Hello,
Looking for a value on this vintage hand made Zuni Cluster-work Turquoise Necklace set in Silver
I have what I’ve been told is a Zuni cluster-work necklace. Also have been told that it is hand made including chain and clasp, that each bezel is serrated by hand, dating it to 1940’s to 1950’s and manufactured bezels made an appearance in the 70’s.

There is some confusion about it’s worth or if above information is correct; opinions on this will be greatly appreciated. It is missing one stone which is around here somewhere.
Thank you very much!
