Vermeil
Also: Silver-gilt, Silver gilding
Vermeil refers to gold-plated sterling silver with a minimum gold coating of 2.5 micrometres, positioned as a distinct jewellery category between solid gold and simple gold plating.
Vermeil (pronounced ver-may, from the French for "gilded") is a specific jewellery material: a sterling silver substrate (fineness ≥ 925/1000) whose surface is finished by electroplating with a defined gold layer. The result combines the look of solid gold with the more affordable intrinsic value of silver.
Statutory Minimum Standards
The requirements for vermeil are not uniformly regulated internationally:
| Region | Substrate metal | Minimum gold thickness | Gold content of the coating |
|---|---|---|---|
| USA (FTC) | Sterling (925) | 2.5 µm | ≥ 10 carat (417/1000) |
| UK / EU (trade) | Sterling (925) | 0.5 – 2.5 µm | varies by supplier |
| France (traditional) | Sterling (925) | no standard | often 18 carat |
In the European Union there is no uniform statutory vermeil definition; many manufacturers follow the stricter US standard of the Federal Trade Commission (FTC).
Distinction from Similar Products
Vermeil must be clearly separated from related terms:
- Doublet / gold doublet: Mechanically rolled-on gold layer on a base substrate (brass, copper) – no silver substrate.
- Gold plating: Electroplated gold coating on any substrate, often under 0.5 µm – with no requirement for the base material.
- Rhodium plating: Rhodium coating on white or silver jewellery for increased hardness and shine – no gold.
Vermeil's unique feature lies in the precious metal substrate: anyone who melts down a vermeil piece or values it in the melt value calculator obtains the full silver material value of the substrate; the thin gold layer contributes hardly anything in terms of quantity.
Manufacture
Vermeil is produced by electrolytic deposition: the cleaned sterling silver blank is immersed in a gold-bearing electrolyte bath; a direct current deposits gold ions onto the surface. The layer thickness – measured in micrometres (µm) – determines durability and cost. The FTC minimum requirement is 2.5 µm; pieces of 3 µm and above are sometimes marketed in the trade as "heavy vermeil".
Material Value and Purchasing
When purchasing, or using the silver calculator, it is primarily the weight of the silver substrate multiplied by the current silver price that counts. The gold layer is so thin (a few milligrams per gram of jewellery) that it practically does not register in the melt value. A buyer will therefore usually calculate vermeil as 925 silver. (No tax or investment advice.)
In Brief
Vermeil stands for gold-plated sterling silver with defined minimum standards – visually at gold level, but in material value a silver product. Anyone who wants to know the true intrinsic value uses the melt value calculator and calculates using the silver content.
