Mother-of-pearl shell with pearl white accents. These iridescent white beads come from the hard internal layer of the sea mollusk that produces pearls. These MOP beads are a vibrant white. The 10mm nonfaceted beads are accented on each side with copper bead caps and this stunning rosary is finished with a beautiful Mary center and a large pardon crucifix measuring 2 1/4 inches. Included is a velveteen bag with a handmade charm attached. All our rosaries come with a lifetime repair warranty.*** I recently change the centers on this rosary to a miraculous medal. If you receive a rosary with the old center I am glad to switch it out and cover postage.
