Maui, I took what I believed was a piece or coral. Call me superstitious, but since taking that rock or coral...I have been very ill. I have managed to develop pneumonia which kept me out of work for weeks then it developed into a bronchial infection. I don't want to take chances, but how can I return this stone if I can't get back to maui? Is it alright to return it here to the beach on Oahu? Help.
