Wisconsin Diamond?

[luyluy]

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?

That is definitely an odd rock, I would have it checked. Could be a diamond, they have been found before here in Michigan. Carried down from Canada in the glacial drift. Good luck!

Interesting....VERY....Interesting!

Can it scratch glass? Like, say the mirror in your bathroom? Actually, quartz can scratch glass as well, just seeing if you read all of my response to your post. Bring to a good reliable jeweler.

It's one of those crystal skulls from the last Indiana Jones flick.

But, seriously, looks interesting.

A more reliable test would to be check weather it will scratch the windshield of your car. And then to double check, see if will scratch your rear-view mirror. Then drive to a reliable jeweler.
More seriously, that's a neat item. Welcome to TreasureNet!

Yes it scratches my windshield thats the first thing I did when I found it. Quartz crystal I found will not scratch it either.

The glacier diamond is no joke and few people today even know about them.

Your stone looks to have possibilities so get it checked.

I have no doubt that giant super valuable diamonds have been found and then thrown away because the finder thought it was common quartz.

When I was a kid we used to hunt for Michigan's Petoskey stone and sometimes we'd find these super shiny glass-like small stones. We just pitched them because we were told they were worthless quartz. Probably some were glacier diamonds because they are known to be somewhat plentiful in the Great Lakes States region.

See, they were brought down by the glaciers from some mother lode up in Canada. To this day they have not found that mother lode. The persons who find it will be very very rich. It's no doubt worth a trillion dollars or or two.

Nice find.

I'll be watching this thread...have you had it checked yet?

 

[luyluy]

I took it to get it checked but was dismissed as an idiot and turned away with a "probably just quartz" response. I have seen pieces of quartz as clear (like the ones you can buy in a gift store) but theyre a lot lighter for the size.

If you want to spend a little money to find out there are many testers out there.

"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....

real nice stone...

if a sapphire left a mark...it is not a diamond.

the scratch test just turns my stomach...
more diamonds have been ruined by people who scratch glass with them.
yes, diamonds are the hardest stone...that does not mean they can not be destroyed...take a cut diamond, scratch glass...look at diamond with loop...wow..where did the chips and fractures come from?
if you wish to explode a diamond into little pieces, drag it across the surface of glass.

one thing for sure, it is a beautiful stone...

pawn shops usually have a tester to chk out the jewelry they get. take it to one &ask if they will test it. I think you should send it to me, I'll give it a good home! good luck I hope it is real!!!

Google diamond finds, river finds. Diamonds will wear like a river rock, ie, round out. Reason I posted, I once found a clear, flat, "rock" while river fishing. Thought it was glass. In retrospect, it just didnt feel right for glass, ended up tossing it back in. Always wondered about that one. Can't hurt to check it out. Been many diamonds found in MI and WI. Not to mention gold, silver and copper carried down with the glaciers.
