Heishi anyone?

I still have a hard time evaluating heishi. These two seem to be good quality to me. They were among my first purchases of turquoise at an estate sale a couple of years ago. I would appreciate any info on age, type, where from, and how much they might be worth? Thanks!


These are both very nice necklaces. Age is always difficult, from the style and construction I think 1970s-80s. The first necklace looks to be serpentine with turquoise and I would say $450ish. The second I imagine is clam shell with turquoise $350ish. Nice find.

Thank you so much Jason!
