Does Cubic Zirconia Turn Green? The Truth Behind This Popular Gemstone

Understanding Cubic Zirconia Composition

Cubic zirconia (CZ) has become one of the most popular diamond alternatives in modern jewelry. This synthetic gemstone is made from zirconium dioxide (ZrO₂) and is prized for its brilliant sparkle and affordability. But many wonder: does cubic zirconia turn green over time like some other jewelry materials?

The answer lies in the material's fundamental properties. Unlike costume jewelry that uses plated metals, high-quality cubic zirconia stones themselves don't contain elements that oxidize into green tones. However, the settings they're placed in can sometimes cause discoloration issues.

Why Some Jewelry Discolors Over Time

Before addressing does cubic zirconia turn green, it's important to understand why some jewelry changes color. The green discoloration people sometimes see comes from:

• Copper content in base metals oxidizing
• Nickel alloys reacting with skin oils
• Low-quality plating wearing off
• Chemical exposure from cosmetics or cleaning products

This table shows common jewelry materials and their discoloration potential:

Does Cubic Zirconia Turn Green? The Science Explained

The cubic zirconia stone itself will not turn green - this is one of its advantages over other simulated diamonds. The zirconium dioxide crystals are extremely stable and don't react with oxygen or moisture. However, there are three scenarios where you might notice green discoloration:

1. Low-quality metal settings: If the CZ is set in brass or copper alloy, the metal may oxidize and leave green marks on skin
2. Plating wear-off: Gold or rhodium plating that wears away can expose base metals that oxidize
3. Adhesive issues: Some glued settings use compounds that can degrade and discolor

For jewelry that maintains its beauty, consider these stunning 925 Silver Heart Shape CZ Diamond Flat Back Earrings ($34), which feature high-quality sterling silver settings that resist tarnishing.

• Clean regularly with a soft jewelry cloth
• Store pieces separately in anti-tarnish bags
