Moissanite vs Cubic Zirconia: Which is the Best Affordable Diamond Alternative?

When choosing an engagement ring or another piece of jewelry, many people consider alternatives to diamonds. Moissanite and cubic zirconia (CZ) are two popular options.

Cubic zirconia (CZ) is a diamond simulant that is completely colorless, providing a bright but artificial appearance. Moissanite, however, is created through a complex process, resulting in a gemstone with a chemical composition closer to natural diamonds. Additionally, moissanite has greater hardness and brilliance, making it a more durable and sparkling choice compared to cubic zirconia.

Let's explore the moissanite vs cubic zirconia characteristics in detail to help you make the best choice for your bling game.

 

Composition and Eco-Friendly Considerations

Moissanite is made of silicon carbide and was first discovered in a meteorite crater. This naturally occurring mineral is rare, so moissanite used in jewelry is typically lab-created. This is often considered a more eco-friendly choice compared to mined diamonds.

Similarly, cubic zirconia is also lab-grown, usually from zirconium dioxide, making it another eco-friendly option.

The production of both of these diamond alternatives avoids the detrimental environmental and ethical issues related to diamond mining, making it a popular choice for environmentally conscious consumers.

 

Brilliance and Fire

Moissanite is known for its exceptional brilliance and fire that rivals that of diamonds, making it a showstopper wherever you go. Moissanite often exhibits rainbow-like flashes of color, and its superior refractive index (higher than diamonds) gives it a unique sparkle that sets it apart from other gemstones.

Cubic zirconia tends to have a more uniform sparkle compared to moissanite. While it can mimic the appearance of diamonds to some degree, its brilliance may appear slightly different due to its lower refractive index.

 

Color Variation

High-quality moissanite and cubic zirconia are often chosen for their colorless appearance, closely resembling that of colorless diamonds. However, there can be subtle differences in color between the two, which might influence your decision based on personal preference.

Over time, cubic zirconia can absorb oils and chemicals, which may cause it to develop a slight yellowish or cloudy appearance. This color change can be mitigated with proper care and cleaning but is something to consider for long-term wear.

 

Durability and Longevity

Let’s say you’re wearing your favorite moissanite ring, and you accidentally bump it against a hard surface. No need to panic! Moissanite stones are extremely tough, ranking 9.25 on the Mohs hardness scale, just below diamonds which rank at 10. That means it can handle most situations, from everyday wear to spontaneous adventures.

Cubic zirconia, on the other hand, is a bit more delicate, ranking around 8 on the Mohs hardness scale. That's not to say you can't wear a cubic zirconia ring out in public or while running errands, but it's important to handle it with care to avoid any scratches or chips.

 

Affordability and Value

One of the biggest advantages of moissanite is it offers exceptional value for its price, providing the look of a diamond at a fraction of the cost. You can snag yourself stunning moissanite jewelry without draining your savings account. Talk about a win-win!

Cubic zirconia is also known for its budget-friendly nature. Just keep in mind that while cubic zirconia can be even more affordable upfront, it may not hold its value as well as moissanite in the long run.

 

Can It Pass the Diamond Test?

Moissanite gemstones can often pass a diamond test due to their similarity in optical and physical properties to diamonds. Moissanite exhibits similar thermal and electrical conductivity to that of diamonds. Hence, some traditional diamond testers, which rely on these two elements, may identify moissanite as diamonds due to their similar properties.

Cubic zirconia, on the other hand, has very different properties compared to diamonds and generally will not pass a diamond tester.

 

Conclusion

Ultimately, the decision between moissanite and cubic zirconia hinges on personal preferences and budget constraints. Those who prioritize durability, brilliance, and a closer resemblance to diamonds are likely to favor moissanite. On the other hand, those in search of a budget-friendly and easily accessible alternative may opt for cubic zirconia.
