💥Mexican 950 sterling silver set💥

From what I can find, see photo, 950 silver is pre WWII but that may not be completely accurate as I’m relying solely on info from the internet. You can see the marks on the back of the necklace and on the back of one earring, both earrings are clip ons. There are stones that appear to be onyx or something very dark on the necklace and earrings, also a second metal that could be gold and or copper, no markings to tell. Definitely needs to be cleaned.
