A very pretty string of lovely quality blue star glass chevron beads with deep blue glass beads  in between.   I think these glass beads are most likely made in india.  They are on contemporary tiger tail thread and have a modern clasp.   Just beautiful.  Dont hesitate to ask any questions.

Wiki Info:  Chevron beads are special glass beads; the first specimens of this type were created by glass bead makers in Venice and Murano, Italy, toward the end of the 14th century. They may also be referred to as rosetta, or star beads. The term rosetta first appeared in the inventory of the Barovier Glass works in Murano, in 1496, in context with beads as well as with other glass objects.
