PT Bent Square Shank Hallmark Stamp-1/32" (0.75mm) Impression Height

This bent square shank PT hallmark stamp is crafted from precision-cut, heat-treated tool steel and is designed for marking precious metals with a clean, sunken impression. The bent shank — also known as a gooseneck design — allows access to curved or recessed surfaces, making it especially useful for stamping the inside of rings and other hard-to-reach areas.

The PT designation identifies this stamp as a platinum hallmark, essential for properly marking platinum work. With a 1/32" (0.75mm) impression height, this stamp delivers a precise, legible mark. Note that the measurement refers to the height of the impression, not the width.
