sparkle that is both captivating and timeless.
  3. Color: Like natural diamonds, lab-created diamonds can come in a range of colors, from colorless to shades of yellow and brown. Their grading adheres to the same standard as natural diamonds, allowing you to choose one that meets your preferences.
  4. Ethical Considerations: One of the most appealing aspects of lab-created diamonds is their ethical sourcing. At DiamondsByUK, we ensure that our lab-grown diamonds are conflict-free and produced with minimal environmental impact, aligning with our commitment to sustainability.
  5. Value: While lab-created diamonds are generally more affordable than natural diamonds, they hold a higher resale value compared to cubic zirconia. They are a wise investment for those seeking genuine beauty without compromising on ethics.

Key Differences Between Cubic Zirconia and Lab-Created Diamonds

Now that we have explored the individual characteristics of cubic zirconia and lab-created diamonds, let's summarize the key differences:

  1. Composition:
    • Cubic Zirconia: Made from zirconium dioxide, lacks carbon.
    • Lab-Created Diamonds: Composed of pure carbon, identical to natural diamonds.
  2. Hardness:
    • Cubic Zirconia: Ranks 8-8.5 on the Mohs scale.
    • Lab-Created Diamonds: Ranks 10 on the Mohs scale.
  3. Brilliance:
    • Cubic Zirconia: Exhibits a rainbow effect, less refined sparkle.
    • Lab-Created Diamonds: Exhibits a subtle brilliance, akin to natural diamonds.
  4. Color Range:
    • Cubic Zirconia: Typically colorless, can be artificially colored.
    • Lab-Created Diamonds: Available in a range of natural colors, graded on the diamond scale.
  5. Value:
    • Cubic Zirconia: Low resale value, inexpensive to produce.
    • Lab-Created Diamonds: Higher resale value, more affordable than natural diamonds.
  6. Ethical Considerations:
    • Cubic Zirconia: No ethical sourcing concerns.
    • Lab-Created Diamonds: Conflict-free and environmentally responsible.
