These very vintage earrings have screwbacks. They are loops of metal rope. Sort of look like knots or bows with a flower set with yellow faceted stones in each petal and center.
The earrings are marked on the screws Sterling. Once on one screw and twice on the other. One looks like a replacement screw and is lacking the rose gold color of the other.
The earrings seem to have been given a rose gold wash over the sterling. This is in the tradition of Bond Boyd Sterling jewelry although this is not marked Bond Boyd. The earrings are 1.5 inches top to bottom and other than the replaced screw, which is firmly soddered on, are in excellent vintage condition.
