Sterling Silver 925 Post Square Possibly Peridot Earrings

Sterling Silver 925 Post Square Possibly Peridot Earrings. These are very pretty and I purchased new many years ago. I don’t wear them very often so I’m selling. I was told they were Peridot when I purchased but I can’t guarantee they are real since I never had them appraised. They are very pretty and I feel they go nicely with a Pendant I have listed as well. They are used and show all over wear. I believe the posts are marked 925 but it’s very small. I’m not sure if the backs are original and if they are Sterling or not or if they match each other or not. Measurements are approximate and colors may be off because of lighting. Since these aren’t new and have been used there may be imperfections.
