Signed: Czechoslovakia Size: 2.6 x 3.5 cm. (1 x 1.3 inches) Weight: 8 gr. Pinchbeck is a form of brass, an alloy of copper and zinc mixed in proportions such that it closely resembles gold in appearance. It was invented in the early-18th century by Christopher Pinchbeck (died 1732), a London clock-and watch-maker.[1] Since gold was only sold in 18-carat quality at that time, the development of pinchbeck allowed ordinary people to buy gold-”effect” jewellery on a budget. The inventor allegedly made pinchbeck jewellery clearly labelled as such.
