Antique Sterling silver Marcasite Drop earrings

Antique Sterling silver Marcasite Drop earrings Stamped 925 I purchased these myself from a very well known vintage & antique jewelry store in Seattle I used to work at. I don’t have the original backs anymore and one of the posts has a very slight bend in it, but I actually bought them that way. I know sterling and marcasire jewelry isn’t super hard to come by, but these are quite old and have a greater value because they aren’t just from TJ max; they have history. These are so beautiful! Hope they go to a good home, I developed an allergy to all my sterling silver jewelry after having my baby. 😩
