Do gallstones smell like boo-boo?

Hi all, after awaking today very nauseous (drinking wwater cleared out the nausea and olive oil taste though) I've had some diarrea and lo and behold, green polyhedral floating stones, from the size of a pin head to the size of a marble..

I saved the largest one and upon examining it it smells just like feces - is this accurate or do Gallstones have a different smell?

thanks
