Necklace with light green multi faceted 'stones'

Light green 'stones' (I think it is a costume jewelry piece). Unsure of what metal the links are made of, but a bronzed color. Some small flaws, but they rub off. Please compare pics 4 (before rub) and 5 (after rub). I'm mentioning it because I will clean it, but if I miss any spots they should rub off easily. Offers welcome, especially if bundled with other items. Thank you!
