Does Cubic Zirconia Turn Green? The Truth Behind the Sparkle
In the world of affordable luxury, cubic zirconia (CZ) has long been a popular alternative to diamonds. But one question that often arises is: does cubic zirconia turn green over time? This concern stems from misconceptions about the durability and composition of CZ. In this in-depth exploration, we’ll uncover the science behind cubic zirconia, debunk myths, and provide expert insights into how to maintain its brilliance.
Understanding Cubic Zirconia: Composition and Durability
Cubic zirconia is a synthetic gemstone made from zirconium dioxide (ZrO₂). Unlike natural diamonds, which form over billions of years under extreme pressure, CZ is created in laboratories under controlled conditions. This process ensures consistency in quality and appearance. But does cubic zirconia turn green due to its synthetic nature? The short answer is no—when properly cared for, high-quality CZ retains its clarity and color indefinitely.
To understand why, let’s examine its properties:
- Hardness: CZ ranks 8-8.5 on the Mohs scale, making it resistant to scratches.
- Refractive Index: Higher than diamonds, giving it exceptional sparkle.
- Chemical Stability: Unlike metals that oxidize, CZ doesn’t react with air or moisture.
For example, our 925 Silver Curved Opal CZ Diamond Flat Back Earrings showcase how CZ maintains its luster even when set in sterling silver.
Why Some Believe Cubic Zirconia Turns Green
The myth that cubic zirconia turns green likely originates from two sources:
- Metal Oxidation: Low-quality jewelry settings (e.g., copper alloys) can tarnish, creating a greenish residue that may transfer to the stone.
- Surface Contaminants: Lotions, perfumes, or chlorine can leave a film that dulls CZ’s shine, mistakenly interpreted as discoloration.
High-quality settings, like the 925 sterling silver used in our 925 Silver Double Round CZ Diamond Flat Back Earrings, prevent this issue entirely.
How to Prevent Cubic Zirconia from Losing Its Shine
While cubic zirconia doesn’t turn green, proper care ensures it stays radiant:
| Issue | Solution |
|---|---|
| Tarnished Settings | Choose 925 sterling silver or gold-plated bases |
| Oil/Dirt Buildup | Clean monthly with mild soap and a soft brush |
| Scratches | Store separately from harder gemstones |
Our 925 Silver Full Surround CZ Diamond Flat Back Earrings demonstrate how proper craftsmanship prevents degradation.
Cubic Zirconia vs. Other Simulants: A Comparative Analysis
Not all diamond alternatives are created equal. Here’s how CZ stacks up:
- Moissanite: More expensive but slightly yellower in tint
- White Sapphire: Less brilliant but naturally occurring
- Glass: Softer and prone to scratches
For a budget-friendly yet luxurious option, consider our 925 Silver Gold Flower Pendant Flat Earrings, where CZ outshines competitors.
