I really cannot tell you anything about these other than the beads are either glass or a natural stone like onyx but not sure of that. The beads are all about 9-10mm in size. There is a great deal of circular mottling in each bead. There are two stamped out silvertone medallions dangling form the piece. These are identical and depict a laurel leaf design around the outside center with a star at the top and then I have no idea. These maybe Middle Eastern prayer beads but no proof of that. The piece is about 13-1/2"long to the bottom of the medallions. The metal is all silver or silvertone in the medallions. This is in excellent condition.
