A friend of mine sent this, I think it's Hematite. Just wondering if anyone has done anything with it and has any advice. Thanks. Yeah I'm a bit bored at work today. Thinking about going home, firing up the heaters in the garage and doing some rock stuff. Not a bad way to spend the day and ride out the blizzard, right? They just closed all of the highways in the Panhandle of Nebraska. Wheeeee.  |

If Hematite, could be polished with Dremel. Would be messy. Does a magnet stick to it?

I agree, it will be messy. Could also be goethite. IIRC, streak for hematite is red to red-brown, streak for goethite is yellow to yellow brown.

A streak test can confirm if it is hematite. You can use the underside of the toilet tank since it is unglazed porcelain. If it streaks red then hematite. A black or gray streak and magnetic would be magnetite. I have cabbed specular hematite.  DSC_0740 by James Sloane, on Flickr |

Agree with streak test. Perlite also looks like that in the black version.

It was a blackish grey streak, not magnetic that I can tell
I like the underside of the toilet tank idea, by the way!

Kinda looks like coal to me. Must be the picture, definitely not coal. It's super heavy. |
