Product code: Victorian rose gold agate oval brooch saving 9ct antique vintage
I can only guess. Marked 9ct and guaranteed solid 9ct rose gold. The very large hardstone might be agate or Jasper or even carnelian. There is evidence of old jewellers cement from the reverse. Fits tight and secure. There is evidence of a much older safety chain and a new one is fitted. It's a very old brooch.
