I have these two "crumb" beads, and would like the opinions of the bead cognoscenti, please-

I think the one on the left with the black base is probably Indian.

The one with white base - is it Venetian, Czech, Japanese or Chinese? Or another Indian?

The surface inside the hole of the black bead is rough; for the white one, it is smooth.

Both beads are about 13 mm diameter. The black bead has a 3 mm hole; for the white bead it's about 1.5 mm.

Thanks!
