Peking Glass is a term that has long been used in the costume jewellery trade to describe Czech. green glass stones that resemble jade. It is in fact not carved but pressed glass. The term is also used loosely to describe moulded green Czech. glass. In fact this is incorrect. Peking Glass is an elaborate procedure requiring a lot of skill! A good description can be found on Wikipedia. It originated in China in the 18th century. It is still being made in china today. I had been using the term for very many years until I realised it was quite incorrect and I no longer use it (although probably in my head it will still be Peking Glass!) You will see that the term is still used widely throughout the Internet – and people having been using it for so long – it will probably still continue to be used – but I wanted to clear up the confusion on my web site!
