Gold-filled is a thick sheet of 10 to 14 karat gold bonded with heat and pressure to a brass core. The gold layer usually represents at least 5% of the piece's total weight, so it is far more durable than simple plating.

## Properties

- **Composition:** brass or copper core with a 10-14K gold layer.
- **Gold thickness:** many times that of an electroplated coat.
- **Process:** bonding by heat and pressure, not electrolysis.
- **Marking:** usually stamped “GF” or “1/20 14K GF”
- **Price:** between plating and solid gold.

## Uses in jewelry

- Everyday chains, earrings and pendants.
- Handmade jewelry with wire and sheet.
- An alternative to solid gold with good durability.

## Pros and cons

### Advantages

- Lasts years without wearing through if cared for.
- Much cheaper than solid gold.
- Usually hypoallergenic, though it depends on the layer.

### Limitations

- If heavily scratched, the base metal shows.
- Cannot be repaired like solid gold.
- Has less resale value.

## Care and cleaning

- Clean with lukewarm water, mild soap and a cloth.
- Avoid bleach, chlorine and abrasive products.
- Take it off to shower or exercise.
