I found something in the road. It's metallic and magnetic. Just curious if anyone can tell me what it might be. Photo here and here. Thanks.

Best answer: Hematite?

Best answer: I think it's magnetite, an iron ore. You see those kinds of polished pieces of it being sold sometimes in places like science museums.

Best answer: Yep, polished hematite. They sell them in museum gift shops for a few bucks for kids to play with.

Our local game store sells those as an impulse item by the cash registers.

I agree, it is hematite.

PS if you ever come across one of these hematite "singing" toys you should buy it, they are super fun.

Response by poster: Oh thanks everyone! At first I thought from its squarish shape that it might have some technological purpose, but I see now it must just be a gift shop item. I'll pass it along to the nearest kid!

or keep it in your pocket as a touchstone

One of the reasons these are neat is that it's very dense, so they weigh a lot more than we are used to rocks that size weighing.

(By the way, since my answer was wrong, I don't think I deserve a checkmark.)

I think some are confusing the mineral Hematite with a ceramic magnet, or man made Hematite .
I have a Hematite bead that I can barely pick up with a very powerful magnet, and I have a rattle snake egg that appears to be hematite but is actually a powerful ceramic magnet polished egg shape.
