Here is a 1/20 12K G.F. etched bangle made by Kestenmade in the US. It is not completely round in shape but slightly oval. On the front is an etched flower with leaves. The bracelet opens by pulling it apart. It is stamped Kestenmade 1/20 12K GF US. It is 1/2" wide and the opening diameter is 2 1/16" X 2 3/8". Closes tightly with a clicking sound. Very nice condition with slight wear on the edges.
