Vintage silver teardrop cameo pendant necklace

Vintage Silver Necklace -This piece is really unique! -I believe it’s either silver or silver plated, but I don’t see a identifying marking anywhere on it -When I bought it, it was heavily tarnished and dark gray, -I polished it with a silver polishing cloth and it looks amazing now -The cameo in the center appears to be carved from hematite -There’s a cute filigree design at the top -It’s in excellent condition -If you buy this item, I’ll include a new jewelry polishing cloth with it so you can keep it bright and sparkling!
