I bought these at an estate auction and I am wondering what they are. They say Made in Mexico - in Spanish on the back and 925 and three letters that I believe are PHC. They also have a circular stamp with a line in it. They measure about 3 1/4 x 2 1/2" and 2 3/4" x 2"
The second picture shows a pendant that is around 1 1/2" in diameter and simply says Mexico on the back. Thank you for any help!
