Vintage Chinese Cinnabar Brooch Old China Export Carved Red Pin in Filigree 30's

Description

Vintage cinnabar style brooch for Chinese export circa 1930's.  The cinnabar is set in silver-toned metal with a filigree wire look.  The brooch is 2 1/8" x 1 5/16" and the back is stamped 'China.'  The cinnabar has some indentations on it and surface warping... it almost looks like it slightly melted or something?  The filigree has a LOT of dark patina and tarnish.  The clasp is a little hard to turn in some spots but it works well.  Please make sure to look at every photo.
