An Introduction to Cubic Zirconia

An Introduction to Cubic Zirconia

Cubic Zirconia, often abbreviated as CZ, is a synthetic gemstone that has gained immense popularity as a diamond alternative over the years. Known for its brilliant sparkle and affordability, CZ has become a preferred choice for many jewelry enthusiasts.

What Is Cubic Zirconia?

Cubic Zirconia is a synthetic gemstone and is the cubic crystalline form of zirconium dioxide (ZrO2).

How Is Cubic Zirconia Created?

Cubic zirconia is created by melting zirconium oxide in a metal chamber and then incorporating minerals such as calcium and magnesium. After that, it is heated to 4982 Fahrenheit (2750 Celsius). Crystals begin to form once it is cooled. The stone is then cut into various shapes. Skilled artisans then polish the gem to enhance its brilliance and sparkle.

Key Characteristics


Cubic zirconia resembles a diamond in its appearance, with its brilliant, colorless clarity. It can also be cut into various shapes, including round, princess, emerald, and more.


Cubic Zirconia is renowned for its high refractive index, which contributes to its impressive brilliance. It disperses light in a way that creates a dazzling play of colors, similar to that of a diamond.


While cubic zirconia is quite hard, it is not as durable as a natural diamond. It ranks at 8-8.5 on the Mohs scale of hardness.


Cubic Zirconia is a cost-effective alternative to diamonds, allowing individuals to enjoy the look of luxury without the hefty price tag.

Color Variations:

While most Cubic Zirconia is colorless, it can be produced in various colors by adding specific dopants during the manufacturing process. This makes it versatile for use in a wide range of jewelry designs.

Cubic Zirconia, with its remarkable brilliance, affordability, and versatility, has established itself as a popular alternative to natural diamonds in the world of jewelry. While it may not possess the same durability as a diamond, it offers an accessible means of adding sparkle and luxury to any jewelry collection.

Whether you're looking for an engagement ring, a fashion accessory, or a custom-made piece, cubic zirconia provides a dazzling and budget-friendly option. Learn how to choose cubic zirconia jewelry with Eleganzia Jewelry.
