This is a prayer or worry bead necklace. The beads are made of camel bone and inlaid with sterling silver and turquoise. The beads are very intricate. Each bead measures about 1/2 of an inch long. The necklace has a clasp marked SILVER. There are 17 beads on one side of the clasp and 16 on the other. There is a long carved shank with three coins dangling from chains. The necklace measures 16 inches long. The shank and coin portion measures 4-1/2 inches long. It weighs 48 grams. This is my limited information on these beautiful beads. I believe they would be a wonderful tool for meditation. Please feel free to contact me with questions. Thanks for stopping by.
