This is such a pretty brooch. It is a beautifully chased, with feathers, 10K gold case with a carved Carnelian stone ringed in Seed Pearls. It is 1 9/16" by 1 3/8" and weighs 10.3 grams.
The back shows some wear but has a "T" bar and "C" clasp in good working order. Someone over the years scratched 10K in the back, but it also has been acid tested to guarantee its fineness.
Delicate with a lovely patina, a wonderful authentic early brooch.
