Having lived on the Navajo reservation in northern Arizona, I can tell you that there is plenty of turquoise jewelry to find exactly what you wanted.
I lived on school housing as I taught for the local school district, and the locals would always come through the teacher housing trying to sell their crafts, mostly jewelry. As we lived near the Hopi reservation, we would go to some of the Hopi bazaars looking for locally made crafts, too.
My wife had purchased a very nice turquoise bracelet during the week, one month, we went to the Hopi bazaar that weekend. One of the Hopi jewelry dealers that we got to know noticed it, and asked my wife how much she had paid for it. On closer inspection, she pointed out that it was fake turquoise!! She explained to my wife and I that real turquoise doesn't burn when a red hot nail or pin is put directly on the turquoise, so just be aware that fake stuff exists.
If the dealer is reputable, they should let you heat up a pin, and press it to the stone.
