Thank you for your reply but they were brought back for my great grandmother by her sons , my family has been doing some digging of their own ,
This is Australia. Army , so deferent places and time line
I inherited these pearls they are ny grandmothers
They were broken and re strung but not amazingly done the clasp has JKA 925 on it
My mother said my grandfather brought these for my grandmother during the war
I’m just trying to figure out how old they are what year roughly
Thank you
