Does anybody know of anyone/company that purchases quality vintage turquoise jewelry?
If you know the value of your items, you might try Facebook market place. Just meet the buyers at the police station and only accept cash.

I’ve bought from them, but not sold. They do re-sell, so don’t be disappointed if they don’t make an offer of full retail value.
Join some of the Native American jewelry groups. There are some good people with lots of knowledge. You can buy and sell. Ask for pointers, check out the moderators of the groups. In other words, do a little research so you are comfortable. Most use PayPal goods and services. It gives you some security.
