This is an interesting 3 dimensional pin with a group of cherubs that are holding hands and possibly dancing. The far left cherub seems to have a wing so perhaps he/she is an angel. The design is raised so appears to be three dimensional. I am unable to find a mark but believe it to be silver and at least 800.
This brooch is a very nice size measuring 2.25 inches by 1 3/8 inches. Please feel free to contact me with any questions.
