The Drifter almost never buys adjustable rings. That's because most of the time they are flimsy tourist gimmicks. This ring is the antithesis of that. It's heavy (21-grams, or .74-ounces); it's very well-made, and it has a knock-out turquoise stone—probably one of the Kingman varieties. The adjustable shank of the ring is much thicker than the adjustable ones usually encountered. It might not lend itself to adjusting more than a size and-one-half either way. It is currently size nine. But if you have size 8 through 10, it will easily adjust to your size. It is 1.75-inches long and a little over 7/8th-inches at the widest point, and, It is hallmarked. This is a really nice ring. Always complimentary Priority shipping within the U.S.
