Beads: Ribbed “lantern” or fluted metal beads in a silver-tone finish.

* Centerpiece: The Blessed Virgin Mary praying on the front, with a Sacred Heart image on the reverse.

* Crucifix: A simple Latin cross with a darker silver-tone corpus attached by rivets. The INRI plaque is present.

* Length: Approximately 19–20 inches overall from your ruler photo.

* Material: Most likely silver-plated pot metal or nickel silver. I don’t see any indications that it is sterling silver from these photos.
