If you’re shopping for gemstones, the price difference between a diamond and a cubic zirconia can be staggering. A 1-carat diamond typically costs anywhere from $2,000 to over $10,000, depending on its quality . In contrast, a 1-carat cubic zirconia stone is worth only about $10 to $30 on average for the loose stone itself .

This enormous gap in price is the main reason cubic zirconia has become such a popular and accessible alternative to diamonds .

Why Is Cubic Zirconia So Inexpensive?

The low price of cubic zirconia comes down to two main factors:

It’s Lab-Created: Unlike diamonds, which take millions of years to form deep underground and require expensive mining, cubic zirconia is a synthetic gemstone created in a laboratory. It can be produced quickly and in massive quantities, which keeps costs extremely low . In fact, annual global production of cubic zirconia has reached hundreds of tonnes .
It’s a Simulant: Cubic zirconia is a “diamond simulant,” meaning it looks like a diamond but is made of entirely different material (zirconium dioxide). It does not have the rarity, tradition, or resale value of a natural diamond, which is reflected in its price .

What Factors Affect the Price of Cubic Zirconia?

While a 1-carat cubic zirconia is very affordable, its price can still vary based on a few factors :

Quality: Higher-grade stones with better clarity and color consistency will cost slightly more than lower grades. Premium 5A-grade cubic zirconia typically costs a bit more than standard commercial-grade stones.
Cut: Stones with precision cutting that enhances brilliance and sparkle may have a slightly higher price.
Setting: While the cubic zirconia stone itself is cheap, the setting—such as sterling silver, gold, or platinum—can significantly raise the overall cost of the jewelry. A 1-carat CZ ring in sterling silver might sell for around $40-$90, while a solid gold setting would be much more expensive .

Factor	Diamond	Cubic Zirconia
Typical 1 Carat Cost	$2,000–$10,000+	$10–$30
Composition	Pure Carbon	Zirconium Dioxide (ZrO₂)
Hardness (Mohs)	10 (hardest)	8–8.5
Resale Value	Retains value over time	Virtually no resale value

The Big Picture: Value vs. Cost

The “worth” of a 1-carat cubic zirconia is not in its resale value, which is virtually nonexistent. Instead, its value is in its beauty and affordability. For a very modest budget, you can own a stunning piece of jewelry that closely mimics the look of a diamond. It is an excellent choice for fashion-forward jewelry, travel pieces, or as a temporary ring .
