ANA 1405 Sonoran Gold Turquoise heavy stamped ring

Sonoran Blue Gold Canyon Turquoise is an interesting turquoise from Senora, Mexico, near Nogales, Arizona, and its neighbor: Nogales, Mexico, which is the northernmost point in all of Mexico. The series of mines bearing this name are on several sites contingent to the American border. Very little hard natural material has been mined here. Most has needed stabilizing to be useful. The high-grade natural material is a medium blue, with darker blue matrix, forming a "birds’ eye" pattern. This is usually accompanied by iron pyrite, giving it a similar look to a high-grade Morenci. The high-grade turquoise from this mine is rare and is considered both esoteric and valuable. Beautiful Sonoran gold Turquoise ring. Crafted by Navajo artist E.M. linkin. Set in solid sterling silver with a signature style heavy stamping surrounding the stone. The large setting measures 1"3/8 x 1" with the oval stone measuring 1" x 1/2". The blue-green coloring of the turquoise make this piece a stunning addition to any collection.
