Cubic Zirconia vs. Diamonds: Unveiling the Truth Behind Fake Diamonds

When it comes to gemstones, diamonds have held an unparalleled allure for centuries. They are renowned for their brilliance, rarity, and timeless beauty. However, in the world of jewelry, there’s another player on the scene that often gets a bad rap – cubic zirconia. Some dismiss it as a mere “fake” diamond, but is that a fair assessment? In this blog post, we will delve into the intricacies of cubic zirconia, exploring its properties, comparing it to diamonds, and shedding light on the debate surrounding these two gemstones.

The Origins of Cubic Zirconia

Cubic zirconia, often abbreviated as CZ, is a synthesized gemstone created from zirconium dioxide. It was first developed in the 1970s as a more affordable alternative to diamonds. CZ quickly gained popularity for its remarkable similarity to diamonds in terms of appearance and brilliance. This likeness, however, has led to the misconception that cubic zirconia is nothing more than a fake diamond.

Composition and Properties

Before we delve into the comparison, let’s understand what cubic zirconia is made of and its inherent properties:

  • Composition: CZ is a lab-created gemstone with a crystal structure that closely resembles that of diamonds. While diamonds are formed deep within the Earth’s mantle over billions of years, cubic zirconia is grown in controlled environments.
  • Brilliance: CZ shares a high level of brilliance with diamonds. Its ability to refract and disperse light creates a dazzling sparkle that’s visually similar to a diamond’s.
  • Durability: Diamonds are the hardest natural substance on Earth, scoring 10 on the Mohs scale of mineral hardness. CZ, while not as hard, is still relatively durable and suitable for everyday wear.

The Comparison

Now, let’s compare cubic zirconia and diamonds across several key aspects:


One of the most significant differences is the price. Diamonds, especially those of high quality and larger carat weights, can be incredibly expensive. In contrast, cubic zirconia is significantly more affordable, making it an attractive option for those on a budget.


Diamonds are rare and precious gems, which contributes to their high cost. Cubic zirconia, being man-made, is readily available, making it a more accessible choice.

Ethical Considerations

Diamond mining has been associated with ethical concerns, including environmental damage and conflict diamonds. Cubic zirconia, being synthetic, doesn’t have these same ethical implications.


While cubic zirconia can match the brilliance of diamonds, it may lack the depth and complexity in its sparkle that natural diamonds exhibit.


Diamonds are exceptionally hard and scratch-resistant. Cubic zirconia is less hard but still durable enough for everyday wear. It may require more care to avoid scratches.

The Verdict

So, is cubic zirconia a fake diamond? The answer isn’t a simple yes or no. CZ may not be a natural diamond, but it offers a valid and affordable alternative for those who appreciate its beauty and value. It’s essential to consider your budget, ethical concerns, and personal preferences when choosing between cubic zirconia and diamonds. Ultimately, both have their merits, and the choice depends on what matters most to you as a jewelry enthusiast.
