Metal or mineral cube shaped?

[Duckshot]

I found a peice panning that I cannot identify.

No picture but I could write 1,000 words about it. It is a rectangular cube about five millimeters by four millimeters and about three millimeters in depth. On one side in one corner it has two similarly shaped cubes about 1-2 millimeters in size stacked on top of each other and staggered at about 30 degrees out of line with the lager peice. It. Is completely satin black in color. Came from either Georgia or Montana, iirc. Non-magnetic. I broke my little graduated cylinder so I do not have an exact density. Weight is about 5.35 grains.

Any ideas? I don't think I want to try a crush test. Thanks.

One picture IS worth a thousand words.

Yes. I'm about 880 words short. But if you can clue me in to what to look for that'd be swell, and I can answer any questions accordingly. Thanks.

Wrong color. This peice is jet black and it does not have any inclusions or concretions. It looks like a photo-negative of a grain of table salt.

Another possibility is chromite.

Does it look something like this?

There are A LOT of minerals with a cubic shape.

Couldn't get a picture off that page, but I read "Magnetite". This peice is likely completely non-ferrous. A castle hardware disease magnet affects it to no effect.
