18K gold plated stainless steel earrings can tarnish over time, but they’re less likely to turn your skin green than many cheaper fashion metals. The stainless steel core is corrosion-resistant, so most discoloration issues happen when the thin gold layer wears down and is exposed to air, moisture, sweat, and product buildup.
Gold plating is a surface layer, not solid gold. With daily wear, friction and contact with water, lotion, perfume, hairspray, and sweat gradually thin that layer. Once the plating starts to wear, the surface can look dull, patchy, or slightly darker—especially around edges and posts where rubbing is constant. Stainless steel itself doesn’t typically “rust” like some metals, but residue and oxidation on the surface can still make jewelry look less bright.
Turning green is usually linked to copper reacting with sweat and acids on the skin. Since stainless steel doesn’t contain the same high-copper content as many alloys, green marks are uncommon. If green discoloration happens, it’s often due to worn plating exposing a mixed metal component (in some designs), or reactions with skincare products rather than the stainless steel base itself.
To extend the life of the plating, put earrings on after applying skincare and fragrance, and remove them before swimming, showering, or exercising. Wipe them gently with a soft, dry cloth after wear to remove oils and residue, and store them in a dry pouch or jewelry box. Avoid harsh cleaners and abrasive polishing, which can strip plating faster.

Use a soft microfiber cloth to wipe them after wearing. If needed, lightly dampen the cloth with water, wipe gently, then dry completely—skip chemical jewelry dips and anything abrasive.
