I found this seashell at St Mildreds Bay in Westgate and it was tiny and perfect for making a mould and a very simple pendant.
 
This is made from silver metal clay which is pushed into the mould I made from the shell and then left to dry for 24 hours before being removed from the mould and sanded. Once sanded it is fired in my kiln leaving 99.9% fine silver. I then soldered a jump ring to the top of it before tumbling it in my tumbler to harden the silver. 
 
I have then used a solution of liver of sulphur to add a patina before polishing it back to allow the detail to really show up.
 
The pendant is approx 20mm from the top of the jump ring to the end of the point and is strung from a 18 inch chain.
