A Peltier Blue Panther, usually with a very light amount of very fine aventurine, appreciation for the photo given to the "Peltier Marbles Information Site" Wish you had one William as I wish I did also, VVHTF I've never even seen one to my knowledge except in pictures. I think this one belongs to Sami Arim, at least it bears a close resemblance to his personal example of the one in his book ??
