Moissanite vs. Cubic Zirconia

Moissanite vs. Cubic Zirconia: The Ultimate Comparison for the Conscious Jewelry Shopper

When it comes to choosing an affordable and beautiful alternative to diamonds, both moissanite and cubic zirconia (CZ) are popular choices. But how do they compare? In this article, we'll explore the similarities and differences between moissanite and cubic zirconia, discussing their properties, appearance, and overall value, to help you make the right choice for your next jewelry purchase.

Properties and Composition

Moissanite, a lab-grown gemstone with a crystalline structure similar to that of a diamond, is known for its remarkable brilliance, fire, and durability. On the Mohs scale of hardness, moissanite ranks at 9.25, making it an excellent choice for everyday wear. It also boasts impressive fire and brilliance, often surpassing that of a diamond.

Cubic zirconia, on the other hand, is a synthesized material made from zirconium dioxide. With a Mohs hardness of 8 to 8.5, CZ is relatively durable, but not as hard as moissanite or diamond. Its fire and brilliance are also lower than that of moissanite, with a tendency to exhibit more "rainbow effect" when exposed to light.

Appearance and Value

While both moissanite and cubic zirconia are beautiful in their own right, moissanite is often considered the more visually appealing and valuable choice. Its superior hardness, brilliance, and fire make it an excellent diamond alternative that can easily withstand daily wear. Additionally, moissanite is available in a variety of cuts and styles, ensuring that you can find the perfect piece for your taste.

Cubic zirconia, although less expensive than moissanite, may not offer the same long-lasting beauty and durability. Over time, CZ stones may become scratched or cloudy, requiring replacement. However, their affordability makes them a popular choice for those seeking a temporary or budget-friendly option.

When comparing moissanite and cubic zirconia, moissanite emerges as the superior choice for those seeking a durable, brilliant, and valuable diamond alternative. While cubic zirconia may be a more budget-friendly option, its lower hardness and brilliance make it less desirable for long-term wear.
