Can anyone help me identify this crystal I found in a Wisconsin river? It is not scratched by quartz, the outside(polished surface) was scratched by a sapphire but the inside (broken surface) will not even scratch with a diamond sharpening file. It is slippery, cold, and heavy. The size is bigger than a quarter horizontally and vertically. Are there any tips besides asking my local asshole gem guy to determine the worth of this thing?
"Probably Just Quartz" comment was "Probably made by an Idiot". Without being checked by a knowing professional who will not just give you an answer without checking the true makeup of the stone is not a good answer. I went to the Mel Fisher Museum.... There was a million dollar emerald that I would have thought was a scratched green rock and would have used it as a pond skipper. To look at a stone and not have the expertise of knowing what it is could cost you a great deal of money. Remember the large emerald found at a flea market? How about the gold nugget being used as a door stop. Not knowing could make you feel pretty silly if you find out later that it was real....
