CZECH Glass Beads - Lighting ? or what ???

Smaller CZECH Glass beads as Marked. Not sure if it was for a small lamp or what. They are broken as they were found in an old box here, and of course, I did not throw them away ( never, never....LOL ). Anyone know what they were for. I have seen these type for lamps, but this is smaller -- so not sure.

For a Small lamp -- or what ??

Thanks for your help!! Luvs.....
