Get your remains pressed into a diamond -

Oh man, this is sweet. I am honestly considering having this done to my remains. ESPECIALLY if my freaky 'soul-gem' can then be affixed into a ring. How D&D is THAT!!?? I promise my descendeants to do my very best to haunt that gem and do freaky ghost things for the possessor of it. WooOOOoooOOO! Heh heh.
