'Just got back from Navajoland with these treasures. Turquoise from the Royston, Nevada mine is very expensive now, which is likely why it's not used as much as it once was. These are real showpieces, with a swath of polished copper ore on either side of each stone. Those pretty stones are complimented by expert silversmithing by the well-known artist. They are a tiny bit over 1 and 5/8th's-inches long, and they are 7/8th's-inches wide. Weight is 10.5-grams, or .37-ounces. Hallmarked "M. Thomas, Jr." Complimentary USPS Priority shipping within the U.S.
