I’ve been doing copious amounts of research on NA jewelry and came across some videos that I feel like this community would really appreciate as much as I did. I compiled them into a youtube playlist and am leaving the link below! Please let me know what you think of them, I’d love the discussion! 
Glad you found them. I have watched several of his and enjoyed them.
@Islandmomma my two favorites hands down have to be the Ernie Lister and the Darryl Dean Begay! I was glued to my phone the entire time! 
Good overview. Thanks.
Now I know how to pronounce Eiteljorg Museum!

And Hogan is not Ho’ Gan…but Ho Gan’
You chose two good ones! Darryl Dean Begay even has buyers in Japan. He and his son Robert made a trip recently. Robert has become a great jeweler in his own right.
There are many more good ones for you to discover…and then there are the videos about the turquoise itself. Gene Waddell, John Hartman and many more. Happy learning!
