I have 220 of these lovely glass black faceted barrel shaped beads. They are of various sizes, some with white accents. Most of them are about 1/2" long.
These were part of a huge lot of vintage jewelry and beads from an estate. I do not know if they are Czech beads or not. The camera makes them look like they are dirty or scratched, but the don't look like that with the naked eye. They are beautiful beads.
