Are Lab Grown Diamonds Cubic Zirconia?

Hello there, and welcome to another enlightening blog post from your friends at Acredo. Today, we're going to bust a myth and answer a question that has puzzled many of our customers: "Are lab-grown diamonds the same as cubic zirconia?" Without further ado, let's dive into the world of these captivating gemstones.

Understanding Lab-Grown Diamonds

At Acredo, we offer an array of unique jewelry, including pieces adorned with lab-grown diamonds. These gemstones are created in a laboratory using high-temperature, high-pressure (HTHP), or chemical vapor deposition (CVD) methods, which mirror the natural process that forms diamonds deep within the Earth. 

Lab-grown diamonds have the same physical, chemical, and optical properties as their natural counterparts, making them an ethical and sustainable alternative to mined diamonds.

Deciphering Cubic Zirconia

Cubic zirconia, another popular choice for our handcrafted jewelry, is made in a laboratory too but through a completely different process. It's created by melting powdered zirconium and zirconium dioxide together at incredibly high temperatures to form a brilliantly sparkling stone. 

While cubic zirconia is more affordable and doesn't have the same hardness or refractive index as diamonds, it's an attractive option for those seeking dazzling, budget-friendly jewelry.

Lab-Grown Diamonds vs. Cubic Zirconia

When it comes to lab-grown diamonds and cubic zirconia, they may seem similar at first glance, but their differences become evident under closer inspection. From a hardness perspective, lab-grown diamonds are top of the scale, just like their natural counterparts. Cubic zirconia, while still durable, doesn't match the hardness of a diamond.

In terms of visual appeal, both lab-grown diamonds and cubic zirconia offer a beautiful sparkle. However, a diamond's fire, or the display of spectral colors, is incomparable, even in a lab-grown gem.

Common Misconceptions

Let's clear this up: lab-grown diamonds are not cubic zirconia. These two stones have different physical and optical properties, and they are made using distinct processes. However, they both offer excellent options for creating custom-designed jewelry at Acredo.

Identifying Lab-Grown Diamonds and Cubic Zirconia

Discerning between a lab-grown diamond and cubic zirconia isn't always easy for the untrained eye. But don't worry, at Acredo, we're here to guide you. Whether it's through a personalized consultation or providing certification of authenticity, our aim is to make your jewelry selection experience as easy and enjoyable as possible.


In a nutshell, lab-grown diamonds and cubic zirconia are distinctly different stones offering their unique charm.
