Old Mexican Handmade Sterling Silver "Pearls" Bead Necklace

Old Mexican sterling silver necklace of hand made and soldered bench beads or silver pearls. The beads are graduated in size from 5.9mm to 11.8mm. These beads were hand soldered and the holes were hand punched from the inside out. See close up shot. Weight: 12.8 grams. The clasp is well hallmarked and is non-locking. Beads are tarnished and a couple have shallow and small dents. Beads are on chain. There is a gap in the beads at the back because the chain stretched. Good early one. These are getting to be so hard to find.15 1/2" long.
