Time to make a blood sacrifice to the lapidary gods, that is!
Every so often, as you may know, the lapidary gods require a... token of your seriousnessitude towards the craft. Otherwise, all your hard work and practice will do you absolutely no good whatsoever - all your rocks will crack, your dop sticks will break, your polishing jobs all orange-peel and don't shine up... it's an absolute nightmare.
That's actually just residue leftover from working on my cobra script jasper, over there on the right. It sure is a pretty stone, but daaaaang is it messy to work it.
(At least it's just messy and not messy AND stinky, which would just be trouble.)
Anyway, there are many stones that grind relatively clean, but then there are also many stones that are just... nasty. It's kind of fun to see what colour the mud at the bottom of my Genie turns into at the end of the day, though...
PS - lapidary gods, if you do exist, you rock, no pun intended. Oh, who am I kidding, it was totally intended. Please don't smite me. :-D
