Moissanite vs. Cubic Zirconia: What's the Difference?
Both moissanite and cubic zirconia (CZ) offer beautiful sparkle, but they are different materials with different properties, durability, and price points. Understanding these differences can help you choose the right jewelry for your lifestyle and budget.
At The Raz Co., we believe that informed shoppers make confident choices. Let's explore what sets these two popular jewelry stones apart.
What Is Cubic Zirconia?
Cubic zirconia is a man-made crystalline material made from zirconium dioxide. It is widely used in jewelry as an affordable alternative to other sparkling gemstones.
CZ can be cut to produce impressive brilliance and a bright, clear appearance. Its affordability makes it a popular choice for fashion jewelry, special occasions, and shoppers who enjoy changing their look without a large investment.
Cubic zirconia has a hardness of approximately 8.5 on the Mohs scale. Although reasonably durable, it is softer than moissanite and may be more susceptible to scratches and surface wear over time.
What Does AAA Cubic Zirconia Mean?
You may see cubic zirconia advertised as AAA, AAAAA, or with other letter-based grades.
These labels are commonly used as commercial quality descriptions, but there is no single universal grading system that makes every seller's AAA designation equivalent.
The label alone does not guarantee a particular level of brilliance, durability, or long-term performance. Cut quality, clarity, color, finishing, and the manufacturer's specifications are more useful factors to consider.
What Is Moissanite?
Moissanite is a gemstone material made from silicon carbide. Natural moissanite is exceptionally rare, so moissanite used in contemporary jewelry is generally laboratory-created.
Moissanite is known for its brilliance and distinctive flashes of rainbow-colored light, a property called fire. Depending on the cut, lighting, and stone size, this colorful sparkle may be more noticeable than it is in other clear gemstones.
Moissanite has a hardness of approximately 9.25 on the Mohs scale, making it harder than cubic zirconia and well suited to jewelry intended for frequent wear.
Its combination of sparkle, durability, and relatively low maintenance makes it a popular choice for engagement rings, everyday rings, and other jewelry pieces.
Moissanite vs. Cubic Zirconia: At a Glance
Cubic Zirconia (CZ)
- Composition: Zirconium dioxide.
- Hardness: Approximately 8.5 on the Mohs scale.
- Appearance: Bright brilliance with a clear, gemstone-like look.
- Durability: Good for many jewelry uses, although scratches and surface wear can accumulate.
- Price: Generally the more budget-friendly option.
- Ideal for: Fashion jewelry, occasional wear, and affordable sparkling styles.
Moissanite
- Composition: Silicon carbide.
- Hardness: Approximately 9.25 on the Mohs scale.
- Appearance: Strong brilliance with pronounced rainbow-colored fire.
- Durability: Excellent resistance to scratching and suitable for frequent wear.
- Price: Generally more expensive than CZ, but often accessible compared with other precious gemstone options.
- Ideal for: Everyday jewelry and shoppers seeking long-lasting sparkle.
Which Stone Sparkles More?
Both materials can be beautifully brilliant, but their sparkle looks different.
Cubic zirconia can produce a bright, attractive appearance, especially when well cut.
Moissanite has strong brilliance and a higher dispersion of light, meaning it can display more pronounced rainbow-colored flashes. Some people love this dramatic fire, while others prefer the appearance of CZ.
Neither appearance is automatically better for everyone. Your personal preference, the stone's cut, its size, and the lighting all influence what you see.
Does Cubic Zirconia Turn Yellow Over Time?
This is a common question.
Cubic zirconia does not inevitably turn yellow simply because it ages. However, lower-quality material, surface wear, accumulated residue, and exposure to products or environmental conditions can affect its appearance. Scratches and loss of polish can also make a stone look less bright.
Moissanite is highly durable and generally maintains its optical appearance well with appropriate care. However, its original color grade matters, and some stones can have a slight yellowish or grayish tint depending on their quality.
The important distinction is that moissanite is harder and more resistant to scratching than CZ. Neither material is completely immune to damage, dirt, or changes in appearance caused by its setting and care.
Which Stone Is Better for Everyday Wear?
If you intend to wear a ring frequently, durability is an important consideration.
Moissanite's greater hardness makes it more resistant to scratching, and its durability is one reason it is popular for everyday rings.
Cubic zirconia can still be a lovely choice, particularly for fashion jewelry or pieces worn occasionally. With reasonable care, CZ jewelry can provide plenty of enjoyment.
When choosing either material, consider the quality of the setting as well as the stone. Prongs, mountings, and overall craftsmanship affect how securely a gemstone is held.
Which Stone Should You Choose?
Choose cubic zirconia if you want an affordable, sparkling option and enjoy having a variety of jewelry styles.
Consider moissanite if you prefer pronounced rainbow fire, excellent scratch resistance, and a stone suited to frequent wear.
The right choice depends on your budget, taste, and how you plan to wear the piece.
Always review the individual product description to confirm the gemstone material and any available specifications. Terms such as AAA should not replace clear material information.
