Vintage sterling silver rosary. The beads look and glow like some sort of feldspar stone with asterism. When tested with a gem tester the needle does not move which indicates likely glass. However some types of feldspar does this as well. Whatever these beads truly are, they are stunning. 

The opening of the rosary is 28" and the front piece is 6 1/2". The crucifix is 1 5/8". It weighs 23.6 grams.
