# Gold-plated vs solid gold: the clear guide

Published on **25/07/2026** · By **Sébastien Joumel**

In brief

**The difference between gold-plated and solid gold comes down to where the gold is: plating is a thin gold layer (at least a few microns) over a base metal, while solid gold is a gold alloy all the way through.** One wears away over time, the other is near-eternal and holds its value. Here's how to tell them apart and choose.

## Definitions: where is the gold?

**Solid gold:** the piece is a gold alloy throughout. "Solid" doesn't mean pure: 18-carat gold contains 75% fine gold (750‰), the rest being other metals. There's also 14 ct (585‰) and 9 ct (375‰).

**Gold-plated:** a base-metal core (brass, copper) covered with a **thin gold layer**. In France, "plaqué or" requires at least **3 microns**; below that it's "gilded" or "flashed", far less durable.

## Durability: the real divider

This is what shows with wear. A plating's layer eventually **wears away** (friction, sweat, cosmetics), revealing the metal beneath, often within a few years depending on use. Solid gold never exposes anything else: scratched or polished, it's gold all the way through. A solid piece is passed down; a plated one is replaced.

## Price and value

Solid gold costs considerably more upfront but **holds value** (real gold weight, resale at the daily rate, buy-back). Plating is affordable and perfect for following trends or owning many pieces, but its resale value is near zero. The right choice depends on use: a keeper for daily wear (solid) or a trend accessory (plated).

## How to tell them apart

-   **The hallmark:** solid gold carries a fineness hallmark (eagle head for 18 ct). Plating carries at most a "plaqué or" mark or a square, never the solid-gold hallmark.
-   **Weight:** at equal size, solid gold is heavier and denser in the hand.
-   **Wear:** an area where the gold has gone, showing a yellow-pink or grey metal, reveals plating.
-   **Magnet:** gold isn't magnetic; if the piece is attracted, its core isn't solid gold (an indicative, not definitive, test).

For a valuable piece in doubt, a jeweller or assayer settles it. See also our [jewellery care guide](https://meilleures-bijouteries.fr/en/guides/how-to-clean-jewellery/).

## Which should you choose?

**Go for solid gold** if you want a piece to keep, pass down or resell (wedding band, signet ring, statement piece). **Choose gold plating** for a controlled budget, trend pieces or items you renew — as long as you care for it gently to preserve the gold layer.

## Frequently asked questions

What is the difference between gold-plated and solid gold?

Gold plating is a thin gold layer (at least 3 microns in France) over a base metal, which wears over time. Solid gold is a gold alloy throughout (75% gold for 18-carat), near-eternal and holding its value.

Does gold-plated jewellery have value?

Its resale value is near zero, as the actual gold content is minimal. It's valued for its low price and look, but is not an investment, unlike solid gold.

How do I recognise solid gold?

Look for the fineness hallmark (eagle head for 18-carat gold), weigh the piece (solid gold is dense), and check wear: plating reveals another metal at friction points. When in doubt, have it checked by a jeweller.
