Glass is an ideal material to imitate semi-precious stones, and the ancient Romans were specialists at this. 'Calcedonia' glass was developed on the Venetian island of Murano around 1450. It was called after chalcedony, a naturally occurring hardstone. Details concerning its manufacture were kept secret for many decades. It involves mixing many different colours of glass in layers as well as a special heat treatment during blowing.
