Three Marquise Light Green Gemstones Drop Earrings

Three Marquise Light Green Gemstones Drop Earrings I only wore these once. Got these sweet earring at a small boutiquw many years ago. I think they might be vintage. I do not know what the gemstones but based on the place I brought it from I would assume the gemstone is real. There is a small stamp that I think says "925" meaning the hardware is silver, but I do not know for sure. (see last photo, the stamp is really small)
