This breathtaking 20.5" Yemeni prayer necklace is made from Yemeni black coral prayer beads with silver inlay. There are four accent beads of pink coral as well. All beads are in excellent condition with a consistent silver inlay pattern on all black coral beads. The average black coral bead measures 12.5 long mm x 7.5 mm in diameter. The longest black coral bead (near what would be the tassel) is 44 mm long x 10.5 mm in diameter.
