Nativer American belts

As a British man, I have always greatly admired Native American culture and I would be interested in acquiring a genuine Native American belt which wasn't tourist kitsch and was appropriate in design/patterns/colours/stones and metals for a 50 year old male.

Can any of you point me towards articles, books, websites that would help me search for something authentic?

I would be interested in Native American rings meeting the same criteria as well.

Thanks in advance chaps.

Have you spent some time on this thread?

There are some nice belts (most buckles rather than concho belts) shown here.
