Gold Vermeil, Explained Plainly: 2.5 Microns and the Legal Floor
What vermeil legally means in the US, how it differs from gold plating and gold filled, and why the base metal under the gold matters more than the karat.

Vermeil is a legal term in the United States, not an adjective a brand can stretch. To use it, a piece needs a sterling silver base, a gold layer of not less than 10 karat fineness on all significant surfaces, and a minimum thickness equivalent to 2.5 microns of fine gold. Miss one and the word becomes a deceptive claim.
Three conditions, and the one that gets dropped
The definition sits in 16 CFR 23.4, part of the FTC’s Guides for the Jewelry, Precious Metals and Pewter Industries. Two conditions get repeated everywhere: the sterling base and the 2.5 microns. The third, the 10-karat floor, quietly drops out of most sales copy. The same section requires disclosure where a base metal such as nickel sits between silver and gold, and asks for gold “of reasonable durability” — a phrase, not a number.
| Base metal | Gold layer | Legal wording | |
|---|---|---|---|
| Vermeil | Sterling silver, 92.5% silver | At least 10K, at least 2.5 microns | “vermeil” |
| Gold electroplate | Any base metal, including brass | From roughly 0.175 microns upward | “gold plated” |
| Gold filled | Base-metal core, usually brass | At least 10K, layer at least 1/20 of total weight | “1/20 14K gold filled” |
Why the base metal outranks the karat
14K and 18K change the surface colour and, slightly, its hardness. Neither changes what you see when the layer fails. Abrasion removes gold until the metal underneath is exposed, and that metal is what shows. On sterling it is silver: pale, grey, harmless to most skin. On brass or nickel it is a different colour, and with nickel it can be a reaction.
Where plating fails, and what repair costs
Wear is never even. It concentrates where surfaces rub: the back of a ring shank, a clasp tongue, the jump rings beside a clasp, the inner face of a bangle, the chain links that move most. Chlorine is the fastest accelerant, attacking the gold and the silver beneath it, which is why pools and daily showering shorten a piece’s life more than any other habit. Perfume, sunscreen and hairspray act more slowly in the same direction.
Repair is possible: a jeweller strips the remaining gold, repolishes the sterling and electroplates a fresh layer. Replating services commonly quote tens of dollars per piece, not hundreds, varying with size and complexity. On a brass core that work rarely pays; on sterling it often does.
The micron count tells you how long the gold lasts. The base metal tells you what happens afterwards.
Who should skip vermeil entirely
Skip it for a wedding band, an engagement ring, or anything you mean to hand down. Rings take more friction than any other piece and meet water and soap most often. Skip it too if you want jewellery you never think about. Vermeil suits earrings, pendants and chains. If you are weighing the silver core itself, sterling against fine silver is the next question, and how silver behaves in storage decides how much of this you will see.
FAQ
- Is gold vermeil real gold?
- The layer is genuine gold of at least 10 karat, over a sterling silver core. It is not solid gold.
- Does vermeil tarnish?
- The gold does not. The silver beneath it does, once the gold thins or wears through at a contact point.
- Can vermeil be replated?
- Yes. A jeweller strips the old layer, repolishes the sterling and electroplates fresh gold.
