I have a silver & turquoise petit point ring by Zuni silversmith Tom Hannaweeka (stamped TAH) and wonder how valuable it is, if he is still alive, etc. Definitely made in 70's or early 80's. Thanks!

These are all I could find

Hi,
The bio on Thomas in Hallmarks Of The Southwest by Barton Wright is quite short. Zuni silversmith/lapidarist. Spouse is Alice Hannaweeke. Hallmark was first used in 1975 however they show his hallmark as T-A. H
Cheers, Norm

The link I posted said Tom and Sharon.
IDK?

If you are good with the Native American jewelry hope you stick around cause so many people ask about it and we really don't have anybody that knows.

Well stick around even if you aren't an expert in it. :D
