Avoid Water and Chemicals: Since water, especially chlorinated or salt water, and chemicals like lotions and perfumes can cause tarnishing or wear down the gold layer, it's best to keep your gold vermeil jewellery away from them.

Proper Storage: Storing your jewellery in a dry, dark place—such as a soft pouch or lined box—helps prevent scratching and oxidation. This environment also protects it from the moisture that can cause tarnishing.

Gentle Cleaning: Using a soft cloth to wipe your jewellery is perfect, as abrasive cloths or cleaners may scratch or wear down the thin gold layer over time.
