VTG Circle Brooch

This is an unusual and beautiful circle pin that has been in our family for many years. It's a fairly heavy piece at about 27 grams but has no markings I could find. The jewels all look to be top notch and in wonderful shape. Likely from the 1950's, it has been carefully stored for many years but deserves to be worn again! It's about 1 3/4" in circumference with gold tone metal.
