Mineralesque - Fordite, also known as Detroit agate, is old automobile paint which has hardened sufficiently to be cut and polished. It was formed from the built up [sic] of layers of enamel paint slag on tracks and skids on which cars were hand spray-painted (a now automated process), which have been baked numerous times.

Natural Blue Obsidian (raw) Obsidian is a very, very special stone.  It is not a true mineral.  It is actually a volcanic glass that forms when molten lava cools too rapidly to crystallize.  It consists mostly of Silicon Dioxide.

Osmium is both the densest and the rarest element that you can dig out of the Earth. It's so hard that it's used (as an alloy) in places with constant pressure and wear, like the tips of fountain pens. One single cubic inch of this stuff weighs nearly a pound, and were you to somehow get a cubic foot of it, it would weigh over 1,400 pounds. Good luck with that, though: last year, the entire U.S. osmium production was only 165 pounds.

Osmium (Os)—the densest naturally occurring element One cubic foot of the stuff would weigh just over 1400 lbs, or about as much as a small car!
