Authentic turquoise and silver Indian style jewelry?

I'm looking for some pretty, turquoise stone jewelry, perferably in silver settings. Where can I find necklaces and cuffs that won't break the bank but are of good quality? I'm looking for something Aztec, Indian style but I don't want anything too literal. To get a general idea of what I like, Miley Cyrus wears this necklace a lot: http://www.myjewelrytrends.com/wp-content/uploads/2010/07/13/Miley-Cyrus-Turquoise-Necklace.jpg. I've been on Etsy but there is so much to weed through! Anyone know of SPECIFIC SELLERS OR SITES that sell jewelry like this? For a 19 year old.
