Antique 925 Sterling Silver Mother Pearl Shell Turtle Necklace Choker Handmade

Charming turtle pendant on a hand beaded necklace. The turtle's shell is made of a polished mother of pearl gem. Liquid Silver tube beads with other beads that seem to be brass, but I am unsure. The pendant is made of sterling silver and mother of pearl. Barrel clasp. Unmarked. Some patina to all the beads and clasp, but still in great condition. Pendant measures ½"×⅞" and necklace measures 16". Questions and offers are welcomed:)
