Welcome Allisong and Kraez70 nice to have you here at MUT I am Joy. Kraez70 the info you posted has me a bit concerned for many years I have been able to take 10 and 14kt gold jewlery and rub it on any part of my skin and leave a black mark. I can draw on myself with jewlery, I have used it in the past to take down phone #'s when I did not have a pen and paper. Myself, friends and family have always wondered why I could do this. Now I am kind of worried it, I wonder if I should have my blood checked for lead or something I have also been quite ill with Lupus for 17 years, your post has me wondering if there might be some connection. Hmmmmmm
