10K Bent Square Shank Hallmark Stamps-3 Sizes

These bent square shank 10K hallmark stamps are made of precision-cut, heat-treated tool steel and are designed for marking gold alloys that are no less than 0.375% pure gold by weight. The bent shank design — also known as a gooseneck stamp — allows the stamp to reach the inside of rings and other curved surfaces where a straight shank cannot access. These stamps produce sunken impressions on precious metals. Measurement refers to the height of the impression, not the width.
