Rare find! Vintage 1940s/1950s. Large goldtone bow with beautiful aquamarine blue colored crystal stone. This bold brooch measures 3-1/2" wide, 1-3/4" tall and 1/2" deep. The clear blue prong set stone measures 1" by 3/4". It has a 1-3/4" pinbar with rollover clasp. Weighs 47.2g. Quality workmanship, but unsigned. It does have some minor chips in the plating that can be seen under magnification, but is otherwise in very good vintage condition. A gorgeous addition for a wedding sash or a lovely gift for that March birthday.
