RE: Incredible Magnetite Octahedron's
Magnetite and it's non-magnetic twin, Hematite, are iron ores. So, yes, it is used, but seeing this beautiful structure I don't know how someone could toss it into a furnace and melt it down.
howdy again sir rt395! oh I agree, the ore you showed were stunning! I take it that it is rare to find it in that form?
