750 (18ct) Curved Carat Hallmark Stamp

750 (18ct) Curved Carat Jewellery Hallmark Stamp Punch

This quality 750 German-made carat stamp is .75mm high. This is the hallmark you need to use for 18ct gold (an alloy of 75% gold and 25% other metals).

This carat stamp is curved so you can hallmark the inside of rings, as well as any other piece of jewellery that requires a hallmark. 

The engraving is slightly arched to follow the shape of the ring and the curved shape makes it possible to punch directly into rings.
