This is an older ring, and likely wasn't made to sell. Instead, it was probably intended for the maker to wear—as it doesn't have a hallmark. Hallmarks are a selling aid that began in the 1930's and 40's. Given that the turquoise here still retains more a blue hue, and was buffed rather smooth by an electronic buffing tool, this ring was probably made in the 80's or 90's—thus cannot be considered true 'vintage.' True vintage pieces were made prior to the Dine's use of modern electric jewelry-making tools (prior to 1970). The ring has good weight to it, at 19-grams, or .63-ounces. It is 1 and 3/8th's-inches lengthwise across the face, and a little over an inch across at the widest point. This is quite a nice ring for the money.
