Have this pin that came in a lot. Nice stone with a chip. Rock measures 1" by .5". It’s slightly loose with a little slip slide in setting. Nice rock. The filigree work is probably some of the finest. Hardware works perfect. Marked: SILVER, CHINA -Tested as 800 Silver
Keep as an antique piece or stone could be removed easily for jewelry making. The remaining stone seems solid. Just a thought -don’t know anything about jewelry making.
Think the piece is worth twice what I’m asking - $85 or trade for Art Deco or wedding jewelry.
