Pinchbeck (alloy) – Harry & Co Jewellery

Definition and Origin of Pinchbeck

Pinchbeck is an alloy of copper and zinc that closely resembles gold in appearance.
It was invented in the early 18th century by Christopher Pinchbeck, a London clock- and watch-maker.
Pinchbeck allowed ordinary people to buy gold effect jewelry on a budget as gold was only sold in 18-carat quality at that time.
Pinchbeck jewelry was used in places like stagecoaches to prevent theft.
The original Pinchbeck was made by Christopher Pinchbeck and his descendants until the 1830s.

Dishonest jewelers passed off Pinchbeck as gold, leading to its association with cheap and tawdry imitation.
Over the years, the name Pinchbeck came to mean any gilt metal, depending on the dealer.
Pinchbeck fell out of use in the second half of the 19th century and was replaced by low-carat gold.
Low-carat gold became legal in 1854, providing a more affordable alternative to Pinchbeck.
Pinchbeck is typically composed of copper and zinc in ratios of 89% copper to 11% zinc or 93% copper to 7% zinc.

Gilding metal is another alloy used for gilding and has a similar appearance to Pinchbeck.
Princes metal is a copper-zinc alloy used for imitation gold jewelry.
These alloys are related to Pinchbeck and have similar applications.
