This 18K gold late 19th century pin is of the most exquisite quality and workmanship. It is of the Belle Epoque time period when extravagance and beauty were prized and enjoyed by the nouveau riche. This pin has the eagle head indicating 18K gold (I have also tested it) and there is another touch mark I can not read they are stamped on the original "C" clasp. The piece weighs 5 grams and measures 3/4 inch by 1 1/4 inches. The delicate petals are enameled in pink on one side and blue on the other with only minor flakes (visible only through a loupe) and they are centered with a lustrous seed pearl.
