These are delicate gold over silver threader earrings. They are marked, but it is very hard to read. I can make out a "China" and "925". There is another very small mark that I can't read. The stones could be gemstones, glass, or crystal. I am not sure what the stones are, but they are beautiful, possibly topaz or aquamarine?  These earrings are pre-owned in very good condition. Please see the photos and item details for more specifics. Feel free to message me with any questions. Thank you.
