Ultimate Guide: Cubic Zirconia vs Moissanite – Which is the Better Choice?
When it comes to choosing the perfect gemstone for your jewelry, the options can be overwhelming. Two popular alternatives to diamonds are cubic zirconia (CZ) and moissanite. Both offer stunning beauty at a fraction of the cost of diamonds, but which one is the better choice for you? In this ultimate guide, we’ll compare cubic zirconia and moissanite in terms of appearance, durability, cost, and more to help you make an informed decision.
First, let's take a closer look at cubic zirconia. Often abbreviated as CZ, cubic zirconia is a synthetic gemstone made from zirconium dioxide. It first gained popularity in the jewelry market in the late 1970s as an affordable diamond substitute. Cubic zirconia is celebrated for its high refractive index, which gives it a brilliant sparkle that’s comparable to real diamonds. Additionally, it’s quite affordable, making it a popular choice for those on a budget.
On the other hand, moissanite is a naturally occurring mineral discovered by French chemist Henri Moissan in 1893. Originally found in meteorites, natural moissanite is extremely rare, so most moissanite used in jewelry today is lab-created. Moissanite is prized for its exceptional fire, which refers to the rainbow-colored flashes of light that it emits, even surpassing that of a diamond. Its durability and brilliance have made it a favorite among those seeking an ethical and budget-friendly alternative to diamonds.
One of the main reasons people choose gemstones like cubic zirconia and moissanite is their brilliance—how much they sparkle under light. Cubic zirconia has a refractive index ranging from 2.15 to 2.18, which gives it a notable level of brilliance. However, moissanite surpasses it with a refractive index of 2.65 to 2.69. This means that moissanite reflects more light and often appears more dazzling than cubic zirconia.
When it comes to fire, cubic zirconia exhibits less dispersion, which means its flashes of colored light are subtler. Moissanite, on the other hand, has a dispersion rating of 0.104, significantly higher than that of cubic zirconia (0.058), resulting in a more vivid and noticeable rainbow effect. This makes moissanite particularly appealing to those who are looking for a gemstone that stands out in any light situation.
Appearance
Cubic Zirconia
Cubic zirconia is known for its brilliant sparkle and clear, colorless appearance. It is often compared to a flawless diamond due to its high level of brilliance and fire. However, CZ can sometimes appear too perfect, almost artificial, due to its lack of inclusions and color variations that are typically found in natural diamonds.
Moissanite
Moissanite, on the other hand, has a unique brilliance and fire that often surpasses that of a diamond. It displays a rainbow-like effect when exposed to light, known as "dispersion," which gives it a more vibrant appearance. Moissanite also comes in near-colorless to slightly yellowish tones, which can mimic the color range of natural diamonds more closely.
Durability
Cubic Zirconia
Cubic zirconia is a relatively soft gemstone, ranking 8.0-8.5 on the Mohs scale of hardness. This makes it more susceptible to scratches and abrasions over time, which can diminish its sparkle and clarity.
Moissanite
Moissanite is significantly harder, ranking 9.25 on the Mohs scale. This hardness makes it highly resistant to scratches and suitable for everyday wear. Moissanite's durability ensures that it maintains its brilliance and beauty for a long time, making it a practical choice for engagement rings and other frequently worn jewelry.
Appearance
Cubic Zirconia
One of the biggest advantages of cubic zirconia is its affordability. CZ is significantly cheaper than both diamonds and moissanite, making it an attractive option for those on a tight budget. You can get a larger, more dazzling stone for a fraction of the price of a diamond.
Moissanite
While more expensive than cubic zirconia, moissanite is still much more affordable than diamonds. The cost of moissanite varies depending on its size and quality, but it generally offers a good balance between cost and quality. For those looking for a long-lasting and brilliant gemstone without breaking the bank, moissanite is an excellent choice.
Clarity and Color
Cubic Zirconia
Cubic zirconia is typically flawless, with no visible inclusions or blemishes. It is also available in a variety of colors, allowing for more customization in jewelry design. However, the lack of inclusions can sometimes make CZ appear less natural compared to diamonds.
Moissanite
Moissanite usually has fewer inclusions than diamonds, and those that do exist are often only visible under magnification. Moissanite also comes in near-colorless grades, similar to high-quality diamonds, though it can have a slightly warmer tone. This slight color variation can enhance its natural appearance.
Environmental and Ethical Considerations
Cubic Zirconia
Cubic zirconia is a lab-created gemstone, which means its production has a minimal environmental impact compared to mining natural diamonds. This makes it an ethical and eco-friendly choice for those concerned about the environmental and social issues associated with diamond mining.
Moissanite
Like cubic zirconia, moissanite is also lab-created. This ensures that its production is free from the ethical concerns linked to diamond mining, such as exploitation and conflict. Choosing moissanite supports sustainable and responsible jewelry practices.
Appearance
Heat Resistance
Cubic Zirconia
Cubic zirconia is not very heat resistant and can be damaged by high temperatures. It’s important to remove CZ jewelry when exposed to heat sources, such as during cooking or using hair styling tools.
Moissanite
Moissanite has excellent heat resistance and can withstand high temperatures without damage. This makes it a more practical choice for those who frequently expose their jewelry to heat.
Weight
Cubic Zirconia
Cubic zirconia is denser than moissanite, which means that a CZ stone of the same size as a moissanite stone will be heavier. This can sometimes affect the overall feel of the jewelry.
Moissanite
Moissanite is lighter in weight compared to cubic zirconia. This can make moissanite jewelry more comfortable to wear, especially for larger pieces.
Refractive Index
Cubic Zirconia
Cubic zirconia has a lower refractive index compared to moissanite, which means it reflects less light and has less brilliance. While still dazzling, it doesn’t quite match the sparkle of moissanite.
Moissanite
Moissanite has a higher refractive index than both cubic zirconia and diamonds, which gives it superior brilliance and fire. Its exceptional sparkle is one of the key reasons why many people choose moissanite over other gemstones.
Conclusion: Which is the Better Choice?
Ultimately, the choice between cubic zirconia and moissanite depends on your personal preferences and priorities.
Choose Cubic Zirconia if:
- You are on a tight budget and want an affordable, yet beautiful gemstone.
