A style of bracelet usually worn by older members of the Mongolian society living in Manchuria. Coral and cloisonné beads worked with a silver repousse area of two dragon heads , a common motif on this style of bangle. The silver is of very high quality and this one has been used for many years probably dating to the end of the 19th /turn of the 20th  century. 

This is a de-accession from my own collection and was purchased in the 1980's.
