What do gold, gold plated, gold filled and vermeil mean on a ring listing?
On a US ring listing, the word gold on its own tells you very little. The Federal Trade Commission's Jewelry Guides expect a karat number right in front of the word when the metal is a gold alloy, and they treat terms such as gold plated, gold filled and vermeil as descriptions of a gold layer over another metal rather than gold all the way through. These are advertising guidelines, not a test of any particular ring, so a label shows what the seller is claiming. This guide explains what each common word is expected to mean and what to ask before you pay.
Karat gold: the number belongs in front of the word
The Jewelry Guides, found at 16 CFR Part 23, treat the bare word gold as potentially misleading when it describes a piece that is not fine gold all the way through. Fine gold is the pure, twenty-four karat form.
For a piece made throughout of a gold alloy, the Guides expect the karat figure to come immediately before the word gold and to be at least as conspicuous, as in 14 Karat Gold.
A karat figure may also stand alone without the word gold, for example 14K stamped or listed by itself.
The Guides add a point about hollow pieces. A gold alloy ring or chain with a hollow interior should say so close to the word gold, and should not be advertised as solid.
Gold plated, gold filled and rolled gold plate
These terms describe a layer of gold alloy applied over another metal. A product called gold plated is expected to carry a surface layer of reasonable durability on all significant surfaces, with the karat figure of that layer placed immediately before the term.
Gold filled is the term the Guides tie to a mechanically applied layer, such as one soldered, brazed or welded on, and it is allowed when that layer makes up at least one twentieth of the weight of the metal in the whole article. A mechanically applied layer making up at least one fortieth of the weight can be called gold overlay or rolled gold plate, with the fraction shown in front of the karat figure.
For an electroplated layer, the Guides' example sets a minimum thickness equivalent to 0.175 microns of fine gold before a piece may be called gold plate or gold electroplate. The label Heavy Gold Electroplate is kept for a much thicker layer.
Another warning applies to layered constructions. If a gold layer has been covered by a base metal such as nickel that carries only a thin wash of gold, the Guides call for the seller to disclose that the real gold coating sits under a base metal that only has a gold wash.
Vermeil is a specific kind of gold plating
Vermeil is not just a fancy word for gold plated. The Guides allow it for a base of sterling silver that is coated on all significant surfaces with gold of at least ten karat, in a layer of reasonable durability and at least two and one half microns thick.
A related note says vermeil should not be used when the silver has been covered with a base metal such as nickel and then plated with gold, unless the seller discloses that layering. So a ring sold as vermeil should have a sterling silver base. If the listing names a different base metal, or names none, ask before you pay.
What the Guides do not settle
The Guides state the FTC's current thinking about claims, and they say they do not bind the FTC or the public. The Commission may still act if a seller's claim is inconsistent with them, but nothing here tells you whether a specific ring meets a label.
A listing almost never lets you see layer thickness, and a photograph cannot show it. The karat stamp, the plating term and any stated weight ratio are claims you can ask a seller to support in writing.
This guide covers gold terms only. It does not cover silver, platinum group metals or a rhodium surface layer, which have their own sections, and it did not read the appendix that lists exemptions in the assay of gold products.
Buyer checklist before you pay
- Find the karat figure in the title and the first line of the description, and check that it sits right in front of the word gold or is listed on its own.
- If a listing says only gold, with no karat figure and no plating term, ask the seller to state exactly what the ring is made of.
- If you see plated, filled, overlay, rolled gold or vermeil, ask what the base metal is and whether the layer covers every surface of the ring.
- For anything called vermeil, ask the seller to confirm in writing that the base is sterling silver.
- For a plated or filled ring, ask for the stated karat figure of the layer and, if the listing gives one, the thickness or weight ratio, rather than assuming either.
- Ask whether the ring is hollow, and whether the weight listed is the metal only or includes stones.
- For a finished ring, read our setting-only guide to confirm what the price includes before comparing metals.
Limits of this guide
This guide reads the public text of three sections of the US Jewelry Guides as hosted by Cornell's Legal Information Institute on the retrieval dates listed below. It is not legal advice, and no lawyer has checked it.
The Guides are US advertising guidance. Sellers and listings in other countries may follow different rules, and the hosted text may lag behind the official government version.
