costume jewelry #5, whitish organic (?) beads

With what I've learned in the past 24hrs about the blue/white "Job's Tears" beads, I gotta guess these are some close-ish variation of the same kinda thing. (??) THANKS for the edjumcation about those by the way, to my CW friends!! :-)

This string is roughly 31" long (when hung from something, thus doubled) and is threaded onto a red woven string. The beads are all irregularly shaped and mostly uniformly ivory-ish colored, each about 1/4-3/8". Once more, the whole thing isn't nearly heavy enough for it to be made of anything 'solid'...???
