925 (Sterling Silver) Curved Carat Hallmark Stamp Punch
This item is currently on its way from Germany and is expected to arrive in mid-August. It is available for preorder and will be posted to you when it arrives in stock.
This quality 925 German-made carat stamp is .75mm high. This is the hallmark you need to use for sterling silver (an alloy of 92.5% silver and 7.5% copper).
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.
