Vintage best Made SW American Vein Turquoise & Copper Necklace

Newly made necklace of American turquoise natural veins. Much of it is from the Sleeping Beauty mine, but you can tell it was dyed because the natural white veins are black. And, it was stabilized only to keep the edges from chipping. The necklace is 23 inches long and closes with a lobster clasp. It's a real stunner.
