For gold-plated jewelry, which is a layer of gold over a base metal, you want to keep it away from water. And when you're not wearing gold-plated jewelry, like Maison Miru's 14k-coated pieces, placing it in an airtight bag will keep the metal from tarnishing, Okubo said. She added that the best way to clean your jewelry is by polishing it off using a soft cloth to remove dirt and dust.
If your jewelry requires a deeper clean, Okubo recommends using warm soapy water to clean it. "Soak your jewelry in the water for a few minutes and then clean it with a soft cloth, drying it immediately afterward," she said.
Mejuri uses 18k gold vermeil, according to Lançon, who recommends using the brand's Jewelry Care Kit to keep the brand's pieces looking their best.
