the blue love stone has somewhat captured my interest, despite that I'm not apart of that general sub story. Generally because I've always was fascinated by magical stones or treasures for the most part of my life.
I wish to make a note of interest that there are such treasures out there, though they were spelled and manipulated through occultic covens (Wiccan, Pegan magick). Love stones, wealth stones, wish stones, etc, etc
and those who believe in that type of thing say that when in possession of such devices (if it is the real thing), they can feel a strange warmth or heat coming from it, or it made them dizzy or queezy while holding it.
So in all, you seem to be going in the right direction with the 'sick' feeling in connection to touching the blue love stone.
Just a thought of interest
