It’s much better-- gold fill jewelry contains literally 100x more gold than plated pieces. Gold plating is paper thin and often chips or wears through after a few uses, revealing the fast-tarnishing base metal underneath. In contrast, the thick gold layer on gold filled pieces is securely bonded to its core, ensuring that your jewelry remains in pristine condition for many years of regular wear.
Almost definitely not. ALL of our jewelry is nickel free, and the thick layer of gold on gold filled pieces makes it safe for sensitive skin. However, everyone’s individual skin chemistry is different, and a small number (less than 1%) of wearers will experience slight skin discoloration or tarnishing.
