[@pyroman] There probably aren't many Evenkites, though. It's already a rare enough mineral as is, but not to mention that it's incredibly hard to form a proper hydrocarbon crystal. Somewhere out there are probably failed Evenkites who weren't able to properly form and have become corrupted gems. Evenkite itself just barely passes as a properly formed mineral, and is currently the only hydrocarbon with a mineral form. And not to mention that Original Eve was a homeworld gem for quite some time, actually.
