What is this ? Found on old tobacco farm

[Broadleaf]

I restore old tobacco barns for a living and found these 2 items on 2 different days in the footings of a tobacco barn about 2ft down in the soil.. I wanna say it's early native American jewelry or something similar.. I have been looking into them for a while now with absolute no results.. taken them to multiple antique stores and no help.. please reply if you know anything at all about them.. I believe them to be mother of pearl with sunflower seeds in them.. please help

I don't know what they are. Photo isn't clear enough to tell. I have been in the rails of many a tobacco barn myself, back in the day hanging burley.
