Turquoise Heart Chalcedony Pinchbeck Cloak Pin Brooch Antique Victorian c1860
Pinchbeck is a form of brass, an alloy of copper & zinc, mixed in proportions so that it closely resembles gold in appearance. It was invented in the 18th century by Christopher Pinchbeck, a London clockmaker. 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. It also allowed the wealthy to make copies of their priceless jewels that could be worn on their travels, still looking fabulous without the risk of theft from highwaymen.
