14k rosey yellow gold signet ring with ribbed lines. The blank area for engraving measures about 5/8" wide by 1/2" tall. The ring fits a size 6.5 finger and weighs 5.11 dwt. The ring is smooth on the underside for comfort. It is an eternity design which would be difficult to size without interrupting the lines/ridges. It dates from the 1940s. Wonderful!
