The "green thing" in earrings typically refers to the patina or tarnish that can develop on metal components, especially copper or copper alloys, due to oxidation and exposure to moisture. This greenish discoloration is common in costume jewelry and can sometimes occur if the earrings contain metals that react with sweat or other environmental factors. Regular cleaning and proper storage can help prevent or minimize this effect.
