This bent square shank 585 hallmark stamp is made of precision-cut, heat-treated tool steel and is designed for marking precious metals with a clean, sunken impression. The bent shank — also referred to as a gooseneck stamp — allows access to the inside of rings and other curved or recessed surfaces where a straight stamp cannot reach. The 585 designation marks gold alloys of 58.5% purity (14 karat), making this stamp an essential tool for jewelers who hallmark their own work.
