Royston turquoise has become quite sought-after and a lot more expensive than it used to be. That's one reason you see so many offerings on the internet labeled as Royston when it is not. It certainly has alluring, dreamy hues. Here it is used simply as a stand-alone stone sitting atop a highly textured Sterling band, and the result is an eye-catching cuff that oozes quality. The total inside circumference—including the 'gap'—is 6 and 5/8th's-inches, which is sort of an average woman's wrist size (maybe leaning toward medium large). It's pretty stout so it will adjust very little if any. The buyer needs to have a wrist measurement completely around the wrist bone of 6.5 to 6.75-inches. The band is 7/8th's-inches throughout, but the stone and bezel is 1 and 5/8th's-inches across lengthwise. Weight is a respectable 88-grams, or 3.1-ounces. Hallmarked "MC." Matthew Charlie used an "MC" hallmark before going to his full name instead. Also, Mary Chavez uses an "MC" hallmark. We're going to chase down the source and clarify it here.
