Mexican 925 Silver Round Ball Stud Earrings - Butterfly Back

Earrings are in Excellent Used Condition but have been in storage for some time and do have surfaces scratches as a result of age, wear, and storage. I've managed to shine these up but may have missed some spots. Earrings were handmade in Mexico meaning it lacks the precise cuts and angles as if it were made on a machine and favors uneven edges and finishes. Earrings are a Round Ball Stud Design with butterfly fasteners. However, I'm only able to locate a 925 on the butterfly backs and not the actual earrings. I do know the person for whom I'm selling this for and they do not wear consume jewelry, thus I know this to be either 925 or even 950 silver. However, I'm unable to reliability demonstrate that without the stamp. Thus, this earrings will be priced in the middle.

Please note I am selling this on behalf of another party and am therefore unable to be exceptionally flexible on offers.
