How to Keep Your Gold-Plated Jewellery Looking Like New

For gold-plated jewellery, 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 jewellery, 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 jewellery is by polishing it off using a soft cloth to remove dirt and dust.

If your jewellery requires a deeper clean, Okubo recommends using warm soapy water to clean it. “Soak your jewellery 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.

While you want to treat all your gold jewellery with the same care, earrings do tend to get more wear than necklaces and bracelets, according to Okubo, so be sure to clean them more often if you wear them all the time. For good measure, she recommends her customers clean their earrings once a week if they’re wearing them regularly.

It’s best not to use gold-plated jewellery when you’ve already applied products like lotion, hairspray, sunscreen, and shampoo. If you’re handling cleaning products like bleach, it’s better to take off the jewellery beforehand, Okubo said.

“Body lotions and creams, unfortunately, contain chemicals that speed up tarnishing and damage,” she said. “I know that it’s hard to not wear them – but just know that this will shorten the life of your plated jewellery.”

The kind of gold plating also plays a role in how long or where you should wear your jewellery. Ideally, you’d want the plating to be a thicker layer to preserve the longevity of your jewellery, Okubo said. For example, gold-vermeil jewellery has a solid sterling silver with a thick layer of 14k gold. While nickel can help stabilise gold to make it last longer, many wearers are allergic to the metal, so Maison Miru applies a thick layer of 14k gold to help their pieces last longer.

Even the type of gold can determine how long it may last. For example, 14k gold tends to be harder and less malleable than 18k or 22k gold, Okubo said.

“Gold is a super-soft metal, and the more pure it is (the higher the karat number), the softer it is,” she said. “I chose 14k gold as a good balance between beauty and durability.”
