punch for silver jewellery

I made this punch from stainless steel for using on silver sheet for jewellery.
The photo shows its effect on pure aluminium.
I made it simply using a pocket and profile operation with HeeksCNC software on my Sieg KX1 milling machine. The design given to me was pencil on paper. I have noticed that the result is the mirror image of the design. I hope she doesn't mind! I can easily make another one the right way round.
