Gold Filled vs. Gold Plated vs. Vermeil vs. Solid Gold

A gold plated necklace and a gold filled one can look exactly the same when they're new. After a few months of daily wear, though, you can usually tell them apart, because the plated one starts to fade or leave a green mark on your neck.

Solid gold is gold all the way through. Gold filled has a thick layer of real gold bonded to a core metal. Vermeil is a thinner layer of gold over sterling silver, and gold plated is a very thin coating over an inexpensive base metal. Here's a closer look at each one.

Solid Gold

Solid gold is gold alloy all the way through, with no other metal underneath. The karat tells you how much of it is pure gold: 10k is about 42% gold, 14k is about 58%, 18k is 75%, and 24k is pure gold. The rest is other metals like silver, copper or zinc, which make it harder and more durable.

Solid gold won't wear off or tarnish, and it can be repaired, resized and passed down. The tradeoff is price. A dainty solid gold chain often costs several times more than the same style in gold filled, which is why most people save solid gold for heirloom pieces like wedding bands.

Gold Filled

Gold filled jewelry has a thick layer of real gold that's bonded to a core metal (usually brass) with heat and pressure, rather than electroplated on. Despite the name, the gold isn't in the middle. It's on the outside, wrapped around the core.

There's a legal standard behind the term. In the U.S., the FTC only allows a piece to be called gold filled if the gold layer is at least 10k and makes up at least 1/20 (5%) of the item's total weight. That's why you'll often see gold filled wire and chain stamped "1/20 14K GF."

Because the gold layer is so much thicker than plating, gold filled holds up to everyday wear for years, and often much longer with a little care. It doesn't flake or rub off the way plating does, and most people with sensitive skin can wear it comfortably since the gold covers the core metal. It also costs much less than solid gold, so it's what I'd pick for anything you plan to wear every day.

Gold Vermeil

Vermeil (pronounced ver-MAY) is sterling silver with a layer of gold plated over it. To use the name in the U.S., the base has to be sterling silver and the gold has to be at least 10k and at least 2.5 microns thick. That's thicker than regular plating, but still a very thin layer.

Vermeil is a step up from regular gold plating, and the sterling silver base means there's real value under the gold. But it's still a plated layer, so it will eventually wear through on parts that rub against skin or clothing, like clasps, ring bands and the backs of pendants. When it does, the silver underneath shows and can tarnish.

Gold Plated

Gold plated jewelry is a base metal, often brass, copper or nickel, with a very thin layer of gold applied by electroplating. Under the FTC guides, that layer can be as thin as 0.175 microns of fine gold and still be called gold plated or gold electroplated. Anything thinner gets labeled "gold flashed" or "gold washed."

A lot of inexpensive fashion jewelry is gold plated, and it can look really nice when it's new. But a layer that thin tends to rub off within weeks or months of regular wear, especially with water, lotion and sweat. Once the base metal is exposed, it can tarnish, turn dark, or leave a green mark on your skin. Gold plated pieces are fine for occasional wear, but they're not built to be worn every day.

Which one should you choose?

It depends on how you'll wear it. If it's a piece you'll put on once and never take off, like a wedding band, solid gold is worth the investment. If it's a fun piece for a night out, gold plated is fine. For the necklaces and earrings you wear most days, I think gold filled makes the most sense. It's real gold, it holds up to daily wear, and it costs a lot less than solid gold.

That's why every piece at Coastal Summit Studio is made with 14k gold filled wire and chain. I want you to be able to put on a necklace in the morning and forget about it, without wondering whether it'll still look the same next year. I pair it with natural stones like moss agate and jasper, and make each piece by hand here in Marin County.

Frequently asked questions

Is gold filled real gold? Yes. The outer layer is real karat gold, usually 14k, and by law it makes up at least 5% of the piece's total weight. It's not solid gold, but it's far more gold than plating.

Does gold filled jewelry tarnish? Gold itself doesn't tarnish, so gold filled holds its color well. Over time it can pick up a little dullness from lotions, perfume or everyday grime, and a gentle clean with mild soap and water and a soft cloth brings the shine back.

Can I shower in gold filled jewelry? It can handle the occasional splash, but I recommend taking it off before showering, swimming or soaking in a hot tub. Soap, chlorine and salt water dull the finish over time and can be hard on gemstones.

Is gold filled better than vermeil? For everyday wear, usually yes. Gold filled has a much thicker gold layer, so it holds up longer to daily rubbing. Vermeil has a sterling silver base, which some people prefer, but its thinner gold layer wears through sooner.

How can I tell what a piece is made of? Check the stamp or the product description. Gold filled is often marked "1/20 14K GF," vermeil is marked "925" with a gold karat, and solid gold is marked with its karat alone, like "14K." Terms like "gold tone" or "gold toned" usually mean there's no real gold at all.
