This is a beautiful vintage Art Deco faceted drop pendant in gorgeous pink glass in a filigree mount. It is most likely Czech in origin but it is unmarked. It is on a sterling silver chain, marked 925 Italy on the catch, which is a replacement.
The pendant measures about 1 1/4 inches by about 7/8 inch and the chain is 19 inches long. The pendant is in good condition, but it does have some small fleabite chips along the edge and next to where the mount attaches. I also see a couple of light surface scratches and a small dark flaw in the glass. It still looks beautiful on.
