Moissanite vs Cubic Zirconia: What’s the Difference?

With rising diamond costs, many couples consider affordable alternatives like moissanite and cubic zirconia for engagement rings. While they resemble diamonds, moissanite and CZ have distinct chemical properties influencing their durability, brilliance, and value. Understanding their differences enables selecting the right stone.

Originating from meteors, moissanite diamond is made of silicon carbide. Its lab creation process accurately reproduces moissanite’s natural structure. At 9.25 on the Mohs scale, moissanite exceeds traditional diamonds in hardness and brilliance. Its impressive refractive index produces exceptional fire.

Meanwhile, cubic zirconia is made of zirconium oxide powder liquefied at high temperatures. Its manufacturing process leaves structural flaws making CZ softer at 8 on the Mohs scale. CZ has an excellent brilliance but lower refractive index than moissanite.

In terms of appearance, both mimic a diamond’s dazzle. Well-cut moissanite actually exceeds a diamond’s brilliance. But moissanite projects slightly warmer tones from its hints of yellow and green hue. High quality CZ looks ice-white when newly polished but loses luster over time.

For durability, moissanite diamond outperforms CZ. Harder than ruby or sapphire, moissanite resists scratching or clouding. CZ’s softer structure makes it prone to abrading and dulling over years of wear. Moissanite’s resilience assures its sparkle will endure.

Lastly, moissanite costs substantially less than diamonds due to availability. But rarer than CZ, moissanite commands a higher price for its unmatched brilliance and durability. Overall, CZ offers short-term savings while moissanite provides lasting beauty and value.

With higher hardness, brilliance and endurance than CZ, moissanite diamond rivals diamonds at lower costs. Couples desiring resilience and dazzle find an ideal alternative in moissanite. For budget-friendly sparkle, CZ works but requires replacement over time. Let your priorities guide the perfect choice!
