EUC beaded stone multistrand adj necklace

really pretty great condition preloved silvertone stone, maybe glass?, beaded necklace with 3 layering strands. I am not a gem expert but I put close ups to show why I think they are probably dyed stones. they don't feel like plastic, they do appear dyed, the round stones look like calcite? I am learning as I go. please see pictures for details and measurements and condition other items are display only adjustable length.
