Antique 23″ round Whitby Jet beads

Stunning example of long Victorian Whitby Jet beads. They are graduated 9mm -18mm in diameter. One bead has a crack, probable representing a flaw in the rough jet piece. It is stable and doesn’t detract from the beauty and appeal mod the beads. I believe they have been restrung and the original carabina hook catch is in working order.
