I bought this amazing Nacozari turquoise stone from my friend Andy Brown of Cerrillos, New Mexico.  It comes from just over the border in Sonora, Mexico in an area famous for copper mining.  Unlike any other turquoise that I have ever seen, it also features shiny silvery pyrite that combines wonderfully with dark blue/green turquoise.  The bracelet is my unique design that allows the stone to perch on my "peninsula mount" bezel so the cuff can be easily adjusted to your wrist.
