This a wonderful early Brooch. It has all the great swirling detail and a "T" bar and "C" clasp closure. The pin is in excellent Estate condition. It is 3.9 grams of 14 K gold acid tested for fineness. The Brooch is 1 3/8" by 1".
But I think the thing that especially sets this Brooch a part from the rest is that it is in Yellow and Green Gold. Green Gold is the rarest form of Gold.
I did not clean this piece on purpose so you could see the patina. A great genuine Brooch for your collection.
