Vermeil
Also: silver-gilt, gilded silver
Vermeil is gold-plated sterling silver carrying a minimum gold layer of 2.5 micrometres, forming a distinct jewellery category that sits between solid gold and ordinary gold plating.
Vermeil (pronounced "ver-may", from the French word for "gilded") is a very specific jewellery material: a sterling silver base (fineness ≥ 925/1000) whose surface is finished by electroplating with a defined gold layer. The result marries the look of solid gold to the more affordable intrinsic value of silver.
Statutory minimum standards
The requirements for vermeil are not harmonised internationally:
| Region | Base metal | Minimum gold thickness | Gold content of coating |
|---|---|---|---|
| USA (FTC) | Sterling (925) | 2.5 µm | ≥ 10 karat (417/1000) |
| UK / EU (trade) | Sterling (925) | 0.5 – 2.5 µm | varies by supplier |
| France (traditional) | Sterling (925) | no fixed norm | often 18 karat |
There is no single statutory vermeil definition across the European Union; many makers therefore align themselves with the stricter US standard set by the Federal Trade Commission (FTC).
Distinguishing it from similar products
Vermeil should be kept clearly apart from related terms:
- Gold-filled / gold double: a mechanically rolled gold layer on a base substrate (brass, copper) — no silver core.
- Gold plating: an electroplated gold layer on any substrate, often below 0.5 µm, with no requirement on the underlying material.
- Rhodium plating: a rhodium layer on white or silver jewellery for added hardness and shine — no gold involved.
Vermeil's defining feature is its precious-metal core: anyone who melts a vermeil piece down or values it in the melt-value calculator recovers the full silver value of the base; the thin gold layer contributes almost nothing by mass.
How it is made
Vermeil is produced by electrodeposition: the cleaned sterling silver blank is dipped into a gold-bearing electrolyte bath, and a direct current deposits gold ions onto the surface. The layer thickness — measured in micrometres (µm) — governs durability and cost. The FTC minimum is 2.5 µm; pieces at 3 µm and above are sometimes marketed as "heavy vermeil".
Material value and resale
For resale, or in the silver calculator, what counts above all is the weight of the silver core multiplied by the current silver price. The gold layer is so thin — a few milligrams per gram of jewellery — that it barely registers in the melt value. A buyer will therefore normally price vermeil as plain 925 silver. (This is not tax or investment advice.)
In brief
Vermeil denotes gold-plated sterling silver held to defined minimum standards — visually on a par with gold, but in material terms a silver product. If you want to know the genuine intrinsic value, use the melt-value calculator and reckon on the silver content.
