What a beautiful ring! The turquoise has a greenish-enough tint to be from the Royston Mine, but there is just enough blue traces for me to think it is a colorful vein of Kingman turquoise. The turquoise is stunning, but so is the silver-smithing surrounding the ring. It's the type of silverwork that might usually be employed on a very expensive large lariat necklace. And the bezeling is done with a time-consuming-to-make sawtooth construction. It is a size 8, but you'll notice in the last pic that the nice double-wide band is made to adjust somewhat. It doesn't appear to be able to go much smaller, but it will probably go a size or two larger. The face of the ring is 1.75-inches long, and an inch and one-eighth wide. Weight is 18.5-grams, or .65-ounces. Hallmarked. Complimentary USPS Priority shipping within the U.S.
