Chinese Chop
In China, the ‘chop’ is common and most documents are not considered viable unless they are ‘chopped’. The chop, or seal, is a symbol of authenticity and proves that the accompanying signature is the real deal. Good and real chops are made from soft stone. Chops can be made from other materials, but usually they are cheap and do not carry the gravitas of stone. The image below is my chop which contains my Chinese name. :-)
