Recently purchased at an estate we acquired this old Bar Pin. It is circa 1930's and is trademarked Sterling R R. (which after researching we found was Ralfe Rings Jewelry)....who manufactured jewelry in the 1920's and the 1930's. We do not know anything about the stones except the colors which are red and clear in color alternate rhinestones.
A lovely old bar pin over 80 years old - Weighs 2.9 grams.
It is a beautiful old piece and surely will be treasured by someone.
It measures 2 5/8 inches in length.
