Sterling Silver Screw Back Earrings with Bumpy Fresh Water Pearl Drops

Vintage sterling silver screw back earrings. Each has a lumpy, bumpy fresh water pearl drop. One has a large bump that appears to be glued in place, but it was not. The yellow around the base just needs to be cleaned away. This is the natural shape of the pearl. 

Earrings are marked silver and test sterling. Screws work well. Measure 3/4" long. Weight together is 3.4 grams.
