It's 14k gold filled, not gold plated. Gold filled bonds a thick layer of solid 14k gold to a base metal core under heat and pressure — roughly 100 times more gold than plating. That layer doesn't flake, wash off, or wear through with normal use, which is why you can wear these pieces in the shower, at the pool, and at the beach.

Never. Gold filled doesn't tarnish the way plated jewelry does, and it won't leave green marks on your skin from normal wear. If a piece dulls over time, a soft polishing cloth restores it.

Gold filled is an excellent option for people who react to costume jewelry, because the surface your skin touches is solid, genuine 14k gold rather than a thin plating over unknown metal.  14 karat gold does not contain nickel, and therefore should not cause any irritation for those who are sensitive to nickel or have a nickel allergy.
