Mission impossible.

[WHADIFIND]

I know this will be next to impossible to truly ID just from my lousy pics and info. But, heck, what's life without a challenge.

First a little background. I eyeballed this from about 50 feet away, (it might be more impressive when you see how small )
The sun was reflecting on it in that special way it does when something just out of the ordinary is there. With occasional flashes of fire, you know.

Here's some more info. It might not show in the pics too well, but it has a brilliant yellow color. Not metallic though. At least, not as far as I can tell. It's non-magnetic, it doesn't register on the metal detector, not even the pro-pointer. It weighs in at a whopping .1 gram.

Here's the best pics I could get. The dime is for size reference.


This is a little bit of the shine I saw but it was much bigger when I caught the sun just right.



At first I just thought a cleaved piece of metal, brass, bronze. But, doesn't register on the detectors. Two more aspects; when I use my diamond tester on it, it reads positive. (NO, I do NOT think it's a diamond. But, even though I know minerals a little bit, this has me flummoxed.) Also, when I try a scratch test on my gold testing tile, it doesn't streak.

Any ideas welcomed.
Thanks!

Looks like anthracite or silicon. Coal, for some reason, often comes up metallic on my AT Pro. Silicon is a metalloid, which means it has metallic properties but is not quite fully a "metal" element. Was it magnetic?

EDIT: Anthracite would make more sense, bc it read positive on your diamond tester. Diamonds are crystalline carbon formed under extreme volcanic pressure.

Looking at my pics, I can see why that might seem to be the case. But this thing is a very bright yellow.

Let me try another couple.



Sorry, but that's about the limit of my equipment and abilities. I even tried to take a couple thru a loupe.

Hope it helps.

Thanks!

Not so impossible after all. Confirmed, Iron Pyrite.

Thanks for the help!
