THIS IS AN AWESOME OLD AFRICAN TRADE BEAD NECKLACE WITH WHAT LOOKS LIKE ONE LARGE GLASS BEAD CENTERED THAT MEASURES 1 1/4 INCH BY ABOUT 1 INCH. IT HAS 20 AGATE CARNELIAN BEADS AND MAYBE GLASS OR TURQUOISE? SPACER BEADS. STERLING SILVER CLASP. IT'S OLD BUT I'M NOT SURE HOW OLD. IT'S EXTREMELY BEAUTIFUL AND 31 INCHES LONG.
