VTG Estate 3 Piece Ornate Metal Glass Vase Holders Rare Sterling Silver Plated? For Sale

These were from my mother-in-law‘s estate sale. I am not sure if they are silver plated I can’t find any markings. She use them for vases. There is some scratches on some of the glasses inside no chips. The silver plating is not in perfect shape, but I did try to clean them. Up of magnet did not stick to them, I would assume that these are probably silver plated not silver but I’m selling as just metal since I’m unsure. Absolutely beautiful and gorgeous for any table setting selling as please go over all photographs and measurements. Thanks so much. Measurements are in the photos.
