i agree with your thoughts about the black woven beads. i have had them a long time and got them from an estate sale so i am guessin mid-1900s as well. i think they could be silk but since i have so few i have not wanted to subject to any "tests". they are about 6 x 10mm with a 3mm hole. they are really quite fine and somewhat of a marvel to look at and hold.

thanks for the info,
