Adjustable Ring is silver plated stainless steel with black center stone. This ring easily stretches, so it will fit on a wide range of finger sizes. It sits at about a medium size (7.0). Ring is just shy of 1/2 inches wide. A nice lightweight ring to wear with my adjustable cuff bracelets. The adjustable size makes it a perfect gift choice. Customers will love them for themselves because there are so many woman with larger knuckles from arthritis that have a hard time finding fun rings.
