Vintage Sterling Silver Disco Ball Bead Necklace Silver Pearls

Vintage sterling silver beaded necklace. These are typically called silver pearls, but these beads are "disco ball" beads that shimmer in the light. They are hand made and the holes were hand punched and not machined.  

Beads are graduated from 4.5 mm to 12mm. (Measured with caliper) Necklace is 26" long. Has hidden locking clasp. 

Beads are on chain. Need to be polished. Super pretty! Hallmarked near the clasp Sterling and with a conjoined HE.
