I recently started looking around on Pinterest. Russ, who also posts here is a keen 'pinner' of turquoise beads and jewelry. With 653 images of turquoise and native American jewelry, this is a bord that may interest you.

I have only bought 'turquoise' colored beads I know to be imitation pieces. Personally, I can tell the obvious fakes apart, but not the better fakes, treated or colored stones. It makes me weary of buying 'real turquoise'. Last year I did trade a necklace I made for three strands of beautiful turquoise beads in Tucson, straight from a miner.
