Two Silver or Silver tone Necklace Pendants - One is a Starfish

I’m selling a Bundle of Two Silver or Silver Tone Necklace Pendants. One is silver colored with a blue stone and the starfish is silver colored with brown tones. I believe these are costume jewelry as I couldn’t find markings. I believe the blue stone is probably glass but I'm not positive. These have both been worn and loved and show all over wear including scratches, dents and other wear/ imperfections but they still have life left in them. This listing is for the pendants only and there isn’t a chain included. They would look great on a silver chain. Measurements are approximate and colors may be off because of lighting.
