Chinese export ring

This is a vintage Chinese export ring that I am holding back to do further research. It is marked China Silver, but also LiU, which appears to be an artist name. It is set with genuine jadeite and seed pearls. There is some damage in the pearl area. The silver is 925 sterling and has a light gold wash. The filigree work is done in a grape bunch theme and very detailed. Just wanted to share! If you know anything about "LiU", do tell.
