SOLD! The Kingman, Arizona turquoise mine has been consistently producing high quality turquoise for decades and decades. It was "the" turquoise back in the 60's and 70's. Since then, when a vein with a certain look would play-out, the huge mine would reveal other veins of equal beauty and relevance. There is a Youtube video of a tour of the Kingman mine available online. Here, the earrings above have hand-picked Kingman stones that exude what turquoise is all about. Length is 1 and 1/8th-inches, and are a little over 3/8th's-inches at the widest point. Weight of each is 6-grams, or .21-ounces. Hallmarked, and always complimentary Priority shipping within the U.S.
