Exquisitely fine filigree work in this white gold circle brooch, in a style typical of the early 1900s. Very refined workmanship, the tiny detail is a real delight. It extended to cover the entire surface of the pin and the sides too.
This circle brooch is 33mm in diameter or 1 5/16" in diameter. It is 2.5mm deep not including the pin stem.
It is unmarked, the original catch replaced by a modern one and the mark lost. It was carefully tested and it is in excellent condition. It weighs approximately 4 grams.
