hello Ann- i have beads like this one.
i think they are Japanese but not Ojime -the core may be a fired ceramic bead, then covered with coloured lacquer layers that may be pressed into a mould, or carved, or both, and then the rather wide hole is strengthened with a metal "ferrule" so it can slide up and down without wearing away too much. yours looks like a black or dark green layer over red.
the design - shown upside down? may contribute to the value and slightly looks like its ocean waves with perhaps a dragon or a fish?
possibly up to 1930s? some interest and value because they were not mass-produced in large quantities, otherwise we would have seen more.
