What Is Cubic Zirconia?

Cubic zirconia, often referred to as CZ, is a high-quality, man-made gemstone created to closely resemble the appearance of a diamond. Known for its exceptional clarity, brilliance and affordability, cubic zirconia has become one of the most popular diamond alternatives in modern jewellery.

At Clarindon Jewellers, cubic zirconia is valued for its versatility, visual impact and suitability for contemporary and fashion-forward jewellery designs.


How Is Cubic Zirconia Made?

Cubic zirconia is a synthetic gemstone, produced in a laboratory under carefully controlled conditions. It is made from zirconium dioxide and crystallised to create a stone with excellent optical properties.

Unlike natural gemstones, cubic zirconia:

  • Is entirely man-made

  • Has no natural inclusions

  • Can be produced in consistent quality

This allows for exceptional clarity and uniformity in jewellery.


Cubic Zirconia Appearance & Characteristics

Cubic zirconia is admired for its:

  • Bright white appearance

  • High brilliance and sparkle

  • Flawless clarity

Key properties include:

  • Mohs hardness: 8–8.5

  • Higher dispersion than diamond, creating strong flashes of colour

  • Heavier weight than diamond of the same size

While visually similar to diamond, cubic zirconia has distinct physical differences.


Cubic Zirconia vs Diamond

Although cubic zirconia and diamond may look similar at first glance, there are important differences:

Feature Cubic Zirconia Diamond
Origin Man-made Natural
Hardness 8–8.5 10
Weight Heavier Lighter
Brilliance Very high Exceptional
Price Affordable Premium

Cubic zirconia is ideal for those who want the look of a diamond without the cost.


Cubic Zirconia Colours

In addition to classic white, cubic zirconia can be created in a wide range of colours, including:

  • Yellow

  • Blue

  • Pink

  • Green

  • Lavender

This makes cubic zirconia highly versatile for creative and contemporary jewellery designs.

How Cubic Zirconia Is Used

Cubic zirconia is widely used in:

  • Rings and statement rings

  • Earrings and studs

  • Necklaces and pendants

  • Fashion and bridal-style jewellery

Because of its clarity and sparkle, cubic zirconia is often used in pavé settings and multi-stone designs.

It pairs beautifully with sterling silver, gold and plated metals.


Caring for Cubic Zirconia Jewellery

While durable, cubic zirconia benefits from proper care:

  • Clean with warm water and mild soap

  • Avoid harsh chemicals and ultrasonic cleaners

  • Store separately to prevent scratching

  • Remove jewellery during heavy physical activity

Over time, cubic zirconia may lose some surface brilliance if not properly cared for.


Why Choose Cubic Zirconia Jewellery?

Cubic zirconia is prized for its:

  • Diamond-like appearance

  • Excellent clarity and brilliance

  • Affordability

  • Wide design versatility

It is a popular choice for fashion jewellery, travel jewellery and statement pieces.
