Yeah Haven's site is also really good. Not just for pure e-commerce reasons (measurements, pics, etc), but editorials. The nonnative bangles look nice in a wear-with-Visvim kinda way. I'm guessing still expensive relative to "authetic" Navajo and other jewelry. Pretty good pricing on DRKSHDW and other stuff too.
Like, a bazillion times more expensive, given what you are getting. What companies like nonnative do are "curate" those pieces for you and present them nicely. But you can go to reservations in AZ or some other states, or go online to some pretty ramshackle shopify store, and get the same or better for a lot less - about 1/3 of of the price, often, if that. If you are really into that look, go to a place like this: http://www.indiantraders.com/store/Native-American-Jewelry.html, and you'll see comparable sterling stuff selling for as low as $150, and topping out at often under a grand for a ton of silver, turquoise, and workmanship. The stuff from Japan has an interesting feel though, in that it's specifically NON-authentic. It's a very Japanese take on a very American tradition, non unlike, say, how Snowpeak takes American and European mountainclimbing and outdoors pursuits, and spins it on its head. Is it more functional? Highly debatable to a hard "No". Really cool and unique - a definitely yes.
