Gray pearls rose gold tone screw earrings grape clusters with leaves vintage ll2626

An unusual but lovely pair of vintage earrings made in the shape of a bunch of grapes. The grapes are 6 gray pearls, may be cultured, and the leaves are rose gold tone metal. The earrings have screwbacks and measure 1 inch in length. These are not marked which surprises me as they are really nice both in quality and condition. Slight finish wear to the back of one but these are about 60-70 years old.
