I remember this place now - I had forgotten. I actually emailed them a few months ago regarding this cuff that they claim is by Charlie John. I questioned them, because they had him listed as being Zuni, and this work IMO doesn’t look like his (I have a cuff by him). Plus the hallmark is off. They gave me some roundabout answer, insisting there are 2 Charlie John’s 
They changed the affiliation to Navajo, but I don’t trust them. I was going to ask members here if they were familiar with this business, and never remembered to; I think I know enough now.
Edit: when I asked them why they had him listed as Zuni when he’s Navajo, they said well, sometimes it’s hard to keep things straight when you have this much stuff on your site, or something like that. 
Apparently we have discussed them previously, and I forgot…Hallmark identification - is this native?
