14K Bent Square Shank Hallmark Stamps-3 Sizes

These bent square shank 14K hallmark stamps are purpose-built for marking precious metals with precision and consistency. Crafted from heat-treated tool steel with precision cutting, they produce clean, sunken impressions ideal for karat identification. The bent shank design — also known as a gooseneck style — allows access to the inside of rings and other curved or hard-to-reach surfaces where a straight stamp cannot reach. Made in the USA and Germany, these stamps are a reliable professional tool for jewelers and metalsmiths working with precious metals.

Note: Measurement refers to the height of the impression, not the width.
