This is a beautiful antique Victorian citrine pin set in 800 silver with a lovely floral motif. The oval stone is a pretty pale yellow and it is very bright. The brooch fastens with a C catch and it is marked 800 on the catch (very hard to see).
It measures 1 5/8 inches by 1/2 inch and it is in very good condition. The silver has a dark patina that could be cleaned off if desired.
