Solid gold jewelry is made of gold alloy all the way through. Gold-plated jewelry is a base metal, usually brass or silver, with a thin layer of gold on the outside. They can look identical in a product photo, but only one of them is still gold in six months. The plating wears through with normal contact: skin oils, moisture, friction from clothing. What's left underneath is whatever metal the piece was really made of.

What's actually inside gold-plated jewelry?
Gold plating is applied through electroplating: a piece is made from a base metal, usually brass, copper, or silver, then dipped in a gold solution and run through an electric current that bonds a thin layer of gold to the surface. That layer is measured in microns, and it is thin. Most costume and fast-fashion "gold" jewelry uses a plating layer thinner than a human hair.
Gold vermeil is a step up: sterling silver plated with a thicker, regulated layer of gold. It holds up longer than standard plating, but it is still a coating, not the piece itself.
Why does gold plating fade?
Because it's a surface layer, not a material. Every time plated jewelry touches skin, lotion, perfume, or water, a microscopic amount of that gold layer wears away. High-contact points, like the back of an earring post or the inside of a ring, wear fastest. Within six months to two years of regular wear, the base metal starts to show through, usually as a dulling or a color shift where the piece rubs against skin or clothing.
If the base metal is brass or copper, the exposed metal can also react with skin oils and oxidize, which is the green or gray discoloration people sometimes notice on cheaper jewelry. That reaction is coming from the base metal, not the gold.
How solid gold is different
Solid gold jewelry is made from a gold alloy from the outside in. There's no separate layer to wear off, because the entire piece, not just the surface, is the gold alloy itself. At Zahav, every piece is cast in 10K or 14K solid gold, with the karat stamped on the listing, not hidden behind a vague "gold-tone" or "gold-filled" description.
That also means solid gold can be cleaned with soap and water, worn in the shower, and polished without worrying about removing the finish, because there is no separate finish to remove.
Solid gold from the post to the hinge, starting at $135.
How to tell solid gold from plated before you buy
- Read the listing, not just the photo. "Gold-plated," "gold vermeil," "gold-filled," and "gold-tone" all mean a coating. "Solid gold," "10K," "14K," or "18K" with no other qualifier means the metal is gold throughout.
- Check for a karat stamp. Solid gold jewelry is almost always marked with its karat (10K, 14K, 18K) somewhere on the piece, usually on the clasp or post. Plated jewelry typically isn't, because there's nothing to certify.
- Compare the price to the category. A pair of solid gold huggies and a pair of gold-plated huggies can look the same in a photo, but solid gold cannot be sold at fast-fashion prices. If a "gold" piece is priced like a $15 accessory, it isn't solid gold.
- Ask what's underneath. A brand that's confident in its materials will tell you the base metal under the plating, or the karat of the solid gold, without you having to dig for it.
Does solid gold cost more, and is it worth it?
Yes, solid gold costs more upfront than plated jewelry, because it contains significantly more actual gold. According to the Gemological Institute of America (GIA), gold jewelry is alloyed with other metals for strength and marked by karat to indicate how much pure gold it contains, information that only applies to solid gold, since plated pieces are not karat-rated.
The tradeoff is straightforward: plated jewelry needs to be replaced every six months to two years as the layer wears through. Solid gold, cared for normally, keeps its color and structure for years, and it holds real resale and scrap value because the gold content is real. Over time, buying once tends to cost less than buying the same plated piece repeatedly, and it never has that moment where the color suddenly turns.
Frequently asked questions
Can gold plating be reapplied once it wears off?
Yes, some jewelers offer re-plating services, but it adds an ongoing cost and the piece has to be sent out each time. Solid gold never needs this, since there's no plating to redo.
Is gold vermeil the same as solid gold?
No. Gold vermeil is sterling silver with a thicker layer of gold plating over it. It's a better-quality coating than standard plating, but it's still a coating over a different base metal, not solid gold.
Will solid gold ever turn colors or tarnish?
Solid gold itself doesn't tarnish. Some people notice slight surface dulling from skin oils or lotion residue over time, which is a buildup on the surface, not a change in the metal, and it comes off with a soft polishing cloth.
How can I tell if a piece I already own is solid or plated?
Look for a karat stamp (10K, 14K, 18K) on the clasp, post, or inside band. If there's no stamp and the listing didn't specify a karat, it's most likely plated or gold-filled.
