Unique art required!! Based on a really ugly shell that I'll provide :)

First time using this site and a bit of a strange job for everyone. When my fiancé and I first started dating, I picked up a shell on a beach we were walking on and jokingly asked her to marry me. We laughed because the shell I'd chosen was super ugly, scratched, beaten up etc. I couldn't have picked up a less attractive shell! Secretly I kept that shell, and now we are engaged for real I want to make something special from it to present to her on our wedding day! I'm thinking setting it in some form of highly polished resin - like an old paper weight maybe, presenting it in a wooden jewelry box that can be displayed on a shelf open, maybe with some burnt engraved lettering into it of the date of our wedding. I'm not a skilled artist and these are just initial thoughts, so I'd like someone to use their imagination, take the shell and create something fantastic! Photos of the shell are attached, one against my mac keyboard so you can see the scale - its about 3cm across and 2cm deep - I would like the scratched surface of the shell displayed upwards please as its what my fiancé will recognize!
