Does Cubic Zirconia Turn Green? The Truth Behind the Sparkle

When it comes to affordable luxury, cubic zirconia (CZ) has long been a favorite for jewelry lovers. But one question keeps popping up: does cubic zirconia turn green? The short answer? No—but there’s more to the story. Let’s dive into the science, myths, and styling tips to keep your CZ jewelry looking flawless.

What Is Cubic Zirconia?

Cubic zirconia is a lab-created gemstone designed to mimic the brilliance of diamonds. Unlike natural stones, CZ is synthesized under controlled conditions, resulting in a flawless, budget-friendly alternative. But unlike some metals or alloys, cubic zirconia does not oxidize or tarnish, meaning it won’t turn green over time.

Why Do Some People Think CZ Turns Green?

The misconception that cubic zirconia turns green likely stems from confusion with low-quality metal settings. If a CZ stone is set in cheap plated metal (like nickel or copper alloys), the metal itself may oxidize, leaving a greenish residue on the skin. The stone, however, remains unaffected.

For example, our 925 Silver Curved Green CZ Diamond Double-Sided Earrings feature sterling silver settings, ensuring no discoloration over time.

How to Keep Your CZ Jewelry Looking Pristine

To prevent any green tint (from metal, not the stone!), follow these care tips:

  • Choose quality settings: Opt for sterling silver, gold-plated, or surgical-grade metals.
  • Clean regularly: Use a soft cloth and mild soap to remove oils and dirt.
  • Store properly: Keep jewelry in a dry, airtight container to avoid exposure to moisture.
