Pirate Glass Lucky Dip

Buy a little piece of Pirate Glass from the shores of the UK.
 
Pirate glass is seaglass that is so thick, that it looks black until you shine a light through it, revealing its true colour. You can read all about the details of Pirate Glass in this blog post I wrote about it. 
 
Recieve a random piece of Pirate Glass from my collection :)
