Vintage Rosary with Blue Glass Beads

Vintage rosary with blue glass beads. The metal is silver, but not sterling. It is 28" long and the front is 7 1/2" long. Silver has tarnish and wear. 

If you plan to use this piece, please count the beads. Although I love and admire devotional jewelry and art, I am not Catholic and would not know if this piece is missing beads.
