Necklace Rare Vintage Slim Lamp Work 17 ins

This is very special. It is in fact, difficult to make such slim long glass beads. I have owned them in a bag for about 30 years. And now, a necklace. No metals except the Sterling Silver clasp. Knots to protect the thin ends of each bead, keeping each one nested it the knots and safe. Eye catching and rare, very rare. I believe I may be the only one anywhere who has these vintage slinky glass beads! The necklace is 17 inches long. It takes someone who knows glass perhaps to see how special this is..
