This BIG, bold, freaky, friendly snake holds a banded agate-studded locket in his mouth. On the reverse, there's a framed glass panel that opens so you can add a photo, if you like (it may require the assistance of a local jeweler). It's made in pinchbeck, a metal alloy invented in the 18th century by a guy named Christopher Pinchbeck. It was designed to be a cheap substitute for gold, so the word "pinchbeck" has been idiomatically used to describe something fake, junky, or counterfeit.

The best “costume jewelry” during the Georgian era was pinchbeck, a top-secret formula that looked — and wore — just like gold.
