Vintage Rosary, Sapphire Blue & Black Beads, Ave Maria, Crucifix,

Religious, Catholic rosary with light blue & black beads, Crucifix Pendant, Jesus Christ. Looks like Mary adorns the front and perhaps a Saint on the back. They are too small for me to make out but perhaps you know who they are. The rosary measures 5.5" total length. It's quite lovely, but I don't know much about them so I hope you find the price fair. If you can add or correct any information please do so in the comments, ty!
