Is a Lab Created Diamond the Same as Cubic Zirconia?

Introduction

Can true luxury also be truly ethical? As conscientious consumerism rises in popularity, more individuals are seeking luxury items that align with their values. In the realm of fine jewellery, this quest often leads to the question: Is a lab created diamond the same as cubic zirconia?

Both lab created diamonds and cubic zirconia (CZ) have emerged as popular alternatives to natural diamonds. However, these two gemstones differ significantly in origin, composition, and value. With the world increasingly focused on sustainability and ethical sourcing, understanding the distinctions between these two options is vital for anyone looking to invest in fine jewellery.

At DiamondsByUK, we are committed to redefining luxury by offering sustainable, conflict-free diamond jewellery that is accessible to all. Our dedication to craftsmanship, integrity, and customer-focused service sets us apart.

So, are you dreaming of a piece of jewellery that’s as unique as your story? By the end of this post, you will be well-equipped to make an informed decision that reflects your personal values and style.

Let’s dive into the world of lab grown diamonds and cubic zirconia, uncovering what makes each one special.

Understanding Lab Created Diamonds

What Are Lab Created Diamonds?

Lab created diamonds, also known as synthetic or man-made diamonds, are real diamonds that are created in controlled environments using advanced technology. The process simulates the natural conditions under which diamonds form deep within the Earth, thus producing stones that share the same chemical, physical, and optical properties as natural diamonds.

There are two primary methods for creating lab grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both techniques utilize carbon sources to produce diamonds, but they differ in their approach:

HPHT: This method replicates the extreme heat and pressure found in the Earth’s mantle. It involves placing a carbon source along with a diamond seed in a high-pressure chamber, where conditions are manipulated to form diamonds over a period of weeks.
CVD: In this method, a carbon-rich gas is introduced into a chamber, where it is ionized to create a plasma. This plasma allows carbon atoms to deposit onto a diamond seed, gradually forming a diamond crystal.

Lab created diamonds are graded using the same standards as natural diamonds—color, cut, clarity, and carat weight (the 4Cs). At DiamondsByUK, we specialize in IGI-certified lab grown diamonds, ensuring that every piece we offer meets the highest standards of quality and ethics.

The Benefits of Lab Created Diamonds

Ethical Sourcing: Lab created diamonds are 100% conflict-free, meaning they are produced without the ethical dilemmas often associated with mined diamonds. This aligns with our values at DiamondsByUK, as we prioritize sustainability and integrity in every piece we create.
Cost-Effectiveness: Lab created diamonds typically cost 20-40% less than their natural counterparts. This affordability allows you to invest in a larger carat or higher quality without compromising your budget.
Customization: At DiamondsByUK, we offer full customization for our lab grown diamonds, allowing you to create a piece that is truly unique. From engagement rings to bracelets, almost any design can be tailored to your specifications, often with a turnaround time of just 1-2 weeks.
Durability: Lab grown diamonds rank a perfect 10 on the Mohs hardness scale, meaning they are incredibly durable and resistant to scratches. This makes them ideal for everyday wear, especially in engagement and wedding rings.
Environmental Impact: The production of lab created diamonds has a significantly lower environmental footprint compared to mined diamonds. By choosing lab grown options, you contribute to a more sustainable future.

The Allure of Lab Created Diamonds

Lab created diamonds are not just an ethical choice; they are also stunning and visually comparable to natural diamonds. They possess the same brilliance and fire, catching the light beautifully and reflecting it in a way that makes them captivating. Whether you prefer a classic round cut or a trendy pear shape, lab grown diamonds can be crafted to suit any style.

Understanding Cubic Zirconia

What is Cubic Zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that is often used as a diamond simulant. Unlike lab created diamonds, which are real diamonds made of carbon, cubic zirconia is composed of zirconium dioxide. This means that while CZ can mimic the appearance of a diamond, it does not share the same chemical or physical properties.

Cubic zirconia is produced by melting zirconium oxide powder with stabilizers, such as calcium and magnesium, at extremely high temperatures. As it cools, the material crystallizes, resulting in a brilliant, colorless gemstone that can be cut and polished to resemble a diamond.

The Appeal of Cubic Zirconia

Affordability: One of the most significant advantages of cubic zirconia is its low cost. CZ can be produced at a fraction of the price of lab grown diamonds, making it an attractive option for budget-conscious shoppers.
Brilliance and Clarity: Cubic zirconia is known for its exceptional clarity and brilliance. It is virtually flawless and can be manufactured in various colors, giving consumers the option to choose from a wide range of hues.
Light Dispersion: CZ has a higher dispersion rate than diamonds, which means it can exhibit more colorful flashes of light. This can create a striking visual effect, although it may not be as subtle or sophisticated as the sparkle of a diamond.

Limitations of Cubic Zirconia

While cubic zirconia has its benefits, it also has notable limitations compared to lab created diamonds:

Durability: Cubic zirconia ranks between 8 and 8.5 on the Mohs hardness scale, making it less durable than lab created diamonds. This means it is more susceptible to scratches and can become cloudy over time.
Resale Value: Unlike lab created diamonds, which can retain some value, cubic zirconia has little to no resale value. It is considered a cost-effective option for those who want the look of a diamond without the investment.
Synthetic Nature: While cubic zirconia can be beautiful, it lacks the inherent qualities that make diamonds so desirable. For many, the allure of a diamond lies in its natural origin, rarity, and the emotional significance associated with it.

Comparing Lab Created Diamonds and Cubic Zirconia

Chemical Composition

Lab Created Diamonds: Composed of carbon, lab created diamonds share the same chemical structure as natural diamonds. They are graded using the same standards and exhibit the same optical properties.
Cubic Zirconia: Made from zirconium dioxide, CZ does not possess the same chemical composition as diamonds, making it a different material entirely.

Hardness and Durability

Lab Created Diamonds: With a hardness of 10 on the Mohs scale, lab created diamonds are extremely durable and resistant to scratches.
Cubic Zirconia: Ranging from 8 to 8.5 on the Mohs scale, CZ is less durable and can show signs of wear more quickly than diamonds.

Appearance and Brilliance

Lab Created Diamonds: Lab created diamonds exhibit a brilliant sparkle and fire, similar to that of natural diamonds. Their appearance can vary based on cut, color, and clarity.
Cubic Zirconia: While CZ can appear bright and clear, its higher dispersion can create a rainbow effect that some may find less appealing than a diamond's understated brilliance.

Cost

Lab Created Diamonds: Typically priced 20-40% lower than natural diamonds, lab created diamonds offer an ethical and cost-effective alternative without sacrificing quality.
Cubic Zirconia: CZ is significantly cheaper than both lab created and natural diamonds, making it an accessible option for those on a tight budget.

Resale Value

Lab Created Diamonds: These diamonds can retain value, especially if they are of high quality and certified. They can be resold or repurposed, making them a more sustainable choice.
Cubic Zirconia: CZ has little to no resale value, as it is viewed as an inexpensive alternative rather than a valuable gemstone.

Should You Choose a Lab Created Diamond or Cubic Zirconia?

Choosing between a lab created diamond and cubic zirconia ultimately depends on your values and priorities. If you are looking for a sustainable, ethical, and durable option that retains value, lab created diamonds are the superior choice. They offer the beauty and brilliance of natural diamonds without the environmental impact or ethical concerns associated with mining.

On the other hand, if you are on a strict budget or prefer a gemstone that allows for more colorful options, cubic zirconia may be suitable for you. It provides an eye-catching appearance at a significantly lower price point.
