Turquoise and Sterling Bead Heishi Necklace

I had a chance last weekend to hit our local flea market...the last one of the season before the snow starts flying.

Found a great necklace I'm giving my Mom. It has graduated rolled turquoise beads with little sterling balls interspersed throughout. I got it for $15 and was thrilled. The lady had a 4 strand fetish for $20 that I should have snagged, and I didn't. They have a Christmas exhibit, so will track her down then in case she still has it.

It measures 18" in length. It appears there was a stone at one end of the clasp that has broken. The other one is intact. It's not marked, but my magnet has no interest in it.

Thanks for looking!
