Fred Gurerro vintage sterling silver and turquoise ring

vintage hand wrought Navajo ring that features a perfect stone from the Bisbee mine in Arizona. I encourage anyone who is a serious collector of world class American turquoise to research the qualities of high grade...gem grade..Bisbee turquoise. Examples this nice are impossible to find and rarely available. They end up in private collections and museums.The blue in this stone is as blue as Bisbee can get and referred to as high blue. The matrix is webbed. Webbed matrix is the most sought after matrix with collectors of natural turquoise. Some Bisbee won't have any webbing, just a scattered matrix. This stone displays a perfect balance between high grade turquoise and high grade webbing, showing equal amounts of both. So a lot of precious webbing, precious blue color and an equal balance of both. Really outstanding. Red matrix is not, of course, a true cherry red. But that is what it is called. It's more the shade of warm orangey brown butterscotch.
