Cubic Zirconia: The Affordable Diamond Simulant
Cubic zirconia, also known as CZ, is a synthetic material that has been used as a diamond simulant for decades. It is made of zirconium oxide (ZrO2) and has a similar appearance to diamond, with a high refractive index and a brilliant sparkle. CZ is much more affordable than diamond, making it a popular choice for jewelry and other applications.
Properties of Cubic Zirconia
- Hardness: CZ is a very hard material, with a Mohs hardness of 8.5. This makes it resistant to scratches and abrasions, making it suitable for use in jewelry.
- Refractive index: CZ has a high refractive index of 2.15, which is close to that of diamond (2.42). This means that CZ can reflect light in a similar way to diamond, creating a brilliant sparkle.
- Fire: CZ exhibits a high level of fire, which is the amount of light that is dispersed into colors. This gives CZ a similar level of brilliance to diamond.
Advantages of Cubic Zirconia
- Affordability: CZ is much more affordable than diamond, making it a great option for those who want the look of diamond without the high price tag.
- Durability: CZ is a very durable material that is resistant to scratches and abrasions, making it suitable for everyday wear.
- Versatility: CZ can be cut and shaped into a variety of shapes and sizes, making it suitable for use in a wide range of jewelry applications, including rings, necklaces, earrings, and bracelets.
Disadvantages of Cubic Zirconia
- Not as hard as diamond: CZ is not as hard as diamond, so it can be scratched more easily. However, it is still a very durable material for everyday wear.
- Not as brilliant as diamond: CZ has a slightly lower refractive index than diamond, so it does not reflect light as brilliantly. However, it still has a high level of fire, giving it a similar level of brilliance to diamond.
Applications of Cubic Zirconia
CZ is used in a wide range of applications, including:
- Jewelry: CZ is a popular choice for jewelry, as it is affordable and durable. It is often used in engagement rings, wedding bands, and other fine jewelry.
- Industrial: CZ is also used in a variety of industrial applications, such as cutting tools, bearings, and windows.
- Medical: CZ is used in some medical applications, such as dental implants and surgical instruments.

Tips and Tricks for Choosing Cubic Zirconia
When choosing cubic zirconia, there are a few things to keep in mind:
- Cut: The cut of a CZ will affect its brilliance and sparkle. A well-cut CZ will have a high level of fire and will reflect light in a similar way to diamond.
- Clarity: The clarity of a CZ will affect its appearance. A clear CZ will have no visible inclusions or blemishes.
- Color: CZ is available in a variety of colors, including colorless, yellow, pink, and blue. The color of a CZ will depend on the impurities present in the material.
Common Mistakes to Avoid
When buying cubic zirconia, there are a few common mistakes to avoid:
- Buying a CZ that is too small: A CZ that is too small will not have the same level of brilliance and sparkle as a larger stone.
- Buying a CZ that is cloudy or has inclusions: A clear CZ will have no visible inclusions or blemishes.
- Buying a CZ that is not well-cut: A poorly cut CZ will not reflect light in the same way as a well-cut stone.
