We have a lot of 3 stone pendants. They were mixed in with a lot of vintage jewelry - I don't know if they are vintage or not, either way they are very pretty. The purple one is wrapped in a silver tone metal and measures about 1 3/8" x 5/8", the black one is about 1 1/8" x 5/8" and the beige one has a gold tone metal top is about 5/8" x 3/8". I don't know what type of stones these are. They are in good gently worn condition.
