Description
These 18K bent square shank hallmark stamps are precision-cut from heat-treated tool steel and designed for marking precious metals. The bent shank — also known as a gooseneck design — allows jewelers to reach the inside of rings and other curved surfaces where a straight stamp cannot make contact. These stamps produce clean, sunken impressions and are manufactured in the USA and Germany.
Note: Measurement refers to the height of the impression, not the width.
