What Is Gold Vermeil? Vermeil Jewelry Explained

Under the FTC Jewelry Guides, vermeil means a sterling silver base coated or plated on all significant surfaces with gold of at least 10 karat, at a minimum thickness equivalent to 2.5 microns of fine gold. Gold vermeil is real gold over real silver, but it is not solid gold.

• That the gold layer meets the 2.5-micron minimum
• How much of the gold layer is left after wear
• That the piece is solid gold, or that a 925 stamp covers the gold layer

1. 1Look for 925, sterling, or a silver hallmark, and for the word vermeil or a gold-plating term near it
2. 2Inspect edges, clasps, and the inside of rings for pale silver showing through the gold
3. 3Ask the seller to state the gold karat and layer thickness in writing

What vermeil means under the FTC Jewelry Guides

The FTC Jewelry Guides define vermeil in 16 CFR 23.4. A product may be marked or described as vermeil if it has a base of sterling silver, coated or plated on all significant surfaces with gold or gold alloy of at least 10 karat, of reasonable durability, and with a minimum thickness throughout equivalent to 2.5 microns of fine gold. The Guides put that at about 100 millionths of an inch.

Each part of the definition does work. The base has to be sterling, which U.S. rules define as at least 925 parts per thousand silver, so gold over brass or copper is not vermeil. The gold has to be at least 10 karat. And the thickness is stated as an equivalent of fine gold. In their gold electroplate rules the Guides explain that 1 micron of 12-karat gold equals half a micron of 24-karat gold, so a lower-karat layer has to be thicker. By that conversion, a 14-karat layer needs roughly 4.3 microns and a 10-karat layer roughly 6 microns to reach the vermeil minimum.

A note to the definition closes a common shortcut. If the sterling is first covered with a base metal such as nickel and then gold plated, calling the product vermeil is deceptive unless that base-metal layer is disclosed. FTC consumer guidance sums vermeil up as a special type of gold-plated product with a sterling silver base.

Vermeil versus gold plated, HGE, and gold filled

All four put real gold over another metal. They differ in the base, the thickness, and the way the gold is applied. Vermeil is not automatically thicker than every other gold layer: heavy gold electroplate has the same 2.5-micron minimum. What sets vermeil apart is the precious metal underneath. When its gold wears through, it shows sterling silver, while plated brass or copper shows base metal.

The GP and GF pages explain those marks, and the plated versus filled versus solid gold guide compares the constructions in depth. The minimums in the FTC Guides are:

• Vermeil: sterling silver base; gold of at least 10 karat; at least 2.5 microns equivalent of fine gold.
• Gold electroplate (GEP): any base; gold of at least 10 karat; at least 0.175 microns equivalent of fine gold.
• Heavy gold electroplate (HGE): any base; gold of at least 10 karat; at least 2.5 microns equivalent of fine gold.
• Gold filled (GF): a karat gold layer of at least 10 karat, mechanically bonded to a base metal and making up at least 1/20 of the weight of all the metal. Rolled gold plate needs at least 1/40.

Gold vermeil in the UK

UK guidance on gold-plated silver treats vermeil as gold-plated silver. When the word gold or a gold fineness is used, the article must be described as silver, and gold must be directly followed by plated, as in “18ct gold plated silver ring”. Vermeil may be added, but the phrase gold plated and the word silver must still appear in the description.

The same guidance gives “22ct gold vermeil ring” as an example of a misleading description, because the items were silver with thin gold plating and the description mentioned neither silver nor plating. Silver gilt may be used for gold-plated silver as long as no gold fineness is attached to it.

Two more points differ from U.S. practice. The guidance says gold-plated silver is hallmarked as silver, so a UK hallmark on vermeil is a silver hallmark. It also says the plated gold layer must be at least 375 fine and should not exceed 2 microns in thickness, while the U.S. definition of vermeil starts at 2.5 microns of fine gold.

How to recognize vermeil from its marks

Because the body is sterling, vermeil usually carries a silver mark: 925, sterling, or in the UK a full silver hallmark. FTC consumer guidance adds that silver items must also show the name or U.S. registered trademark of the company or person behind the mark, so look for a maker’s mark beside the number. The word vermeil, or a karat followed by a plating term, may appear as well.

A gold-colored piece stamped 925 is consistent with vermeil, but also with sterling that has a thinner gold plate or a gold-colored finish. The stamp describes the silver. It does not state the karat of the gold or its thickness, and nothing you can see on the surface measures microns. A listing that says vermeil is making the full FTC claim, so ask for the karat and thickness in writing.

Avoid the reverse mistake as well. 925 on a yellow piece is not a gold mark and does not mean 92.5 percent gold, and a vermeil piece should not be priced as solid gold. The 925 page explains the silver claim in detail, and how to tell if silver is real covers the checks for the metal underneath.

How vermeil wears and how to care for it

The gold layer wears first where the piece rubs: ring shanks, clasps, chain links, the backs of pendants, and the edges of earrings. Look there under a loupe for pale silver coming through the yellow. Once the sterling is exposed, it can tarnish. The Canadian Conservation Institute describes silver tarnish as mainly black silver sulphide formed by sulphur compounds in the air, so worn vermeil can show dark patches at its edges.

Polishing is the main risk. The same CCI guidance warns that every polish or chemical tarnish removal on silver takes away some of the underlying metal, and that general-purpose metal polishes are more abrasive than silver polishes. On vermeil the surface you would be polishing is a gold layer only a few microns thick, so wipe it with a soft cloth and avoid abrasive polishes and dips.

A worn piece can usually be re-plated by a jeweler. That restores the color with a new layer, so ask what karat and thickness the new plating will be if you want the piece to still meet the vermeil definition.
