The "Last On, First Off" Rule: Always put your jewelry on after applying makeup, hairspray, lotions, or perfume. Chemicals in these products can dull the stones and erode the metal plating over time.
Avoid Moisture: Remove your earrings before showering, swimming (especially in chlorinated pools), or exercising. Sweat and salt water can lead to premature tarnishing.
Safe Handling: When removing your earrings, grasp them by the metal base rather than pulling on the stones to ensure the settings remain secure.
